As the water was running I heard Jennie ask where I had got to. Her dad told her that I was just getting a glass of water before turning in for the ni...ght and that he would stay and read a little while longer.“I’ll go on to the bedroom, dad, and wait for Caroline there. Good night again. See you in the morning.”“Okay sweetie, have pleasant dreams.”“Oh, I will daddy, I will.”I waited another minute or two and then came out. I walked up to Mr. White, who drew me even closer to him, lifted my. Finley smiled and said it was okay with her, as long as Annie wasn't being a pest and it was okay with Beth. I told her that she was being the perfect guest and she caught on that her daughter wasn't a virgin anymore. How she did that makes me believe in mental telepathy. She grinned, then went and got me a box of Trojans and I left, rather bemused by how totally cool this older woman was about what was surely a very unusual situation.Annie and Beth were cuddling under the covers when I came in. I playfully twanged the string and she wriggled beneath me, laughing.'If you don't want a white line, this ought to go' I said, twanging the string again.She turned her head and sort of looked at me over her shoulder. There was a grin on her face as she said 'Can't have that can we, Dad. Undo the bow at the side and pull it away.'I pulled at the bow and the knot fell apart. The string across the back fed through a loop at the top of the centre string, so I pulled it through and let it fall to. All of a sudden, the dildo in my ass started vibrating, right on top of my prostate. Then she got up, and left.Minutes passed, and I felt nothing but the fullness in my ass and gentle waves of pleasure coursing around my prostate. I started to get frustrated quickly, my hands tied behind my back, my cock wanting to get stroked, my ass in the air. And nobody around to release me. Nothing but the vibrator in my ass, humming away. Minutes and minutes more. Every minute that passed, the pleasure in.
