Hot drunk threesome with my bro turns bi [MMF]

This story happened about a year ago when me and my mate Ryan were 21, was a Saturday night and we had a party to go to that night hosted by a friend of a friend. I’d been snap chatting Ryan along with a few of my other mates talking about how we all wanted to fuck some girls at the party that night, me and Ryan were having a laugh about how we were both going to shave our balls and trim our pubes just incase we managed to find some girls to fuck at the party, the joking about shaving each other’s balls will be relevant later.
