I need you. Let me into you." I part my legs obediently and again I am taken away from myself. He demands this of me. Always, I give him all of myself... "look at me" His raspy whisper implores. I look at him deep into his eyes. My consciousness a pinpoint focused on him. He moves into me and I gasp. Crying out, calling for him. He lowers his mouth quenching my cries with his hungry lips holding me entranced. Moving as one sinuous, undulating body we rock together slowly, slowly until his need. Finally some self-restraint kicked in and I stopped myself for fear of waking her. I wanted to jack myself off right then and there and get the hell out of the room before she woke up, but I had to see more. With another hungry glance at her tits, I moved back down to my sister's panties. These would be much more of a challenge. I grabbed the waistband on either side of her hips and began to tug them downwards. Suddenly my sister moved! Without warning she rolled away from me, onto her side. As. I didn’t know if she had been aware of the marks on her breasts, so I rubbed my fingers over her areolas and nipples, and said, “I’m sorry, honey, it looks like I got so excited sucking your tits, and I’ve given you a few hickeys. At least they’re just for you and me to look at anyway.”I could tell by the brief, frantic look on her face that she hadn’t noticed the hickeys, but then there was a sense of relief that I was taking responsibility for them. After our shower, I told Wendy that I was. We finally actually met for a drink. She was an attractive lady of about 40 and was pleasant to be with. But, when I again brought up the subject of playing with bondage, she again stated that she was vanilla and that she didn’t want to even try bondage. I finally decided that she wasn’t going to warm up to the idea of being tied up and started to communicate less frequently with her. I am sure she felt my lessening interest in her. Finally, she brought up the subject of bondage play.
