My life as a virgin who has lived my entire life without any contact with women other than my mother has completely changed! From virgin to womanizer in an instant! I moved to Tokyo to study for my entrance exams and moved into a share house, only to find that everyone there is female except me! And they're all super cute and have huge breasts! I was so nervous I was stiff as a board. But they didn't shun me, a nervous virgin, and accepted me, and even helped me lose my virginity! Not only did they help me lose my virginity, but they also gave me sex practice for the future…the best housemates ever! They'll let me have sex with them morning, noon, and night! In this environment, any virgin can become a super womanizer in 3 days! And you'll also acquire tons of techniques!
