The unseen hands guided Bob over to the sofa, where they gently but firmly sat him down. One pair of hands lingered for a few moments longer, as though savoring the touch of his skin. He shuddered as he felt fingers running across his exposed chest and down the inside of the silken robe he wore. He continued to look from his left to his right, expecting, hoping to catch even the tiniest glimpse of his two female visitors. But it was futile; all he saw was the emptiness of the room.

"Ohhhhh," he moaned, softly, closing his eyes, shaking his head slowly from side to side. "This is just so weird…!"

"Relax, Bob," Stephanie’s soft, reassuring voice said from near his chest. "Jusssssst…relax…"

"I—I don’t know about this," he said, opening his eyes to find—not unexpectedly—nothing where he knew a woman should be. "This is just—"

"I know, I know," Debbie’s voice said, coming from the vicinity of the nylon bag sitting on the coffee-table. "You’d feel better about all this if you could see us…right?" A short pause. "Right?"

"Well…um…yeah…!" In spite of himself, a smile crept to Bob’s lips, as he savored a mental picture of what his two invisible female guests would look like if he were able to see them just then.

A soft giggle sounded as though Bob’s thoughts had been read, and the nylon bag shifted slightly by itself, as though it were the source of the laughter. "Well…" Debbie said. "I think we can take care of that…"

Bob’s smile faltered slightly. "What are you going to do?" he asked, slightly bewildered, yet eagerly anticipating what had been hinted at.

"We’re going to get ready!" came the answer, as one brightly-colored silk bundle suddenly floated up from the coffee-table, tumbled about in the air for a moment or two, then fluttered softly back down again. It all happened so quickly that Bob was unable to identify precisely what it was. But whatever it was, it looked enticing, for the brief moment it fluttered into view. "Right, Steph?" Debbie giggled.

"Oh, but Deb…!" Stephanie’s anxious voice said. Her unseen hands held fast to Bob, as though reluctant to let go.

"Now, now, Steph. We have to think of our boy here. After all, it’s only fair that he should get to see something…right?"

Stephanie paused for a moment before answering. When she did, Bob had the uncanny sense that she was smiling. "Right," she conceded at last, with just a tiny trace of disappointment. Bob then felt a slight movement, as her unseen presence withdrew from his side.

Moments later, the small bundles of silken cloth that lay strewn about the coffee-table, floated up and fluttered about in mid-air, tumbling end-over end, as though they were going through the spin-dry cycle of a giant, unseen clothes-dryer.

"We’d planned on being visible when we brought all these things with us." Debbie’s voice said from a fluttering blur of black silk. "But…well, things didn’t quite work out the way we planned… But that doesn’t mean we can’t still use them! Know what I mean?"

"That’s right, Bob," Stephanie’s voice said, now coming from a second silken bundle, this one pale pink in color, as it likewise floated up from the coffee-table. Like the first, it proceeded to flutter about in mid-air, as though it were caught in a whirlwind, as Stephanie unfolded it. "We’ll make the best of it. It’ll be fun!"

The two bundles of silken cloth carefully unfolded themselves in mid-air, then floated high up into the air, before gently drifting back down again. As they descended, they slowly, sensuously slithered onto transparent, slender, yet distinctly feminine curves. Bob’s eyes opened wide, as he recognized the floating, disembodied clothing as two nearly-identical sets of lingerie, made of what appeared to be either silk or nylon. They consisted of floor-length gowns of semi-transparent floral-pattern lace, with thin spaghetti straps, over which were worn robes of matching colors and materials, which likewise reached to the floor. Bob watched spellbound, as the empty sleeves of the robes moved with the uncannily lifelike and sensuous motion of unseen female arms beneath them, as the empty lingerie carefully drew themselves onto transparent shoulders.

The two outfits were clearly designed to reveal specific, strategic portions of a woman’s anatomy…although in this case, all they revealed was the transparency of their wearers, thus appearing to be completely empty. Through the thinnest parts of the garments, where one might normally expect to catch a glimpse of breast or thigh, Bob could only see the empty interior of the garment itself, or the other side of the room behind it. Bob was disappointed…and yet simultaneously fascinated by the sight.

The empty sets of lingerie continued to primp and preen themselves, seductively so, with a uniquely casual air of self-confidence, characteristic of extremely attractive young women, behaving as though they were completely oblivious to the eerie sight they presented to their male host. And the sight was eerie, there was no question about that. It frankly gave Bob gooseflesh to watch it. And yet… it was also strangely and paradoxically sexy as well.

At the last, when the two negligees had finished dressing themselves upon the transparent curves of their wearers, they each leaned over and drew from the interior of the nylon bag two matching pairs of clear Lucite platform slides with high, spiked heels. The pink nightgown held up one of these shoes at the end of an empty robe-sleeve, holding it up for Bob to see. "Hey, Bob," Stephanie’s voice said. "Check these out! They’re see-thru! Get it? See-thru?" She giggled, though whether from the cleverness of her own comment or from the look on Bob’s face as he stared open-mouthed at the floating shoe, was difficult to determine.

The two empty negligees then drifted casually over to the arms of the sofa, where they sat down, on either side of Bob (whose head swiveled repeatedly to his left and right as though he were watching a particularly lively tennis match) and slowly slid the platform shoes onto unseen feet, deliberately prolonging the action once they realized the captivated suspense with which it held Bob’s attention. For Bob, it seemed almost an eternity before the simple task was completed. When it was, the two nightgowns then stood up and glided over to stand directly in front of him. He continued to stare, thoroughly enraptured, at the empty silk garments hovering before him, as he looked first from one to the other. He reached his hands out to touch them, as though to convince himself that, yes, there really were flesh-and-blood women somewhere inside the empty garments. His touch confirmed the fact, as he felt the familiar sensation of soft, warm female flesh beneath the seemingly-empty semitransparent silk.

Even the sight alone of the well-filled out lace silk held Bob fully spellbound. The curves and contours of the silken material seemed to contain shapely, sensuous waists and hips, the upper portions seemed to contain breasts of considerable dimensions. And yet…that same material was clearly empty, apparently containing nothing but air. They weren’t empty, Bob knew; the touch of his fingers clearly told him that. And yet there was nothing there to be seen. The curious paradox of knowing there were breasts there (good-sized ones at that, he could tell by their feel), mere inches from his eyes, and yet being unable to see them, left Bob with a vague feeling of frustration, almost as though he were being cheated somehow, or as though he were somehow the butt of a bizarre practical joke. It was an uneasy feeling, to be confronted with an object of desire that was almost—but not entirely—there.

"Well, Bob?" said Debbie, in a soft near-whisper. "Like what you see?" She and Stephanie both repressed giggles.

Bob discovered that he was unable to speak. Though his mouth now hung wide open in amazement, no words issued from it. Instead, he merely nodded—very slowly—in evident, enthusiastic approval, as the corners of his mouth pulled upward in a very satisfied smile.

"Ohhhh, man…" he softly whispered when the power of speech at last returned to him, and his hands continued to stroke and caress the unseen curves beneath the silk. "This is absolutely incredible! I still can’t believe it…!"

"You can believe it, babe," Debbie said, as she reached an empty black sleeve out to Bob’s face. This time he didn’t even flinch when he felt soft fingers caressing his cheek. "You can believe it…because the fun’s just beginning!"

"Just one final detail," Stephanie’s voice said, as the pink robe drifted back to the nylon bag, bent over, and reached a sleeve into its interior. The bag rumpled about for a moment or two, as though a hand were rummaging through it, before retrieving a tiny spray-bottle. Stephanie held the bottle aloft in her hand. Bob marveled at the way it seemed to just hover in space at the end of her sleeve. The black robe drifted over to join the pink, took the tiny bottle and sprayed a fine mist upon the transparent chest and shoulders of its wearer. The pink robe then took the tiny bottle and repeated the motion on itself.

For Bob, it was the last straw. The faintest hint of the fragrance hit his nose and the last remnant of resistance within him broke down and fell away. He was at the point now—a point he’d come to know only too well in his life—where he knew—beyond any doubt—that he simply had to have these two women, and that nothing in the world would dissuade him from that goal. Still, with practiced ease, he managed to hold part of himself in reserve. Though he knew what would inevitably follow, he feigned a slight degree of aloofness, the better, he knew from experience, to turn on his guests.

The pink robe returned the tiny bottle to the nylon bag, then both it and the black robe reached out their empty sleeves to Bob. He felt the same soft hands he’d earlier felt now clutching his arms, gently but insistently tugging him up onto his feet. Very little force was necessary, however, as Bob was by now more than willing to follow the ghostly hands wherever they chose to lead him. In the fraction of a second, he was on his feet and following the empty lingerie as they drifted out of the living-room. Once out in the hall, they paused, as though lost. Bob hesitated for a moment before speaking

"What’s the matter?" he asked.

Both robes folded their sleeves in front, almost in a gesture of impatience, and Bob had the uncanny feeling that the two empty robes had somehow exchanged glances with one another.

"Well?" Debbie’s voice said, in a mock-serious tone, from the empty space above the collar of the black robe. "Aren’t you going to show us to your bedroom?"

Bob grinned ear-to-ear. "Of course!" he said, nodding eagerly. "Right this way, ladies!" With that, he took the lead, guiding his unseen guests to the staircase, up the thickly-carpeted stairs to the second floor, and into the master bedroom.

Once the trio stepped into the lavish master bedroom, Stephanie let out a tiny gasp, followed by a prolonged sigh. "Ohhhh, wowwww…." she breathed, stretching out the empty sleeves of her robe, as though to embrace the entire room. "This is your bedroom? Wowwwww… This place is bigger than our whole apartment!" Stephanie continued to circle the bedroom, drinking in the general ambiance of it, every inch of which seemed to live and breathe male sensual power, and which seemed to have an extremely powerful aphrodisiacal effect upon her hormones just then. Debbie, on the other hand, felt guided by a much more single-minded purpose, taking little notice of the lavish furnishings, with the exception of the king-sized bed, located right in the center of the room, for which she made a beeline, dragging Bob along by the hand.

The black robe stopped at one side of the bed, while Bob circled over to the other, and together, they pulled back the bedspread and covers, revealing shiny black silk sheets underneath. Now it was Debbie’s turn to gasp and sigh. "Ohhhhh…!" she breathed. "Hey Steph! Check it out! Black silk sheets!"

The pink robe now drifted over to join the black one, and together the two invisible women continued to ooh and ahh over the silken bedsheets, caressing them with unseen fingers. Bob watched in awe as the ghostly impressions of fingers appeared in the glossy surface of the black silk, stroking it and savoring the sensation for several seconds, before the unseen guests suddenly remembered what it was they were there for.

"Well," Stephanie said. "What are we waiting for? Let’s try them out!" More giggles erupted as Bob’s unseen guests quickly kicked off their platform slides, pulled back the cool, crisp, silken sheets, and slid between them, with Bob following immediately after them. Even with three people under the covers, there was still plenty of room to spare in the enormous bed. Out of habit, Bob positioned himself so that both his guests lay on his left. The empty pink robe soon rectified this matter however, as its wearer positioned herself on Bob’s right. Now Bob found himself surrounded by negligeed, invisible women on either side of him. He reached out his arms and held both women close to him, and they in turn, wrapped their arms around his head, neck, shoulders and chest, and proceeded to nearly smother him with kisses, as though they were hungrily devouring him.

"You’re—um—um—" were the only words that Bob managed to utter, as his nose, lips and tongue probed the unseen cleavage beneath the pink silk.

"I’m Stephanie, in pink; Debbie’s in black," a soft, breathy voice answered Bob’s unfinished question.

"Right, right," Bob whispered in reply.

While the pink robe kept Bob’s upper half occupied, exchanging passionate kisses with him face-to-space, the black robe disappeared under the covers and immediately began tending to Bob’s lower region. Bob then felt the delightful sensation of his loins being lovingly and expertly caressed by hands and lips. His eyes rolled back in ecstasy.

But he felt somewhat conflicted, however, undecided between keeping his eyes open, or keeping them closed, so as to avoid the eerie (and thus distracting) sight of empty nightgowns hovering over him. The sight was eerie, yet it was so uncanny that Bob found it difficult to tear his eyes away from it. As his face and chest were lavished with kisses and caresses from the unseen Stephanie, Bob closed his eyes again and tried to remember what she looked like, from the brief glimpse he’d caught of her the night in the hospital. His recollection of the incident was so foggy however, that he ended up relying more upon imagination than specific memory. He held her close to him in his arms, his hands running up and down her slender sides.

The hips beneath the empty pink gown began to press themselves ever more insistently upon Bob’s abdomen, gradually grinding its way lower and lower, until hipbone almost met hipbone. When they had almost met, there sounded a muffled, yet rather annoyed, voice from beneath the blankets:

"OWWWW!! Hey, Steph, watch it! You almost kicked me in the face!" Debbie protested.

"Sorry," Stephanie replied. "But you got in my way."

"Smart-ass," Debbie muttered quietly, after which there sounded from beneath the blankets, a crisp little slap, such as that of a hand smacking a person’s backside, to which Stephanie responded with a tiny yelp and a jump.

"Hey!" she said with the tiniest hint of a giggle, more in surprise than irritation, as though the slap was not entirely unexpected or unwelcome.

"Let that be a lesson to you," Debbie muttered, although Stephanie was clearly no longer listening or in the mood to respond, as she had by now resumed her passionate embrace of Bob, again smothering him with kisses, and resuming the progression of her hips down Bob’s abdomen. Debbie thoughtfully positioned herself to Bob’s side, well out of the way of Stephanie’s intended course of action.

At one point in the proceedings, Bob opened his eyes a tiny crack and he suddenly found himself staring straight down the empty interior of the pink silk robe and gown he held in his arms. In spite of himself, the sight startled him, and he jumped slightly.

"Oh, man...!" he whispered. "This is just too weird…! I can—I can see right down inside you…!"

"I know, I know…" Stephanie’s voice whispered from the empty space above the collar. "Just…try not to think about it…" The unseen lips returned to their earlier task.

"But…but I can see myself…sort of." Sure enough, as he looked down the empty interior of the robe, he saw a part of himself, urgently pressing itself against the silken folds of the robe, as though struggling to break through.

"Here, wait a sec…" The unseen lips withdrew as Stephanie pulled away from Bob momentarily, straightening up. The sleeves of the robe reached down and raised the hem of the nightgown up to the level of an unseen waistline, well above the area of her nether regions.

"Now…" Stephanie breathed, returning to her earlier position over Bob, again settling into his welcoming arms. Now no longer hindered by the silken barrier, Bob’s body was free to proceed in the manner for which it was intended.

Gradually, the eerie sight of Bob’s ghostly visitors became less and less distracting and threatening to him. Indeed, his initial feelings of unease were gradually replaced by a sense of familiarity, as he recalled his night in the hospital several weeks earlier. Little by little, he began to feel more comfortable and familiar with his guests, and with that feeling of comfort, amorous feelings within him likewise continued to increase as well. It was initially very awkward for him at first, when it came to estimating exactly where he was kissing, for example; he kept aiming for the mark —and missing it by mere inches. Repeatedly, his lips reached for the area of empty space above a collar, expecting to make contact with lips but occasionally connecting with a nose or a chin by mistake instead. Bob felt extremely awkward, working, as he did, at something of a disadvantage. But in time, he gradually got the hang of it, and in fact, it almost became a kind of game after a while as, little by little, he drew closer and closer to the mark with each new attempt. Eventually, most of the initial difficulties were overcome, as the threesome continued to explore the unique sensations of invisible sex.

As Bob continued to hold and kiss his two ghostly lovers, the primary emotion he felt (in addition to the obvious one) was one of wonder and amazement, at being able to touch, kiss and caress soft female flesh that was almost…but not quite there; at being able to touch and feel a pair hefty, good-sized breasts, even with erect nipples, when to look where the breasts should be, there was clearly nothing in his hands to be seen.

In the case of Debbie and Stephanie, the primary emotion they felt was one of exultation, at being in a position of complete control of the situation, with the freedom to take the initiative at virtually every stage of the game (which they freely did.) For some reason, this feeling, of being in control, seemed to further stimulate their already-formidable sex drives. Indeed, as they realized the enormous potential of their unique condition, they seemed to get hornier and hornier as the activities progressed. Thus, it was Debbie and Stephanie who were the primary assertive partners, sometimes each one acting independently, but more often the two of them working together in concert, each administering special attention to a different part of Bob’s body. The attention lavished upon him was often so intense and passionate, that Bob felt at times as though he were in danger of being completely overwhelmed by these two powerful tsunamis of invisible female passion.

Repeatedly, Bob’s two ghostly lovers switched positions, first with Stephanie tending to his upper region, kissing his face and chest and offering her transparent breasts to his eagerly awaiting hands, while Debbie simultaneously tended to Bob’s lower regions, only to have the two women abruptly switch positions when it suited them. Bob couldn’t be sure…but it seemed as though they somehow calculated the timing of these changes of position to coincide with what felt like his imminent release, thus delaying it and keeping him in prolonged, yet increasingly-impatient ecstasy/agony for as long as it pleased them to do so. Several times, Bob had almost reached the very threshold…only to have his guests suddenly, abruptly stop…and decide to switch places. More than once, Bob found himself moaning, "No, no, no…not now…! Just a couple more seconds…!" Then, once they had taken up their new positions and assumed their respective new tasks, they gradually worked him back up to the desired level of excitement.

After the initial encounters between Bob and each of his ghostly lovers, other variations and experimental positions were tried. It turned out, in fact, (and much to Bob’s surprise) that his guests were actually far more imaginative and even adventurous (and, evidently, experienced) in this regard than he was. And it was not always a two-against-one arrangement, either; for a few times, at least, Debbie and Bob explored each other in one-on-one exclusivity, while Stephanie took a short break. Other times, it was Stephanie who had Bob all to herself, while Debbie simply watched (and, to be perfectly accurate, she often did more than merely watch.)

After an especially passionate one-on-one session with Stephanie, she suddenly withdrew from the bed and stood beside it. At the same time, Debbie rose from the chair in which she sat, watching the proceedings.

"Now?" was the single word spoken by Stephanie, barely suppressing a giggle.

"Now." Debbie replied calmly.

"What now, ladies?" Bob said with a satisfied smile, as he propped himself up on one elbow, looking over the by-now familiar sight of the empty nightgowns standing beside his bed.

"We’ve got one more little game we’d like to play," Debbie replied.

"Oh? What’s this one?"

"It’s called…" she stifled a laugh. "’Guess who I am!’" With that, the empty sleeves reached up and, in an instant, the black robe was pulled from the transparent shoulders beneath, and slipped to the carpeted floor, leaving the empty black nightgown alone in its place.

It took Bob a delay of only a few fractions of a second before he realized what was happening. Immediately, he was stirred from his satisfied drowsiness, and became instantly alert, yet unable as yet, to coherently voice any objection.

"Um…um…what…what are you…doing?"

"Just adding an element of mystery to the game," said the black nightgown as first one thin spaghetti-strap, followed by the other, gently tugged itself off of a transparent shoulder.

"Ummm…maybe…maybe you’d better not do that…" a slight quaver appeared in Bob’s voice.

"Oh, come on, Bob!" Stephanie’s voice said from the pink gown, as it followed the example of its counterpart, slowly sliding the thin spaghetti-straps down and away from the unseen shoulders beneath it. "It’ll be fun!"

"Yeah, but if I can’t…I mean, how can I tell you two apart?"

"That’s the whole point!" Debbie’s voice said from the black robe, as it promptly collapsed to the floor, revealing nothing but thin air, where, only moments before it held the well-filled-out shape of an enticing female figure. "Think how much fun it’ll be! All the time, you’ll be wondering… is it Debbie you’re holding in your arms…or is it Stephanie…?" From the sound of her voice, Bob felt that she was smiling as she spoke the words.

"That’s right, Bob!" Stephanie’s voice said, picking up the cue. "That’ll be for us to know and you to guess!" With that, the pink gown, like the black one, promptly collapsed to a crumpled heap on the floor, and with it also fell away the last remaining visible trace of Bob’s visitors. To the naked eye, he now seemed to be alone in the cavernous bedroom, yet the sound of conspiratorial giggles reminded him that he wasn’t.

"Um…um…Ohmigod!!" Bob jumped as the bed-covers suddenly began to draw away from him, pulled back by unseen hands. He stared awestruck as the impressions of unseen fingers appeared in the shiny black silk of the sheets, as they drew back by themselves. The ease and comfort with which Bob had come to feel with his ghostly guests quickly vanished along with the last visible trace of them, and he now felt his earlier apprehension once again rearing its ugly head. For some reason…his guests seemed less threatening to him when he could see them (or see their clothes, at least.) But now that they were naked and therefore completely invisible once again, it was a whole different matter. Now it was downright spooky, even spookier than being seduced a pair of empty negligees.

A set of deep impressions suddenly formed in the soft mattress; a moment later, a second set of impressions appeared, joining the first. Bob drew a sharp intake of breath as what felt like a ghostly finger, from out of thin air, made tentative contact with the exposed portion of his chest. A soft giggle sounded from a short distance before him. Another finger touched him, this one more firmly, lingering just a bit longer with its caress. Then another…and another, each one accompanied by the sound of a delighted giggle. Soon, the unseen fingers were once again all over him, exploring and caressing every inch of his flesh as if for the first time. Bob had another flashback to his night in the hospital. Unlike that night, however, he was now wide awake and most definitely not under heavy sedation, and as a result, the sensation was now a bit more unnerving than the earlier experience had been. His heart began to pound madly at every unexpected touch and caress of a ghostly finger, and with every touch, he noticeably flinched, which seemed to only encourage the disembodied, ghostly laughter even more.

"Ohhhhh, poor Bob…!" Stephanie breathed heavily from somewhere in space near his left ear. "Even now, after all we’ve been through together, he’s still intimidated by us…aren’t you? Awwwww, poor baby…!" Despite the soft, reassuring tone of her voice, it also seemed to contain just a tiny trace of mockery to it. Or at least, that’s the way it seemed to Bob just then.

"Shhhhhh…shhhh…it’s okay…just relax…" Debbie’s soothing voice whispered from somewhere in front of him, only inches away from his right cheek. "We’re not going to hurt you…but we need to get this thing out of the way."

At that, the sash of Bob’s robe suddenly sprang to life, as its ends floated up and writhed in the air like two snakes. "Ohmigod…!" Bob gasped, starting to raise himself up on his elbows, as if to make a fast escape.

"Shhhhhh…jusssssssttt…relax…" Debbie’s voice whispered from the air, as the remainder of Bob’s robe likewise came to life, slowly, deliberately tugging and sliding itself off his shoulders, down his arms and off his body, thereby making him as naked as his two guests.

"There now," Debbie’s voice said when the task was completed. "Isn’t that better?"

But before Bob could answer, unseen lips again pressed themselves against his from out of the air, smothering whatever reply he might have offered. He reached his hands out and touched slender shoulders; reaching upwards, his fingers felt a long, slender neck, and what felt like shoulder-length hair. Yet when he opened his eyes, he saw nothing except his groping fingers, only inches from his eyes.

Out of the corner of his eye, he saw the bed-covers suddenly lift themselves up, as an unseen object seemed to disappear beneath them. Something seemed to be moving around under there, near his waist. Moments later, Bob felt the by-now-familiar sensation of Stephanie’s lips making contact with the lower portion of his body. Unlike the earlier such encounter, however, Bob was slightly less enthusiastic, now that each physical contact came as a complete surprise to him, without even the most rudimentary of visual clues to prepare him for their touch.

Debbie noticed Bob’s unease, of course. "Awwww, you are still afraid of us…aren’t you?" her voice breathed heavily before him…somewhere.

"No, no, I’m not afraid, it’s just that…" Bob began to protest, then cut short by the solid placement of a warm, wet tongue in his ear, before gliding down his neck and chest, causing a shudder to run through his body. "It’s just…well, it’s a little difficult for me if I don’t have something I can see and focus my attention on…if you know what I mean."

"Yes, men are more visually-oriented when it comes to lovemaking than women are…aren’t they?" Debbie said, repressing a delighted chuckle. "Well, don’t worry; we’ll take care of everything!"

"Uh—umm…"

"Hush, now," Debbie’s voice said decisively, as unseen fingers pressed firmly against Bob’s chest, gently forcing him to lie flat. "Just leave everything to us…"

"Ohhhhh…myyyyy…gaaaaahhhhhdddddddd…" Bob managed to exhale in on long breath, his eyes rolling back in his head for the umpty-umpth time of the evening, as the unseen lips and tongue smothered his face, neck and chest with renewed vigor, and a second set of lips and tongue tended to his lower region. The hours of romantic play had done nothing to diminish the sensual energy of Bob’s unseen guests. All over again, Debbie and Stephanie lovingly toyed with Bob as though he was their own personal love-doll, their fingers ravenously devouring the touch of his flesh, as though there simply wasn’t enough of him to satisfy them.

Soon, however, and to his own surprise, Bob’s momentary panic and apprehension again began to subside, as he discovered that the total invisibility of his guests had its share of unique pleasures as well. In fact, he now began to appreciate the enormous erotic potential of a totally-invisible partner (or partners), potential which he and both his guests were only too willing and enthusiastic to explore. Just as Debbie had predicted, Bob could never be entirely sure which girl he was holding in his arms at any given time, and he was therefore free to speculate and imagine who it might be. Realizing this, Debbie and Stephanie played along with this new game, choosing to remain silent, lest their voices give away their identity. Then, only after that particular round of the game had been concluded, only then would the active participant identify herself, with the revelation more often than not coming as a complete surprise to Bob. Similarly, there were other times when he reached out his hands to the empty space, never knowing whether there would be unseen flesh there to meet his touch or not or which partner it was when his fingers did make contact or what part of her body his fingers made contact with. Again and again, he reached his hands out, expecting, hoping to touch a particular part of female anatomy, only to discover an entirely different one awaiting his grasp instead. It essentially became a prolonged game of group-grope, except that Bob was at a distinct disadvantage.

And there were other surprises for Bob as well. Sometimes he found himself started by what felt like a pair of large, pendulous breasts unexpectedly descending upon his face, gently cradling his nose between them; other times he felt the tendrils of long, unseen hair brushing against his face and cheeks, occasionally getting in his eyes—to which he protested, while the unseen owner of the hair laughed and promised to move the offending hair out of the way, only to repeat the action, much to his annoyance. It seemed to Bob almost as though she were doing it on purpose, deliberately trying to annoy and provoke him. All these constant, ongoing surprises (both welcome and not-so-welcome) made for quite a varied and interesting game, providing an added element of surprise to the prolonged love-games.

But as the afternoon wore on into the evening, and darkness fell across the room, the question of Debbie’s and Stephanie’s invisibility became a moot point, as Bob chose to leave the lights off. The novelty value of making love to two invisible women was, for him, beginning to wear off just a bit. Notwithstanding his adjustments to it, he nevertheless realized that he was at a disadvantage, and soon discovered that he functioned much better in the dark, where he was no longer constantly reminded of the unique status of his lovers. Nor was he distracted by the sight of the two seemingly-empty nightgowns—however strangely sexy the sight may be—or the eerie sensation of being fondled by unseen hands from somewhere out of empty space. No, now that the playing-field was more or less equal, Bob was at last able to act on pure instinct, finally taking on a more assertive role in the lengthy lovemaking session. He finally began to perform with his guests in more or less the same way he normally would with any attractive woman (or women) in his embrace. To him, they were no longer invisible women, but simply women. No longer was he the passive toy of his ghostly guests; he now became more passionate in his actions, more forceful in the kisses and caresses he exchanged with them. His initial hesitancy and even timidity before the unique status of his spectral female guests finally began to subside as, after some initial groping about in the darkness, he managed to locate first one, then the other, of them. From then on, everything went strictly routine. Again and again, Bob rose to the occasion, performing the role for which he had repeatedly received such lengthy and loving preparation by his ghostly visitors. Once, twice, several times, first with one, then the other, until all were satisfied, to the point where it seemed that no higher levels of satisfaction could be reached—but were, as the games continued with renewed vigor, and only occasional short rest breaks in between the action.

Hours passed in this fashion, and by nightfall, the three players were quite exhausted from their marathon lovemaking session. For an untold length of time, they rested peacefully (if wearily) beneath the covers of the enormous bed. Debbie was the first to emerge from her weary semi-slumber. She reached over and switched on the bedside lamp, dimming it to a low level, so as not to awaken Bob, who now snoozed peacefully beside her, then sat upright on the edge of the bed, pulling the robe of her negligee over her shoulders. Even though hours had passed, she, like Stephanie, still remained invisible. She looked down at Bob and smiled at her snoring host. On Bob’s other side, Stephanie began to stir as well. Debbie glanced up and watched, amused, as the covers on that side of the bed began to squirm and rumple about by themselves, as if alive, as her friend groggily emerged from under them. Like Debbie, Stephanie also pulled the semitransparent robe of her negligee over her slender but still-invisible shoulders. She yawned widely, and, like Debbie, sat upright on the edge of the bed. Both women looked down and smiled with deep satisfaction at their sleeping host. Debbie was the first to break the silence.

"He’s really something, isn’t he?" she whispered to her friend.

"He sure is," Stephanie whispered in reply.

"Doesn’t disappoint, does he?"

"Mm-mmmmm…." Stephanie hummed a satisfied, negative reply. Then a thought occurred to her. "How many times has that been, altogether?"

"Ummmm…eight or nine, I think."

"Eight or nine???" Stephanie gasped in disbelief.

"Well, yeah," Debbie replied, offhandedly, as though stating an obvious fact. "’Cuz, let’s see, I was with him twice, you were with him three times," She counted off on invisible fingers. "So that’s five… Then the three of us were all together another three or four times, I think… So, yeah, that’s eight, at least, right there."

Stephanie sighed in impressed amazement at Bob’s stamina. "Incredible… You know, I’ve heard stories about him, but I never…" She giggled, as though embarrassed to finish the sentence.

"Aren’t you glad now that we came?" Debbie asked with an unseen grin.

For an answer, Stephanie broke into fresh giggles, then Debbie followed in like kind when she realized the mistaken meaning which her friend had taken from her words. Both women tried to hush their giggles, so as not to awaken their sleeping host.

"No, no, I mean, aren’t you glad I insisted we come here today!" Debbie corrected herself belatedly.

"Yeah…I know what you mean…" Debbie replied, her hushed giggles subsiding.

"It was worth it, wasn’t it?"

Stephanie nodded—then felt foolish, realizing the gesture was useless when done by an invisible person. "It sure was…" she said simply.

Debbie paused a moment before continuing. "So… are you happy?" Debbie whispered.

"Mm-hmm…" Stephanie replied contentedly, then fell silent.

The two invisible women sat in silence for several more minutes, Debbie quietly gazing at the contours of the pink silk robe draped around the invisible form of her friend.

The silence was finally broken by the sound of Stephanie drawing a deep breath, yawning. She stretched her arms expansively, raising the seemingly-empty sleeves of the robe over her head. "Geez, what time is it, anyway?" she whispered, at the conclusion of her yawn.

"Oh geez, it’s late," Debbie replied, glancing up at the clock, out of Stephanie’s line of vision. "It’s almost nine-thirty."

"How late are we going to stay here, anyway?"

"Well, we’re not going anywhere until the formula wears off, so we’ll have to stay for a while, anyway."

"Yeah, but how much longer? I mean, do we count on spending the night here or what?"

"Nothing wrong with that, is there?" Debbie replied, with a stifled yawn. "Why? You think he’d kick us out?"

"No, no, of course not," Stephanie said hastily. "I just mean, how long do we count on staying? I mean, I don’t have to get up early tomorrow morning or anything, but…"

"Well, how strong was the dosage you prepped?"

"Umm…I don’t remember exactly, but it was pretty strong. Very little dilution, in other words. I wasn’t taking any chances."

"Mmm, I thought so. It felt pretty powerful to me; and it took effect almost immediately. So…let’s see…" she glanced at the clock on the night-stand beside the bed. "I figure it should wear off by maybe around midnight or so."

Stephanie whistled. "So we’ve got about another three hours or so of invisibility."

"Something like that, give or take."

A brief silence followed, then Stephanie stretched and yawned again. "Well…what do you want to do now? I mean, we’ve still got some time to kill." She paused. "Wanna fool around with him some more?" She jerked an unseen thumb in the direction of the source of the snores.

"Mmm, maybe we’d better not. I mean, look at him. He’s sleeping so peacefully…" Debbie giggled again. "I think we wore him out, the poor guy."

"Oh, really?" Stephanie said, as she reached out an empty sleeve to Bob’s sleeping form. She gently patted the blankets over a certain area of his body, which responded immediately to the touch, forming a miniature tent in the covers, although the cadence of his snores never missed a beat. "Oh, will you look at that!" Stephanie giggled in hushed tones. "Man, can you believe this guy? Even sound asleep, he’s still ready to go! Jeez, you can turn him on just like a light-switch!"

"Now, now!" Debbie said, now giggling in hushed tones as well. "Let’s not be greedy! Let’s let the poor guy sleep. After all," she yawned and stretched as well. "There’s plenty of time for more later on, if we want."

"Yeah, I guess you’re—" Stephanie’s words were interrupted by a sudden thump, coming from somewhere under their feet. "What the—what the hell was that?" she whispered.
