Caught by my mom.... For the first time

This happened when I was about 16 or 17. The first time that I was caught by my mom while masturbating. I was still in highschool and it was almost the end of the year, in Costa Rica the school calendar is done with the year calendar, so the end of the school year is November - December, unlike in the US where it is May - June. In order for me to graduate highschool I had to pass the year with my school grades and in addition I had to take the final tests that are administered by our Department of Education. Needless to say, this was a very stressful time as back then it was the biggest task that one could have, so not only did I masturbate because I wanted to but also I needed to.

I was in that age where I could masturbate 5 or 6 times a day, everyday, and a week away from the final exams the stress level was through the roof, therefore masturbating would relief a lot of pressure. One day after highschool, we were allowed to leave early so we could be at home studying, so when I got home I was not alone, my mom was there. My parents house, a one story house with 3 bedrooms and two bathrooms, had a backyard and my window was looking at that backyard where my mom would spend some time either with plants or arranging house stuff. This day that I left school early I went into my room after letting my mom know that I was home and closed my bedroom door so I could masturbate. I changed my uniform into regular clothes, which back then only meant a shirt and my boxer shorts. I turned my computer on and went straight into pornhub, to begin my ritual. I started watching a video of a girl masturbating, and after getting a huge erection I started to masturbate, I lowered my underwear not to my ankles but just enough for me to be able to touch myself and still be able to cover up if my mom came through the door.

While watching the video and touching myself I was having a great time, the volume was not too loud but I was able to hear her moaning as she masturbated and I left a few moans out myself, enjoying what I was doing and relaxing before studying for the tests. While I was doing so I saw something move through my window and looked that way and saw my mom, who must have heard the computer, and noticed that she saw me in full when she came to my window. As I tried to cover up by pulling my underwear up, but it was in fact too late. I heard my mom laugh a bit and then say "sorry I heard something and thought maybe you were in pain but what I heard was not pain but pleasure, keep going you need some release of stress" and then left from my window.

At the time I felt mortified for a few minutes, even not willing to continue, however my boner was not only still there, but now it felt harder for some reason, as I was not aware back then, getting caught or having someone watch while you are in pleasure happens to be a huge turn on. I kept going and actually had a great orgasm, enjoyed quite a lot and had a good clean to take care of and then it was time to go outside to "face the music". As I left my room still in my underwear and shirt, my mom already used to me walking around like that, I saw her in the living room where she just said "I hope you had a good time, sorry about the interruption. I though there something off, when in fact it was ON all the way"... I tried to mention that I was sorry, but she was very understanding and very friendly in the fact that it was stressful time with the tests coming up and my age that it was natural that I would masturbate a lot, and as she also said "it is the first time that I see you masturbating, but I do the laundry in this house and I know that you do it and quite a few times a day based on your underwear"... As embarrassed as I might have been after she said that, I also started to get a bit hard as it was quite a turn on to know that someone else knew that I masturbate.

I was about to go back to my room and begin studying when she said "I have also woken you up in the morning and most of the times I can notice some excitement in your boxer shorts"..... I went back into my room not to study but to masturbate once more as it was quite difficult to concentrate now knowing that she knew I masturbate and she has seen me hard before. Passed the tests and graduated and kept on masturbating, with a few more times getting caught by my mom, but you'll read about those in the future.
