Horny with My Sisters Husband

I'm having a horny affair with my sisters husband. I never meant it to happen but every time I think about him I get so horny. Every day I have been playing with myself while thinking about him. It's so hot I can't stop myself.

Right now I'm lying in bed naked rubbing my hands all over my thick curvy body, squeezing my big round bum. My long brown hair sprawled across the pillow as my hands caress my large juicy tits while playing with my nipple ring. I slowly stroke my hands down my body until I reach my soaking wet pussy. I gently start to massage my clit as I think about my sisters husband.

It all started 3 weeks ago when I went up to visit my sister at her house, I normally visit at least every Friday for a catch up. I walked in and called her name but no answer, I then called his name and still no answer. I decided to look about the house and as I made my way up the stairs I could hear light grunts coming from the bedroom, curious I called out hello and opened the door. Standing naked facing me was my sister husband Allan. He was standing 6ft tall with broad muscle shoulders and thick rugby playing thighs covered in tattoos and holding his thick 5inch cock. I got a shock and let out an "oh sorry" but somehow I was frozen to the spot, unable to leave and turned on by the sight of him in front of me. He still had his cock in his hand and with me unable to move watching him, it must have been too much and he suddenly came all over the floor.

I heard my sister come home and I suddenly snapped back to life and hurriedly shut the door and ran down stairs. As I sat in the living room sharing a drink with my sister, I couldn't help but think of her husband upstairs and how good he looked naked. I was so turned on and wet thinking about him so I made my excuses to leave early and went home. As soon as I got home I stripped off naked and jumped into bed and put my fingers to work, it was the fastest I have ever came.

Every morning when I woke up and every night before I went to bed I would masturbate thinking of my sisters husband. I would lie in bed soaking wet with my thick dildo pushing it in and out while moaning his name. I would squeeze boobs hard and finger my pussy wishing it was his hands instead. I would run my vibrator up and down my clit thinking of him standing over me with his thick cock in his hand.

Finally it was Friday again and I just could not wait to see him. But what are the chances of me catching him again? I decided to go up a little earlier than usual as I knew my sister wouldn't be home yet. I walked into the house and he was nowhere to be seen. I got so excited walking up the stairs, hoping I would find him wanking off again. I called out his name and opened the bedroom door and to my disappointment he was standing their in his work clothes and hi vis vest. He still looked good but couldn't help but feel sad.

He then walked towards me and lightly grabbed my shoulders and sat me on the bed, all without saying a word. He then started to undress and I got so excited. He pulled out his hard cock and started stroking it right in front of me. I couldn't take my eyes off him or his hard cock. It was so sexy and I was getting so turned watching him. He just stared right at me as he was wanking off. He moved closer towards me and his cock was right in front of me. I couldn't resist and reached out and grabbed his cock and slowly brought it towards my lips and started sucking him off. I felt so good in my mouth and I could hear him start to groan as I took his cock deeper in my mouth. He could no longer handle it and shot his load down the back of my throat as I swallowed every last drop and licked my lips clean. I left the room feeling hornier than ever.

The next day I get a text from my sister to say Allan was on his way down to drop off my shoes that she borrowed the week before. I started to think maybe this time I will give him a show.

I rushed up stairs and took of my clothes and lay in my bed wearing nothing but a lacy black bra and matching thongs. I was already so horny. I started to massage my pussy over my underwear and could feel my wetness through them. I then heard the door go and heard Allan call out my name. I could hear him coming up the stairs and the closer he got the more excited I felt. I started fingering my pussy as soon as he entered the room. He didn't know where to look, he took his time eyeing up my full body and I could see the lust for me on his face. He took out his cock which was already raging hard and started stroking it fast. The faster he stroked the harder I fingered my pussy while we both just watched each other. It was so hot. Suddenly he moved forward and pulled my bra down and roughly squeezed my boobs before going back to stroking his cock. I could tell he was close to cumming with the sexy grunts he was making, when he aims his cock and shoots his cum all over my big juicy tits. He then walks down to the bottom of the bed and gently pulls off my thongs and puts his head in between my thighs. He uses his tongue to push around my clit and pushes two fingers inside fucking me hard. The feeling is amazing and I can feel my orgasm build up and it doesn't take long for my legs to start trembling. I feel this hotness come over me and I start screaming out in pleasure as I cum right on his tongue. He licks up all my juices before standing up and zipping his trousers back up. He tells me how hot and amazing that was and then he leaves. I lay there naked covered in cum thinking how wrong that was but also how sexy and hot it made me feel and how I couldn't wait to see him again.

Friday rolls around again which was last week and I couldn't wait to see what was going to happen. I walked up to my sisters wearing a tight black vest top, mini denim skirt and black ankle boots and no underwear. I couldn't wait to tease him. The three of us sat at the dining room table drinking cocktails and playing cards. Every so often I would reach out under the table and stroke his thick thighs or gently squeeze his hard cock over his trousers. Every time my sister left the room I would flash him or make an excuse to bend over right in front him knowing he wouldn't be able to resist squeezing my bum. He would grab my tits or quickly shove a finger in my pussy whenever she wasn't looking.

It was coming to the end of the night and my pussy was dripping wet. My sister went to make the last batch of frozen daiquiris. I took this opportunity to bend over right in front of him and start fingering my pussy. He immediately stood and grabbed me and pushed me over the table. I was shocked at how rough he was and I thought he was mad at me teasing him until I heard him unzip his trousers. He got his cock out and roughly shoved it in my pussy and started pounding me hard. He grabbed my boobs while fucking me and I had to bite my lip to stop myself screaming out in pleasure. He thrust into me harder and harder while whispering in my ear that I'm a tease and a horny little slut and how hot he finds me. The fact I know we could both get caught at any point made the whole thing so much more thrilling. I could feel myself start to cum and let out a moan. He put his hand over my mouth and fucked me harder shooting his load up my pussy as my whole body started shaking from my own orgasm.

He quickly zipped up his trousers as we could hear my sister coming back through with the drinks. I then fixed my top and skirt before sitting back down at the table. I enjoyed my last drink with my sister and her husband as I sat there with his hot cum still inside me dripping down my legs.

I have never felt so horny and turned on in my life. I can't wait to find out what will happen next Friday...
