The only time I did a tag team type thing was when a friend of mine and I had a 3some with my girlfriend at that time. Unfortunately I did not know how big he was. Much, much larger than me. Took him awhile to get into her while she tried to blow me. But when he actually started fucking her real hard there was no way she could continue to suck my cock. She had never before orgasmed from just penetration, but she came after about 5 minutes. He then told me to take over, and that is where the humiliation came in. He had stretched her out so much that she could barely feel me. She finally told me to get off and to have my friend continue to fuck her. That's when he really laid into her......if you know what I mean. She screamed and bucked like I had never seen her, or almost no one ever do. So, that is my kind of story of my only gang bang.
