I couldn't quite believe my luck when my sister, Sarah, came to see that Saturday morning and initiated a steamy fuck where she rode me senseless as I woke-up. We'd had three really hot fucks before that, but I'd initiated them and persuaded her each previous time. Now I was sure she wanted it as much as me.
Sarah is a really hot woman, she looks a bit like the adult actress Ella Hughes, and her pussy felt amazing when I was buried balls deep inside it. I'd fucked around a bit at university and since my return but most of the girls in town wanted a long-term relationship and I didn't. I couldn't believe my luck that my pregnant sister turned out to be as horny as me: we could have hot sex without worrying about a relationship and she knew she wouldn't get a reputation as a slut or anything because I was risking prison if I told people about it.
After that Saturday, we became a bit addicted to sex, wanting and needing to getting each other off. The very next morning, in fact, I woke-up with morning glory. I could hear my parents downstairs but we usually both slept in a bit later than them at weekends so knew we wouldn't be expected downstairs for a while. I got out of bed and gently walked to my door, checked the coast was clear, and then went across the landing to her room. I opened her door and walked in. She was still asleep. Time for the tables to be turned.
I was feeling confident, so I slid my boxers off and walked over to her bed. She was lying on her side with her eyes closed and breathing heavily. I lifted the duvet and slid in under it next to her. She was wearing a nightie. I pressed my body against hers in the spooning position. I reached my arm across her body and slid my hand up her thighs. She began to stir a bit but wasn't yet properly awake. I slowly worked my hand to her crotch and was delighted to find she wasn't wearing any panties under her nightie. It didn't take long before I was tracing my index finger up her slit to her clitoris.
It didn't take long for her to stir after that. "Mmm, what's going on?" she asked, unsurprisingly.
I didn't move my hand at all, but lent forward slightly so my mouth was right next to her ear. "Morning sleepyhead, I woke up thinking about you. Were you having sweat dreams?"
"I was just dreaming some hunk of a man was helping me with my insane horn," she replied.
"Sometimes dreams do come true, sis," I whispered back as I worked my index finger between her pussy lips. She was quickly getting wet and feeling her arousal made my dick completely hard. It was digging into her back. "We probably don't have too long though, Mum and Dad are downstairs having breakfast."
She sighed contentedly and shuffled her body back against mine. I was in no mood to hesitate and pushed legs apart a bit with my hand, then pushed my cock along her dripping slit. "Mmm, I need that hard brother dick inside me again," she said.
"Beg for it," I replied.
"Please big brother."
"Please, what?"
"Please slide your beautiful, hard, big brother cock into my little wet sister pussy again. It feels just right in there," she whimpered. Teasing her more would have been fun, but I couldn't help myself, I needed to be inside her again. Christ, she had the most perfect little pussy and it was like a warm glove gripping my dick as I slowly pushed all the way into her.
I reached up and took her nightie straps off her shoulders, pushing it down to reveal her full breasts and massaged them as I started working my cock in and out of her grasping cunt from our side-by-side spooning position. I soon worked up to a good pace, and loved feeling her body pressed right back into me like this. She was matching my thrusts, bouncing a bit on my dick, her hungry pussy wanting more each time I withdrew.
I moved my mouth close to her ear again. "Mmm, little sister is enjoying this, I can feel it," I whispered.
"Oh yeah, I fucking love your dick so deep inside me brother, mmmm we need to fuck like this a lot, I just can't get enough of this, oh, I'm addicted to your dick Aiden." She started moaning more and I thought about our parents being just downstairs. The risk was fun but I didn't actually want to get caught so I moved my hand over her mouth.
"Mum and Dad are downstairs, we need to be quiet Sarah," I told her, while never missing a beat with my dick stroking in and out of her. We had a good pace going now, and neither of us were in a mood to hang about. I started fucking her hard and needed to cum.
"Mum and Dad have no idea their darling little girl is upstairs taking her brother's dick like this, and she's about to get her pussy filled with his incestual load," I told her. I felt her pussy actually tighten round my cock at those words. She fucking loved the dirty talk. "That's it, I'm going to spray my load right inside you Sarah."
