My sister Kristy wasn't expecting me for another hour, I caught an early bus just to get out of the house. My mom has been driving me crazy lately so Kristy has been kind enough to invite me over to stay at her place. I’m 15 and my sister is a college girl, all of 19 years old but Dad set her up in her own rental home across town from home.
There was no answer to my knocking, and as always before, I let myself in, thinking she must be asleep still. I walked quietly through the house, glancing around, but went straight to Kristy’s bedroom. I expected to see her buried under the covers, sleeping soundly, but she wasn't there. The sound of water came to my ears from another room. It shut off suddenly, and I was struck with anxiety. I heard her footsteps as she padded down the hall. I turned and slipped into the closet, sliding the wooden door shut in front of my face. I peeked out through the wooden slats and saw my sister come into her room, naked and toweling her hair dry.
Kristy ran the towel over her face and then lower, drying the rest of her body slowly, as if she enjoyed the feel of the rough terrycloth against her soft skin. Kristy has an amazing body and I couldn’t help but blush with admiration taking it in. My sister’s movements were languid and drawn out, bending over to dry her legs and feet, she gave me a full view of her round ass, and her thick labia between her thighs. She came toward the closet and I shrank back, holding my breath, but she only hung the towel on a hook on the wall beside the closet door. She moved graciously onto the bed, lying down on her stomach and stretching her arms and legs. She sighed deeply and relaxed, spreading her thighs open and drawing her knees up slightly. She folded her arms beneath her head, breathing deeply, rhythmically, her chest rising and falling slowly.
From this angle I could see quite clearly between Kristy’s shapely thighs, and my breath caught as I saw how swollen her lips were. A light glaze of her juices coated her lips, slowly dribbling down to her clit. She began to grind her hips downward, into the mattress, letting out a low moan of pleasure.
I knew Kristy was sexy but this was amazing. I felt bad watching her like this but I couldn’t tear my eyes away. She rolled over onto her back, keeping her legs spread wide, so that I could see her clit which seemed pink and engorged and I noticed the muscles in her inner thighs quivered slightly.
Kristy ran her hands over her full breasts, massaging them roughly, her hands squeezing firmly the delicate flesh, stopping every few minutes to pinch and roll her nipples between her forefingers and thumbs. She arched her back up, her eyes closed, licking her lips as she stimulated her beautiful breasts. She was clearly enjoying herself immensely. And my heart was beating like crazy to see my own sister playing with herself in such a sexy way.
I bit my lip, trying to keep silent as I watched, lest my big sister hear me and be angry that I was in there, embarrassed that she was giving me such an intimate show. I was very aroused, my own little nipples hard, my pussy wet, and I realized I was aching to touch herm my own hot fucking sister. I put the heel of my right hand against my clit over my tight jean shorts and began grinding down on it,
Kristy continued on, oblivious to my frustration in the closet, running her hands down her soft belly, caressing her lovely skin, tracing circles around her bellybutton with her fingertips. I kept my face pressed to the wooden slats of the door, watching intently as Kristy rubbed and squeezed her inner thighs. She moaned again, this time louder.
My sister was so wet that her pussy was pouring a flow of her sweet honey down her ass and soaking the sheets underneath her. She slid her fingers up and down her slit, then spread her lips further open, rubbing the tip of her throbbing clit with her finger and gasping, her hips jerking up. I was shaking with desire, my mouth watering as my sister dipped her finger inside her hot cunt. When she withdrew her finger it was dripping with her juices. She ran her wet finger around her hard clit in small circles, teasing herself. Kristy slid her fingers back down, and this time penetrated her pussy with two fingers. Again, she drew her dripping fingers up to her clit.
She placed her middle finger on one side of her clit, her ring finger on the other, and gently pinched her clit between them, rubbing in slow circles. She took her other hand and plunged three fingers deep her wet cunt making slurping sounds as she whimpered with pleasure. My sister moved at a steady pace, rubbing her clit and pumping her fingers in and out of her slick cunt. I was fighting myself now, holding myself back, feeling as if I would lose my mind, listening to the wet sounds her fingers made, her moaning and groaning, and watching my hot sister bring her self to the brink of an amazing climax. I felt like a caged animal, and every muscle in my body was bunched and tight, ready to spring.
Kristy moaned louder now, her fingers pumping faster and harder, deeper inside her juicy cunt. It was so hot how my sister rubbed her clit in quick little circles, pinching her clit tightly between her fingers and pulling on it. She jerked her hips up now with every thrust of her fingers, whining and grunting. The sound of her wet pussy slurping as she jammed them in and out sent me over the edge, and I fell to my knees, biting back a yell as I came in my jeans. My eyes were still glued to my sister fucking herself hard and fast.
A moment later Kristy let out a sharp cry, her hips bucked violently, rubbing her clit furiously as she exploded in orgasm. The muscles in her thighs were twitching spasmodically as her juices squirted in a torrent out of her convulsing cunt around her fingers. Her hips were frozen up in the air, as a second volley of cum sprayed all over her tense body her fingers still pressed hard against her clit, her fingers still buried deep inside.
Kristy’s body slowly relaxed, her ass dropping back down onto the bed and her breathing returning to normal. She laid there catching her breath, wiggling her fingers inside herself still. Then she leaned up on her elbows, looked at the closet door, and lifted her fingers to her mouth, licking them clean. She smiled as she did this, and I realized she knew I was there. She'd known the whole time. She lowered her fingers back down to her pussy, soaking them again, and licked them clean once more.
Her voice was husky when she spoke. " Hey sis, did you like the show? Now it’s your turn to show me your hot body!"
