a little over a week ago me, my girlfriend, her friend, and her friends boyfriend had group sex together (didn’t swap) and his dick was much much bigger than mine and i’m already a decent size. during that my girlfriend had looked at his dick quite a bit and i said she could suck it which she then nervously said no. well about the middle of this week she told me she wished she had sucked his dick and we even had her friend send us a picture of it. so this weekend came around and we had group sex again except with about an hour or so session of my gf and her friend giving him head in lots of different ways and positions. at one point i started fucking my gf while she shared his dick with her friend and it was probably the fastest i ever came. i had to watch them share him for about another 15 minutes before he finally came on both of their faces
