Fantastic Monster Marriage By Gen, Gen

In a distant world where humans and monsters coexist peacefully, there is still much the two groups don’t know about each other. Heading into uncharted territories, humans enter the domains of mermaids, oni, elves, and dragons to learn more about their habits and lifestyles. While their customs differ, body language is universal, and all races love a bit of foreplay! With busty mermaids having their scales toyed with, slender elves having their ears nibbled, and an oni princess being touched in ways they've never dreamed, these unions between humanity and monsters are matches made in heaven!
