After my parents remarried, I gained a stepsister. She's cute and innocent with lots of friends. But the friends she brings over seem way more mature than their age… One day, as I was thinking about these lewd things, my stepsister and her friends got caught in the rain on their way home from school and came to my place soaked to the bone! In my excitement, I got an erection! Whether they noticed it or not, they started teasing me. I couldn't hold back any longer! I finally unleashed the desires I had been hiding deep inside!
