I have never read or heard of anything like that - in the way you describe, with precision, the way you position yourself touching two guys at once.

That said, reading the OP makes one think of a sexual encounter with two males and one woman - not the kind of that people arrange online with random strangers or anything like that, but with two men who know each other very well and a woman whom both of they are fond of - maybe one more than the other. Maybe one crazily in love with and the other just fond of - that kind of situation. I have not had an actual experience with it but I can see myself having this kind of experience under appropriate circumstances. Has it ever occurred to you that you might be at least fantasizing along these lines?
