"Look at your little tummy all poked out from drinking so much of my milk!" Olivia giggles.
Caitlyn moans softly, "Yeah, I really overdid it this time, but it tastes so good and you make so much of it."
"And it works, your boobs have been growing the whole time, you qualify as HUGE in my book. Don't you want some more?"
"I can't, I feel like I'm going to burst right now, maybe a little while la... HEY! Your boobs are getting bigger too! No fair."
Olivia shrugs, "They can't help it, baby, they get turned on by you and now they're wanting to join in on the fun."
Caitlyn pouts and fondles her lover's massive chest, "So I'm never going to catch up to you."
"I doubt it."
"That's okay, let's just see how big we can get," Caitlyn says, stifling a burp. "Whoops, excuse me."
"Ah ha! Sounds like you just made some more room, and I've got plenty more to give."
