If you read it he’s an robot that was built to look like him sooo it’s not le twincest it’s doppelgänger sest
I know but what really fucking creeped me out was the line “his cock is the same as mine” AND HIS UNCLE BUILT THAT ROBOT, HOW WOULD HE KNOW WHAT HIS NEPHEWS COCK LOOKS LIKE, ALSO uhm, why did the uncle say “consider it a loving punishment” when he quite literally becomes a sadist, NOW THAT IS ALL CONSIDERED INCEST ( that uncle creepy af )
This is a seems legit manga
