Bun-O, a college student, can't get Mizue, the voluptuous and busty married woman living next door, out of his mind. He spends his days in a daze, indulging in various fantasies about her ample breasts and almost bursting buttocks. However, Mizue had long been aware of his fixation... One day, to deliver a souvenir, he goes to Mizue's house. Noticing Bun-O, who is spellbound by her cleavage, Mizue gently envelops him with her kindness. His groin is on the verge of exploding with longing for the aunt he adores... The dream S●X with the ultimate squishy, mature woman, whose touch is the best.
