There to help with a demonstration at work, Airi Mashiro finds herself naked and demonstrating what its like to service a group of guys. They suck on her tits, lick her ass, and finger her until she squirts. The guys pull out their dicks and rub them on her back in her armpit, all over her face and eventually she gets to suck them all off. They take turns pushing their cocks into her shaven pussy as she slurps on someone else's dick. They fuck her on the floor, on the couch, standing up and they fuck her upside down. Then they take turns leaving a creampie in her snatch.
