I found myself enjoying it, though not as much as she obviously is. While I’m burying my tongue in her drooling opening I’m able to see Ty order J...e to bend over the arm of the couch and start sucking his cock again.It isn’t quite as shocking the second time. I watched as I worked on my sister’s pussy, curious to see how he really feels about what Ty is making him do.He obviously hates it. He looks furious and repulsed all at the same time. The tears born of helplessness and disgust started. She let out a little scream so I grabbed her mouth pulling her head back again. I had her bent over with my hand over her mouth and my strap-on banging away at her, I reached out grabbed a towel that was close by twisted it up put it in her mouth and pulled the ends as I pushed inside her, I felt her spasm and shake but that just made me go at her more. I was so turned on at this point I could feel how wet I was and her screaming into the towel was certainly getting my knickers wet.I had her. The more I thought about Mandy the hotter I got. I quickly stripped out of my remaining clothes as I sat there in my living room and was soon in fine "masturbation form". I got hornier and hotter the more I thought about all the sexy fuck sessions Mandy and I had shared in the previous two weeks and then I just gave in to the impulse and laid back as I wanked my cock up and down harder and faster until I could feel the unmistakable pressure of my orgasm building and then I continued to stroke. Presently he stopped work and sat down for his morning break he looked at her and said "hello again catching some rays" glancing up at the sun "er yes" she said "arnt you a bit overdressed for sunbathing" he commented with a nice smile "er yes I suppose so" she stammered "I cant wear a bikini in my back garden though can I" she said "why not?" he enquired "its your back garden" then he changed the subject "so how come you are not out with your friends or your boyfriend" he asked starting his.
