Sexercise

She'll never skip Pussy day ever again, Sex burns a ton of calories after all.
And after all that cake, well, she has a ton of calories to burn, and an itch that needs scratching to boot

It is very important to stretch properly beforehand... there is definitely some stretching going on. ;)

Commish, Requested as a skinny jogger Celestia, and it seems that the regime is working :3
