Iroha Narumiya is a widow who runs a bar with her stepson. One day, she is excited by the gazes of customers who only stare at her chest, so she goes to her house and gives them a handjob... and seeing the satisfied customers, she starts a "home drinking service". She goes to the home of a masochistic man who has injured his leg and teases his nipples, slaps his dick, and crushes his balls, satisfying the customer's sexual desires with pleasure! When she turns the handsome company president over, she licks his ass and gives him a superb blowjob, making him cum in her mouth! She gets into a fight with her son over work, but she swallows her son's dick deep in her throat and makes up for it with an incestuous anal licking session!
