The first time we tried this he was fucking my wife and she wanted him to fuck me. We agreed and with my cock in her mouth he pushed his cock up my ass and started fucking me. I got so fucking hard it hurt and talk about cumming. I put so much cum in my wifes mouth. We did it again with a trusted relative who was straight but he had fucked his stepmom before. It was strange for both of us but exiting all the same.
