When Karyn returned she burst through the door with a confidence that Jon had never seen before. Not just on her, but on anyone. She strutted inside in her little black negligee that barely went past her hips and still gave Jon a pretty good view of the skin it supposedly covered, anyway. As her hip swung, it caused the hem to flutter up, giving Jon a clear view of the black lace panties underneath.

She walked in like she owned the room. Not just like this was her bedroom, but like she commanded authority over everything inside. Her body language said that this room belonged to Karyn in every conceivable meaning of that word.

And the room obliged. It didn’t need physical contact from Karyn anymore. Jon found his attention drifting to those pieces of the bedroom that still reminded him of the original Karyn, as one by one they changed. Furniture changed from wood grain to shades of pink. The pair of overalls slung over her desk chair became a sundress. The desk chair, itself, turned white and gained leather upholstery. Jon looked down as the sheets he sat on shifted from green to pink, as the pillows behind him multiplied from two to six, as a canopy sprouted from nowhere to cover the bed.

“Hey Jon,” Karyn purred as she stepped closer. “Eyes on me. I’m the center of your universe right now.”

And, god help him, he obeyed. Jon turned his eyes away from the changing scenery and focused them squarely on Karyn’s swinging hips, her incredible cleavage, her legs that went on forever and a week, and she came closer and closer. Every step was a transition from being the center of Jon’s universe, to simply being the entirety of Jon’s universe. With a coquettish smile, she shimmied right up to where Jon sat at the side of her bed, and pushed him so that he was lying flat on his back on the pink sheets of her bed. Then she slid down and undid his pants.

His dick was already fully erect, and practically popped out at its full length, just under five inches, as soon as Jon’s zipper was down. Karyn reached out a hand and began stroking Jon’s rod, applying a gentle touch before grasping it fully, wrapping her fingers around the shaft.

And it grew. It didn’t get harder. It was already at its maximum length. But this was Karyn’s domain. This was her room. And everything in that room changed on her whim, changed to be what she wanted it to be.

Jon could feel that something more than just a hand job was happening to him. There was a pulsing in his loins that had never come with an erection before. But when he tried to raise himself up on his elbows a pain shot through his ribs that forced him back down.

His dick was a full inch longer when Karyn lifted her head up high enough for Jon to see, smiled a predatory smile, then opened her mouth and took in six inches at one go.

Jon’s eyes nearly crossed themselves, and not just at the sensation of Karyn’s mouth on his member. The pulsing intensified, turned his entire length into a single raw nerve. He could feel his flesh pushing outwards against Karyn’s lips, pushing her jaw to open wider in order to accommodate it.

If Karyn noticed that Jon’s dick was growing even as she held it in her mouth, she gave no indication. She just pulled back and pressed back down, back and down, and then slowly, agonizingly, she drew her mouth back up the length of Jon’s shaft, dragging her tongue along the bottom as she went.

Jon didn’t even have context for the feelings he was experiencing as one inch of his flesh hit the cold air. Then two inches. Three. Karyn pressed her palms on the thighs of Jon’s pants for leverage as the fourth inch became exposed. Then the fifth. Karyn straightened her elbows and shifted position so she could sit higher and release the sixth thick inch from her lips. Seven.

And then with a pop, the head was free, and Karyn’s eyes glistened as she looked down as the great spear before her poked straight at the ceiling. It was long enough now that Jon could even see its tip from his position laying back on the bed.

Danger alarms sounded in Jon’s head. He’d gotten his head around Karyn’s changing personalities. And even watching the objects in Karyn’s room change, that made some sort of sense. But now he was changing, and he didn’t have any context for that. He didn’t know what it meant.

Jon tried once again to get up, but Karyn placed a hand on his chest and looked him deeply in the eyes. “Trust me,” she whispered.

It was the combination that did it. Karyn’s words. Jon had been thinking about trust so much, that when she asked him to trust her, he wanted to. But also, even though Karyn’s press would have been gentle at any other time, it placed just enough resistance against Jon’s chest that any more movement on his part was painful. He could only move back down into his place.

But the third, final thing, the thing that had been affecting him without his realizing it from the moment that Karyn burst into the room in that little black negligee, was Karyn, this bitchy version of Karyn, this mean, nasty, selfish version of Karyn slowly imposing her will on everything in her room.

On everyone in her room.

Once Jon was settled back down, Karyn returned to his hips and slid his pants and his boxers down his legs. Then she came back up and lifted the blue turtleneck over his arms, past his head, exposing the rubbery bandage-like material wrapped around his chest. And then he was naked, on his back, with an incredible eight-inch erection that he had no clue what to do with.

But Karyn knew.

She climbed up onto her bed on her hands and knees, straddling Jon, hands at either side of his head, pussy poised just above the tip of his cock, teasingly close but just out of reach.

A sickening thought entered Jon's head in that moment, despite the overwhelming sensations coursing through his body: he was about to lose his virginity in his best friend's bedroom, but not to his best friend. To some strange doppelganger of his best friend. This moment was supposed to be important. It was supposed to be meaningful. It didn't need to be with his real Karyn, but it almost felt like he was being used. Like this version of Karyn didn't see him as a person, just a thing to be conquered.

Karyn stroked a hand through Jon's newly-barbered hair, and a tingle followed where her palm traced over his scalp. It was a tingle that burrowed deep down into Jon's head, he could feel it penetrating inside of his brain. And for a moment, he forgot what he'd been thinking about.

Right. Karyn. She was about to take advantage of him. And that thought was exciting, wasn't it? Or hadn't he not wanted this, for some reason.

Karyn's hand pulled through Jon's hair once again, and the tingling sensation returned, followed the same path, burrowed deep into Jon's mind and wiped out his thoughts.

And then he realized that Karyn's boobs were there just in front of his face. That he could look straight down her hanging cleavage, under the black lace of her bra and the bodice of her negligee. And he smiled. It wasn't a smile Jon was used to making. It was a lecherous smile. It was the smile of someone who wanted to take something that had not been freely given.

He stopped. This was wrong. Something was happening to him. He needed to regain control.

Karyn slid backwards, her butt rising farther into the air, her nipples caressing Jon's chest, her hands slipping over his shoulders, down to his collarbone, sweeping over that rubbery material on his chest that seemed to dissolve at her touch.

Jon gasped. He could breathe fully once again. His chest didn't start hurting when he filled his lungs with too much air. After a moment he could feel something further than that. He felt better and stronger than he ever had before. Like not only had his broken rib healed, but he'd put on a thick layer of muscle everywhere that Karyn touched.

And it felt so good. It felt like liquid sunlight was being poured into his soul. He wanted more of it. Jon let out a slow breath that bordered on a moan, then raised his arms to test out his shoulder muscles. They were more responsive, more precise, than he could ever remember them being. He put his hands on Karyn's shoulders and looked up at her with an expression of devotion that flickered for just a moment as whatever remained of the original Jon fought its way back to the surface.

Then Karyn leaned forward and landed the kiss to end all kisses. Jon's entire face, his entire head was engulfed with the feeling of a freight train rattling down the track. Of rolling thunder that echoes across the night sky for an entire minute before the volume starts to fade. The feeling that a Bengal tiger gets inside its own skull as it lets out a mighty roar that causes every other animal around it to flee.

When their lips parted, Jon's face was fully healed. And his jawline was sharper. And his neck was thicker. His eyes shone with a purpose that Jon had never felt before, and his assertive, aggressive little smirk matched Karyn's perfectly.

"I want you," Jon growled.

"Good," Karyn replied. "I want someone who wants me."

Then Karyn dropped her bottom down, and Jon's shaft slid perfectly, elegantly inside of her, and everything that Jon was, everything that Jon knew, every desire and every need dropped away, as the entire focus of his being centered unyieldingly onto the girl who was riding him like he was the last horse in the world.
