My big brother-loving little sister came into the bath... She's starting to look a little more grown-up, but I thought she was still a kid, and then she suddenly started to give off an erotic vibe and started to kiss me like an adult would. "Big brother... is this your first time? I'll teach you all the cute naughty things." I took his virginity with a deep kiss and sex... Without telling my parents, I thrust into the depths of her vagina over and over again and came inside her over and over again!
