Friendly Neighborhood Birthday Man

Urgency

Peter decides to test the waters, so to speak, introducing Tony to a new aspect of their special intimacy.

Tony sat across Peter's lap as he thirstily suckled down two bottles of warm almond milk. The watery treat was extra satisfying after the sugary donuts, and Tony made the cutest whimpers as he worked to drain the liquid through the silicone nipple.

Peter carried the pajama-clad Tony Stark into the billionaire's personal bathroom, but he didn't start the water running right away. He was in no rush to change his older adult lover out of his cute and sexy baby outfit.

"You know, maybe we don't need a bath just yet. You're hardly dirty. Are you even wet?" Peter placed his palm over Tony's crotch feeling his dry diaper.

Tony thought for a minute before responding in perfect baby talk.

"Well, I hafta go now. I could go now."

"Oh, I see. You have to go now. You could go now. Or...you could wait. Right? I bet if you wait to go, it will feel much better when you finally do go, don't you?"

"You're going to make me wait?" Tony Stark was the quintessential brat. And he knew it with his puppy dog eyes and full-lipped pout.

"Yeah, Baby. I think I am. But not just wait, I'm going to do something in the meantime. Now, how would it feel to let me touch you, and then you explode? I bet the relief would feel really good, huh, Baby?"

"Yeah...That would probably feel really good." Tony agreed and seemed to relax against Peter's chest as Peter reached into his lover's diaper, palming his erection and eliciting a whimper.

"Just a second...." Peter paused his motions briefly as he reached over and...started running the bathwater. The sound was intensifying Tony's need to relieve his bladder.

"Hey!"

"Sshh...! Relax, Baby." Peter cooed as he stroked Tony's member inside the warmth of the padding, using the leaking precum as a lubricant.

"Oh, now I really have to go," But Peter ignored him, "Daddy! Please, I have to go!"

"You'll get to go in just a minute, Sweetheart." Peter increased the speed of his strokes, pleasuring Tony. He repositioned himself behind his diaper-clad lover with one hand on his cock as he brought his other hand to Tony's lower abdomen placing the slightest pressure on his bladder.

Tony moaned with need.

He closed his eyes and relaxed, leaning his head back against Peter's chest in submission.

"That's it," Peter kissed Tony's hair, "let Daddy take of you. Just relax."

"But, Daddy...!" Tony whined in the most precious baby voice. Although it was hard not to obey Peter's raspy Queen's accent as he said to 'relax.'

Peter devilishly placed slightly more pressure on Tony's bladder, which felt full and distended with the two bottles he had earlier.

"Just think how good it's going to feel..." Peter worked Tony's member harder and faster, paying special attention to the sensitive spots.

His cock felt amazing, but the sound of the water rushing into the bathtub made it hard for the older man to concentrate. He felt hot, and he tugged at his onesie.

Peter removed the fleece, but the time taken only prolonged relief for Tony, who was now only wearing the white padding with the teddy bear pattern. He looked so near perfect, Peter thought. The only thing that would make him look more perfect would be wet padding, bulging, and sagging, with Tony moaning in relief.

Peter was turned on now as his own erection prodded Tony. He continued to work Tony's throbbing, leaking erection as the man whined and moaned.

Tony couldn't take it anymore. He came with a moan, and Peter felt his hot come fill his hand before filling the diaper. Tony panted until his breathing slowed for what came next.

But Peter didn't remove his hand. He kept one hand on Tony's bladder, urging his release.

The older man threw his head back into Peter's chest in relief as the first trickle of urine escaped and snaked through Peter's fingers.

"But, Daddy! I'm..."

"I know, Sweetheart. It's okay."

With Peter's permission, Tony's stream increased pressure into a steady flow then into a full-on gush. The liquid came too much too fast to be absorbed right away and first flowed around Tony's ass and groin.

After he had finished expelling all of the urine and the diaper finally absorbed the liquid to full capacity threatening to leak with the slightest misstep.

Peter removed his now wet hand and cupped the diaper, feeling its dense fullness.

"How was that, Tony? Was that okay? Was it too much?"

"I actually really, really liked that..." Tony placed his hand over Peter's, also feeling the fullness of the padding.

"Me too. I think we are ready for that bath now." Peter spun Tony around into a wet and longing kiss.
