Experimented with my Fraternity little who is gay [MM]

This story is completely true and happened less than a year ago.

So I’m a straight, 20 year old male. I have a soft spot for sucking a big, hard, smooth dick though. Like when i’m on Adderall I can only get off on thinking of being blasted by a guys cum all over my body and in my mouth.

So story, and i know this is a fetish for some people so many will like this.

I’m in a fraternity that I won’t name on a big college campus. Well I have three little brothers, one of which is gay. We have always had a super casual relationship and nothing beyond brotherhood and friendship. Well one time, we both took a shit ton of adderall during finals and went for an all night study session in the library. We got a study room and it was just me and him, no windows. Now he has never shown any attraction to me whatsoever, but i just started having these weird fantasies about his dick for the reason i stated above.
