Tony's face seemed to light up when Steve agreed to let them experiment around to see if he liked it or not. He stretched out next to Steve and ran his hand over his nipples and down his taut stomach, letting his fingers dance over his skin to his inner thigh and massaged him, palm cupping his balls and massaging them as Pepper teased the head of his cock. "I can keep you distracted as she works you open," he murmured as he curled more towards him, his cock slowly stirring to life against Steve's hip. Arching his hips, he gently rubbed himself against his skin, his fingers tweak one nipple as he sucked on the other, doing his best to get Steve's mind off the fact Pepper was about to touch his ass.
