Unexpectedly, Jon felt the red panties peeled away from his face, as if Karyn had been reading his thoughts. She shimmied her panties down her legs, kicking them off into the laundry basket across the room like a seasoned professional. Jon's entire perspective shifted dramatically. Now he was looking not at the floor but facing straight ahead. Karyn was lying on her back with her knees up and her skirt flipped back. For the first time since had become a part of her body, Jon could see the world around him unobstructed, and it took a moment to get used to the brightness of it all. Just in front of him were her bare feet, with her calves looking like enormous columns framing his view of the bedroom. Now that he could see, he realized just how small and insignificant he really was.
Directly in front of Jon, across the room from her bed, he could see Karyn's reflection in the mirror on her dressing table. Her pretty little muff was on full display. Jon was startled by the realization that he was looking at himself.
"It's so good to finally see you again. We're going to have so much fun tonight."
Jon was confused. Was she talking to him? He didn't remember wishing for her to be aware of his condition.
"I was worried Jon would have done something weird with you. I tried texting him this afternoon but he never answered back. Looks like you'll be getting the action he was going to get."
Karyn spread her legs wide and Jon felt fingers teasing him from each side, twirling in the blond curls on what felt like his cheeks. Jon had never grown a beard, but now he wondered if having one would feel anything like Karyn's pubic hair did. A finger ran downward across Jon and slipped inside. The sensation was little different than having his lips and mouth touched, but having his lips be vertically oriented felt pretty bizarre, and the finger in his mouth felt amazingly sensual. She withdrew it, a narrow strand of what looked like saliva trailing from her fingertip to Jon's mouth. Was he already this wet? He hadn't realized how turned on she was, but suddenly he was aware of a warmth spreading across him and a puffy sensation in his lips. His nose tingled and seemed to be swelling somewhat.
Karyn's hand rose out of sight. Jon heard moaning and the sound of lips smacking. Was she tasting herself? Jon realized that he had never really seen Karyn masturbate before. She had fingered herself for him before, but that was just putting on a show and he had no idea how much of it was just acting for his benefit. But now Karyn was alone, as far as she knew, and everything she was doing was for Karyn. Something about this gave Jon a voyeuristic thrill. Seeing her acting this way without knowing she was being watched made it seem so much more intimate. And he wasn't just watching, he was going to feel it too.
The hand popped back into view, now clutching something. Jon immediately recognized the toy for what it was; it was the object she had retrieved from his house. A week prior, when he and Karyn had been studying together in his bedroom, he had fished a big pink dildo out of her backpack, much to her mortification. He had refused to give it back, saying she didn't need it when he had something of his own for her to play with. After a few minutes of teasing her and holding the toy out of her reach despite her embarrassed protests, the gambit had, amazingly, paid off. Not only did he get laid, he'd kept the toy as a trophy. But now she had it back, and it was glistening with lube.
Had Jon eyes, they would have been as wide as saucers at the sight of Karyn's dildo. It was realistic, with molded glans and thick veins. It was also fairly large, considerably larger than Jon's penis, much to his annoyance, but what mattered right now was that it was pointed directly at his face and looking absolutely enormous. There was no way that thing could fit inside him, as small as he was.
As the dildo neared, Jon wanted to cringe and pull away, but again, as part of her body, he was going nowhere. Karyn spread Jon's lips with one hand and guided the tip in with the other, and then it was inside him. Jon felt like gagging. He had wished to be a vagina, this was exactly as he expected it to be, it was the very sort of thing he had fantasized about, but now that it was his reality, he wanted to be anywhere else. His entire self was stretched tightly around this silicone monstrosity. Even though it wasn't a real penis, Jon had never felt so emasculated as he did with this thing buried to the back of his throat.
Karyn eased the dildo out gently, almost all the way out but not quite, and then back in, beginning a rhythmic thrusting. Her fingertips danced upon the tip of Jon's nose -- her clitoris -- now so sensitive the lightest touch made him feel like squirming with delight. Jon clenched involuntarily around the hard plastic in his mouth. It was beginning to feel a bit more comfortable inside him as he loosened up. Somewhere in the back of Jon's mind, a part of him was enjoying it too. As uncomfortable as it was to be stretched so wide, there was something pleasantly satisfying about feeling so full. Was this the way penetration always felt? Karyn had always felt so tight when they had sex. Jon could only hope that his own dick gave her as much pleasure as this toy did.
The fingers' tempo quickened, stroking Jon's lips and circling his nose. Jon could feel Karyn's body heat rising now. It had been a cozy glow at first, but now he was burning up. Beads of sweat sparkled in her blond bush. Over the squishing and smacking sounds of urgent female masturbation, Karyn was breathing heavily, her ragged breaths interspersed with the occasional muffled groan. Few things turned Jon on like Karyn's bedroom noises. Every purr and cry that escaped her lips when they had sex only drove him to go at it harder than ever. Now, even in the role of passive observer, Jon was getting just as worked up by Karyn's anxious moaning as he did by the work of her practiced hands.
Before he even knew it was happening, Jon spasmed hard around the intruder in his throat. Karyn's orgasm washed across him like a tsunami and for some seconds the world ceased to exist. There was only warmth and fullness and delight. The experience was overwhelming beyond anything Jon could have imagined. Maybe the female orgasm was several orders of magnitude greater than the male's, or maybe the sensations were amplified now that Jon's entire existence was essentially an erogenous zone. Maybe it was a combination of both. Either way, Jon's mind was blown. For a while afterwards, Jon really was nothing more than just a vagina, incapable of comprehending any concepts more complicated than desire or bliss. Until he recovered, all he could do was bask in her afterglow.
Karyn stretched languidly across her bed, catching her breath. She idly stroked the plastic phallus in her hands as she savored the residual warmth radiating from her sex. She wasn't the kind of girl who played with herself on a regular basis, especially now that she had a boyfriend who was happy to service her at the drop of a hat, but every once in a while it felt really good to take hold of the biggest toy she could find and simply go to town on herself. Looking down between her legs, she caught a glimpse in the mirror of her wet, puffy vulva, with its throbbing clit and tangled pubes. She had really made a mess of herself. But since she was already in such a state, and she had nothing else to do...
Jon had always been amused by how quickly Karyn wanted more after her orgasm. The girl could be practically insatiable when sufficiently turned on, and on multiple occasions he had worn out both fingers and tongue bringing her to one climax after another, rarely taking more than a minute's break in between. Making her scream and squirm for hours did wonders for Jon's ego, but he had always felt a twinge of jealousy, wondering what it would be like to not have a refractory period of his own. Now he was about to find out, and it was going to be a long night.
