Mi prima dormida

Okay basically it's a story from a few years ago when I was a teenager and had my hormones in full swing, I had a cousin of the same age who came to visit my sister and stayed for a few days, the thing is that I got really hot, one night they asked me to lend them my charger and I lent it to them, then around 2 am I went to get it from my sister's room (it was summer) and there they were both sleeping in bed, immediately my gaze fell on my cousin who had on a tight tank top and very short shorts, I got really hard right away, extremely excited, I started touching myself over my shorts and was really hard, I was nervous because one of the two might wake up but at the same time I had an excuse with the charger, then the excitement won out and I took out my phone and started recording her bum with that super tight short from different angles while slowly pulling it down and then quickly, I had a strong urge to put my face in the middle of that beautiful bum but I restrained myself and just kept recording, every now and then I'd bring my penis close to her butt and rub it slowly over her shorts, like that for about a minute until I couldn't take it anymore and came in my boxers, I would have loved to finish in her tiny ass but it was very risky, that video got me a lot of cum over time, until one day I felt guilty and deleted it, has anyone else had a similar experience?
