This was getting to me in a big way. I wasnt going to last long and so I told her so. Jenn just looked down at me and with a smile that said pure plea...ure. Then she quickly popped of my cock to move onto all fours with her ass and pussy towards me. Fuck me from behind! I pushed my hardness balls deep into her and pumped slowly has I knew this wouldnt last long, but I wanted it to last. Just I thought I was in control I felt her grab my balls from between our legs. She was so good with rubbing. Waking up after an evening of intense sex was a quiet joy. Frank loved looking at Jennifer's peaceful face in the morning while she was still asleep. Her tousled hair and slight sounds she made made her look very young. Sometimes her eyes moved under the lids, and expressions drifted across her face. To Frank's satisfaction, most of the expressions were happy ones.When she woke up, she often stretched, with her eyes mostly closed and joints bending with astonishing flexibility. The stretches. " Oh, I didn't say I wouldn't try. I just want to tease him because I know he wants to fuck you. Don't you, honey?" She teased. I knew she was OK with things so far."Well, OK. I do want to fuck her OK. I mean Jerry wants to fuck you and unless I miss my guess you would like to fuck him. If not, then you just like sucking cock a lot." I teased back."Well it does sound like fun. We'll see how the rest of the visit goes. Right now we better get back to camp before it gets dark. We got a hike ahead. It had stirrup like fixtures at one end to place the feet in so the legs are kept wide apart. I placed her feet in the stirrups which were set wide apart, and then moved the fixture towards her hips so that her knees bent towards her chest, and then strapped her knees and feet so that she could not move. She was still deeply asleep and would not wake for some time. I strapped her wrists to posts on each side and behind her head. Then I put the blindfold on her and a strap around her waist to.
