Even if you're tired I'll put it in your ass

The other day my boyfriend was tired, I did not know if he could fuck me, but I insisted that he relax and let me masturbate and caress his eggs. And if he was not aroused enough, I begged him to let me fuck him in the ass. It was too hot and I wanted him, fuck, I ran into his ass and was amazed by the torrent of semen that I left there in there.
