Sunny and Sprout didn't have terribly long to plan anything too exquisite as Izzy was just making a quick trip down to the trash. Barely three minutes later she came back into the room and checked on the two of them modifying the PoneBloks in the playpen.

"And how are my two foals doing? Anypony ready for a snack?" The unicorn asked.

"Yeah, that sounds like a good idea. What do you think, Sprout?" Sunny replied, glancing over to Sprout and giving a wink.

"Sounds yummy!" Sprout told Izzy, smirking over at Sunny for a moment.

"Okie dokie! Apple slices coming right up!" Izzy replied, turning back towards the bedroom door.

The moment her back was turned, Sprout was on his hooves.

"Wrestling match one two three go!" He exclaimed, half-jumping over the playpen gating, and pushing off the top with his back hooves, coming down and landing squarely on Izzy's back, and wrapped his front legs around her neck, giggling playfully as the additional weight sent the unicorn teetering and falling to the floor, as Sunny came out of the playpen towards the two.

"A snack sounds like a great idea, Izzy," Sunny began, walking up in between Izzy's hind legs before kneeling down. "in fact, what if you're the snack?"

Izzy's brief struggles came to a pause when she felt her tail get lifted up, exposing her nethers. Before she got any ideas, Sprout leaned forward and gave one long lick to her horn, from the base to the tip.

That was, after all, Tip #69 in the Surviving Unicorn Attacks survival guide; a wet horn is a harmless horn.

Of course it was complete malarkey, but Izzy couldn't exactly focus on her magic with earth pony tongues on two opposite ends of her body.

This was pretty new territory to Sunny, as she was unable to use her mouth on herself, and she had also never done anything like this with another friend, mare or stallion.

'Nothing ventured, nothing gained,' she thought to herself as she completed her first lick up Izzy's slit. Her diaper crinkled behind her, and she also caught the fresh scent of foal powder from Sprout's diaper which was inches from her snout. Taking a soft breath, she leaned forward again, placing a kiss on Izzy's inner left thigh, and then the right, before brushing her snout against the unicorn's marehood. Each time she felt she was about to lose her nerve, she merely remembered what Izzy had done with her vibrator yesterday and just moments ago before her diaper change as inspiration to continue.

As Sprout continued tasting her horn, Sunny took the opportunity to place her forelegs under Izzy's hindquarters and life her up, a bit of a strain with Sprout's added weight, but the stallion took the hint and placed his hooves on the ground on both sides of the unicorn, allowing Sunny to raise her rump up and gave her considerably easier access to her prize, as she leaned in once again.

"Oh my, what a couple of naughty foals I have here...!" Izzy gasped, but otherwise made no move to remove them from their positions.

Now in a more comfortable position, Sunny continued exploring Izzy's folds with her tongue, getting adorable whines and squeaks from her friend for her trouble.

"Uh, Thunny? Her horn ith tharting to get brighter... Whoa!" Sprout said from on top of her. Sunny felt her unicorn friend go rigid for a moment, before feeling her squirt onto her tongue. She took the opportunity to get her lips around as much of her marehood as she could before suckling gently, until she felt her start to go limp, at which point she pulled away, licking her lips confidently.

"That... That wath tingly..." Sprout said, sliding off of Izzy and turning back to Sunny, who saw that his tongue was half-hanging out of his mouth.

"Well, you... You should have asked me about giving hornjobs if you were so curious about it, you little stinker," Izzy replied as she caught her breath, getting up on her hooves. "Don't worry, that will go away in a few minutes, or so I'm told." Izzy reassured him.

"It-it was actually my idea, Izzy..." Sunny admitted sheepishly, wiping her mouth with her foreleg.

"Well, I suppose it's only fair that you got one on me after I've seen both of you sparkle," Izzy commented, ushering them back into the playpen. Her ears perked at the ring of the doorbell from downstairs. "Well, now that you two have had your fun, stay here and behave while I go see who that is."

With that, Izzy turned and headed out of the bedroom again and trotted down the stairs to the ground floor, over to the front door, grabbing the doorbell with her slightly tingling horn, and opened it to reveal two very familiar pegasi.

"Hey there, Izzy," Zipp greeted, standing next to her younger sister Pipp. "I guess you're here too. We swung by to say hi to Hitch, and asked where we could find you two, and he said probably here. You girls busy?"

Welp, soon the whole gang is going to know. Stay tuned for more! Still not sure where I'm going with this, but that's probably half the fun.
