//bestiality, Miyacest - - - Atsumu looking for his Gameboy under his and Osamu’s bunk bed and getting stuck, and his struggling and calls for Osamu to come and help him wake up the family dog asleep in the corner.

Atsumu hears him approach, and feels his mouth close around his boxers and thinks he’s free until the dog just pulls his boxers down.

Atsumu is confused until he feels a long, thick tongue between his cheeks licking up Osamu’s cum from earlier, and immediately realises that the dog sees him as bitch because he’s in a standard mating position, and their dog is familiar with being a stud.

Osamu comes in to the room, only to see Atsumu stuck, being rimmed working an inch of his life by the dog, and instead of pulling him away and helping Atsumu, he drops his shorts and sits next to Atsumu’s stuck body, stroking his back and telling him to be a good bitch
