"In the ass," i said without thinking.

"Oh really?" she said with a grin. "Well, I had no idea you were such a dirty slut."

I'm not really sure where that came from, but I decided to go with it. After all, this wasn't exactly a normal night. I got on my knees and aimed my ass at her.

"Damn, I do have one sexy ass," she said, then slapped my on one ass cheek.

Susan positioned herself behind me. I felt the head of her cock against my asshole. I heard her pull the end table drawer open and get something out. A moment later I felt a squirt of cool liquid in my crack.

"That always helps," she said and then pressed against me.

I'd never been fucked in the ass before, but I had fucked a few women in the ass. It always goes about the same. There's the first moment of pain, as the asshole tries to maintain it's exit-only status. Then a mixture of pain and pleasure as it expands, letting the head in. With a little pressure and a little time, it finally opens and lets the rest of the cock in.

"Fuck, no wonder guys practically beg for this," Susan said. She started fucking me and I started to cum. I buried my face in a pillow and started to scream. "Thats right, take it."

I started to squirt, spraying the bed. Susan grabbed my hips and thrust hard, filling my ass with cum.

We collapsed on the bed and lay in each other's arms.

"Can we stay this way?" she asked.

"Please."
