My mother's best friend is just an old lady. Ryosuke's expectations were pleasantly betrayed. His mother's best friend, Akane, smiles sweetly and reveals her deep cleavage. Her plump, mouth-watering body and her voluptuous thighs peek out from under her skirt as she walks... Ryosuke is fascinated by the stimulating sight no matter where he looks. He wants to see Akane naked, even if only for a moment. Unable to suppress his Kokoro, Ryosuke goes to peek into the bathroom, but by chance his eyes meet Akane's.
