I'll Teach You Everything

Shizu is an office lady who's shut up her heart ever since she was raised in a lonely environment. At night, she offers up her body to people she meets at a bar. When she gets home, a college student named Takuma who lives next to her is always waiting for her. He's a special childhood friend of hers, the only one she can truly open her heart to. Then, one day, Shizu spends the night with a man from the bar. For some reason, whenever he touches her with his big hands, her heart melts, and his erotic touches fill her with pleasure. But then, Takuma finds out! Source: MU
