On a company trip to a hot spring inn, a big-breasted office lady becomes the target of her male coworkers. During the banquet, they close in on her as she drinks alcohol, and once in the mixed outdoor bath, harassment escalates rapidly while she grows increasingly drunk. When she calls for help, no one comes to her aid, and her colleagues gradually give in to lewd behavior. With no escape, she's subjected to group breast groping, forced orgasms, and compulsory blowjobs that grow increasingly cruel. Then, a cock is violently forced into her, leading to a relentless back-to-back double penetration. *Facial exposure in main feature.
