"Hi Steve, how was the run" she said."Oh fine thanks Trish, just done my usual 10k....I'm ready for a shower" Ray's off to Manchester now so I'm alone...this weekend, I might see you later" with that she smiled and went inside.She was so attractive and I was constantly thinking about the previous weekend, it seemed I had a constant hard on at the thought of it.I had my shower then had some breakfast. It was now 11am and I had to do some shopping.I got back at 1pm and went upstairs to get changed. I took the nub between my thumb and forefinger and gently pinched it, causing her to jump reflexively. I slapped her ass. “Hold still,” I quietly admonished, then resumed my manipulation of her pleasure pea. She did her best, but could not keep from undulating her pelvic area as I brought her to a quick orgasm. As she lay panting across my lap, I once again wetted my fingers in her sopping quim. But this time, instead of just running my fingers up her cleft, I pushed my middle finger up her. I was with my clothes on.after a few minutes RAul told me taht we should masturbate,what is the problem?so he got his pants off,his cock wasn't hard and strated to rub his cock.i looked at the movie again and i said:why not?so i put my pants down and my cock was alrady hard and started to jark off.Raul then put a porn clip with blond giving a blowjob:"you know if you want i can jark you off"i was in shock:"what?" listen you look at the clip and i will jark you off" no,what are you gay?" no,but. Mary laughed and told me because she had shaved them before and yes, I have also had sex with them. I guess I looked a little surprised when ask YOUR OUN SISTER. She looked at me and said YES, MY SISTER. You, who is laying here in bed with your ass still tender from getting fucked with a strap-on. You, who still has the taste of his own cum and his throat is sore from a deep throat with a toy cock and you, who fantasizes about fucking your own sister while you are having sex with a woman.
