The Silken Family Trap - Part I

She was lying where I had pushed her, propped on her elbows facing me. Her legs were apart and her short white A-line skirt was hiked up to the top of her thighs, her platform high heels swung just off the floor. Her bust heaved with anger and then laughter, straining her breasts against the pink cashmere sweater she was wearing. 
Her legs were encased in the shiny gossamer of taupe pantyhose, I could tell they were the expensive, sheer to waist kind she wore for her best dates. With her sluttish makeup and flaming red hair I could understand why the boys all loved her, she was my sister but I felt my erection start to return just looking at her.

“You aren’t telling anyone about anything” I said. 

“Like fuck I’m not” she laughed back. “Starting with mom. She will be really keen to know her son was dry humping her leg like some dog on heat I’ll bet” 

“You will be lucky if she doesn’t throw you out” she sneered. 

“Oh I don’t think you will” I hissed at her and then I noticed the fear in her face, she knew she had pushed me too far. I knew I was caught dead to rights and the only way I could save myself from a life of blackmail from bitch sister was to make sure I could blackmail her back.

“Yeah, I don’t think you can tell anyone anything about my pantyhose fetish, especially as you are a willing participant” I sneered at my sister. 

“What the fuck are you talking about” she just managed to get out when I fell on her. I pushed my face into hers and mashed my lips against hers. She struggled and I followed the movements of her head to keep my mouth over hers to keep her quiet. She was struggling beneath me but even though she was a well-built girl, I easily outweighed her. I reached down and opened fly and pulled out my cock, it was semi-erect.

Eileen could feel me moving on top of her and when she felt my half-hard cock on her pantyhosed thigh she really began to struggle. I began to harden as I felt the silky feel of my sister’s nyloned thighs rubbing my cock. I didn’t have to move because her struggling was making a nice rocking motion that kept my cock rubbing nicely on her hosed thighs.

My sister wasn’t dumb, she was no virgin and figured out what I was doing and stopped struggling. She pulled her head right back and breathed out softly

“But I’m your sister Mike, I’m your sister!” 

“I know that. You are my cock teasing, slut sister, who lounges around the house showing off her assets just to tease me. If you suspected I had a pantyhose fetish, then you must have done all that on purpose!”

“But I’m still your sister, we can’t” she sobbed. 

“Well I can” I said. 

I reached between us and hiked up her skirt all the way over her hips, I positioned my now rock hard cock between her silky nyloned legs and against the gusset of the nylon panties she wore under her pantyhose. Then I began to move slowly back and forth, pushing my cock against her gossamer encased pussy. She had given up the struggle and was quietly sobbing, her head was resting against mine.

“Don’t Mike, please don’t, I’m your sister” she whispered.

“I don’t care”, I whispered back. “I have wanted to do this for so long, I don’t care about the consequences.” I whimpered and then gently kissed her. 

She didn’t respond at first so I kept up the pressure lightly on her lips until I felt the first stirring’s in her. My cock, which was encased in the folds of her pussy but surrounded by the nylon of her panties and hose, suddenly felt sticky warmth against it. Although I was close, I knew I hadn’t come yet, so it could mean only one thing, my sister was getting wet. 

Oh my God! I got even more excited now and started a rhythmic humping, that forced the head of my cock to push against where I though her clitty might be under the nylon of her hose and panties. I must have been close because I felt my sister squirm slightly and adjust her ass so that my cock moved a fraction to what must have been the right position for her. 

Then I felt my sister start to hump me back, as I pressed my cock against her she pushed back against me. I was in heaven, dry humping my sister like this. I put my hands under her ass and squeezed her buttocks through her sheer hose and nylon panties. It felt wonderful. Then she amazed me! My sister lifted her legs up and rubbed them over my back.

She reached around and pulled my shirt out of my pants and rucked it up my back. I felt her pantyhose legs lock behind my back and rub the sensitive skin there, as she rocked in time with my thrusts. She was now rising up to meet my thrusts and kissing me passionately. 
She was breathing hard and fast. The feel of her pantyhose encased legs rubbing my back, her nylon pantied ass in my hands, her soft lips kissing me, her sheer pantyhosed and nylon panty covered cunt pushing against my cock was exquisite and I felt myself about to release. 

I pushed hard against my sister and felt the end of my cock push the fabric of her pantyhose and panties just inside her cunt. It was too much. I shuddered and felt streams and streams of my semen flood into her and soak the material of her panties and hose. 

She shuddered back and gripped me with her tight nyloned legs and I felt her orgasm rage through her and her cunt spasm against my nylon covered cock.

We held each other that way for a few minutes, then she lay back and dropped her legs. She smiled up at me through her smeared makeup and said “We are in so much trouble now” and giggled.
