When I was secretly smoking a cigarette in the garbage dump of the apartment building, I was reading a porn magazine that was thrown away by a sexy lady with a big ass who always shows her miniskirt and panties on the stairs. She noticed me staring at her big ass and said, "Auntie, I'm feeling horny. You're the girl who always peeks into my panties on the stairs, aren't you?" and invited me to her house. Her big ass got on my crotch and I was so excited that I was going crazy. The lady taught me how to have sex with a woman in a very polite and naughty way. I never knew that having sex and ejaculating felt so good.
