One night, after a long training session, Rainbow Dash was enjoying a refreshing swim in the private pool she'd bought... But an unexpected visitor arrived and joined in the relaxing experience.

Luna was also exhausted after a long day at work. Rainbow hadn't noticed her voluptuous figure; Luna was a goddess who was undeniably sexy: big breasts, tiny hips, thighs like thunder, and a huge ass.

But the queen of the night also had her eye on the element of harmony. She wasn't bad at all; she was her type. Even for someone who claimed to be athletic, she was very voluptuous and thick in all the right places: huge breasts and a big, soft, bubble butt.

As Rainbow gazed at the princess's breasts, Luna noticed, causing Dash to turn her head in embarrassment. Luna doesn't miss the opportunity and positions herself next to Rainbow Dash, their ample behinds bumping and rubbing together, prompting the princess to tease her a bit about Rainbow Dash's voluptuous curves.

"You're not bad yourself, Dashie~" Luna said, moving closer, to the point of making Rainbow nervous.

"Thanks... I guess," Dash said, turning away.

"I'm serious, our butts are huge... obviously, there's a difference between a mortal like you and a demigoddess like me, but you're not that far off. Maybe if I give you some tips, you'll have the body of a fertility goddess, almost as sexy as me," Luna said flirtatiously, sliding her hand behind Dash.

"Okay...I... I don't know what to say to that, Princess... To be honest, I'm not a fan of my body being so thick... My boobs are in the way, and my sides are so bulging... They almost fired the Wonderbolts studs for being so distracted, if you know what I mean. But maybe you could... GYAAHHH~!" Dash moans, then turns to see Luna's hand grabbing a handful of her left buttock, massaging and squeezing it tightly.

"Don't talk nonsense, loyalty... When you grow up, your body will be like the gods', and when that day comes, you and I will have a talk~"

"Damn... what have I gotten myself into?" Dash said, worried.
