Sam explains and continues

From Torg Adventure

Sam popped my cock out of her mouth and explained, "That little display upstairs got me so horny, Dan. I've been waiting for a chance." She took my length back in her mouth and resumed sucking and licking it.

"But what about your sister?" I whispered, not wanting to use her name in case she awoke from hearing it. I was freaking out, but kept my voice calm.

"Didn't she ever tell you we shared guys a couple times when we were in high school, before she met you?" she asked with a sexy smirk. She watched my eyes as she flicked her tongue on my fat tip. I closed my eyes briefly and moaned softly.

"Oh, Sam. Your mouth is amazing. Ah!" I exclaimed at the end because Sam began playing with my balls.
