My step sister had a small party at home for her 18th. Just a few of her friends about 8 in total mostly girls. They were meant to go out on the town after but she drank too quickly and decided against it. I had an early start at work the next morning so I drank sparingly. An old hook up was at the party and I spent alot of my evening dancing with her which led to the usual kissing and touching. But as I didn't want to go clubbing our evenings went their separate ways. I decided to call it a night. My uncle and his wife had already gone up to bed so I wasn't the first but the place was crowded so it meant people were having to share rooms and spaces. My uncle and his wife were crashed out on the bed, as expected, leaving me the floor. I had to share with my step sister and her friend but there was plenty of room left so figured it wouldn't be a problem.

As I'm quietly getting undressed the door opened and in came Sasha, I'm in my boxers but don't care as I play a lot of sports and do silly pranks that usually involves alot of people seeing my skin. As I go to get in bed Sasha stops me and points out if I sleep where I was planning to, giving Sasha lots of space and privacy, I would end up sleeping next to my step sister. That worried me as I've always had girlfriends, always shared a bed with them and always been known for a cuddler and copping a feel in the night. I let Sasha know I agreed with her thought process but warned her what may come to pass by sleeping to near to me and she surprised me with the line 'maybe I wanna get felt up' accompanied by a devilish smirk. Without waiting for a reply she stripped off to her bra and thong and hopped in next to me. She immediately threw her leg over mine and slid in next to me. I was shocked and let her know that at her being 18 and myself being 22 that I felt it was a big age gap.

It may not sound much but she was in college still where as I'd left school at 15 and been working manual labour jobs for the last 7 years and had the chance to experience alot of the world by then. Sasha laughed and let me know she was engaged to an old friend and a classmate of mine, making out she had seen her fair share of adventure. This had me intrigued but when she said the name I didn't recognise it. 'Never heard of him, are you sure he was in my year?' I asked. 'Definitely he was in your form group'. I racked my brains trying to recall the name but nothing came up. I wasn't the naughtiest kid in school but I hadn't toed the line so to speak which had made me popular, plus I was on most of the school sports teams so it kept me fit which definitely helped. I knew all the kids there was to know at our school, we had big year groups that all intermingled and had thier own cliques. 'He must be lying, there is no way we were friend's' I answered. Sasha fished her phone out and showed me a picture of him and it finely clicked. He was a dweeby needy kid that sat in the corner, never spoke, at least not to us, he would grass us in regularly to teachers for our behaviour after class but he was a nobody and certainly not my friend. It did annoy me. Apparently he had been telling Sasha we were good buddies, hanging out regularly before I moved away for my job. This whole time her hand had been slowly stroking my abs. It felt nice, I can't lie, I knew it felt wrong, she was my step sisters friend (always causes fallout) younger than me and engaged to boot. But I could not help my self 'I can't believe you agreed to marry a guy like him' I said 'you could do much better than him you are gorgeous!'

She lapped it up and immediately leaned in to kiss me whilst her hand trailed down to grasp me over my boxers as our tongues entwined. She commented on me being massive (I've seen the world, knew i wasn't destined to be a pornstar, and had an above average cock at 7 inches, but I was in no way massive). She moved down to use her tongue bar on my belled, first for me and I've been trying to convince every since that it's a good idea 😆 I resolved myself to just a bit of fooling around. My uncle was in the room and I was trying to be quiet and sneaky about things still.

I didn't think to much of her initial comment until I slid my hand in her soaking knickers and felt how tight she was. I struggled to fit my index finger into her and with that I knew i didn't have the will power to resist sinking my cock into that tight embrace. Sasha had amazing head skills for a girl that had only had one boyfriend and I'd come to realise was a one inch wonder. I ran my finger to the knuckle exploring the wonder of the inner depths of her pussy whilst rubbing my palm over her clit. She definitely appreciated the attention from the way she way humming on my dick!

I pulled her off my dick before I shot my load down her throat and laid her back so I could taste her. It didn't last long, even with a pillow clamped on her face the noise was too much. She confessed that was a first for her! Been a couple for a year and he'd not drank from her honeypot. I was amazed, she tasted so sweet and shivered everytime my tongue touched her lips.

I asked if she was on bc and she said no. I didn't have a condom and needed to not leave a mess everywhere, I was sure the dream was over until she said 'don't worry, just pull out and ill swallow it!'. We went with the spoon position as it allowed us to be not so obvious if someone came in or woke up. If It wasn't for the wetness and me already tickling her rosebud I would have swore I had the wrong hole as I lined my cock up. The tightness was immense and I had to brace my dick from bending as my hips piled the pressure forward.

My bellend popped in. She gasped into her pillow and I just savoured the feeling. She was cumming already, her already vise like pussy was twitching over and over onto my cock. I knew this was going to be fun. I slowly started to thrust my hips working myself a bit further in and out each time. It took 5 minutes to sink half my length into her. The noise was constant from Sasha. I checked in with her to make sure everything was okay continously and she assured me it was the best night of her young life. The sensations were too much and the anticipation of being fully hilted finally were excruciating, patience ran thin, I hooked her outer leg over mine and spread her as far as I could and started to bury myself into her.

All too soon I could feel the end coming near and I rolled onto my back and let her know thinking this was the time for her to back out and leave me with a ruined orgasm. Thankfully she was a dirty little minx and swallowed me whole and proceeded to give me the best head of my life even to this day 15 years later. She sucked me dry, I was spent. She cuddled up to me and we settled in for the night making small talk for a few minutes before pretending to sleep as my step sister came through the door.

She stood in the doorway staring at us for a good few minutes. It must have smelled of sex still. She eventually stripped off and got into bed next to her friend and I thought we had gotten away with it.

The next day I was soon to find out we werent as discreet as we had hoped!
