[M4FB] [M4MtF] My gay best friend x-changes himself into a girl and gets stuck as one

NSFW

I never thought my best friend in college would be a cute gay boy but after our first meeting in the campus gym, it couldn't have gone any other way. I noticed you over in the corner of the campus gym which was surprisingly quiet that day. I could see you squatting with some poor form and as a friendly guy I decided to go over and help. We were total opposites, I was a muscular, masculine, pretty typical college jock and you were a small, cute gay guy clearly trying to work on his ass. Despite our differences, I happily helped you out in the gym and we became gym buddies.

After a couple weeks of this, we were just friends. I began inviting you to a few of the parties I was attending and tried getting you some hookups with other gay guys I knew. What I didn't realise is that you were rejecting all of those guys because you really wanted me. I probably didn't help, I always complimented you on your looks. I always said if I was gay I'd be fucking you already, and as we got closer I even starting giving you some friendly smacks on the ass whilst saying 'no homo'

Clearly I wasn't actually ever going to make you mine and I was far more interested in the airheaded girls at the parties I attended. This started getting to you and you began trying to find anyway possible to get me into bed with you. Soon enough you found something. Through your Biology degree you had some access to various pieces of scientific research and found some cutting edge research on something called 'x-change pills'. According to the research, this pill would change your gender for a day, making you biologically the opposite sex. It sounded perfect to you and you were desperate for an answer by this point.

You decided to take the pill and the next day you were transformed into a beautiful girl, the exact type that would get my attention. Tonight there was a party on that I was going to as well, it was coming together perfectly. The second you stepped into the frat house, you stole my attention. I thought you looked a little familiar, but my dick was doing all of the thinking.

After some brief conversation we left the party together and I took you back to my on-campus apartment. For the whole night, I plowed and pounded you exactly how you had wanted and by 4am we were both spent and cuddled up in my bed together. It was the best sex of my life and it was with my best bro.

The next morning you expected to wake up to be back in your male body but clearly something went wrong. You woke up and you were still a beautiful, busty girl.
