That was more like it. Tony had been starting to dwell on the same incident since Pietro's lukewarm response-- after all, last time he had been in this house, Tony had been greeted with an exuberant hug. It wasn't really like Pietro to not come out and say it if he was taking offense to Tony's actions, but maybe sleeping with his sister was a kind of singular disturbance. For Tony's part, he blamed Nick for the entire incident, and he'd have his revenge there. He'd much rather just make up with Pietro.
His knuckles skimmed down Pietro's stomach, just under his bellybutton over silvery hair like that Tony still fingered along Pietro's jaw, and he watched two fingers hook over the waistband of Pietro's pants before nudging Pietro's chin to turn him into a light kiss. "Maybe we should wait for your sister, hm?" he suggested, chuckling against Pietro's lips and sharing another teasing kiss.
