Friendly Neighborhood Birthday Man

The Bratty Baby

Peter's wish comes true.
Spider-Man's bratty baby gets the punishment of a lifetime. Things heat up and turn into passionate lovemaking and roleplay.

Tony had flown Peter to Milan for an extravagant second date. Peter had opened up about his secret desire to role-play with Tony Stark, but did his best to keep things light.

Peter was quick with the champagne for Tony, even bottle feeding him more. But now Tony voiced concern for what the alcohol would do to his bladder.

Peter wasn't ready to explain why, but the thought alone made him incredibly turned on.

"Remember when I said...that what I want might be too...weird?"

"It's new, Honey, but I'm really enjoying this. I like being your baby." Tony teased.

"Well..." Peter had his bag in his arms. "Some babies need special...protection through the night."

"You mean like...condoms?"

"Bladder protection." Peter squeezed the bag making the items crinkle.

"Bladder protection...? OOOH!!" Tony got it. "Okay! No, that's...totally okay! In fact, before my Iron Man suit had a filtration system, I dabbled with the idea. Not weird at all."

"You mean it? You really are the best!" Peter pulled Tony in for a passionate kiss.
He then positioned Tony on his back and pulled a large, white, adult-sized diaper out of his bag. It even looked like a baby diaper with little teddy bears and balloons across the front.
"You sure, Baby? You can change your mind or ask me to stop at any time! Just tell me you aren't having fun anymore, and I'll stop."

"Oh Baby is having A LOT of fun...Daddy!" Tony raised his hips, and Peter placed the diaper underneath. He threaded the front through Tony's perfect thighs and taped it tight.
Tony reached down to feel it and hear the crinkle. He liked the security the soft, tight garment gave him.

Turned on and buzzed, Peter pinned Tony to the bed wearing nothing but a hotel towel.
Tony on his back, reached down and tugged at Peter's towel.

"Hey! That was very naughty!" Peter whispered in Tony's ear.

Tony unapologetically bucked his hips into Peter. Then his hands grasped Peter's towel harder and slowly started to slide it.

"You'd better behave, Baby!" Peter said with mocked warning.

"Nuh-uh!" Tony baby talked.

He then pulled the towel away from Peter and threw it on the floor.

"That was very naughty, Baby-Tony! You had better behave or else...!"

"Or else what?!" Tony teased in a babyish tone.

Peter was loving this!
Tony was loving this!

"If you don't behave and do what Daddy says, you will be punished!" Peter falsely lectured.

"No!" Tony said defiantly, making the perfect bratty baby.

"I mean it, Baby! I'm warning you!"

"No! No, no, no!" Tony kicked and wailed underneath Peter. Peter kept his bratty baby pinned down.

"Okay, but don't say I didn't warn you!"

In one fluid motion, Peter flipped Tony so that he was bottoms up across his lap. His cheeks peeked out of the bottom of his diaper perfectly!

Peter took a minute to admire his love like this. Tony's body was built and sculpted, but his ass was soft. Peter stroked and caressed the iron man before...

WHACK!

Peter slapped Tony's ass. The impact made it jiggle just slightly.

"Hey!" Tony protested.

"This is what happens to bad boys. They get spanked!"

*WHACK!*

Peter spanked Tony again and again.

"Oh! That stings!"

"This is going to hurt me a lot more than it hurts you!" Peter played the Daddy role very well.

"Oh, Daddy! Please!"

"Not until you've learned your lesson. This is the only way you'll learn!"

*WHACK*

Tony's moans were starting to sound more pleasure than pain. He loved giving himself to Peter like this.

*WHACK*

"Are you ready to apologize and be a good boy, Baby?"

"NO!" Tony balled up his fists and flailed in Peter's lap.
He was practically begging for it!

"You're going to learn your lesson, Tony!"

Tony was facing away while face down on Pete's lap, but he could hear the flip of a bottle cap. Suddenly a cool wetness teased his buttocks.

"Ready to apologize?" Peter entered his hand into the leg of the diaper and gently ran his lubed finger up and down Tony's ass. Pete could feel Tony's breathing change to deep and rapid. He felt his erection too.

"N-no...!" Tony managed, weakly. This was acting. His words protested, but his body relaxed. Anticipating what came next.

Peter gently teased Tony's rim. The nerve endings went crazy. Tony moaned but kept his fists balled up in defiance. Peter prodded at the rim and slowly, gently entered just to his first knuckle. Tony was relaxed enough. And slick enough.

Peter gaged his boyfriend's reaction as he slowly slid his finger deeper. Until he reached a special bundle of nerves.

"Oh....oh Peter..." Tony whispered breathily.
Peter gently massaged Tony's prostate.

"Oh, Peter!" This time Pete removed his finger and delivered a smack on Tony's ass. "Daddy! I mean daddy!"

Peter gently slid his finger back in a little quicker, this time to Tony's pleasure.

"Oh, Daddy! Oh...Daddy!" Peter quickened the pace, practically vibrating his finger on the sweet spot. Then he slowed down, mercilessly teasing the bratty Tony.

"Oh...I'm so sorry, Daddy! I'll be good! I'll be good, I promise! Please don't stop!"

"That's what Daddy likes to hear!" With his other hand, Peter delivered another smack to Tony's ass while he kept his finger inside of him.

"OHMYGOD!!" Tony was in ecstasy. He pushed back into his daddy's fingers rhythmically, loving the little bit of friction against his penis provided by the diaper. "I'm going to...oh I can't hold back I'm going to...I'm going to come!!"

"Oh...I don't know, baby. You've been very naughty! Only good boys get to come today!"

"I'll be good!" Tony begged. Peter quickened the pace on the nerves. "I'll be good! I'll be good! I promise! Please don't stop!"

"OhYESyesyesYES!" Tony mumbled as his whole body constricted in Peter's lap.

Pete quickly flipped his love onto his back, pinning him down so that he could see his face as he came. Tony spilled his seed into the diaper. His breathing slowed, and he relaxed.

His member was still releasing liquid.

It was urine. The whole diaper swelled and grew hot and warm. The relieved look on Tony's face was too much. Peter kissed him, entering his tongue into his lover's mouth.

"Uh oh." Tony broke the kiss. "Daddy, I'm wet." Tony feigned embarrassment.
It was a beautiful sight.

"Don't worry, Sweetheart. Daddy will change you."
