It was totally a new feeling. Soon the pain turned into pleasure and I started enjoying the fuck. I also started moving my hips in sync with his thrus...s.He increased his speed. I passionately started squeezing his back, his ass and playing with his hair. He was licking my ears, my boobs, my tits. I was just enjoying the moment and moaning. We must be fucking for a good half an hour and both of us were nearing climax. He had spread my leg and placed them on his shoulder for a more deep. I am so tempted to give in and let him, or is it she do me. I feel my pussy get wetter, and my nipples rise to their peaks, when the door opens. My jaw drops, and my eyes bug out.“Sam this is Tim. Tim this is Samantha. Remember I told you about her?”I mumble a greeting while drooling. He stands about six-foot-eight or so. Shoulders wide and square, biceps larger than my thigh, and visible through his spandex suit is a cock that must be at least ten inches, and as thick as my wrist.Sooo…. Jessica," an older nurse called out.I stood up, grabbed my purse, and followed the nurse back to the clinic.It was not all that bad in the beginning. I was asked to place my purseon a table and take off my shoes. My height was measured and then Istepped on a scale to see what I weighed, 120lbs. That was pretty good Ithought for girl of my height and figure. I realized I was againthinking if I had gained any weight since I took over Jessica's body.Why was I so concerned about this? I have got to. I’d been riding on the bus with a bunch of guys going to a track meet. I hadn’t done anything, but my fantasy machine was running in overdrive the whole trip, so when I’d taken my shower, I put one foot up on the toilet seat and whacked off to the fantasy of all those guys. I was wearing a loose summer dress with no underwear so I still smelled like sex when I sat down to dinner. Walter knew my scent and gave me nice looks while we ate. Linda seemed oblivious, but she was always a little.
