A day with my step sister

100% fiction!

My step sister never lived with me except for a short year while I was still only 18. I took advantage of that whole year sneaking into her room when I was home alone and masturbating to her cumsoaked panties and her huge bras. Everyone knew she was a slut and I wanted to get in on that action too. Then she moved away for a few years to live with her mom (my mom is married to her dad).

It all started a few weeks after my birthday. We had a party at our house and she was going to stay for the whole weekend. I thought to myself "this is my one and only shot" so I went in for the kill. I wasn't a virgin but my first time was not very fun. It was a year or so back with a girl who was a virgin and neither of us really enjoyed it.

So one night around 2am everyone else in the house was asleep except for me, or so I believed. I was watching some softcore cable tv porn when suddenly I heard a knock on the door. I quickly changed the channel, hid my boner under the sheets and told the person to come in. It was my step sister and damn she looked great! She was wearing a tight tank top that showed of her beautiful plump c-cup breasts and cute shorts. Thankfully I had quickly changed the channel to discovery as she quickly proped herself on her stomach infront of me asking what the show was about. I said I wasn't paying much attention but I was texting instead more.

She took the excuse and just watched the tv. After about 5 minutes she looked back to me and said that she was really tense and wanted to know if I could give her a massage. I thought about it and decided I was going to go all in tonight. I agreed and sat up behind her slowly massaging her upper back and neck. Im pretty well known for my massages so she says to do a full back massage. She is still wearing all her clothes and I only dare go up until an inch under her shirt. She starts to really get into it and lets out a slight moan. It was so sultry and caused my dick to stiffen just a little bit, enough to be slightly visible through my shorts.

Slowly I pull her shirt up so I can see her full back and her bra strap. I take it nice and slow just incase she doesnt want to do it, you never know! After about another five minutes im starting to massage her legs too, getting up to her ass and giving it a slight squeeze and backing off. Ive drempt about her plump ass that she shows off oh so well. Then she slowly reaches back and undos her bra strap saying it was getting in the way. My dreams have been answered! I move up a bit so my dick fits nicely in her ass crack and she tenses a bit but then settles back down. I massage her sides but reach down under and cup her beautiful plump breasts.

They are so warm I feel like I am in heaven. My dick is as hard as a rock right now and she can without a doubt feel it. She stops and looks back and says to me "I know what youre doing" I freeze and just stare at her not knowing what to say. then she pushes me off her and climbs over me, teasing me with her pussy rubbing up against my dick. Then she starts to move down and pulls my shorts down with her. My dick flings out and nearly hits her in the face and she is surprised that her little step bro has such a thick cock. She stares at it in amazement for a few seconds then goes to work. I can tell she is a pro the way she works my dick.

She strokes while sucking and gets the tongue in my slit. Im in heaven! Ive never had such an amazing blowjob before in my life! Then all of a sudden she stops, does up her bra and walks to her room giving me a cheeky smile as she leaves. Im stunned and then follow my dick right after her into her room. I throw her down onto her bed and rip those tight shorts off her. Then without thinking I thrust my dick into her tight pussy. She tries to stay quiet and lets out a feint sigh of enjoyment. We keep going for another half an hour just fucking till we can't anymore. Shes riding me in all different positions and finally I pull out and burst all over her chest and stomach.

She looks up and licks some cum off her fingers and giggles. She then pushes me away and says goodnight little brother. Ever since then I have fucked my step sister at least twice a month and it gets better every time!
