Breaking the kiss softly, Tony sat up to watch Pepper tonguing Steve's hole like that, his hand going down to his own cock to jerk himself as he watched her opening him up nicely. He couldn't wait to bury his cock inside of him, knowing he was going to be very tight. As he stroked himself, he reached over with his free hand and stroked Steve some more, his mouth open and licking his lips as he saw her finger pumping inside of him then adding another. He'd managed to get himself nice and hard again what with watching his best friend take those fingers and squirming around. Laying flat on his back again, he curled a little toward Steve, Tony's hand still on his own cock as he lubed up his hand with the precum and stroked faster.
