Sister's Jerk (incest, straight, teen sex)

Here2Jerk's sex story
An erotic tale of me and my sister. Caught wanking, and the torture I was forced to endure at her mercy.



My sister Lauren is twenty, short, a little chubby, has long blonde hair and massive K-cup titties. I love staring at them. Tight shirts, her bikini when we go swimming, it all gets me hard as nails. Recently however, I discovered if I climb the tree outside her window before she goes to bed, I can peer in at her 'naked time'.

She strips off her clothes and hangs out in her room for a little while. She just reads, sorts her clothes, and if I'm lucky she masturbates. This is quite the site. Her fingers up her pussy pleasuring herself like no man can, whilst her other hand fondles those great big boobies. I wank myself until cum. Not only when she's masturbating. On all of the nights she strips off, but these are the best.

It was one of these nights that I was getting super excited whilst I massaged my cock, and I fell out of the tree. I put my hands out first for some reason and broke my wrists. It was so embarrassing. Broken wrists. My cock out of my pants. At the bottom of the tree outside her room, where she knew she was masturbating and playing with her big tits.

She knew what I was doing. And the plaster casts would be on for the next four weeks. I had become so accustomed to cumming in my hand, I found humping things around the house didn't help me cum at all. So it would be a long four weeks. I would usually cum four times a day, and now I couldn't at all.

That, and my sister was going to make my life hell. She came into my room late one night, and said 'wanking to me, hey? You're own sister? Well, I am going to get you back.' Looking at her in the tiny teddy she came in dressed in, and hearing her voice had me barring up. And she grabbed my cock, and started pounding it. I could feel myself ready to explode within seconds, and she let go. 'Welcome to your life for the next four weeks.' she said and walked away, leaving me wanting.

She kept touching me when she'd walk past me in the house. Making dirty comments and making me hard. She kept coming in my room whilst I was sleeping and turning porn on on my computer. I would wake up to sexy big tittied chicks wanking and fucking men and would have to go over and struggle to turn it off in my plaster cast.

One day when she was out I went into her room. She has pictures of herself and friends in bikinis on her wall from days they went to the beach. I managed to get my pants off and one of her shoes. I lay on the floor and put my dick in the shoe. I stared at the pictures and fucked. This felt good. Almost as good as my hand. I was going to cum. Finally. After almost four weeks of orgasm torture with not a drop of cum. I was going to cum!

Until the door opened. 'Oh my god!' my sister said. 'I am going to get you so good.'

I lay in bed that night, dreading my torture. I fell asleep after nothing had happened, but I awoke to something that felt amazing on my cock. She was fucking me. Riding me like a cowboy. Jumping up and down. Screaming in orgasm. And then she jumped off. The next few nights were the same. I would awake to fucking, sucking, or tit jobs. My cum was swelling so hard, my balls were enlarged double their size. I was in agony.

Until I got the cast off. I came straight home, and marched right into her room. She was sitting at her desk, working on something. She turned and smiled. 'Hey brother, got that cast off finally?' she said.

I didn't respond. I dropped my pants, pulled her top and bra down and exposed those titties, and then started to wank. I was wanking furiously, like a madman. It felt better than any wank I'd ever had, and I knew the cum was going to be amazing.

'Oh baby! That's it! Keep going! Don't stop!' she begged. I spewed forth my load. It pumped out so hard, I felt in in my guts so strong, almost like I was going to be sick. But not in a bad way. It was amazing! Four weeks of cum load shot out of my cock in five or six massive squirts, and then another load drooled out after that. All covering those massive K-cups and she massaged it in with her hands, and moaned.

'Oh baby! Wasn't that so much better than sneaking around on me? I have needs to your know. You come to me, anytime you want to cum!' Me and my sister live a healthy life of seeing to each others sexual needs from now on, and although it was agony for the most part, I always look back on this experience as one of the greatest times of my life!
