This one is really fit

Its incest, omegaverse n 3p.

*chef's kiss* mr. Cocaine with feet is whack and high, but being with mr. Tough-looking crybaby and their mr. Meat makes it so adorable HAHAHA

Too bad it's more of adultery ~ would love the POV of the dark-haired wife with 2 husbands tbh

Omg omg~ "Boyfriends" hits the nail! I'm not fond of on-going series so I might wait it out for "Canis"

Kekeke~ the perversion lewl, it still has that "focusing on one person" rivalry, but the implication that the pervert and the pooch had mucus membrane exchange to the point of having mutual genes is hilarious!

Love the complexity and Towa's perceptiveness. Need more of the brothers tho, cause they just reek guilt and compensation even if Seiji says otherwise.
