Input: Text: quick backstory first. i'm 15 and i feel like i need to masturbate at least 3 times a day, so i do it as much as possible and mostly when i'm left home alone.

today my mom went to work, so i was home alone and was eager to get to my dirty little secret. and when i got to it, i was in the living room because i was "home alone" closed my eyes and fantasized about my crush, and began as soon as i was hard on. it usually takes me about 15 minutes, and when that mark hit, it was the same time my sister walks into the living room, and she saw me cum.
