Sandbar was only a little wet by the time they had arrived just outside Sugar Cube Corner, but Ocellus took his diaper off of him regardless and helped him clean up before they headed out into public again. Silverstream had obviously done the same with Smolder, as she was sans dress, diaper, and smelling just fine when the five of them headed in to sit down around one of the round tables and ordered milkshakes all around.

It immediately became apparent that Silverstream and Smolder were now dating. The way they looked at each other, talked to each other...

Plus the fact that they said outright that they were dating.

The stallion had to admit, it would be nice having another playmate in his bedroom with him, as well as no doubt beginning to see a softer, more submissive side of his dragon friend as she slowly molded and pieced together that new side of herself.

"Can I just really speak my mind right now?" Sandbar told the rest of the table. "I'm incredibly happy for the two of you, I just hope Yona doesn't feel too left out, ya know?"

"Don't worry, Sandbar," Dawn-Ocellus told him. "She's incredibly happy for you and me, and I know she'll be the same for Silverstream and Smolder. Trust me, the love I sneak from her sometimes is full of happiness for her friends. When she's ready to try again for a significant other, I believe she'll be stubborn enough to not let anything stop her."

So with their shakes quickly approaching noisy-straw-slurping levels, Ocellus raised her glass for a toast.

"To Silverstream and Smolder, yet another happy couple from our circle of friends!"

"Hear, hear!" Sandbar agreed, offering up his glass, joined quickly by Terramar, Silverstream, and Smolder. "And the two of you are absolutely welcome in my room anytime you need to get away for some playtime."

"Thanks, Sandbar. We'll definitely keep that in mind. But I'm sure you have enough trouble explaining Ocellus' green mist to your parents, I don't want to add smoke to that list, and make them concerned that something might actually be on fire... Other than my loins..." Smolder said, blushing with a giggle.

"So we'll turn a fan on and open a window," Sandbar immediately countered. "It's not like you're the only one. Ocellus has glowy mist, you have pink flames and smoke, Silverstream has... Noise..."

'No kidding,' Ocellus thought, as she watched the hippogriff blush. They could take a few educated guesses as to what those two were up to on the ride back into town, but there didn't have to be any guessing when Silverstream hit her peak, as they all heard the eagle scream coming from the carriage, thankfully before they had hit city limits.

"Y-Yeah, that is something I have to work on... It took me by surprise, and there was nothing to scream into..." Silverstream admitted, getting laughs from the rest of the table, and an embarrassed look from her little brother.

After making sure the front door was locked and the rest of the lights were off, Sandbar and Ocellus retired to his half-bedroom half-nursery.

"Well, who wants to get ready for bed first? You or me?" Ocellus asked him, still holding her Dawn form as they walked together over to the changing table.

"What do you need to do to get ready?" Sandbar asked her.

"Well, I have to admit, little bro, you enjoy it so much that I get curious sometimes, so..." Dawn-Ocellus trailed off, stepping up onto the changing table and rolled over onto her back. "I think I'll wear with you tonight."

Sandbar repressed a shudder of anticipation as her feedmate spread her legs, revealing this form's moist marehood.

"Come on, get me padded up, but..." She paused, glancing at his erection as he grabbed supplies. "Feel free to have some fun with your big sister first. Certainly not going to be able to get your diaper around you with that poking out."

Sandbar blushed as he grabbed a fresh diaper and began to unfold it. Ocellus was just teasing; he knew for a fact that his diapers could fully contain his erection; they rode high enough and were thick enough to only give away slight hints of his arousal, and would stay on if the tapes were tight enough, and if they weren't, hey, there was always duct tape.

Sandbar got the thick diaper unfolded, and Dawn lifted her back end up long enough for him to slide it underneath and get the top set of tapes fastened around her tail, before she laid down on it.

"Mm, nice and soft..." Ocellus said.

"Sounds like you want something nice and hard, though," Sandbar replied, stepping up onto the second step at the end of the changing table, beginning to loom over her, his erection twitching between her legs.

"Mmhmm, show me what you've got, little bro," she answered, her eyes glowing green momentarily as mist rose from her nostrils as her lips gave a sultry smile. Sandbar smiled back as he put his front hooves on both sides of her barrel, leaned forward, and slid inside, hearing the diaper crinkle underneath their combined weight.

"Ahh... I'm learning to love the biggest part about you..." Ocellus told him pleasurably, not leaning into it, but letting her feedmate do the work.

"Mmm... You're... Amazing..." Sandbar whispered to her as he softly thrust inside, keeping his pace slow, but made sure to bottom out with each thrust, reaching the deepest corners of her nethers. He wanted to stay slow because the evening had proven to be quite the buildup, and he wasn't going to last very long regardless. "So amazing... Thank you for letting me do this...!"

His pace only got a little faster as he put more weight into it. Ocellus' eyes glowed brighter as more mist emanated from her nose and mouth.

"Come on, little bro, give me your big stallion juice!" Ocellus told him, her breathing quickening as she spread her legs a bit farther.

That was all Sandbar needed. His pace faltered, and he shuddered as he got ready to hilt himself into her and hold himself there.

"Ah, big sis!!!"

The build-up that had started when Silverstream had first told Smolder to get on her claws and knees two hours ago finally came to his tip, and he gave his strongest thrust and began to coat her inside walls with his seed. She remained conscious enough to take in the look of absolute euphoria on his face through the green haze that was rising to the ceiling. As he breathed some of it in, it only seemed to prolong their climax as he felt her inner walls close in on his cock, milking it for everything it could.

After several moments of feeling the last of it dribble out, Sandbar slowly began to pull out.

"I hope you can finish padding me up..." Dawn-Ocellus said as they both caught their breath, as she felt the stallion's deposit begin to seep out of her and seep down her taint and dock.

Standing back on the steps at the end of the table, Sandbar caught his breath and grabbed the bottle of foal powder from the shelf below, twisting the cap open and sprinkled liberal amounts of it down on her marehood, before bringing up the front of the diaper between her legs, smoothed it against her stomach, and brought the back wings up and taping it snugly up.

Her mist beginning to clear, Dawn-Ocellus sat up and quickly hopped off the changing table, and helped Sandbar up to take her place, laying on his back as he continued working his way through the afterglow. By the time she grabbed a diaper and took her place on the steps between his legs, he had gone completely flaccid.

"You sure can show a sibling a good time..." Ocellus said, the glow in her eyes dimming as she unfolded the diaper and got it underneath him and around his tail. She gave him a quick dusting of foal powder before getting it taped snugly up, and pulled him up by his front hooves into a sitting position, before giving him a kiss on the snout.

"There we go, all set for the night. Lets get into bed," Ocellus told him. His legs still a tad wobbly, Ocellus helped him down off the changing table and walked together over to the crib. She shut the bedroom light off before climbing in with him, and leaving the bars down for the night, as it would make getting out a bit tricky with both of them in there. Sandbar snuggled up to her barrel, letting her wrap her front hooves around him as their diapers pressed into each other.

"This has been an amazing Spring Break. It's hard to imagine that we're not even halfway done..."
