In Mito city, we met a slender native girl with a sleek, flexible body. Her mature facial features contrast with her sweet, clingy personality and adorable voice. She's cheerful, fun to talk to, and works part-time as an English private tutor—having a bright, energetic teacher like her would definitely make studying enjoyable. But today, instead of English lessons, we're doing a different kind of "studying." I quickly have her take off her frilly dress and remove her underwear, and she happily undresses for me. When I ask her to masturbate, her smiling face gradually shifts into a sexy expression. Using just her hands isn't enough—she actively rubs her pussy with a vibrator, her body twitching and jumping as she gives off incredibly erotic reactions. Women who are easygoing in daily life really do get fully into sex too. Since I need to study ○○-chan's erogenous zones, I immediately press the vibrator against her pussy while stirring inside with my fingers, making her squirt a huge amount of fluid. My techniques aren't limited to this—relentlessly and intensely rubbing her pussy, her body violently jerks as she orgasms. My cock is now rock hard, so it's time for ○○-chan to serve me. When I present it in front of her, she gently strokes it and carefully takes it into her mouth. Could it be from being a tutor? Her tender actions feel incredibly good. Thank you. The final lesson, of course, is penetration. From behind, I thrust into her again and again with intense force, and the occasional glance she gives me makes my heart race. The student doing something naughty with his teacher... feels so good!! I absolutely love sex lessons, and I want to try even more positions!!
