I backed my cock out slowly, all the way to the tip, then sunk it in again just as slowly. After I'd repeated this slow, smooth thrusting several time..., I begin to quicken the pace. I leaned back behind her and grabbed her hips with both hands, guiding her motions as I begin thrusting in and out of her quicker and quicker. Lynne swirled her hips in a circular motion with my thrusts, meeting my rhythm stroke for stroke. The sensation felt amazing, our bodies in sync and working perfectly. The movie is really getting going and so am I, so much so that I hadn't noticed that my sister Susan and her friend Kate had returned home unexpectedly until they were in the room. "Alan!" she shrieks, jolted back to reality I quickly cover up, Kate has her hand over her mouth hiding a giggle, "that's disgusting" Susan yells, I suppose it was to a s*******n year old girl."I don't know" said Kate "looks like fun", and with that sat down on the couch next to me, lifted her skirt, pulled her. She moaned quietly as she fingered herself - she'd never been able to stop herself making noise during sexual pleasure, and had always been embarassed about how slutty she sounded when she moaned like that, but it was easy to not care too much when her cunt felt this good.It was only after she’d cum that she remembered the camera in the corner of the room watching her. Claire was mortified. She’d just fingered herself like a slut on camera. Who had been watching her? Michael? Some nameless. Meantime, I wanted a quick update on how things are going here," said Ben."You should be able to have your crew in about two weeks. They're good, very good. We've managed to shave two weeks off of the time it took to train the Wodenites. The other group will be ready about two or three weeks after that," advised Beckie.Ben shook his head. It looked as if things were going to be very tight and it would be touch and go whether they were able to make it back to Woden before Captain Marlon arrived.
