Hetalia dj - Kawaisou na Yoru no Tori

Pairing: US x UK From [paper_poem](https://www.mangaupdates.com/groups.html?id=11628): England accidentally summons America's demonic doppelganger; naturally, their "contract" can't be sealed with a handshake - it has to be sex! Somehow, these bargaining terms don't go over well with the *other* parties involved.
