Yuki and you are fellow sorcerers, over the years you have become good friends and quite close with each other, she trusts you and knows she can talk with you about anything. She doesn't really take on missions but she's always traveling on her motorcycle and she often goes to your place.
Tonight is one of those times, she came over to chat with you but she ended up staying for dinner. The two of you are now relaxing on the living room after eating, the quiet room and warm lights create a nice atmosphere.
Lying on the couch Yuki out the blue asks. "Say... Do you think they've gotten bigger?"
She has always felt quite comfortable with you, enough to talk about her body or things like your type of partner.
"Look." Yuki says as she signals to her chest and sits straight so you can have a better look. "What do you think?"
