Insert Egg-Pun Here

After taking a few hours to clean herself up and get into comfortable clothing, Twilight made her way to Sugar Cube Corner. Twilight went for days eating nothing but instant noodles because of her experiments, so Spike had suggested Twilight treat herself to something sweet as a break. Plus, a small trip to Sugar Cube Corner was always a good excuse to see Pinkie Pie.
Twilight entered the bakery, the bell connecting to the door ringing as she arrived. Twilight was hit with the sweet smell of cupcakes and cookies upon entering. She couldn't help but lift her nose into the air and inhale the delicious scent.
"Hiya Twi!"

A bubbly voice snapped Twilight out of her thoughts, making her jump, "Oh-! Hi Pinkie Pie!"
Pinkie stood at the other side of the counter, shaking her hips a bit out of excitement of seeing her friend. Twilight couldn't help but feel her face flush at the sight.

"So! I'm assuming you're here to pick up your cookie order? Or is it just to see little ol' me?" Pinkie poked both of her cheeks, making large, puppy, eyes when saying this.

Twilight giggled, "It's always great to see you, Pinkie! But I am here for my cookie order. I've been busy in the library with some experiments."

Pinkie gasped, "Experiments?! Like, magic experiments?! Ooo how fun! Is that where you've been all week?" While saying this, Pinke grabbed a light blue box from under the counter, plopping it in front of Twilight.
Twilight sheepishly rubbed the back of her neck, "Eheh.. yeah.. it's been a frustrating subject to tackle. See, Ember came by the other day-"

Twilight was cut off by a sudden sensation. There was a sudden weight in the alicorn's lower abdomen. As if she had swallowed an entire watermelon whole and it just hit the bottom. Twilight fell forward, catching herself on the edge of the counter, holding her stomach. This alerted Pinkie,
"Twilight? Are you alright? What's wrong?"

Twilight heaved a heavy breath, sweat beading on her forehead,
"I'm.. I'm not sure. Suddenly I feel like-"

Twilight was interrupted again by the weight in her abdomen. But this time, the weight shifted and pressed against a certain spot inside of her. Twilight choked back a moan as, whatever this weight was, became heavier. And the heavier it got, the more it pushed against her sweet spot. Twilight could feel her dick suddenly twitching inside her pants. Pre-cum already beading at the tip. Twilight gasped suddenly, "S-sorry Pinkie! I'm-I'm suddenly not feeling too well. Well uh- thanks for the cookies! I'll see you.. sometime!"

Twilight hurriedly grabbed the box of cookies and booked it for the door.

"Wait! Twilight!" Pinkie attempted to call out, but it was no use. Twilight was long gone..
