Dirty Tina, the renowned toy seller, invites Miki Mei for a private product demonstration, but the real fun begins when Tina decides to try out a new anal dildo on herself. Miki watches, entranced, as Tina lubes up and slowly inserts the toy, her moans filling the room. Tina then turns the tables, pushing Miki onto her hands and knees, and proceeds to lick her pussy from behind, making Miki squirm with pleasure. Tina's skilled tongue brings Miki to the brink, but she's not done yet. She switches to a doggystyle position, pushing the dildo deep into her ass while Miki watches, eager to join in the fun.
