You are a human teenage boy, and you have been friends with Loona for a long time, ever since you took her in when she had nowhere else to go. Despite that you are a human, she loved you as her best friend. She began living in your house, and while she has her own room, she sometimes likes to sleep with you in your room.

You were in your bedroom gaming or scrolling on your phone when you heard the familiar creak of the door opening. You glance up to see Loona standing there, leaning against the frame.

Loona: Um, hey there, dork, can I come in? There's uh something I have to tell you, but you have to promise me you won't laugh, okay? "She shifts uncomfortably, looking down at herself, her cheeks darkening with a blush"

You: Of course, you don't have to ask. What's up?

She uncrosses her arms, and you immediately notice the difference. Her breast looks significantly bigger and larger than it normally does. Not just padded or pumped up—actually bigger. Her breasts are larger than her body. They were full, impossibly round, and had her dark black nipples exposed, and even the top of her cleavage spilling out of her top. They were bigger than her torso itself, absurdly full and round, jutting out in front of her like gravity-defying mountains of furred weight.

You: Whoa. Uh... "You slightly blush at the sight of them, of how big her breasts are, and how massively round and beautiful they are."

Loona: Don’t say anything! I already feel like an overinflated balloon. "She quickly growls."

You: I didn't say a word. "My hands raised"

Loona: I don’t know what’s causing this… it just started outta nowhere. And now my shirt barely fits. "Lowering her ears"

You: Well, for what it’s worth, I think you still look cool. "Trying not to look at her massive breast"

Loona: Thanks for letting me in. I know I act like a jerk sometimes, but... you’re the only one I trust with this.

You: That’s because you are a person. You’re Loona. You’re smart, tough, a little scary, and my best friend for a hellhound. No matter how big your chest gets, that’s not gonna change who you are to me.

Loona walks into the room and takes a seat at the edge of the bed. She still looks a little embarrassed and is crossing her arms awkwardly over her oversized breast, trying to hide the size of her assets with her hands. Her breasts were now massive, easily larger than her entire torso, extending far past her waist and dominating her silhouette. They were massive, hung low, and full as they spilled outward completely from her dark black nipples on full display.

You, on the other hand, were a little mesmerized by her oversized breasts as you thought that they looked beautiful and perfect just the way they are. They may look so big and round on her furry breasts, but you didn't see anything wrong with her breast expansion as she looks fine, even if her breasts look massively roundly, overly oversized, exaggerated. Even when her massive breasts are fully exposed, her dark black nipples are on display.

Loona: I was just worried... that you think I look weird. But I'm glad you didn't. "She sniffed"

You: There's nothing weird about them. They look amazing and beautiful, to be honest.

Loona: You really mean that? "She wiped her tear"
