Four salaried men, working for low wages, share a small rented room. Since some of them are married, this place has become a popular secret spot for paid encounters. A third-year female student from Komatsu University, wearing glasses. Ever since entering college, she's had no boyfriend, and seems quite inexperienced and shy about sex. The office workers quickly pick up on her timid cries. Making full use of their secret base, they set out to thoroughly satisfy her. Though she looks like a plain, quiet girl with glasses, once undressed, her body is surprisingly voluptuous—her breasts are slightly large, with charming pink nipples. The tight space ironically creates an intimate atmosphere, drawing them closer together.
