Nikku's sister, Natsuna Sasaki, sits on the couch, legs crossed, worrying about her pussy's scent. She calls Nikku over, asking him to apply cream and even lick her. Nikku hesitates, but her pleading eyes convince him. He spreads her legs, his eyes widening as he sees her glistening pussy. He sniffs, then tentatively licks, his tongue tracing her slit. Natsuna moans, pushing his head down, encouraging him to taste more. He obliges, his licks growing bolder, his tongue delving into her wetness, making her squirm and gasp. She grinds on his face, her pussy juices coating his chin, until she cums, her body convulsing with pleasure.
