Uh-oh! My twin sisters are failing their classes!

As a teacher at their school, I feel obligated to help them study, but these two girls have no intention of applying themselves.

I've managed to get them to agree to study sessions in exchange for pampering them, but now they're saying they’ve realized their true feelings for me and are starting to fight over me! What's going on?

Being a big brother to two cute but headstrong girls was already hard enough without adding this to the mix...!

Come explore the depths of forbidden familial love with Chinkamo Twins, a story about two twin sisters who love their Onii-chan a little too much!
