Meanwhile Mistress CRYSTAL has stripped FIONA and is using a mains powered vibrator on her clit. ?Did you know Philip that when FIONA orgasms she usua...ly pisses herself because she totally loses control? say CRYSTAL conversationally. FIONA sits on the throne as the vibrations build up and Philip can see her neck redden as precursor to her climax. Mistress turns off the vibrator and teasingly says ?Not yet?. CRYSTAL takes FIONA erect nipples and bites them sharply, and then she sucks them very. Erin rolled off me and sat with the blanket covering her. I moved and stuffed myself back in my jeans. Her eyes were closed. I saw the rise and fall of her chest, I'm sure I was doing much the same though I couldn't tell. My mind was a mix of emotions as it frequently was. Sadness overwhelmed me partly because of the alcohol, but beneath that I was happy if only for a moment. There were doubts too. Does she really want me? How could she love me? Do I deserve to be happy? What's gonna happen. She was falling in love - falling head over heels in love - with Paul. And although my sister and I remained as lovers, I could feel the difference in our couplings. The old frantic need for closeness; the intense demand for acceptance that had once dominated my sister's surrender of her body to my every whim was no longer operational. What sex did occur between us was soon almost casual - incest became almost an incidental part of our sibling relationship.And in a funny way, I was glad.I. Just the short distance from Sydney to here brought a dramatic change in the weather, here it was cold, snow lay on the side of the road and the forecast was for frost and more snow. I was glad I wasn't out in weather like this hitching, for that was what I intended if I never got this job.After watching TV for a bit we turned in, Mum in the bedroom at the back, me on the lower bunk of the other bedroom, if you can call it that.There was one appliance I didn't know was fitted that if switched.
