One day, when Shota comes home, he finds his photographer dad taking pictures of nude model Miina! Shota is smitten by Miina's huge tits swaying in front of him! He sneaks around while his dad isn't looking and plays all sorts of pranks on Miina! It starts with nude sketching, then he rubs her bare tits, gives her a titjob in a mixed bath, and has a blowjob and sleepover sex! The plump and well-endowed Miina cums over and over again with the intense pistoning of his dick!
