Mommy Sits on my Lap part 3

... parted and I could see up her skirt; her slim thighs, encased in the sheer taupe nylons led my eyes to her crotch. She was wearing red satin panties; clearly visible through her sheer-to-the-waist pantyhose, her ample breasts clung to the translucent material of her dress, the matching bra just visible. My cock twinged. "Here; have a drink with me," she offered me the bottle and as she did, her gaze caught mine and she saw where I was looking. "Fucking men! They only have one thing on their fucking mind! I'm your fucking s****r for god sake!" a single tear ran down her cheek, streaking her mascara. "Here Mike have a good look!" She opened her legs wide exposing the V of her panties; the red satin clung to her mound, her cleft clearly delineated by the shiny red satin and gossamer pantyhose gusset. I stared for a beat and then looked away, a little ashamed. "I don't know why you looked away like that; guilt I expect. Guilty because you watched me fuck that guy at the wedding last night; guilty because you watched me masturbate while you hid in the bougainvillea.

"Waste of time that would be; blackmailing a dweeb who spends most his time locked in his room surfing for porn or locked in the bathroom wanking into my underwear." "You're both pathetic!" she was crying but she was also angry. I was quivering with rage and guilt; clenching my fists. "I might as well go upstairs and get changed; now that Tim's not coming. When you wank into my pantyhose later, which you are sure to do, please don't put a runner in them; they're expensive," she jeered. "Fuck you Shelly; you cock teasing slut!" I hissed. "I don't think so b*****r. You'll have to wait for our mother to come home," she giggled, obviously d***k. "You cunt!" I seethed That was the last straw; I leapt on her. My s****r struggled as I lay on top of her but she had been drinking and anyway she was no match for my strength. I managed to get my legs between hers and pried them open and thrust forward so my hard cock was rubbing against her groin. Her skirt had ridden up and my cock, still trapped in my shorts, rubbed against her panty and pantyhose clad mound. I groaned and inhaled her perfume. "Get off me you sick fuck!" she pounded my chest with her fists. I pushed ...
