"I will," Calvin grinned. He took the things he learnt about the people he played with seriously, and even more so when the person he was playing with was his nephew. He chuckled at Tristan's words, and pointedly reached out to grip Tristan's hard, leaking cock, and then licked his fingers clean of his nephew's precum.
Calvin laughed a little, before groaning as he felt Tristan's big dick at his hole. "Good boy," he winked back, before gasping out as Tristan pushed into him, gripping at the sheets underneath them. "Fuck yeah I do, you're being so fucking good for me, you know that? So fucking good, so proud of you."
Tristan watched as his uncle - his massive, gorgeous, sexy fucking uncle - reached out and gripped his cock, calling attention to how turned on he was. Even if he wanted to conceal his arousal at this point, it'd be futile. All bets were off, and somehow, in this room, just the two of them, Tristan felt perfectly safe to let loose and make his attraction to Calvin obvious - even if that placed him in a more submissive position underneath the Dominance his uncle so effortlessly radiated. His eyes wavered, watching Calvin slurp the pre-cum from his own cock off his digits; the view actually made Tristan audible moan. "Fuck..." He breathed.
Tristan gulped when Calvin called him a good boy. He wasn't supposed to like that. He even fixed his face so that it might appear as though he didn't; looking gruff and mildly irritated - but his cock twitched, throbbed even in response, so his cover was pretty much blown. He tried to make up for the vulnerability by thrusting roughly into his uncle's tight hole, "God..." Tristan moaned, throwing his chest out and his head back as Calvin's tight hole clenched around his length. "You're...proud of....mmf..." Tristan ducked his head, focusing on Calvin's thick, leaking cock laying back against his sculpted abs so that they wouldn't have to make eye contact when he said, "...Thank you, Sir. I...I want you to be proud of me." He said softly, shook his head, then canted his hips back to thrust them forward into Calvin's ass, filling him all the way up. At that point, he set the pace, fucking Calvin roughly, falling forward so that he was semi-laying on him as he plowed into his hole, jerking off Calvin's cock with both their abs as it was sandwiched between their bodies. Tristan was braced up on one hand while the other ran through Calvin's thick hair as he rushed in for a deep, messy kiss.
Calvin had been paying attention when he'd called Tristan a good boy. He'd known there was a chance that might blow up in his face, since his nephew professed to be a dominant leaning Switch, but he was pleased to hear that Tristan was enjoying the attention.
"You're doing a lot to make me proud of you, Tristan," Calvin said back, just as softly. He groaned out as Tristan plowed into his hole, and jerked his cock for him. "You're doing so fucking good, you're a good boy," Calvin groaned out, before Tristan started a deep, dirty and messy kiss.
