GRMR-075 is developed by a pair of voyeur boyfriends and awakens the pleasurable feeling of etching.

A seemingly innocent college couple, so naive it's hard to imagine them making love. She appears to be new to dating, displaying a shyness akin to entering a man's room for the first time. Her boyfriend gently guides her, who seems inexperienced, while she, an innocent girlfriend, is led by overly polite caresses, gradually melting into pleasure as she awakens. These two lovely people are driven mad by it all.
