Tenso-sama's Secret Base

Bat-like woman Tenso lives in a prefab house beside the long-empty Forest Mansion. She seduces the visiting human boy Aesong and has him perform oral sex. She praises his erection, then spreads her legs for anal insertion. He slowly penetrates and thrusts to climax and ejaculation. She receives and swallows the semen and warns him to keep the secret.
