I (19M) fucked my (36F) mom's friend

Okay so, this happened a couple years ago. I used to leave in a city 7 hours from the capital with just my mom.

In December of that year, a friend of her came to visit and she stayed for a couple of weeks. She was small, her hair reached her shoulders, nice ass, small but nice tits. Obviously my horny ass was looking at her all the time, she used to wear a tiny short where you could see her butt cheeks and no bra whatsoever.

One day we were chilling in the living room (mom was working) and we were in the couch, it was cold so we took a blanket and we fall asleep, when we woke up we started talking and idk why I put my hand on her ass and she didn't stopped me.

Later, I playfully grabbed her phone and ran away, she chased me and we went to my room, we started playing around and suddenly we kissed, she felt bad for a second but then we went back into it, she took her shirt off and I licked her nipples, I went down on her and that was it for that time.

A year later she comes back, I was so excited about it, I couldn't stop thinking about her. The first friday since she got there I waited for my mom to fell asleep and I went to the couch where she was sleeping, I touched her shoulder and she immediately opened the blankets to let me in, we make out, she sucked my dick, I went down on her and finally she put a little bit of saliva on my dick and started riding me.

It was amazing, watching her grabbing her own boobs while riding me, grabbing her ass and just feeling her insides was something else. After that, we fucked in missionary and I finally came on her chest. It was so good that next day while my mom was showering we fucked again in the same couch.

After she left we kept talking on social media, occasionally she would send nudes but the time passed and we no longer talk.
