In the bathroom filled with the scent of soap and shampoo, Ryota was obsessed with peeping on his mother Ayaka's bath. Guilt and desire swirled inside him. Tempted by the fragrance of his mother's skin, he struggled between reason and impulse. Then, Ayaka suddenly said, "Do you want to come in together? Come on in," shaking Ryota's resolve. He still believed it was childish affection and playfulness, yet deep down, he realized his own desires were exposed. When Ryota appeared in the bathroom, he could no longer suppress his urges and his cock grew hard.
