Rintarō has a big problem. You and Osamu are starting to get a little annoyed at it. Suna has a major biting problem, especially in bed.

Osamu is making food? Rintarō's behind him biting his neck. Your tryna do laundry? Rintarō's trying to nibble on your earlobe or knuckles.

Rin just loves biting and leaving marks. He can't help it. So when you and Osamu told him to stop doing it, because you both would like to walk in public without having to hide bite marks, he reluctantly agreed. He loves you both, that's why. But, he only lasted about 3 days of this. He hated it.

That's how both you and Osamu woke up in your shared bed, covered in marks all over. Rin got his payback to say the least.

"Say cheese, samu." Rintarō said with a deadpan expression though there was a small smirk present, he was taking a picture of osamu's bare and marked body with the flash on.

Osamu groaned, "shaddup." He uttered out while covering the camera on Rintarō's phone. Osamu's face was very red, even the tips of his ears were tinted with a rosey color.
