[MF] I (M29) had sex with my best friend’s sister (F27) while her mom slept on the same room

A little background: I’ve been friends with this guy my whole life. We would sleep on each other houses almost every weekend when we were little. He has two younger sisters, Camille 27 and Katherine 25.
Camille had always had a crush on me. When we were kids, her parents would make jokes about us being destined to be together and I think that sank in.

This story happened 6 years ago, so we were 23/21 at the time.
Their mom had invited me to go on vacation with them. It would be Camille, their mom, three female friends of Camille and I on a 2 week trip to another country, and they were paying for my plane tickets. One week before our trip I went to their home to spend the week. My buddy had gone to another city to see his girlfriend, but I felt like home anyway, knowing his family for so long.

During this visit, Camille didn’t separate from me. She would go anywhere I was. One night we were at the pool and she was trying to get as close as possible and I tried to avoid her. I completely knew what was going on, I’ve always known about her crush on me, and it was really hard to not touch her back. She was wearing a nice bikini, suitable for the family. She’s 1.65 m tall, has tanned skin, a nice slim body with b cup tits and a perky little butt. So when she was close to me I’d grab her waist, but not more than that, even though she kept trying to grab my arm and hug me for more than an hour while I was trying to hide my erection under the water.

That same night after swimming she suggested we should watch a movie. She proposed only horror movies so her little sister didn’t join us. While we were watching she got as close as possible to me, and during the terrifying parts she hugged me and didn’t let go. I was horny as fuck, I wanted to put my cock in her mouth so bad! After the movie ended she asked me to close my eyes. I knew what was coming and I said to myself “why not”, so I closed my eyes and she kissed me. I was really nervous but horny too, so I went along. I grabbed her by the waist and put my hand under her tank top and grabbed her boob. It was amazing, really firm and it fit right in my hand. She started rubbing my cock over my jeans, feeling my hardness. We stayed like that for a few minutes until she released the kiss and said “we have plenty of time to keep doing this on our vacation. Think about it” and left. And damn I thought about it. Specially because after that she was always wearing tight tank tops and really short shorts that showed half her butt.

Sadly, nothing else happened that week. And we flew to our destination. Turns out Camille’s friends were annoying brats, so I didn’t interact much with them. But those days there were LOTS of drama. They were arguing about everything. At one point, after a week, I got fed up and asked Camille and her mom to separate from those bitches and they agreed. That was yet another argument, but at least I wouldn’t see them until the flight back home.
After that we rented a two bed room in a cheap hotel. Camille and her mom would sleep in one bed and I would sleep in the other one. Mine was right in front of the TV, and that was Camille’s excuse to be on my bed every night before sleeping.

One night Camille and I decided to go drinking, her mom didn’t come with us because she was taking sleeping pills so she used to go to bed very early and was a heavy sleeper. We went to a few bars and found one that we both liked, it was cheap and there was live music. After that we were pretty drunk, but not that much. On our way home Camille didn’t take her hands off me and I didn’t back up. We were kissing the whole way to the hotel. But still, I wasn’t sure if I wanted to fuck her. Kissing was nice and hot, but I didn’t dare to have sex with her. Besides, we didn’t have anywhere to do it. So we went back to our room. Her mom was sleeping heavily, we made a lot of noise and she didn’t even notice.

We went to bed and just like every night, Camille went to my bed to watch TV, but she didn’t even turn it on. She started kissing me and grabbed my already hard cock. I was shocked and quietly asked ” what about your mom!” “She won’t even notice” she replied with a smirk on her face. I had been holding back for weeks and I couldn’t help it anymore. I kissed her and put my hand under her pajamas, she was dripping wet. I put two fingers inside her and started pressing them against her vagina, while rubbing her clit with the palm of my hand. With my other hand I took my precum in my finger and put it in her mouth, she sucked it all. At this point I was desperate. I turned her around, took of her pajama pants and penetrated her, balls deep. I started rubbing her clit with one hand and grabbed her breasts with the other, while kissing, licking and biting her neck.
We were spooning like that for a while when suddenly her mom woke up to go to the bathroom. We pretended to be asleep under the covers, not moving a muscle. We waited while she used the bathroom, with my penis inside Camille not moving at all. Her mom went back to bed and we still didn’t move, too nervous to do anything. That’s when we heard her snore. We took a good silent laugh and when we relaxed we kept going. I was slowly but firmly thrusting her avoiding making noise, putting my whole cock inside her with every push while still rubbing her clit and she started shaking and moving uncontrollably without making a sound, she grabbed be by the ass to make me thrust faster and harder, she shook even more intensely and then… Released. This was my cue to fill her with cum, so I started thrusting faster, grabbing her by her hip and I came inside her. It was so intense that I was about to faint. She stood up to clean up and her legs were full of cum, she looked at me and smiled.

After that night we had sex every time we had the chance, we wouldn’t take or hands off each other when her mom wasn’t looking and we took every chance we had to be alone.
