Desperately grope at her gigantic tree trunk thighs, to start.

"Aww, my little sushi roll, are you about to fall over down there?"

She might be, but her mouth is too busy to answer. Hands move up to Mo's love handles.

"Mmmm, bear a little left, sugar cookie."

Katie isn't sure whether she means with her hands or her tongue, so she confusedly does both.

"My left." Ear-pinch and a tug.

Fuck. A twinge of... guilt? fear? She's not sure. passes through Katie. She obeys.

"Good, there you - there - mm-hm." She tugs Katie's face away by the ear, though not so pinchily.

"What now, mistress?"

"Boss. If you're going with titles, it's boss."

"Understood, boss."

"Now, plum pudding, you may make a request."

"Well I, I'd been wanting you to fuck me with a strap but I don't know if you have one or anything..."

"Are you going to melt like the froyo you are if I have a goon go fetch?"

"I-I hope not... Maybe you can keep me busy with your fingers until then..."

"I do have to open the door to get anything fetched for me, sweetpea."

"Understood."

Over to the door - it's more of a trapdoor - goes Monoceros. She opens it. "Goon! I want the purple bag from the second drawer in my bathroom."

"Yes boss," comes a faint goon voice from the bottom of the elevator platform shaft.

Katie sits in the corner, keeping her nethers busy with one hand and stimulating a nipple with the other while she waits.

She doesn't have long to wait; Monoceros paces a little and soon the elevator platform comes up with the purple bag on it.

She puts on the requested article and flings Katie to the floor to have at it.

She gets in position as best she can with her overstuffed gut and readies herself.

Monoceros's gear is big enough to extend past her midsection a fair ways.

And she's superstrong and fucks pretty damn hard.

"Ohhhh..... fuck.... your belly on top of me feels so good..."

If Katie can still talk then it's safe to go a little faster.

"Nnnnngggg..... fuck...." Katie's hips gyrate back and forth involuntarily. It feels so good. Feels so right. And it's only gonna get better with every pound she gains.
