She feeds her the next piece and pats her head.

"Good girl for focusing on your food."

She smiles and blushes as she chomps down on the next piece. She really wants to be uncuffed so she can touch Mara but she'll wait to tell that until after she's done because she is a good girl.

Mara finishes feeding Katie in short order! She rubs her tummy afterwards.

"As I was saying, of course you'd finish your food faster than me, you fucking cow. I'm gonna need lots of dedicated training before I can develop nearly as bottomless of an appetite as you."

"Cow? Please, I'd never be a prey animal. I'd say I'm a bear, if the gay men hadn't already claimed a monopoly on that."

"You're so based. Can you assign me a fursona?"

"A housecat, perhaps? A predator, with the corresponding instincts and energy, but still best off under the care of another.

...heh. Maybe someday I could post you on r slash chonkers."

"Plus size petplay subreddit, call that r/chonkersgonewild. Seriously though, correct choice. You understand me so well for a woman I just met."

"The soulgaze will do that! It's one of the great perks of being a wizard. Almost makes it worth having to learn to clone a hard drive."

"Anyways, I was gonna say this earlier but was too busy eating, but I literally have trouble sleeping on my stomach because my ribs poke into the bed. Just wanted to get across the urgency of you fixing me."

"SAD!" she says in a poor but recognizable attempt at a Donald Trump voice.

"Healthy young warlock gets busted, kidnapped by sexy wizard domme, feels good and changes - BBW! Many such cases!"

Mara laughs.

"You have an adorable laugh. Can you uncuff me so I can grab your boobs now?"

"The cuffs are there for a reason, sweetie! If you swear to not use magic against me and not leave the property without my permission, I can take them off. If you haven't thought about it and concluded you're okay swearing that and are acting out of impulse because you want to touch my boobs that bad, you could swear it for the night and I could put the cuffs back on in the morning."

"Okay. I swear not to use magic against you or leave your property without permission until the next sunrise. I'm a little worried about this being manipulated into remaining in effect indefinitely, either by you or by the cruel whims of fate, but if the earth stops spinning that's the least of my problems."

"Well, the idea is in fact to keep you within my power in one way or another long enough to verify you aren't going to revert to using dark magic and become a warlock! But yes, the cuffs can come off now."

She removes them.

"Well it'd be no fun if I didn't at least make some effort to resist, would it?" Her newly freed hands start just above Mara's crotch, slowly working their way up her belly and towards her tits.

Mara smiles.

"Very true."

She makes more and more pleased noises as Katie's hands approach her tits.

As her hands reach the tits, she squeezes onto them and circles her thumbs around the area where she estimates the nipples to be. "God, these really are lovely. I hope mine get to be this big."

She has correctly located the nipples! This elicits louder pleased noises.

"They will be, darling. If nothing else—mm—we could make it one of your magic projects. Modifying your own body is—nng—perfectly legitimate."

"Ooh, hey, can you use magic to make me gain weight faster too?" She moves her hands down to Mara's underboob and plants her face in her cleavage, careful to keep her ears exposed so she can hear.

Mara places a hand on the back of Katie's head, holding her in her cleavage.

"Yes, that could be an early project. A potion to enhance metabolism."

Katie wants to keep discussing their magic plans but is nonetheless grateful to be in her current predicament. Her hands blindly fumble their way back down Mara's vast expanse of body, squeezing her squishy love handles (they're called that for a reason!) on their way to her thighs.

Touching Mara's thighs produces a moan! She also adjusts Katie's head, pushing her mouth towards one of her nipples.
