Yes
After being pegged by my wife for weeks. We had discussed this and one night her bull brought a bi friend. I was penetrated while doing missionary with her.
It felt like my cock would explode and desintegrate. She said it was the best hard on I got and she loved feeling my dick in her. I don't know if I came from fucking her or being fucked by the black guy. We all came in a short difference of time from each other, but their screams were the loudest. I felt like my virility flowed down her pussy, leaving behind a sister rather than a husband to her.
I had this before but I was not completely consensual. My then female partner set me up with some black friend of hers during a sex party. I thought I recovered from that.
