Your mom loved it, and by "it" I mean the alcohol laced semen I ejaculated into her rectum.
Through my dick, which was in her ass.
What I'm trying to say is that I got drunk and then fucked your mom in the ass. She liked it, but providing her with pleasure wasn't the actual intent. All I cared about was busting a nut, and she was handy.
Your mom was all like, "Mosh never does this (she meant you never fuck her in the ass) anymore!".
