[M] I 19M had 33.33% chance of being the dad

This happened with my ex girlfriend. The relationship was intense, we were barely legal, horny AF and clueless. We never used condom and I would always pull out. We fucked at my house, hotels rooms, even in empty classrooms and didn’t think about consequences.
One day, I got to know she’s been cheating on me with 2 other guys. I was sad, and frustrated but didn’t know what to do. I called her over, and ended up screwing her one last time. I knew I had to end things and fucked her like there’s no tomorrow and came inside her. She asked me not to worry and that she’ll take morning after pills. I told her I knew she was cheating on me and broke up then and there.
Fast forward 3 months, I hear from my friend that my ex got pregnant and had to abort a few weeks back.

She could’ve been pregnant with anyone out of the 3 guys she was sleeping with including me. So, mathematically, there’s a good 33.33% chances that was mine.

I [M] [19] use gay men’s mouth while imagining face fucking a woman

So, it had been 2 months since I turned 18 and I was still moving on from a breakup. I’m straight and I’m supportive of LGBTQ+ community and have several gay friends. This one day, my fellow dudes and I were drunk and a guy friend of mine enquired how I’ve been doing since breakup and in sometime, our conversation escalated into topics related to sex. He said how hard it is to get laid for a gay man in our locality as he hasn’t come out of the closet yet. I empathised with him and said he’s a great friend and I would help him in anyway possible. He all of sudden grabbed my crotch, it was awkward and I felt kinda uncomfortable but didn’t say anything. I wouldn’t blame the alcohol but we both were indeed drunk. “show me your dick” he asked. I’ve been in situations where I’ve had to be naked in front my friends so I agreed and we went to my room. The moment we entered, he tried smooching with me but I stopped his advances. “Okay, I won’t do that. Just show me your dick” he said. I opened my zipper and the next moment he kneeled down and took my cock in his mouth. I’m straight but the blowjob did feel good. I felt a bit uncomfortable, so, I just closed my eyes and imagined a girl giving me a blowjob. The thought of getting a blowjob from a girl and using a guy’s mouth just for pleasure’s sake turned me on all the more. By now, I was rock hard and started face fucking him still my eyes closed tightly. After around 10 minutes of shoving my dick in his mouth, I came, and the amount of load was surprisingly a lot.
Later I found out this was a kink for many, a kink where they are being used as a cumdump by a straight guy. Since then, I’ve done this with 7 gay men.

[MF] I had sex with my HOD’s daughter in his cabin

I [19M] have always been on my HOD’s bad books. He finds silly reasons to point out and tell me what a bad student I am. Since my admission in this college, he’s done nothing but annoy me.
That being said, his daughter is a ravishing woman and most of my batch mates fantasise her. Though she’s hot and charming, and acts tough in front of other students due to the pressure of being the HOD’s daughter, she’s always been friendly with me. At some point of time, we agreed to have FWB relationship and this one time, a students fest was going on and no one was present in the academic block. She had the keys to her dad’s cabin and we decided to take advantage of this opportunity. She always wanted to get things heated up somewhere where she could get caught.
We went in, undressed ourselves and chose not to lock doors as no one was there but the thrill of getting busted turned us on.
I remembered once I stood at a spot while my HOD was scolding me for not being active in a club that was inactive anyway. Now, I was standing at the exact spot while his daughter kneeled down and sucked my balls dry.

[MF] I took my girlfriend’s sister’s virginity

I [19M] knew my girlfriend’s sister well and we are in each other’s social circle too. The other day, my girlfriend and I fought over something and didn’t talk for almost 2 weeks and her sister called me over to her private birthday party. I was held up with my college assignments but made time anyway hoping to resolve issues between my girlfriend’s and I. When I went there, her little sister invited me and informed that her sister won’t be making it to the party. I was worried but decided to loosen up a bit. After a few rounds of vodka, I was feeling trippy and decided to leave but her sister asked me to stay. I’m a terrible dancer but managed to pull some moves for the sake of it and my girlfriend’s sister started grinding against me. Now, I’ve never been sexually attracted to her but her ass grinding against me resulted in a huge boner. I bet she felt my erection and instead of stopping, she decided to enjoy it. I initially felt bad but the alcohol had already taken over and the music was intoxicating. In a few minutes, my hands were all over her and we started smooching. We headed towards an empty restroom stall and started making out. The music was playing in the background and her breathe against me turned me on all the more. She grabbed my crotch and slightly pressed them which resulted in a burning desire. When we both were semi naked and about to begin, she said “Slowly, I’m a virgin”. Now, I felt mixed emotions of cheating on my girlfriend, fucking her virgin sister but I was way too horny to let guilt stop me and inserted my erect cock inside her tight pussy anyway. “Oww” she whined which soon changed to gentle moans. To my surprise, in not time, she got worked up and started pushing against me in rhythm. We were high, our bodies were sweating a lot and were horny as hell while we fucked hard for around 20 mins or so.
My girlfriend doesn’t know about this and we still hookup from time to time. Maybe we will get caught or maybe we won’t but I’m totally enjoying what I’m having right now.
