Twilight bets the Princesses she can run Equestria better than them. Turning it into a paradise of hyper-sized sex wasn't part of the bet, but it certainly turned out that way...
She breathed in, puffing up her chest. (She didn’t have the most impressive chest - even after becoming an alicorn, she just had a pair of B-cups - but she presented it proudly.) “So I’ve decided I’m going to be in charge from now on.”
“Yeah, I’m not that subtle about it,” laughed Twilight. “I didn’t go in a very subtle direction with my tits, either. What can I say? It feels good to big!”
Hell yeah screw Blueblood
...not that there is anything wrong with a B cup.
Feels good to be big?
