Tsun M! 2 – My Girlfriend is a Cute Pet

Synopsis

Nemu, your cousin and girlfriend, shows up at your door after running away from home. With your parents’ blessing, you naturally end up taking her in. However, there’s one condition: you must maintain a platonic relationship until she graduates.

One day, you head to the convenience store for supplies, and Nemu refuses to come along, clearly upset. When you return, she gives you a cold stare without saying a word. Then you notice it—an adult magazine your coworker lent you, filled with explicit SM content featuring women in collars, chains, and rope bondage.

“Is it because… you have these kinds of interests that you won’t do anything with me? Because I can only do normal sex with you…?”

Before you can respond, Nemu rummages through her bag and suddenly holds out a collar.

“Hurry! Come on, put it on me! Put this collar on my neck! I don’t want to or anything…! Hurry! Put it on me… big brother, please! Like the woman in this book, put the collar on me!”

So begins the story of Kentaro and Nemu’s days together—with a collar.
