Non Nonoura, a quiet literary girl with the charm of a beautiful, slender woman, is persistently pursued by a middle-aged man. The man, secretly in love with her, has been watching over her daily life from afar. One day, after witnessing a male student confessing to Nonoura, overwhelming jealousy and anxiety drive him to lose control—he corners her in a private restroom and repeatedly assaults her. After satisfying his desires, he vanishes from her life. Later, however, Nonoura voluntarily comes to his home. Overcome with joy, the man once again claims her pure body, imprinting intense pleasure upon her. Having discovered the ecstasy of sex, Nonoura softly moans with each thrust of the older man's cock, expressing her growing delight. From her fresh, glistening pussy, lewd wet sounds echo continuously as the demure beauty gradually sinks deeper into a sexual swamp, trained by the older man. This passionate, stimulating story captures three intense, silent, sticky, high-moisture sex acts.
