107SDJS-269 Honda Sora prefers tweaking nipples over PC for 3 days SOD female employee carefully studies nipple tweaking SOD sex science lab report 18.5

At the request of SOD Sex Science Lab, Honoka Motoda conducts an experiment to verify the linked sensitivity of male nipples and penises. She tries various stimuli such as rolling, pinching, kneading, licking, and sucking, and confirms the erection response with her eyes, mouth, and vagina. Recently, there have been no private affairs, but I will send you the research records of an AP from the production department who unconsciously touches his nipples to make his penis sensitive.
