Basically I (21m) hooked up with this couple that was a mtf trans and a guy- it was so hot bottoming, because she was very feminine, sexy tits and good proportions, very smooth, but she had this big fuckin dick, and he was so nice and encouraging as my fucking jaw almost dislocated on his dick. I walked in and immediately started sucking her off. After a while, she suggested we wake up her bf with a bj. That was one of the hottest things I've ever done. While I was bent over sucking him off, she came behind me and started fucking my ass, which I was not ready for. Frankly it was such a haze of them using me that I don't remember many details, but I've been dreaming of doing that again since
