I [M21] was seduced by my best friends sister [F18] [MF]

I actually posted this story a couple months ago and it blew up with over 1.5k upvotes within 12 hours, but I deleted it because some events unfolded that actually made this story relevant again and I wanted to follow through with some things first. Ive made a throwaway, and some recent life stuff has occurred that I really think this sub would enjoy that I’ll share as extra parts if this gets the same type of attention it got before.

I’m currently 25 and this took place about five years ago. Honestly, there isn’t any exaggeration in this story.

I grew up in a small town, and when I went off to college, my best friend stayed in town working towards his trade. Im very introverted, and spent a lot of my time back home with Mike as I was only going to school a half hour away and wasn’t into the fraternity/partying scene.

My friend Mike was a really great down to earth dude. I’ve known him since 7th grade and we still talk regularly even though hes now across the country. During this time, he was raised by a single mom who was a doctor so she was always gone at night. She worked the graveyard shift.

When I’d go over to hangout at his place with just ourselves wed often just play darts and also talk about whatever young men talk about. Girls, sports, music, and we were in touch with ourselves and our feminine sides so we’d often talk about emotions and deeper things about ourselves. Weed was usually always involved.

His sister, Katie, who was 18 at the time, was very introverted as well. She had friends, but she actually liked just hanging by herself or with us on the weekends. It was natural for her to be around and to also be included in these really personal conversations.

Katie was and is unbelievably attractive. She’s a brunette, only 5 ft 4 but she dances competitively so her body is tight, and her ass sticks out like a peach and she’s easily a DD.

I tried not to think of her sexually because I’d known her for quite a while and she was honestly one of my closest friends at this point.

This started near the end of my sophomore year of college, and she had just turned 18 and was about to graduate highschool.

I had decided that I needed a break from weed and was hanging out in their living room by myself just watching some sitcom while Mike and another friend were outside smoking and hanging out. Katie came out of her room and we started talking about why I was hanging by myself, and I told her I needed distance from weed and that I was going to be drug tested.

She sat next to me and we started talking about life. She was actually going to go to the same school as me next year. Now, I should inform you that I spent my first two years of college being an absolute gym rat, and that I gained a lot of weight. I was freakishly skinny growing up but had finally came together with a full beard and 30 or so lbs of muscle in a very short time. Katie then looked right at me and said “I’m thankful you’re going to be at the same university… You make me feel OK about everything, especially with how improved your life is since you started. I mean, you look amazing. It’s really great”… i just responded with a “thank you, that means a lot coming from someone i care about”

Suddenly she rested her head on my shoulder/chest area and her hand on my waist/upper thigh. She was wearing these thin felt like booty shorts that hugged her ass and a tank top that was exposing the sides of her pink bra. The way she positioned her body had her cleavage exposed to me and her ass bent and sticking out, with her eyes glued towards the TV, giving me the A-OK to completely soak up the moment and her body.

Within 5 seconds of her laying next to me, I was rock hard and my cock was noticably throbbing in my shorts. I felt Katie squeeze my upper thigh, which made my cock twitch again in anticipation. I had the sudden realization that Mike was just outside and they could come in at any moment, and that this my best friends little sister. I got up and said I had to use the bathroom, and splashed some cold water in my face until my boner was kind of gone. It was one of those raging boners that you couldn’t tell to go away.

I left without saying bye to Katie and drove home and told myself that I shouldn’t be doing this. …But, this felt different. I knew she liked me and I liked her. I had this feeling deep down that I knew I couldn’t control this.

So things were normal for a week, and then I stopped by Mikes house again on a Friday night and we smoked and hung out like normal with a couple more buddies this time around. I had just landed my internship so I had decided to smoke. Eventually Katie come out to say hi and everything seemed normal. Once everyone was distracted playing darts and conversing, she looked at me and smirked. It felt like she was looking through my soul. She knew I wanted her. She knew she got my cock throbbing in seconds. Her smirk and glare was devious and there was no mistaking it was ridiculously sexual. I gave it right back and smiled and shook my head at her. With that she said good night to everyone. No one really ackknoweldged it, but as she left she gave me one more glance. I had to pace around their garage for a bit because I was feeling myself getting hard. Thankfully, no one noticed or even thought anything was up, especially because everyone was usually drinking or getting high.

This happened for a few more weeks, each week it slowly escalated further. From the looks, to her putting her hand on my back when I walked by her when no one was looking, to me putting my hand on the small of her back when we were going inside ahead of everyone else just out of sight.

One week I decided to take a break from weed and was hanging out in their living room by myself. Katie came in with a yoga mat, those butt hugging shorts and just a sports bra. She asked if she could do some yoga for a bit and I said yeah I don’t mind. She set up to the left of me, just enough so I didn’t have to turn my head to see what she was doing. When she started she smirked at me and was doing her thing, half folds, planks, and then she went into downward dog. Her ass shot straight back and her shorts basically couldn’t hide her thick pussy lips.She wasn’t wearing anything under her shorts and was exposing half her pussy to me. I was already hard, and she looked at me with her face upside down and ass in the air. The garage door closed and we heard footsteps from the porch, so Katie wrapped it up and sped off before they got in, running her hand through my hair as she walked by. I knew it was only a matter of time.

So… Fast forward two weeks and Mike decided to have kind of a party, which was just a few more people than normal and excessive hard alcohol. I didn’t drink that much, and I noticed Katie was taking it easy as well. I was about to head out, and went to say bye to Mine. “hey, man I’m heading out”… No response. He was dead asleep, snoring too.

I walked into the living room which was dimly lit with a candle. Everyone else had left and Mike was fast asleep on the far side of the house.

I told Katie “hey I think I’m heading out, have a good one” I said it with an air of sarcasm, like we both knew I wasn’t fucking going anywhere.

She looked at me a slight frown and said “don’t you want to smoke my pax with me ?”

I sat next to her and she turned it on and a couple seconds later we were taking rips. Her body was glowing in the candlelight and like usual, she was wearing tight booty shorts and a tanktop, her cleavage staring at me and her brown eyes looking right through me. Without saying anything she leaned in and kissed me, while at the same time throwing her leg over my waist and straddling me. While our tongues were twisting she slowly started to grind on top of me, both of us letting out small moans. I reached down and her shorts were soaked through. My cock was also basically ripping through my jeans. This was weeks of foreplay finally coming together. We were both so turned on that we didn’t even talk through any of this. Just raw primal energy was ripping through both of us. Our shirts came off and she let me play with her perfectly sized boobs and tits, just big enough so that I couldn’t hold it in my hand.

Again, without saying anything she guided herself on to me. We were letting our moans and pure sexual instinct tell us what to do. We didn’t even discuss condoms, but when she finally fell to the base of my shaft she looked deeply into my eyes and said “I got an IUD a couple months ago by the way” … I responded by taking my hand to the side of her face and kissing her deeply, while at the same time slowly thrusting into her.

She sped up her grinding and we started kissing deeply again. I took my hands and grabbed her ass and started pushing her ass in rythym with her grinding, while also slightly angling and thrusting my cock as well. “Katie I’m about to cum” she looked at me and said “me too”, and right after she said that she shoved her boobs in my face and actually aligned it perfectly so a tit went in my mouth and moaned out “please, cum in me babe” I let out a rough moan with her tit in my mouth and came the hardest I have in my life up to that point. On my second or third pulse of cum I felt her pussy throb and her upper body collapsed on top me. I was still riding this orgasm wave and was feeling her body convulse and hard nipples poke my chest while she came over and over.

We cleaned ourselves up and I kissed her goodbye.

Mike still doesn’t know that’s when we first hooked up. I do have more stories with Katie and actually some more just popped up due to quarantine…

And I did feel about what I did at first but I don’t regret it.
