He hasn't been with two people at once... we usually round it out with an even number... 4... and even 6 once... what a splendid time
I'm glad to say I've never had a gf who has been railed by two guys at once... it would definitely bother me that I couldnt fulfill every fantasy she had alone I guess (and wanted to enact)... but I've done FFM once... nothing I need to do again tbh.
yes, my boyfriend had a 3some once. at first when we started living together we were very open-minded about sleeping with other people, so after a long party he had a mmf 3some. and after that he decided he doesn't need to sleep with other people. i have never had a 3some but i'd like to - though i'm not sure if i'm ready for two guys
