Jeff feels the same sensation as he starts the program up again. When he enters the new world, he finds that he is fully incapable of doing anything but hearing, tasting, and feeling. The world is completely dark to him, and he doesn't have any way to breath, or a need to do so.
His body feels weird too. Flat, but not flat. Hollow may be a better way to describe it. But he still felt thin. Suddenly something pushes down into his left leg, filling the void entirely while stretching every inch of his leg out snuggly. The filling moved up his left leg, then began in his right foot as well, filling it out and moving up his right leg to his waist.
He then felt his dick get pushed back into itself, until it poked out the opposite side, now inside something warm and moist. Thinking more about it, his legs are also feeling some warmth radiating off of whatever is filling them out too.
A new sensation caught him off guard as something around where his asshole should be is suddenly pushed as well, and similarly to his dick, is also inverted upon itself and shoved into something. His ass is then stretched over something as his midriff is pulled flat against something as well. It's like sand is being slowly poured inside his hollow shell of a body in order to fill him out.
Again, a new sensation happens as a pair of heafty weights suddenly load themselves into his chest, with their weight and size causing him to stretch a bit as he is made to tightly conform to their exact shape and size.
Then like his legs, his arms get filled out in a similar manner. Then finally, the tail of his spine tingles and then runs up his back, stretching his body even tighter around whatever is filling him out.
His hands begin being moved around as he is made to walk around somewhere. His feet are then placed inside something sturdy that presses against them and whatever is inside of him. His toes are bent down and this new exterior pressure is extended up his foot and calf to just past his knee. Then it happens to his other leg too.
Still not entirely sure what is going on, Jeff tries to listen for any clues, but can only hear a clacking sound and someone breathing. Though occasionally he does hear the sound of rubber being rubbed too, but that isn't consistent in when it happens. The clacking happens when his foot feels like it is striking against something and the breathing is in sync with the rise and fall of the weighted sacks in his chest cavity... wait.
Jeff suddenly gets an idea about what he is. He hears a door open and someone else enter the dark room as a second pair of clacking sounds out. Then he feels something running over his hips and squeeze his ass as his chest is pushed against a pair of soft orbs with a pair of hard points. The sound of rubbing rubber can be heard in excess as his body gets caressed and brushed against by the other thing.
This new thing feels like human hands though. Only further solidifying his guess. If he isn't mistaken, he has become a woman's latex condom suit, complete with a pair of built in condoms for her pussy and anus, and form fitting enough to hug against her every curve. The clacking has to be the thigh high heels she now is wearing. And from the angle his foot is bent at, either they are just super tall with minimal flat toe space, or they are ballet boots.
The other sensations must be from her partner. Probably a woman in a similar outfit if he had to guess going by the sounds. His user pressed his hand against her partner's leg and worked its way up to her crotch where a strap was felt. Then his hand wraps around a rod of some kind that seems to be quite familiar. The other woman giggles and rubs something cool and gel-like inside of his dick pocket that's currently shoved into his wearer's pussy.
"There, now your all lubed up. What do you think, ready to take my strap-on?" Asked the other woman. That woman then pushed Jeff's user down onto something soft, probably a bed if he had to guess, and spread his legs apart. His user, now down on all fours on top of the bed. Begins wiggling her ass for her partner. Jeff can feel how she starts rocking back and forth, dragging her own pair of erect nipples across the bed spread.
Then something solid is pressed into his dick pocket, filling it up entirely to the point he worries that it might rip. It feels insanely good though, and his entire body begins experiencing a minor buzz of pleasure as a whole too. Even his fingers and toes feel pretty good and the sound of latex on latex intensify as the other woman mounts his woman from behind and begins fucking her with the strap-on.
To Jeff, it feels as if he is both fucking his wearer while taking a dick himself at the same time. His wearer's tits feel like his own, and he begins fantasizing that he is this woman and not just her latex condom suit. He feels his wearer's body change over the course of their sex. Her breathing and heart beat quicken, while she begins sweating too. And still Jeff feels as if he is her. He is the one panting, begging her partner to keep going in between her loud moans. Her tits are swaying and bouncing around beneath her as she continues gyrating from all the fucking. It's her oussy that is being stuffed, and her ass that is begging for some love too.
Jeff feels her lover slap her ass and shove a finger into her unused hole. She hears a moan as she twitches her asshole around the finger buried within it. Jeff may be more aroused now than she was back when she was being milked as a dairy cow. Something she never thought would be even possible.
The sex keeps on going until the familiar feeling of reality breaking down returns him back to his real world with some extremely intimate knowledge about some unknown woman's body and possibly a new fetish for being some woman's clothing durring sex.
