With her fingers around my stiffie, she would gently push my foreskin back exposing cock head. After she finished washing it, she would pull my foresk...n back covering my cockhead. I remembered how I would laugh and squirm and tell her it tickled. I don't recall being embarrassed. I thought it normal and just something all parents did.When I saw mom later that evening, she asked me how my day went and that's when I told her about my chat with Bill and how we both were reminiscing about being. She saw me looking - and as she passed the bottle to me, she licked her fingers and smeared that Mexican Pussy Oil all over her nipples.I was still staring at her naked titties when she bumped my naked chest with the bottle. I looked down and my shirt was gone. I saw it folded and laying across the seat back, but I couldn’t even remember taking it off. I’m not even sure I did.When I held the bottle up to see how much was in it, I saw maybe one, possibly two good swallows left in it.Hell, I just. ”“Good. We might need it again.”We took the materials back to the motel and, before doing anything else, we moved.

There was a little placard on the desk, listing the restaurants in the area, and which ones that delivered. We called KFC and asked them to deliver our order.Then we delved into what turned out to be Professor Noel Wilson’s. I didn't really go to sleep, but I lay there a long time without moving as I enjoyed the sensation of having my cock in my sisters mouth. I was a little surprised at how soon my cock began to revive, growing harder and harder as the head pushed further into the back of her mouth. All the while her tongue kept slowly running up and down the shaft.I think she was enjoying giving me a long slow suck as much as I was enjoying getting it. When my cock was fully erect again she moved her mouth up to.
