My "straight" friend and I went on a road trip together and he knows that I'm bi and he has a girlfriend. We were chilling In the hotel room and I go take a shower and while I'm In there he sneaks up behind me and starts to kiss my neck and I freak out wondering what he's doing in my shower naked and he said that he has always loved me and I couldn't help myself so I start to make out with him and we give each other head and then he turns me around and starts to fuck me and then he wanted me to fuck him also so I did and it was fucking amazing and now were still on vacation and were holding hands and kissing in public... Am I in a relationship with my straight best friend?.. What should I do when we get home because he has a girlfriend. Advice much needed were both 16
