Heart to a gem

Mirrors and Rarity were walking to Sugarcube corner for a few sweets before working, through Rarity could cut back on the sugar (mainly chocolate)as they were going to her hips but what was different than what would happen to other ponies was that her butt formed a heart-shape with her cutie marks slightly curved. Mirrors thought of it like a ripe fruit with two plump round cheeks. Mirrors was behind Rarity watching the her sway those bountiful behind, ripple like the surface of a pond when a rock is thrown into it.

"How have you been, darling." She asked him not looking behind her even though that would be impossible as her hips were wider than her waist. Clearly his throat he spoke.

"Not much really but Twilight has been acting weird when I'm around her." He said trying to avoid eye contact with the sway of her big, jiggling behind with every step.

"Oh I'm sure she just not used to having a kind, helpful, and very handsome stallion." She said with abit of sultry in her voice. Blushing, he smiled that the princess of magic was interest in him. Out of all stallions in Equestria, she had a liking for him. He always thought that She and Big Mac would be a thing but it seems not.

Before he could think more on the subject, he walked face first into Rarity’s rump as she stopped in her tracks. His muzzle was momentarily buried in soft flesh, it gave way like a marshmallow.

walked into Rarity's shop, the dressmaker's plump posterior pressed against the paneled floor like two soft cushions under some heavy weight, pouring out over the floor like cookie dough.
