"Mr. Stark, we really shouldn't be doing this." The man behind him huffed out a quiet laugh.
Peter grumbled as Tony ground his front against the teen's ass, effectively pinning him to the rough pool wall. To the Avengers outside of the pool, it would look as if Tony was keeping himself afloat while hugging Peter from behind. This is pretty normal, considering how affectionate they act around the team. What the other heroes don't know is that the relationship they thought to be father and son is actually sugar daddy and sugar baby. Or at least something to that extent.
Although Peter sided against public indecency, his action of pushing his butt out toward the other male showed how he really felt about the situation at hand. It was hard for him to tell his daddy no, especially because all Tony ever does is spoil the shit out of him.
Tony squeezed Peter where he had his arms wrapped around the boy's toned stomach as he rocked his hips forward again. "Why? Scared of putting on a little show? I'm sure Bruce won't mind. That man is into some kinky stuff." He leaned to the side so he could nibble on the red ear in front of him. "I would know."
Peter gasped at the feeling of teeth and tongue on his ear, his favorite spot to be touched. It took him a second to process Tony's words. "W-wait. You and Dr. Banner...did stuff with each other?" He couldn't help but rub his knees together, giving himself some friction between his thighs. "That's kinda hot."
Loud and boisterous laughter erupted from Tony as he threw his head back, and Steve looked away from his conversation with Natasha to spare him an amused glance. Once the guffawing finally stopped, Tony looked back down to see Peter with his head down on his crossed arms alongside the pool. His neck was glowing a vibrant red, showcasing his embarrassment for all to see.
"Sorry, sorry. I didn't mean to laugh at you, baby." He slid his hands down to the boy's thighs and massaged them provocatively. "Want to hear about some of the things we got up to?" He rubbed his index fingers along the area where thigh and crotch met, still smiling.
Peter's head popped up immediately, once again gaining the super soldier's attention. He definitely wouldn't say no to that. What horny, nerdy, gay sixteen-year-old with daddy issues would? He nodded his head vigorously, showing just how badly he wanted to know what happened.
Tony 'tsked' at him in response, stopping the movement of his hands. "It's been a year already, and you still don't know the most important rule. Always give me verbal feedback. Now, what do you say?"
The brunette squirmed as he accidentally made eye contact with Steve before quickly looking away. "Please...tell me about...you and Bruce." Tony pretended he couldn't hear him. "What was that, darling? I need you to speak up, so I can understand you properly."
Peter could feel himself getting harder from the humiliation alone. It was clear that his daddy wasn't playing games and didn't care if Steve overheard what they were talking about. He swallowed around the knot in his throat and spoke clearly this time. "Please tell me about you and Bruce having sex, sir."
Tony palmed his own dick with his left hand and touched Peter's with his right. The boy let out a tiny mewl and planted his feet wider in preparation to be taken apart by the man's words.
"Mmmm, let's see. Brucie-bear was looking a little green from stress, so I asked him straight up if he wanted his dick sucked." The teen giggled at that. "When he finally gave in, I sat him down right in the common room where anyone could walk in on us. God," Tony groaned as he put both of his hands on Peter's hips and pushed their lower bodies together. "You wouldn't believe the sounds he made when I got my tongue on him."
As the billionaire continued, he pulled down the boy's swim trunks and boxers until they settled below his ass, making it appear fuller. "I almost couldn't take him all; he was so big. Every time I deepthroated him, he would snap his hips up and choke me on his cock."
Peter let out a low moan, and Steve struggled to focus on what Natasha and Clint were saying. Tony would have laughed if he weren't so hard right now. He proceeded to grip the boy's dick in his hand and stroke him slow but rough. Peter couldn't stop all the pants and whines that escaped his throat.
"But then, Bruce got this look on his face like he wanted to say something. So I gave him one more lick before telling him to spit it out already." Tony kept his shorts on properly and proceeded to thrust against the bare ass before him, mimicking the motions of sex. "You want to know what he said next, baby?"
Tony peered up at Steve, meeting his gaze as Peter stumbled over a breathy, "Yes." The man's hand moved faster over the teen's hard dick.
"He told me to bite his cock."
The next thing he knew, he felt Peter stiffen as he came into Tony's hand as well as the pool. Poor thing was shaking through his aftershock, so Tony rubbed his thighs once more. He bit down his laughter this time, knowing that Peter would be embarrassed for coming so fast.
"That's it. You were so good for me, honey." Tony reassured the teen. Peter leaned back and rested his head on his sugar daddy's shoulder, refusing to meet his eyes. "'M sorry. You didn't get to finish."
Tony peppered his face with kisses. "Don't even worry about it. There's plenty of time for that later." Peter grinned as Tony pecked his nose one last time. He turned to face the man curiously. "Can you tell me what happened next, please?"
"Next," Tony smirked as Rogers excused himself to the restroom. "Captain fucking America ran in and asked if anyone was hurt because he heard someone moaning in pain."
