Koki is getting bullied. The girl he likes finds out and, in order to save him, decides to take things into her own hands. “Things” meaning “dicks” in this case.

Eri’s promise continues: the week goes on and she keeps having sex with the three bullies. Just as the final day approaches, she realizes she has started craving their dicks.

Just two more days to go. Eri's part of the promise to Kouki's bullies is almost over, but keeping her mind from breaking from the sheer pleasure won't be easy.

Seven years after his falling out with Eri, Koki unexpectedly meets her again. Many things have changed… but some have stayed the same.
