Suzu is a big-breasted office worker they picked up on the street. Her quiet appearance and conspicuous breasts made them approach her, and because she was inexperienced with being hit on, they pressured her into drinks, got her drunk, and managed to have sex. After that first fuck, they exploited her inability to say no, barged into her apartment whenever they wanted, turned her into an always-available fuck buddy, and began using her together with their friends.
