"Tsk. Oh, goodness gracious." Twilight looks up again at her mammoth-sized friend. She's only got half of her giant rear in the desk, and already its legs are bending outward, bringing the seat much lower. Huffing and puffing, Rarity lifts herself up and stands over the desk. If she had to guess, Twilight would say Rarity was nearing 500.
"Hey, Rarity," Twilight greets. Breathing heavily, Rarity turns and waves back. But as she did, Twilight noticed how much her arms, breasts, and even her gut jiggled with every slight movement. "Can we talk?"
One awkward conversation later, Twilight's sitting at her desk as Rarity leans close. As glad as she is to have Rarity take the time to listen to her, Twilight wishes her massive friend didn't have to lean in so closely. Rarity's cushioned bosoms are taking up a lot of breathing space. One breast is weighing down the desk, while the other is resting Twilight's lap. Twilight tried her best not to be rude and stare down Rarity's cleavage. I can't believe Rarity hasn't noticed any of this.
"Honestly, darling…" Rarity chuckled, "Why so worried? So, I may have… overindulged a bit during the summer. What's the big deal?."
"You're the big deal." Twilight knew it was time to give some harsh truths, "Rarity… You've grown too big for your desk. Your breasts are larger than my head. And you're about as heavy as a baby whale. Maybe even heavier; you did go to at least three fast food places this morning."
Suddenly, Rarity feels something very familiar. She bounces up to her feet and looks down at her fat marshmallow body. "Oooh, my goodness." Twilight got the immediate sense that something was happening. Did Rarity finally eat too much? Is it gas? Is she sick?
But then, a low, thundering growl gurgled from within her vast stomach. "Oh?" Rarity blushes as presses down on her squishy belly. "I guess all that food wasn't enough to fill me up. What time is lunch?"
"How can you STILL be hungry!? It's barely 10:00!"
"Well, what can I say?" she shrugged, "I should've gone back for seconds."
