I had drilled that into Jenny’s head over the past week when I ordered her around like she was a personal slave. It had been fun having a little pup...et on a string. It was not fun being a puppet on a string though. I asked myself why anyone would put themselves through such a constant tease by voluntarily submitting to someone else’s whims. Jenny enjoyed it. I knew she wasn’t just pretending to get on my good side either. When I wasn’t bossing her around, she constantly asked me what she could. Back just a bit and up slightly less. Then back a little more, up a little less. Back and forth, working it inside me, working my way down the well lubricated shaft, feeling it fill me further and further until finally I could feel my rear come into contact with the base of the strap on. It was finally completely inside my ass. I had fulfilled my purpose, my command and completely converged with the other rubberdoll. I got a huge dose of pleasure, one that wrapped around my body making it. To be owned, possessed... to be Your possession... helps me regain my composure and arouses me at the deepest level. My hips again begin rocking with the pulsating vibrations, and I can literally feel my clit engorge with blood, thoroughly aroused by my willingness to completely submit to You, mind, body and soul. Once that decision was made, it took no effort at all to lock my remaining wrist to the floor, with a simple twist over the padlock, the cuff effectively pushed it closed. Now there. My right hand landed innocently enough on her back but my left hand found her left breast. I pulled my hand away as if it had touched a hot stove. "Good lord, you are jumpy aren't you? You needn't be so nervous," Beth said. She turned and stepped out of the pool in front of me and I was treated to an up close view of that spectacular ass. The white areas normally hidden by bikini bottoms were framed by a nice tan. She had very slim hips but her ass was muscular and well rounded. I'm guessing.
