Dash was about to score an academy record today: 3 mares banged at once. She was proud of that fact, and she proceeded to promise her friends all day that she had something extra special planned for them. Starlight tried not to wonder too much about it, she would find out soon enough anyways. She just knew that it would be amazing.

Well, it was something all right. After Starlight had been bound to the wall in between Pinkie and Twilight, she soon found herself decked in foal gear, from bibs to diapers to a pacifier in place of a gag. Pinkie was dressed similarly; however, Twilight for some strange reason was normal as ever. Before Starlight had time to wonder why, Dash started.

"Tonight we shall initiate the newest member of our family."

Starlight and Pinkie shared a glance. This was it.

"Twilight and I will take care of you as much as we have Pinkie, under the condition that you pretend to be very young. I'm sure you have realized that by now," Dash continued.

Pinkie spit her pacifier out briefly. "Are you gonna do the same thing to Starlight that you did to me?" She put on a surprisingly accurate baby accent before sticking her tongue out Yoshi-style to retrieve her pacifier.

As expected, Dash bucked Pinkie in the abdomen and her diaper immediately darkened. Pinkie smiled adorably while Dash facehoofed. "I'll change you later, young'un," she rolled her eyes. "But yes, Starlight, I will be doing the same thing to you. You ready, Twilight?"

"Yes sir," Twilight flashed her horn (which was free for some reason) and then roughly pulled Starlight's face into her nipples.

Starlight soon realized what was going on. Twilight had conjured magical breastmilk and was now feeding it to Starlight. It appeared that Twilight was the mother in this relationship, and Dash was the father. Was that how they fell in love in the first place?

Starlight continued to gulp the bland-tasting liquid as she smelled fresh urine. She guessed that Dash was changing Pinkie at this point. Soon enough, she felt a rough hoof (probably Dash's) shove her farther into Twilight's nipple.

After a while, Dash yanked her back up, and before Starlight could think, Dash was inside her once again. Obviously watching Twilight breastfeed Starlight had turned her on immensely, and she was making the most of it. She also penetrated Twilight and Pinkie before they were done.

As Dash walked Starlight and Pinkie to bed, Dash explained the plan for the next day. "So tomorrow you two will wear diapers under your swimsuits, and act like toddlers. Also, if your diapers are dry by the end of tomorrow you'll get a reward."

That sounds good enough, Starlight decided as she let Dash tuck her in.
