I remember first time I had a cock in my mouth, we were at a swingers party and I was under her while she had this monster cock in her pussy and sucking two more. He was fucking her hard and his cock and balls were soaked with her cum. Right when he was about to cum she shifted and he came out of her pussy and right into my mouth. At the same time he came, fuck it was so amazing! I could taste her pussy at the same time I could taste his cum. He tried to pull away at first but my hands were firm on his ass at this time. It was so exhilarating feeling his cock pulsating, he had so much cum. He went from "stop, Im straight" to fucking my mouth until he came again. Since then there has been nothing taboo for us!
