"But I don't like you as a lady!", Tim shouted as he shoved the surprised Katie down on to all fours, for a second she looked back at Tiff her former friend so lost in the haze of her own new form that she was willing to throw it all away to remain as she was. A boy. The look of shock quickly grew into surprise as Tim, no longer believing himself to have ever been a girl, slammed his cock home into her ass. For a few seconds, Katie went stiff as her body began to adjust to the feeling of having a boy's penis in her new form's ass, and that was when Tim began to ride her. In and out he went and with every thrust Katie's ass stopped feeling so in pain and more and more she began to feel the pleasure of being a woman again, but she didn't want this. She didn't want to be fucked in the ass, she wanted Tim to take her newly virgin vagina with his hard boyish dick. To Tim his endgame was very clear, he wanted Katie gone, and even though there was a part of him that remained attached to her feminine form he wanted his friend...no his lover back...and the only way to get him back was to break Katie's mind for good. And all that would take is for her to cum as a boy once more.
He chuckled to himself as he heard the beautiful Katie moaning underneath him and then began to ram it home as hard as he could, reaching down to play with her clit, and only her clit. Massaging it for all it was worth as she let out a shrill cry, cumming as a girl once more. For a few seconds Tim stopped and let the woman rest as Katie continued to shiver in pure bliss at the feeling of having her ass fucked and her clit played with. Time used this time to reach for something out of view of Katie, a can of "Little Bud Cola". He reckoned that a second dosing of this soda would cause Casey to return, but he would have to be tactful of how to get her to drink the drink again, as it was very clear that Katie wouldn't want to go back to being a boy again, but he knew that somewhere deep inside Casey would want to be free of his feminine cage. So, he began to buck his hips again into her, taking Katie by surprise, and making her purr in feminine pleasure as she felt the penis of her former best friend go in and out of her. She still felt empty, due to the nature of where Tim was thrusting, but at that point she didn't care, Tim was giving her some of the best pleasure she had ever felt in her life, and he didn't want her to stop.
Tim listened to her disgusting feminine mewing and silently popped the top on the can of soda, not that Katie could hear it over the haze of pleasure clouding her mind and her own feminine cries of pleasure. His plan was about to be put into action and he was going to rescue Casey from his prison no matter what! He pulled on her hair, eliciting another gasp of pleasure, and as her mouth was held open Tim bent forward and began to drain the contents of the soda into her mouth. She tried to close her mouth, but Tim's other hand reached over and held her mouth open so that every last drop of the drink poured down her throat. She began to spazz out, cumming almost instantly as Tim continued to thrust, and felt a familiar haze enter into her mind as conflicting feelings began to sprout through out her psyche. Tim knew it would take some work to coax Casey out of Katie, but he was going to his damnedest to get his "real" friend back. So, Tim flipped Katie over, still not having cum himself and continued to thrust in and out of Katie, denying her any feminine pleasure and refusing to rub her in any way outside of plunging in and out of her ass.
"Why Tim...why are you doing this to me...", Katie said grunting as she felt the soda begin to do its intended task all over again of morphing her back into a little boy. But Tim didn't say a word and instead watched Katie for signs of his friend again, he wouldn't have to wait long. Katie's throat began to spazz out as it had been the initial point of contact as she felt something pleasurably push out from her throat, forming a sort of adam's apple, and in that same quickness she began to feel her own vocal cords begin to rearrange themselves so that her voice was no longer her own. In fact with every thrust her voice sounded more like a boy's than a teenage bombshell that she had turned herself into. Inside of Katie's mind she was struggling with new thoughts that were just rampantly pushing themselves upon her. Thoughts of how her friend Tim was her gay lover and that she should feel honored that was the case, those thoughts of course fought against the thoughts of betrayal she was feeling at that very moment, after all he had forced her to drink more of that dreaded soda.
Tim could see a look of confusion crossing her face as he knew that conflicting emotions and thoughts were weakening her mental defenses against the pleasure. He looked down at her bouncing tits, much larger than they had been before, a pair of D-cups bouncing on an entirely female chest. He hated them, they didn't belong on Casey, and as he began to think that Katie began to squeal as she felt something begin to happen to her chest. She began to leak milk, this hadn't happened before, and it confused Tim, but Tim couldn't help but feel the need to suckle on these. After all, he was still quite a bit thirsty. "What is happening to me...OOOOO!", Katie began to ask as Tim leaned down and silenced her by beginning to drink from her feminine breasts. It felt weird to Katie, having her boobs being suckled, but she didn't seem to mind it as it was the first feminine pleasure she had felt in a while, but for some reason that feeling of feminine pleasure began to dull with each swallow of milk. Eventually she felt nothing at all and she looked down scared to see that her tits were shrinking with each gulp, but more importantly than that Tim was growing more masculine with each sip from her breast milk. But that wasn't the reason she was losing feeling, no the shrinkage actually felt really good, and it surprised her that it did. No the reason she was losing feeling was because of how her body was being overwritten, her nervous system was rewiring her internally to make her ready for her transition into man-hood. "My breasts...they feel...weird.", Katie said in Casey's voice causing her to cover her mouth.
Tim continued his efforts to get rid of the breasts as he felt them shrink down to a b-cup and he heard Casey's voice come from Katie's mouth. All the while he continued to thrust in and out of her feminine ass, but with each thrust he could feel it growing firmer, and losing more of its bounce. In fact he could tell that Casey's feature were emerging more and more with each thrust as he looked down upon the woman who had tried to cage up his lover forever. He stopped suckling on her chest, removing his mouth, and grinning at the woman beneath him as he continued to thrust into her. "Lets finish getting rid of these shall we?", Tim said as he reached over and tweaked Katie's still feminine nipples on her chest causing Katie to let out a damn near perfect replica of Casey's moans which frightened her, but turned Tim on even more. Milk began to spew all over the place as her breasts continue to deflate, but something inside of her told her it was okay, after all tits were a bad thing for a boy to have. Her eyes went wide in shock as she realized that her mind was being invaded and pushed to the side by a growing persona deep inside of her, she knew who it was, and she tried her best to fight against it. In fact she began to try to shove herself off of Tim, but Tim's newfound body granted by drinking Katie's milk allowed him to keep her in place.
Tim stopped tweaking Katie's nipple as the last dribble of milk left her breasts or rather his chest as there was nothing remaining of the D-cups that Katie had made for herself, in their place was a flat masculine chest that belonged to a young boy. He grinned at his handiwork, but knew he was far from finished with his job of freeing Casey from Katie's control. Inside Katie was struggling as she felt an odd swelling in her clit and an urge to begin to push something out from inside of her, but she knew better and resisted with the best of her might to stop the advance. It was then that Tim began to play with her clit, which had swelled up into an inch of length before Katie had even noticed. "What's wrong Katie...losing your grip? I thought you liked being a lady.", Tim taunted cruelly as he only worked on her clit for a while which felt more explosive than anything she had ever felt before. For a few seconds Tim didn't thrust and instead focused on helping Casey's penis be born from Katie's virgin vagina, it didn't take long for Katie begin to lose the fight as she felt her clit swell into action aching for some kind of release. She began to feel less and less like herself, almost welcoming the changes that were piling on to what remained of her feminine body, inside the voice of a young boy began to talk about how it would be better to be a boy than a lady. That it would be better to not have to worry about female things anymore, like makeup, and periods. No, it would be better to become what she...no he...was really suppose to be. Katie blinked as something broke inside of her mind as he felt his penis finally free from the disgusting vagina that he had once wanted so much to have.
Tim noticed that the mind of Katie had been broken, but he still referred to himself as Katie, it was time to deal the finishing blow to that personality, and have Casey finally be free. "Time to have you become who you really are.", Tim said as he reached down and began spread Katie's still feminine lips apart to help speed up the process. As he did so Katie's mind went into overdrive as his face began to warp and contort into the face of Casey, becoming more angular than round like a female, and in his mind he was fine with that. In fact as the urge to push entered into his mind, he could hear a little voice begging him to not do it, but Casey would not be denied and he began to push as hard as he could as the only part of him that was still Katie began to dissolve into nothingness, being pushed out to make way for all that would be Casey. Katie screamed inside as Tim began to thrust again, his dick pulsing, and the feeling of his vagina becoming inverted was all it took to finally cum for the last time as a woman and embrace his manhood. Tim came deep inside of Casey's ass as the last of Katie was obliterated as with a wet plop her ovaries, having turned into Testicles slowly, plopped down into the waiting sack that had once been Katie's vagina.
Casey opened his eyes from the most extreme orgasm he had ever had, his stomach covered in his male seed, and his best friend and lover in the world hovering over him with a smile on his face. "Thanks Tim...", was all Casey said as he passed out in pure bliss. Inside Casey settled in, new memories flooded in as Katie's memories, and mind flowed into a dark corner where she had put Casey earlier.
