Mistress moans quietly as she traces the outside of her vagina. Teasing herself before dipping one finger in between the folds and massaging her clit....Ashley can only look on in shock. 'What is happening? Why is this woman pleasuring herself to the sight of me in a cage?' Ashley squirms a little, trying to get comfortable, but Mistress has cuffed her so this is impossible. She can barely move. Mistress sucks on two fingers on her other hand and then slowly slides the moistened fingers into her. "Open your legs .... Lena you know you want to, and I'm going to have you right here," I whispered again and resumed kissing her wildly whilst my dripping fingers were making her moan and respond. I took my cock out in relief from the confines of my trousers, and place her hand on it."Its bigger than I remember" she smiled, "but I hadn't actually held it before now!" I haven't actually fucked you either until now," I replied.She took my trousers off and lowered my pants. I wanted to face fuck. I think I felt something like butterflies with the realization of what was about to happen. The best way to describe the sensation was that I suddenly felt flush and like I was tingling with electricity. To start I rolled on my side and took out my cock. Han slid over and took my cock in her mouth and right away I began to piss. My cock got hard pretty fast in her mouth and it's actually not that easy to piss or to control your stream with a hard on. It kind of comes out like prolonged. I admitted that we were not biologically related and that we “expanded” our sibling love to include much more affection than is normally appropriate. Shelly was “weirded out” to use her term, but thought she could handle it. But then I had to open my big mouth and bring up Cindy’s assumed role as my servant. And that did not go over so well. I wasn’t able to explain it, Cindy didn’t care what Shelly thought, and Shelly thought we were beyond perverted and just wanted to get away from.
