The summer me and my straight bestfriend who had a girlfriend got freaky
This started March 2023 when me (m18) and my ex girlfriend (f18)(I’ll call her Adi) got added to a groupchat on instagram by her at the time boyfriend (ill call him Cal) with a few of his friends that I didn’t know, at first it was just sending reels and chatting. A few days later I get a friend request on instagram from one of the guys in the groupchat (ill call him Seb) (m18), I was confused because I didn’t really know him and we only talked a few times in the group chat, I accept him and he immediately texts me privately, we then start talking pretty much every day and he used to stay up really late to talk to me (because of the 7+ hour time difference).
After a week of talking we become closer and we plan to meet up when he gets back (he was on holiday in the Netherlands at the time). So when the time came to meet up I went to his apartment building and was sitting by the pool waiting for him to come down (we just planned to hangout and go get food) and im texting him wondering where he was. I then see someone on the opposite side of the pool wearing headphones and dancing, so I send a picture to Seb and then I realised it was him (it was dark and I have shit eyesight), I then went round the back of the apartment building to go to the other side of the building, he realised I had gone so was looking for me and I snuck behind him scaring him. After that whole fiasco we went to some alleyways and were smashing bottles (I know immature), he then said to me “my dad said the other day that he’d rather him date a guy than a black girl” after that I was thinking okay wow random, besides the casual racism he was pretty nice and comforting to talk to.
Fast forewords to just before the second time we met, I was texting him and I sent a picture of a small carrot and said “does this remind you of anything?” He said something along the lines with “it looks like Caleb’s dick” (for backstory Caleb was infamous in our city for being a forceful person putting it lightly, he wasn’t a good person) then Seb said “he’s uncircumcised though” I said “what are you” because I was curious and I thought this guy was straight so didn’t think he’d actually reply, he then replied “idkk” I then asked “how don’t you know???” He then said “you will see” I literally paused and put my phone down because I thought he was just playing, you know how straight guys are, I then said “wish” he replied “wish? why wish” I then replied “cuz” he replied “then make it true” this time I was truly dumbfounded and had to take a break from my phone.
So the time came to our second hang out, I think we did pretty much the same thing as before except we went to the cinema to watch a movie. After the movie we went to his house to chill and listen to music. I stayed at Seb’s house for several hours and it was getting late and he said to me “why don’t you stay here tonight because the metro is closed and midnight surcharge is expensive, just go in the morning” I thought to myself that it was strange him asking me to stay over but I agreed. When it was about 1am we decided to go to sleep so he took off his shirt and shorts and got into bed (for context he had a single bed so it was tint) I also got into bed, I took off my shirt but kept my shorts on. For a while we’re just on our phone and then I put mine down to go sleep, at this point he’s facing away from me and I’m facing his back (we’re facing the same direction) and I feel him thrust back into me, I didn’t think much of it he’s probably just getting comfy or smthn so I just let it slide, BUT then he did it a second time and I was confused because why is this straight guy doing this, he keeps doing it and as a normal reaction to someone that’s into men has I get an erection, he feels it and is still basically grinding onto my crotch, he then puts his hand back and down my underwear and starts massaging it. He’s doing that for a while and then grabs my hand and puts it on his and I start doing the same, when I feel it I think to myself this shits huge it’s gotta be like 7.5 - 8 inches long and thick. Maybe 10 mins go past of us jerking each other off, Seb turns onto his back and we start making out and then he pulls his underwear down and pushes my head down to start giving him head, he’s moaning and shit, I didn’t think Seb who was a straight guy would do this. When it came to busting I asked where should I do it and he replied “do it on my face” so it do it and some of it gets into his mouth and he tastes it and says “mmm it tastes sweet” then he swallows, after a while he’s about to bust and then he does it on my chest because im sitting on top of him. Then the next morning we are chill like nothing happened (not in a way like refusing it happened just like normal thing like if you’re in a relationship kinda way). but damn he’d always be wearing tight shorts and every time I saw his bulge I went mental.
After that one night he started treating me really good, I’d heard from his friends and stuff that he wasn’t that nice and he was kinda a dick to them but he was genuinely the opposite to that. Every week from then on we’d have sleepovers and do the same thing, after the initial month it went from having sleepovers once a week to having sleepovers up to 4 times a week and doing that freaky stuff. Seb and I would be hanging out pretty much every day, there would be days where we’d not go home for 48 hours and just roam the streets listening to music and hanging out (stuff also happened out there). One night Cal asked to have a sleepover with us, and we both said no because I guess we liked our alone time together. Seb later asked me to be his FWB and I was like sure fuck it why not.
A few months had passed it was May/June Cal tells me about Seb having a girlfriend, I didn’t believe him because Seb never told me about her and I never saw him with her, after I found out about the girlfriend i confronted him about her he basically just told me that they were just talking and he didn’t really like her so would end it with her, honestly I didn’t really care that he was speaking to other people because we weren’t in a relationship so why should I be mad. If I had known they were still dating the whole time I would’ve ended it because after a while I became really good friends with her and respectfully like wtf. Another few weeks pass and Seb was like “you wanna come with me to meet some girls” I was like “yeah sure bro” so we walked to where they were and there was a bridge to cross the road, as we were going up the bridge Seb slapped my ass (Icl I have a fat ass so I don’t blame him) and so as a guy my instant reaction was to kick him as I was going up the stairs and this mf drops his phone off the bridge, I feel bad so I go down to get it and surprisingly the screen has only got a mid sized crack and a few scratches, we move on and keep walking to the other side of the bridge to the girls. Once we get there there’s about 5 girls I think they were French girls and they had a dog, this whole time it’s pretty much just me talking to them and playing with their dogs, Seb is acting reallt antisocial and just awkwardly standing there. Seb’s not feeling it and so we go back to my house, and guess what happens…we get freaky again.
A month before I moved country Seb invited to me hangout with a girl (the girlfriend from before that he told me he stopped talking to) so I go along with them, this whole time im like third wheeling them. Every time I hung out with them I started to hate the girl more and more, but eventually I mature and start thinking it’s not that deep and we became friends.
Holding this secret for such a long time is soo heavy (like his cock). Sadly all good things come to an end, the last night I was in the country all my furniture was gone and I just had a mattress on the floor, me and Seb were just lying there next to eachother looking out the window and talking, trying to hold back tears (at this point I hadn’t cried for several years) I wanted to continue this FWB situation but it would because difficult with thousands of km distance. For one last time we got freaky and that was the safest BJ I’ve ever given, we both felt sad at that moment. After I had left we started drifting apart and I already knew this would happen because he’s well known for not being that good of a Texter (irl he was good at talking).
Sometime last year (2025) I texted him on WhatsApp to get closure of the whole situation back then. Seb proceeds to basically call me crazy and saying I’m tripping out, I tell him to stop denying it and im trying to reassure him that I won’t expose him but he won’t budge, I send him screenshots of the texts of him talking about hooking up and he replies “that’s crazy, I did not type that gng”. After that I just gave up because it really feels shit being gaslit and shit.
A month ago (April 2026) I texted Cal and told him the whole story about me and Seb, told him every single detail (more than in this story), his response was like “I always knew he was bi/bicurious” he wasn’t even surprised, I then said “how??” He repkied “well back in 2024 me and him one time jerked eachother off and I knew he liked it”, that night I found out Cal was also Bi, what is my life.
Hope you enjoyed my story!
Should I tell the girl that her bf cheated on her with me? Or do I just keep it to myself because it’s been so long and she’s healed from HIM.
