“Oooof.” Twilight moaned as she reclined on her bed. She rubbed small circles on her taut belly, cooing as the dull ache began to fade. ‘No wonder Princess Celestia avoids the press. All this cake went to my new royal hips.” Twilight giggled as she spotted you eyeing her from your post. “Guard….what do YOU think?” She smiled as she turned onto her stomach and pushed her fat ass in the air.
 
A bead of sweat rolled down your face as you absorbed the image of Twilight’s rear. It bounced just slightly as she wiggled her rump, leading down to her full, round tummy, “My…My feelings only grow for the new Princess. She should behave how she desires.” You gulp as she turns around, eyeing you with a dominant lust. “Such a polite way to say I have a nice, fat ass. C’mere you stud!” Twilight grinned as she grabbed you via magic and slammed you on the bed.
 
Your armor was gone in an instant, leaving you nude on the bed. Twilight moaned as she caught the sight of your erect cock just waiting for her. “Maybe a little reverse cowpony so you can see just what you’re in for?” Twilight grins as she turns around and practically shoves her ass right on your nose. Her incredible purple mass pulls away before slamming on your cock. You both moan simultaneously as her anus clamps down on your rod. Without missing a beat, Twilight raises herself up and slams back down, her booty slapping against your torso. Again and again she pumps her hips, working her round curves to and fro. You grab her hips and thrust upwards, sending a few ropes of cum right in her rear.
 
“Oh I hope you have more than that. I’ve got to work off these calories.” Twilight grins as she spins around. Every hole, every angle, all night long until you’re both sweaty, drained and passed out in each others arms.

LOL at ‘implied belly rubs’

Dammit Twilight, you’re supposed to show a little restraint!

She seems to be following in Celestia’s hoofsteps, and I’m glad she is. Perhaps we’ll have a royal tummy rubbing assembly.

I hope all the cake stays in her beautiful royal belly. She needs to make it even bigger.

I give myself permission to… serve her what she wants.

I must give rubs to the royal belly.  
rubs her highness’ belly

Dat belly.
 
It demands rubs.

Let them eat cake!

Judging by her expression she wants a lot more than snuggling.

Permission to snuggle the royal tummy?

Beat me to it
