Mitsuki, the girlfriend, decides to take on a part-time job as a nude model in order to go on a trip abroad. "He said I'd only have to take off my clothes a little...! It'll be fine! Don't worry!" she tells her boyfriend, but... Her nipples are rock hard as an artist with a deep understanding of the female body kneads her breasts. Oil creampie sex brings her divine J-cup body to orgasm over and over again. Though she says no, her body learns the pleasure of sex with this artistic old man, something her boyfriend doesn't... This is the whole story of a cuckold video where she exposes her slutty face as she is penetrated repeatedly and creampied before her boyfriend, succumbing to the pleasure.
