Natsuki Aozora, a sweet and innocent-looking coed, and her friends take it upon themselves to help their shy, virgin classmate, Taro, learn the ropes of sex. They start with Natsuki gently licking and sucking Taro's stiffening cock, her fingers tracing the outline of his balls. The other girls join in, their soft hands guiding Taro's eager hips as they teach him the art of grinding against wet, eager pussies. Despite their best intentions to keep it at teasing and practice, Taro's raging hormones and the girls' own desires lead them down a path of no return. Taro's thick, pulsating dick soon finds its way deep inside Natsuki's tight, slippery cunt, and he fucks her hard and fast, just like the girls had taught him.
