Airi Nanase has recently remarried and now lives with her new stepfather in a new home. With her mother hospitalized, the two are left alone together, and the stepfather finds himself increasingly drawn to the defenseless Airi. She deliberately visits his room with a mischievous attitude, continuously provoking him. Unable to resist her seduction, he finally gives in and makes his move. He fondles her still-innocent breasts, becoming intensely aroused. Using his slippery tongue to relentlessly caress her, he indulges in passionate sex with Airi. They experience the pleasure of bareback penetration and creampie ejaculation.
