[F4M] An Experimental Drug + A Nerd Who Has an Obsession Over His Crush = A Man Who Becomes Addicted to a Growth Hormone and Now Has Control Over The Love of His Life

NSFWTransformation ✨

It had been tough, dating was obsolete in school for you. No one wanted to date the nerd. Of course, the only person that really mattered was Katie. She was a few years younger than you and had always been so sweet even despite being pretty involved with school activities and organizations.

As you went off and graduated your mind had slipped from her mostly but you had decided you wouldn’t be the same nerdy wimp your whole life. In college you managed to get a personal trainer, even involved yourself with enhancement drugs which caused significant muscle growth but also height and everything else. You didn’t even look the same. 4 years had passed and you had gotten a degree and conveniently you had gotten a job at a firm in your hometown.

I (Katie) had graduated a year before and was clueless that you had returned. Of course everyone went to the Friday night football game and you were thrilled to show up and show what you had become. I was being side hugged by a guy I had been dating while we watched the game, but the moment you saw me all the feelings you had rushed back…..the desires you had flooded your mind and now even some new fascinations were beginning to form including the feeling of jealousy. This girl may have slipped away years ago, but now you would make sure she was yours….whether she liked it or not. Boy friend or not, she was going to spend her life with you and build the happy little family you had always wanted.

Of course once you started you couldn’t stop, you managed to steal her away but the drugs kept coming. You kept taking them, your desires higher and your growth continues, your height, your weight everything. You were becoming a giant and now you knew she could never escape you.

(Just a basic start to a long term plot. Come with your creative ideas and let’s build something fun and suspenseful! Here you can probably tell I enjoy a dominant/controlling male which your character wasn’t always but through lifestyle changes and maybe even the use of drugs you had turned into a typical jerk but one that only has eyes for his crush from school that now is growing into more of an obsession. Also, I will be playing a human character but feel free to play whatever you want; human, anthro, monster, etc))
