How I messed up the ending of my first threesome (in high school) [MFF]

This is a story about how I fucked up my first threesome. It was the high school senior class play wrap party (all participants were 18). My family owned a hunting cabin deep in the Poconos woods, about two miles back behind our home off a single lane road, that we rented to New Yorkers during hunting season, so the party (like many others in high school) was in the empty cabin.

This takes place in 1975. I’d been in all four class plays during my high school career. I don’t know if it was like this elsewhere, but with all four there was always a lot of random making out during rehearsal breaks. Girls with steady boyfriends not in the play would just start pawing and kissing me, or someone else. There was no intercourse or oral, but a LOT of petting and under clothes grouping, finger blasting, and the like. This could happen four or five times a night, with different pairings.

It was always confusing for me. Five or ten minutes of lust and then, when rehearsal ended, it’s like it never happened.
