Lewd Cultural Exchange ~ The Fall of a Graceful Married Woman to NTR!

"Um, um... Nice to meet you... I'm Daikel Bimango. Please be kind to me!" Today, a new student from another country came to our house. Since we can't have kids, we've been hosting students for a few years now. This time, it's a young man from a tribe called "Dicon." Spoiler "Mizuki, do you need help with anything else?" Despite looking tough, he's a nice guy who studies hard and cares about others. He's been learning our language and talking to us without any problems. But then, something strange happens. No matter how many times we knock, there's no answer from inside. "...Hey! Hey! Hey! Hey!" Instead, there's a loud roar like an animal coming from the room. (I hope everything's okay... Maybe he's having a fit...?) Feeling bad but worried, I try to go into the room, but there's still no answer— (Translated from DLsite)
