Kaede and Her Sugar Daddy
Kaede enjoyed her island trip with her boyfriend. And they had great sex... or at least she thought they would. Sex with her boyfriend feels bland and unpassionate. She hadn't planned on seeing her sugar daddy again, but her sexual frustration knows no end. Kaede decides to continue their relationship, but then her sugar daddy says... "Wanna be lovers?" He says many things that make her think. She decides to talk to her best friend, Miho. Miho ends up telling her the same thing as her sugar daddy. In the end, she's told to cut it off. Even with all her worries, she's unable to overcome her body's desires... Things are going well for Miho, so I should be fine, too, right...? She tells herself this and ends up giving in. Then, with immense sexual desire, she falls even deeper.
@ChronicLogic, it could be a case of crab mentality. People with bad habits often want others around them to partake in the same bad habits as they do, so that they can feel less guilty about those habits. It's weird logic, but just look at how some fat people try to shame family members who want to lose weight etc.
