“What are you doing?” asked my sister.
“I just want to see what it feels like,” I replied.
“What?” she asked.
“I was just wondering what your slip feels like,” I said, as I continued to rub my hands up and down her slinky satin-slip. I was somewhat surprised that Kelly didn’t try and stop me or object. I moved to her side so I could watch her as I moved my right hand down over her bum and stroked the lovely satin-slip, feeling it slide effortlessly over her silky satin knickers. My left hand slid up and down her stomach with my thumb just brushing the underside of her shapely and firm breasts. My sister stood motionless, looking me in the eyes, biting her bottom lip, her right arm outstretched with the paintbrush touching the wall but not moving.
“So you didn’t answer my question,” I said.
“What question?” asked Kelly with a slight quiver in her voice.
“Do you feel sexy now, wearing that lovely silky slip?”
Kelly looked me straight in the eyes. Without even blinking, she answered, “Yes, I do.”
“I love the way your slip feels over your satin knickers,” I told my sister as I continued to feel her buttocks. “Think how nice a satin blouse or a satin dress would be over the top of your slip, satin upon satin. You would feel the layers of satin sliding over each other as you moved.
Imagine the admiring looks you would get from people if you wore a satin dress to go grocery shopping,” I said. Kelly laughed at the idea. “I’m serious. You have no idea how much attention you would attract from men and other women. You should wear satin every day, even if just a simple shirt-style satin blouse with a pair of denim jeans. Maybe a pencil skirt with a long slit at the rear, with your satin-slip showing underneath as you walk along the road.” Kelly chuckled once more.
“Are you serious?…. Are you telling me you notice such things as a woman’s slip under her skirt when she walks?” asked Kelly.
“Hey sis, I can spot a woman wearing satin from half a mile away, even if it’s just the collar of her blouse peeking from beneath her coat. It drives me crazy. Honestly!” I told her seriously.
As I continued to fondle my sister’s buttocks with my right hand, I moved my left hand higher over her breasts, gently brushing over her nipples as I did so. Kelly took a deep breath as my hand glided over her breasts and brushed her sensitive nipples. She closed her eyes and tilted her head back slightly, letting out a gentle sigh as I continued to feel her tits through her satin-slip. I cupped my hand over each breast in turn and gave it a gentle squeeze. My sister’s tits were amazing, perfectly formed and very firm, despite having given birth to Amy. Kelly made no attempt to stop me playing with her tits, the pleasure she was getting from it was obvious. Her nipples grew hard and protruded further out through the thin slinky material of her satin-slip. I pinched each nipple through her slip and gave it a tweak. I moved back around behind her, fondling my sister’s breasts with one hand, whilst sliding the other hand down her body and between her legs. My right hand continued to squeeze and fondle Kelly’s tits whilst my left hand cupped her pussy. I rubbed my left hand up and down Kelly’s silky slip between her legs, feeling the satin-slip slide over her satin panties. Kelly dropped the paintbrush. Her body went limp like a rag-doll, her legs buckling beneath her. If I hadn’t held her up, she would have collapsed onto the floor. Kelly made audible moans of pleasure as I tweaked her nipples and rubbed her slip over her pussy. The pleasure she was getting was obvious and she made no attempt to stop me. I was determined to see how far Kelly would let me go before stopping me or saying no.
“You said Eddie wouldn’t be back for a while?” I asked.
“Not for… at least… two… maybe… three hours,” replied Kelly, panting with deep breathes.
I picked up my sister’s limp body in my arms and carried her into the lounge, placing her on the sofa on her back. As she lay there looking more attractive than ever in that lovely black satin slip, Kelly surprised me by pulling her slip up around her waist to expose her bright red satin panties, as if she was inviting me to explore.
“Oh wow!…” I exclaimed.
I noticed a small damp patch and could make out the slit of my sister’s pussy through the tight silky material. I spread my sister’s legs wide apart and knelt on the floor in-between. I placed the tip of my index finger on my sister’s silky soft satin knickers and rubbed it up and down her slit. Kelly immediately shut her eyes and let out a gentle moan, taking deep breaths. Her breasts were heaving. Watching my sister as I stimulated her pussy turned me on. The tight satin material felt great against my cheeks as I rubbed my face over my sister’s soft silky panties. I pushed my nose into the damp patch and rubbed it up and down her pussy slit. The pungent smell hit me like a slap in the face, but being aroused at what I was doing to my sister, I didn’t care.
“Oh, fuck!…. I can’t believe this is happening,” moaned Kelly.
I couldn’t believe it was happening either, but until my sister said no or tried to stop me, I wasn’t about to stop. Kelly was writhing on the sofa, squeezing her own tits through her satin slip. I hooked two fingers under Kelly’s satin panties and pulled them to one side. I was somewhat surprised that my sister was completely shaven and admired her moist pussy slit. It wasn’t at all how I expected it to look. A friend told me he didn’t like going down on his girlfriend. He said it looked like a bomb had gone off down there. I remember thinking to myself, “What a crude de***********ion!” Having seen pictures in magazines, I understood what he meant. In comparison, my sister’s pussy was one of the nicest I had seen. Having sucked my fingers to wet them, I explored my sister’s pussy more closely.
I buried my face between her legs and pushed my tongue as deep as I could into my sister’s snatch, licking and sucking as vigorously as I could. I flicked Kelly’s clitoris with my tongue, sucking it hard, making her scream with pleasure, her whole body writhing about and shuddering as she orgasmed.
I was so aroused my cock was rock hard and twitching in my pants. I just had to relieve myself somehow. Either my sister would have to let me fuck her, or I was about to rape her. I pushed off my shoes, then stood up and quickly removed my jeans and pants whilst Kelly just lay back on the sofa and watched with a shocked look on her face. I stood there momentarily in just my shirt, with my eight-inch erection, waiting for some glimmer of response from my sister. Kelly stared at my cock with a slightly worried look, knowing what was about to happen. Unsure if she should try or even wanted to stop me. I reached down and removed those gorgeous bright red satin panties Kelly was wearing, then lifted them to my face to sniff them. After discarding the panties, I grabbed Kelly by her ankles and pulled her onto the lounge floor onto her back. Kelly hit the floor with a thud, banging her head.
“Ouch!… Careful!” cried Kelly, rubbing the back of her head.
I knelt on the floor and spread her legs open, placing them over my shoulders, pushing all my body weight down onto her. My erect cock found the opening of my sister’s sopping wet pussy without any need to guide it into position. Within seconds I was buried deep within my own sister’s pussy and thrusting my cock in and out as hard and as fast as I could, giving it the pounding of her life. My only consideration at that moment was for my own selfish pleasure. I couldn’t have cared less if I hurt my sister or not, as I pounded her pussy with all my might. I began to sweat heavily. My shirt clung to my damp body; drips fell from my forehead onto my sister’s face as I looked down on her. I pumped my cock in and out continuously, watching her breasts bounce back and forth under that rippling black satin slip. Kelly screamed with each inward stroke of my cock. Her face contorted as if in pain.
“Don’t cum inside me!… Don’t cum inside me!… Please don’t cum inside me!” she begged, over and over.
I ignored my sister’s pleas. I had no intention of withdrawing from my sister’s pussy until I had discharged my load of cum. Suddenly, my whole body shook. An intense feeling I can only describe as a-mild-electric-shock ran through my hips and thighs. I grunted and pushed my cock deep inside my sister’s cunt, as I ejaculated inside of her, filling her womb with my fertile sperm.
As I got dressed, Kelly lay on the floor in the lounge and started to cry. “Oh my God!… Oh my God!… Oh my God!” she said over and over. “What the hell have we done?”
A sudden rush of guilt hit me. I felt totally ashamed of myself. I sat down on the sofa and stared at my sister, still crying on the floor. I started to tremble uncontrollably. Panic was setting in at the realisation of what I had just done. Neither of us spoke for what seemed like an eternity. After probably just a few minutes, my sister got up off the floor.
“I’m going for a bath,” she said in a soft, hardly audible tone. I sat there gathering my thoughts, trying to fathom what had just happened and why? After about thirty minutes, my sister reappeared dressed in jogging pants and a baggy sweatshirt. She had made us both coffee and handed me a mug.
“Thanks!” I said, watching her as she sat down opposite in an armchair. She sat staring at the floor, avoiding any eye contact with me. Nothing was said as I sat drinking my coffee. I kept looking at my sister, wanting to do or say something to put things right, but she remained staring at the floor the whole time, deep in thought, avoiding any eye contact.
Eddie was due back with Amy soon. I didn’t want to be around when they arrived home. I stood up and said goodbye to my sister, but she didn’t reply. Her red satin panties were still on the lounge floor exactly where I had discarded them. Imagine Eddie arriving home with Amy, walking into the lounge, seeing Kelly’s red satin panties on the floor in the middle of the room. Why?… How would she explain that?… I picked them up, watching my sister. She didn’t move or take any notice as if she were in a trance. I put the red satin panties in my pocket and left the room.
