"So, this nice little friend...I mean toy...that I know, Miranda Jiggle, decided to celebrate her birthday by holding a public humiliation of torturing pathetic little bugs beneath her big, sexy mare ass. Naturally, I wanted in on that, and you all know who I simply had to capture and punish first! So, the best way to fully show off your complete and utter dominance and destruction over a puny little bug that thinks they're so almighty is for all to see! So a transparent piece of glass is the way to go! Making sure my favorite butt toy is tucked right in the center of my glorious, dazzling rear-end, so both of my cheeks and my crack can work their damage together, I position everyone's favorite princess right in the center of the glass and DAZZLE her by smashing my ass down hard! Thank goodness this glass is the strongest around, or else it could break and things would get rather messy. This allows for the maximum amount of grinding, butt-bouncing, clenching, and thorough mashing. Ah, the sweet, sweet squelching and crunching noises of pitiful Twilight Sparkle's body getting crushed and demolished underneath my perfect ass is, to say the least, breathtaking. I always enjoy feeling her body twitching and squirming and attempting to escape, all while she gets flattened and stretched out nicely underneath my rear. I think it's safe to say that Princess Twilight Sparkle and my dazzling, pristine ass were meant for each other. No ifs, ands or BUTTS about it!"
