Living alone in Tokyo is too expensive! So I searched for a property that was looking for a roommate and decided to move in! But then... I found out that my roommate was a woman! I've never even had a girlfriend, and now I'm living alone with a woman! This is crazy! Just the smell of a woman's unique scent, which I've never experienced at home, is enough to make me fully erect! And then I see her underwear hanging out to dry indoors! Just this alone makes me want to cum, but once my roommate gets used to me, she starts wandering around the room in her underwear... I'm having a agonizing erection every night. Then, one day, I witness my female roommate masturbating! It seems she's also horny, and when she looks directly at my erection, the situation changes! I'm in a sexy mood... Maybe this life is the best!?
