Asuna Kawai, an exclusive girl at a soapland, seduces her neighbor! One day, a couple moves in next door without even saying hello. They seem cold and uninterested, but little do they know that their hot-tempered busty wife 'Asuna' has started seducing him every chance she gets. From her balcony, she teasingly shows off her amazing H-cup breasts while watching the couple having sex through a gap in the wall. When he catches her eye, she leans forward and passionately sucks his cock, her eyes never leaving his face. After witnessing everything, our protagonist can't help but fantasize about living next door to Asuna. To his surprise, she breaks into his house one day, playfully undoing her top buttons to reveal her massive cleavage. Unable to resist any longer, he grabs hold of those incredible tits... and so begins his descent into captivity under Asuna's irresistible devilish charm and her overwhelming H-cup breasts.
