My name is Ariana and I am 18 years old. I have long dark hair and dark eyes and nice firm young figure. I have small firm breasts and a flat belly. I go to college and have my fair share of hookups with guys, but nowhere near as much as my step-sister. My step-sister is a right little whore.
Isabel, my step-sister, is twenty-three, and like I said, she is a right little slut. She loves sex and tries to get with the guys as much as possible. I say guys, she is bisexual and goes with everything, girls, guys, she’s even told me that she has been with a crossdresser and a transsexual.
I go to college and have to take the bus home every day. Isabel works locally and has no qualms about bringing strangers home for a one night stand or a quickie. I’ve often come home to see a stranger leaving, like I said she’s a whore.
Mum and dad are hardly around, mum works full time as a secretary for a paralegal and dad is away on business a lot. Mum doesn’t usually get home till about nine in the evening and dad, when he does come home, gets home about eleven. Us girls usually fend for ourselves, but we are fully grown so it’s all fine.
It was an afternoon like every other, I had finished classes in college about three, slightly earlier than usual. I also got a lift home from a friend, making me get home a full hour earlier than I usually do. I opened the door to the sound of my step-sister groaning.
I slowly walked up the stairs, walking passed Isabel’s room, her door was wide open and I could see her having sex with some burly bald guy. I didn’t recognise the guy, but Isabel seemed to be having way too much fun.
The man was fucking her missionary, her legs and arms wrapped around him. She was groaning and whimpering as he really went to town on her. He slammed hard, making her voice jump with each thrust. I know it was my step-sister but I couldn’t look away. It was mesmerising.
I absent-mindedly slid my hand over my chest, caressing my breasts over my clothes. It was so hot watching them, the thought that they didn’t know I was there was fun too. I slowly undressed, stripping off so I was completely naked.
I slid my fingers over my slit, I was already quite wet.
It wasn’t long before my fingers had slipped deep inside my pussy as they had changed positions. He was fucking her from behind, doggy style. His hands on hips pounding her for all he was worth. I could hear the headboard of the bed banging against the wall.
It was so hot watching my step-sister getting fucked, I could tell how much she loved it too. He seemed to push her forward with every thrust, making her get closer and closer to the wall. Soon she had her hands up against the wall as he fucked her from behind.
By then I had two fingers stuck deep inside my pussy, my other hand squeezing my breasts. I could not take my eyes off them, as my step-sister seemed to orgasm. Her body shook, pushing her man back off her pussy. I watched in amazement as my step-sister gushed all over the bed, making a wet mess.
Isabel climbed off the bed as the man lay back on the bed, I could see his cock was quite impressive, even if he wasn’t. I studied him closely, he was in his late forties, fat and bald. I guess Isabel just liked him for his cock, he was not a looker.
Isabel climbed back on top of her lover, straddling his lap and impaling herself on him. She leant forward, resting her hands on his chest. I watched as she slowly bounced on his cock and I could see it sliding in and out of her as she bounced on him. She had to nearly stand and slide back down his cock was so big.
I could feel my legs start to shake and my face get flushed, I knew the feeling all too well. My orgasm rippled through my body, making my toes get pins and needles. I covered my mouth to stop myself groaning. I could just about make out Isabel jumping off her guy’s lap as he shot his load over her butt.
I picked up my clothes and sneaked into my room. I locked my door and lay back on my bed panting. Fuck, my step-sister was a real whore, but she sure could fuck. I giggled to myself and drifted off into a comfortable sleep.
