At the request of SOD Sex Science Lab, Sora Honda conducts a demonstration experiment on the sensitivity linkage between male nipples and penises. She tries various stimuli such as rolling, pinching, kneading, licking, and sucking, and checks the reaction of the penis with her eyes, mouth, and vagina. Although she has not had any private affairs recently, she unconsciously touches her nipples to make her penis more sensitive.
