The bottoms I've known who really enjoy gang bangs are insatiable for cock & cum, especially after a long, thick cock like mine has fucked them with a good prostate massage until cumming. The best gang bangs I've been part of were all impromptu at group parties rather than planned. For planned, it's hard enough to get enough guys to show up at the same time for co-ordinated serial fucking. The best one was when 7 of us rotated fucking a tall, lean, cock-hungry bottom who was so hot that we all got overheated by the 3rd time around. The others we rotated 3 times while one of us fed the bottom a cock while keeping him from getting fuck-pushed around the bed; starting with the 4th time around, we would fuck for about 5 minutes each trying to make the bottom cum hands free, which once took 5 of us rotating fucking 4 more times. When one of us succeeded in fucking him to cum, we usually spontaneously cheered and then would not let the winning top stop fucking until he bred the bottom deep.
