This is the first time we've seen the two of them together, and it's clear that they're having an affair. We learn that saki and keisuke have been using large packages of condoms, which means that everyone in the company knows that they have been having sex with each other. This is a big deal, and saki wants to know why he's being so bold with his choice of sex partners. He tries to get saki to stop using the condoms, but saki doesn't want to listen to him. He's also worried about the fact that everyone will know that he has had sex with saki. saki tries to convince saki not to use the condoms anymore, but he can't get him to stop. He tells saki that he'll have sex with him, too, but that he won't be able to enjoy the sex if he'd let it get away from him, even if he was full of food. Aww, saki, you're right. I'm not the type to let a good meal get away, even when I am full .
