How I [M] made a highschool acquaintances [F] my cumslut more than 10 years later.

Long time lurker here with finally my own story worth sharing. A few things: please excuse my English, not my first language. Also, trigger warning: this story is about cheating. And this might be a long story.

So, this story started in November when I went to a school reunion. I went with three friends to a pregame party with several people from my year.
We were between 15 and 20 people who met at around 6 or 7 pm at a garage of one of the girls. It was cold but that's what the booze was for I guess.

Now, I never was the very popular guy and did not have much to do with most from my year. But I was rather friendly with most, so we arrived, said hello to everybody and I even got a compliment from one of the girls for the winter coat I was wearing. Maybe now is the time to give you an idea of what I look like: I'm 6'1 (186cm for our European friends), have dark blonde/light brown hair, blue eyes and am on the thinner side but not too thin. Id rate myself as a solid 6, mediocre, nothing fancy but not ugly at any means.

As I am not much of a drinker, I planned on sticking to two or three beers for the night and then switch to soft drinks.
Enter Sophie, the main character of this story. Sophie is impossible not to notice. She's about 5'2 (158cm), a gymnast goddess in a compact frame. Long, curly blonde hair that sometimes catches a red shimmer. Eyes that shift between green and blue with specks of warm brown. Pale skin with freckles. An E-cup chest that defies gravity, toned legs sculpted from endless training, and an ass so perfect, it could have its own orbit. You look at her and you know this girl works out daily. Then she laughs – bright, infectious, the kind that drags you in, whether you want it or not.

Even though we had several friends in common, we never really clicked during school. She invited me to her 18th birthday, which surprised me pretty much as I did not expected that, but it was fun. It was a very innocent party with games and a contest (which I actually won, or had a shared first place. Proudest moment of my life). Since we weren't close, I barely knew what she liked, so I just gave her one of my favourite books at the time - Priestess of the White by Trudi Canavan – which still sits high on my list today.

After school ended, we saw each other probably once in the ten years that passed and did not talk to each other.
So, I was there in the garage, holding my cup of random soft drink X, already being done with my beers for the evening. Some of the people there started a drinking game which I masterly dodged to participate in, but Sophie did not let it slide. She gathered two or three of the people who were not playing and started talking them into drinking with her. Most of them agreed, I tried not to, but she would not have it. She got a bottle of green stuff that tastes like toothpaste and no matter what I said, in the end, she probably made me drink three shots. This is where my evening then stopped being a relaxed, chill evening, as once I get tipsy, I get in the mood to continue drinking.
We ended up in the car of one of my friends driving to the school reunion, singing emptiness machine from the bottom of our hearts. At the reunion, I hung out with one of my friends for most of the time, but usually you just talk to anyone you mildly remember. Many of them tipsy or wasted. You (or at least I in this case) drunkenly talk to old teachers, it is fun while it lasts and embarrassing once you wake up.
I did not see Sophie once we parted at our arrival at the school, but she did send me a snap during the pregame of a friend and I that she took and she texted me during the night to tell me that I should not change my hair, as she liked it the way I had it now.

We then started sending the occasional random snap or message, maybe once every other day. Then, just after new year's, I went to visit my grandmother down south. I had my own little flat upstairs in her house, and when my parents, my grandmother and her husband talked or watched TV, I was upstairs reading Stormlight Archives, rushing through a few hundred pages on the first day, which was my plan, as I wanted to know how the story ended. Again, enter Sophie.

She sent me a random snap and, as I was just laying there on the bed, reading, I immediately answered. So did she. She was chilling on her couch, she and her boyfriend had some friends over, drinking booze which she was not feeling at that moment, which is why she was on her phone. We started talking, she mentioned that she was not feeling well at the moment and, cutie that I am, I asked her what's wrong. She opened up and told me about all the shit that has been going on in her life and I tried to comfort her. After some time chatting, I added something along the lines of "you are a cool person, kind, caring, good looking (it was smoother than that, but you get the idea) and your bf is a very lucky guy and should slide into your dms daily to tell you that you are! And if he doesn't.. 'sliding into your dms'"

I meant it as a light-hearted, slightly flirty joke, with no intentions whatsoever, but meant honestly. As I had a girlfriend (Violet) at the time, I didn't think any of it.
Apparently, I hit a nerve. She instantly flirted back. Fast forward to the next day: we woke up and immediately continued texting. I had nothing planned for the day except reading, neither did she. So we just picked up where we left it.
For ever, I had a few thresholds I told myself I'd never cross. Flirting is fine in my opinion, who cares. It's just fun and hurts nobody. But receiving nudes is another thing entirely. So I always told myself, if it ever came to that, I'd tell them it is a lovely picture and it sucks being in a relationship right now, but I am and this is as far as I can go, sorry.
But when Sophie told me she was thinking about two reasons to make my day (as a thank you for being there for her the night before), instead of saying no, I, fully knowing what she probably meant, just answered "Oh? What reasons?"

I got two pretty good reasons. A picture of her, standing in front of the mirror, expertly done so the lower edge of the mirror cuts off just at her hip. Her phone hides her eyes and nose, but you can see half of her lips in a very light smirk. A bar with the words "Good Morning" in front of her breasts, just enough to hide her nipples, but not enough (by far) to hide her full breasts. Even though the picture showed her from the front, you could still see her fit butt coming around the edges of her side. It was the most sexy picture I had ever seen to that day. It was a masterpiece, sculpted by a great artist. I was smitten and did not say anything about this being as far as I could go.

We just continued flirting, heavily. At around 10am, I had to go downstairs to have breakfast with my family and I was like "how exactly should I do this now, going down to my mother and grandparents, hard as fuck? Thanks for sending me down like that." She only laughed at me with one of those "sorry"-messages where you just know they are not sorry at all.

This is pretty much how the next two days went. I don't think I got any more pictures, but I sent one from the bathtub where I had to shower. It was built years back, for old and smaller people. So I had to kneel to fit under the shower and to be able to see anything above my chest in the mirror. Here, I stuck to one of my thresholds: I would never show myself fully nude. Only what people could also see while going swimming etc.

Then the day of departure came, and I knew, this could not continue, as back home, my girlfriend waited in our flat. With this, it was clear what we had to do..
So obviously, we chatted normally on WhatsApp and moved all spicy stuff to SC. I would tell her when I was on my way home from work, so she would know to only text sfw stuff from now on. This continued for like a week, where we non-stop messaged each other. We talked about everything, flirty stuff but also general or emotional/intimate topics. We just told each other everything, what was happening that day, what had happened in our lives at any point.. The connection was unreal. It was just so easy talking to her. At the gym, my friend also noticed and was so confused, he asked "how can you even talk so much to anyone, what is there to even talk about?"

By now, we were heavily flirting, getting sexual and sending more frisky pictures. After about one week, on a Saturday, Violet was gone for the day when Sophie somehow let me know she was horny. So I told her to masturbate. But then continued to tell her how to do it. Up until when I told her when to cum.

The next two days, I thought about how I went too far, how that was just too much. I felt bad and guilty about it. So I called her when I was alone and told her we couldn't go on like this. It was so much fun and I really enjoyed it, but I just could not continue like that. She told me how much she respected me for telling her like that, that it is understandable and fine and how she values me as a friend. So we decided to stop the flirty, nsfw part of this friendship and continue being friends, as we really started to enjoy each other's company and had become really close friends in such a short time, we did not want to lose that.

We made it three days. And this is where it "deteriorated" quickly. From here on, it didn't take us long to figure out that she wants to be dominated. So I started telling her when she was allowed to touch herself. If I didn't say anything, she wasn't allowed to. Which was quite the predicament for her, as, apparently, she used to get herself off quite a lot.

We were full on sexting now. I rarely called her Sophie, instead calling her my cumslut, whore, a piece to use (it gets lost in translation I guess, but the thought behind it might be grasped). And the things I made her do.. I told her to use her cum to write those words on her body, where to put each letter. Each day, she was supposed to write an "M" on her lips, coming from when I made her write cumslut on herself. The "M" ended up on her lips and she enjoyed tasting herself. I loved the thought of it. That's how that came to be.
I told her to lick her fingers clean after masturbating, to finger both her pussy and her ass. I told her to wear a butt plug when she went grocery shopping and she got herself off for me in the changing room of a shopping mall. When we figured out that she took the book I gifted her years ago with her, from her hometown to where she lived then, we were amazed. And I made her read it out aloud, fingering herself while not being allowed to cum and record it for me.
The two most memorable things were when I told her to masturbate while her bf had a friend over. Sophie went to bed quite early and was just about to get herself off, when the friend knocked to say goodbye. She said she'd be out in a minute, dressed herself, gave her a hug and went to bed again. I loved it. And my favourite moment was when she was at a friends to help her with some of her wedding-planning. They drank some alcohol and Sophie got tipsy. And when Sophie gets tipsy, she gets needy. So I encouraged that and gave my best to get her even more riled up. I had to work on that weekend and when I changed into the work clothes, I took a video of me slowly undressing. Apparently, the moment when I took off my belt led to a visible reaction in her face, as she later told me her friend asked her if everything is alright and something happened. Later, when she slept over at her friends, in the same bed, I made her get off right next to her and whisper my name while she came.
To only name a few things I made her do.

The phone sex started when she told me she was watching Legend of Vox Machina, which I had seen the first two season of and then proposed to watch season two and three together. I told her to start touching herself while watching, which kind of conditioned her to not really being very focused whenever we watched the series. After maybe 2 more weeks, while we had phone sex, I started the video and we looked at each other while we masturbated. (Obviously, my rule of "not showing everything" was long broken).

During that time, she earned one big punishment when she got herself off twice in a day without being allowed to or even asking. I just wasn't sure yet what that punishment would be. One thing I did for something else where she didn't listen was I made her stop writing the "M" on her lips and she really hated that. But she was a good girl (a name she loved being called) and did stop, until I allowed her to continue writing again. We also established a list where, every time she didn't listen to me, I'd write down a number of hits on her ass she earned for that.

But, that was as far as it would ever get, as she lived in another city, maybe five to six hours away by car. Not a trip you could sneakily do in a day without having your partner figure it out.

Until Violet and her cousin April told me they wanted Violet and me to visit April in her city. Which is where Sophie lived too. They demanded I come. So I said sure. They planned on us being there three days, I said I would hang out one of those days with my friend then.

When I told Sophie, we started thinking about what we could do, go to a café for brunch, maybe cinema, she could show me around the city. Which was all dismissed when her bf told her he would be gone that exact day too. So she just asked me if we want to have breakfast at her place, she could show me where she lived, they had a small nature reserve right next to their flat that we could walk to. We did not finalize the plans of what we wanted to do, with one exception: my arrival was planned out. I would enter her flat, she would close the door, kneel down in front of me and start sucking me.

The day came where I drove Violet and myself to her cousins. The traffic was horrifying, we took about seven hours. We then sorted us out, me getting the couch in the living room and the two girls sleeping in her bed, which I was happy with. We spent the day and evening in her flat and going around the city, it was fun. But I only wanted to go to sleep so I could wake up the next day. The plan was to leave at 8am so I could be at Sophies place at 9 and stay until 5pm.

I leave at around 8:10 and during the whole drive, I'm nervous. I'm pretty sure I'm about to cheat and I feel way too little remorse for it. I arrive at 9:10 and by now, I'm a nervous wreck inside. I ring and the door opens. I know I have to take one set of stairs to get up to her flat. While I go upstairs, she already starts talking to me. I can't see her yet because her door is behind me. She asks if I saw the ugly statue of a lion in front of the house, which I actually specifically looked for, but did not see. Which is impossible to miss, as it is over a meter tall and directly next to the path to the front door. Well.. I must have been even a little more nervous.
I reach the top of the stairs and can now turn towards her door.
There she stands. (To be honest, I have no idea anymore what she wore. I remembered on that day, but only barely. I hardly noticed much besides her and her face.)

I enter, she closes the door and she hugs me. I don't know how long we stand there just holding on to each other. It isn't one of those weak alibi hugs, but one where you really hold on tight. It is a great hug. We stand there for a couple of minutes, not saying much, just embracing each other and enjoying the feeling of finally being able to be with each other.
Then, she takes off my jacket, puts it somewhere, asks "may I?" and kneels in front of me.
I have two things I wanted to say before I'd do anything. I want her to think about it again, if she really wants to do this, as she also is in a relationship and there'd be no going back from cheating. Second, I want her to think about neighbours. But when she asks "may I", I figure she really wants this, so I make a halfass answer by only saying "if you want". The neighbours I don't mention. After all, it is only her blowing me, I won't get too loud. Plus, it won't be long that she could suck me there, I have other plans.
She opens my belt and pulls down my pants.
I have no idea when exactly I got hard. Had I been hard the whole hug? Only afterwards when she started undressing me? Sometime in between or already when I rang the bell? I have no idea. But apparently, she had been waiting for that moment as long as I had. Because the moment she sees my cock, she just breathes "my god" and starts sucking it. (Now, im not overtly well endowed or anything, again, I think I'm pretty mediocre with 5,9 inches [15cm] on a good day, but apparently, she was pleased)

Not long after, I make her stop, tell her to undress and then let her kneel in the middle of the hallway while I dress myself again and walk through the flat. I look into every room, looking for a mirror that goes all the way down to the floor. Sadly, I can't find any. So I have to change my plans for her punishment.
Meanwhile, she just continues kneeling there completely nude, waiting patiently for me to tell her what to do.

I come back and tell her to get up. I pull her to her bedroom and ask where the box with her toys is.  I get it, put the middle sized plug in my mouth and hand it to her. She asks "now?" and I nod. She lets out a soft moan, bends over and needs a minute to put it in.
Then, I ask her where she has something to blindfold her. By now, she kneels again. I get a bandana, put in on her and then pull her to her feet again. I guide her towards the back half of her room. That part is elevated by a platform and separated from the rest of the room with a shelf.
I guide her up the three stairs. In the corner is an armchair where I sit her down and hand her her vibrator.

I tell her to masturbate for me. I then explain that the most hits she earned was by saying bad and mean stuff about herself. So I want her to list things that she likes about herself while she makes herself come.
It doesn't take long for her to come. I give her a few seconds. Then I tell her to do it again. After all, she earned this punishment by masturbating twice when she was not allowed to, so obviously she can't get enough. So I tell her to come again. While she starts again, I tell her that, if she wasn't blindfolded, she could see me taking off my belt. This gets another moan out of her. I then put the belt around her neck and pull it "tight".
It doesn't take long for her to come again. I take off the belt, then I lick some of the vibrator clean, let her clean up the rest and take off the blindfold. After a short break for her, I kneel down in front of her sitting in her chair and start licking her. I do that for a while, enjoying the taste of her sweet pussy for the first time, then I get on top of her on the chair and fuck her mouth while she fingers herself. One or two tears start coming out of her eyes, but we talked about this during the weeks prior, so I know she wants this. Then, I get down and fuck her while she still sits in the chair. The moment I first enter her pussy, feeling her warmth and how incredibly wet she is for me.. I am in heaven. I sit down on the chair, she starts sucking me until I tell her to climb on top and ride me. Somewhere between me licking her and her being on top, she comes a third time. We proceed to her bed, she's laying on her back, I'm on top of her. I take her hands, put them over her head and hold them there while I fuck her hard. I turn her around so she's on her belly and I fuck her. It can't be too long until we're both close. (At this point, I'm amazed at how long I've managed already. I expected to cum within minutes with the teasing for three months, her being the hottest woman I've ever even been close to being with and being exactly what I wished for my whole life, as well as me not having had sex without a condom for at least 6 years.)

Then we both cum. Sadly, I kind of fuck up and slipp out halfway, so some of my cum lands on her lower back and butt, with quite a large amount ending up on her blanket. But she still got some in her.

We catch our breath for a short while, then clean up and make breakfast. By now, it's around 11:00am. Where exactly the time went, we both have no idea, but apparently, we just fucked for over an hour.

We bake some bread loafs in the oven, only interrupting for me bending her over, pulling down her pants and spanking her after she was bratty. I can't eat much due to me being overwhelmed by everything, the situation, her. We just chill on the couch, talk about random stuff, how we enjoyed the sex and everything about it, how comfortable we feel. At one point, when I make a joke at her expense, she calls me a jerk. I don't say anything, just wait for her to realize what she has just done. It takes her a few seconds and then she bursts out into a wild laugh while I write down quite a few hits she just earned.

Maybe around 2pm, while we just cuddle on the couch and I massage her neck and shoulders, I make her get the book. She gets up, then sits between my legs and leans back into my chest. I let her read for a short time, then I start moving my hands over her thighs and start lightly touching her over her pants. She starts breathing more heavily and asks how she is supposed to read like this. As I am always happy to help and offer words of wisdom, I tell her to just concentrate and put some effort into it.
After a while, I start moving into her pants, or at least try. They are rather tight, so instead, I get up and take off her pants and panties. I kneel down in front of the couch and start licking her again, to which she says: "If you continue doing this, you will have kneeled more today than I have."
But she manages reading quite well, only needing a short breather every few words. Until I make her get on all four and position myself behind her to fuck her doggystyle. Again, she asks how she is supposed to continue reading, but again, she manages, albeit less fluent than before. But when I put my finger in her ass, I quickly realize she won't be able to read much longer. So I lean forward, pushing myself deeper into her, take the book out of her hands and put it aside.  Then, I start fucking her ass. This is the first time for me and she had not have anal for over a year, but it feels amazing. The thought of using all her holes, the thought of her letting me use all her holes. Seeing her in front of me with my cock inside of her. It is unbelievable.

Next, she kneels in front of me and sucks me for a while, until I tell her to get on top of me and slide it back into her ass. Now this position was the first time for her as well, taking it in her ass while being on top.

We fuck like that for a few minutes, then we somehow just stop. Not because anything happened or it did not feel good. Quite the opposite. It just happens naturally, we both feel so satisfied and comfortable, even though we did not come. We just enjoy it. We had no orgasm, but it is as if our "minds" had been satisfied by the sex. So she just lays on top of me and we cuddle and talk.

We just enjoy feeling and being close to each other for the next 1 ½ or two hours, until I make the next thing we talked about happen. We talked about her being my freeuse slut, how she loves the idea of me just using her whenever I want. So, kind of out of nowhere, I tell her to turn around and lay on the side. I fuck her from behind and I tell her to get close. Once she's on the edge, I command her to get on her knees in front of me and stay on the edge. And when she jerks me off onto her face, I want her to come. So that is exactly what she does.

I cum over her face, dripping down her breasts, onto her legs and the floor, while she cums as well.

I turn around, grab her phone and take two pictures of her, kneeling on the floor, staring up at me with my cum all over her. And I know, this is a picture that will stay in my mind for the rest of my life, together with everything that happened on that day.
