I had sex with a student, she doesn 't remember because she was drunk, but i know she liked him

I work in front of a school and always i see her coming and going with her friends, so beautiful, so sexy ... i could only think of the pleasure to see her naked, that round ass and my cock in and out of his body. it was like a dream, at night i would masturbate thinking about her, and i left my work day to watch her go by for a while. i had never been in the bar, but one night was a friend's birthday and i agree, i had no idea she would be in the same bar. she was with her friends, like at school, so i went and offered them something to drink. he was an alcoholic drink, and strong. then i bought them another, and another. i asked the bartender to put them in double measure of alcochol and a lot of sugar, so that they did not realize. when his friends went to the bathroom to throw up, i pulled him out of the bar without anyone noticing. i took her to the hangar where i work and took her on a mattress on the floor. after that i left her at the school gate. i think she doesn't remember anything of what happened, but i have a video to masturbate every night.
