Big Breast of Northern Duke

Calix Winter.

A northern grand duke of southern origin with bronzed skin. Because of his complex, he has never shown his bare breasts to others, and thanks to that, he is still a virgin.

He is obsessed with chest exercises because he thinks that if he grows his chest muscles, his indented nipples will come out, but he has only become big breasts.

Emilia.

Northern-born with fair skin. She is the new maid at Winter Castle. She has a lot of motivation. She is always ahead of the action, but she only makes accidents.

As befits a native of the rugged northern country, her stamina is better than her looks.
