"Suck me, Tony. I want that clever tongue around my cock."
"Pep, it's not a cock, it's a—"
"Suck it, or I go in dry."
Tony blinked, unnerved, but didn't say the safe word. Instead, he took the strap-on into his mouth, and downed it all the way in until he could swallow around it, and use his lips to caress Pepper's clit. It wasn't hard—they never used too large a strap-on. It was a bit uncomfortable, still foreign and cold, and yet Tony Stark found himself fisting his cock until it ached.
He listened to those receptive moans when his lips reached down to that cute little nub, and so he reached it over and over again.
"Alright now, Tony. Over the couch."
"Yes ma'am!" Tony barked, as boyish and witty in those two words as he usually was in a full sentence.
He bent over, she slipped it in, and they made something like love.
