The taste on Tony's lips was strange, but not all that unwelcome and he lapped at the other man's lips before Tony was moving away. Letting out a little breath, he moved to settle between Pepper's legs and spread her folds just like the other man had done. However he wasn't quite as confident with his tongue and instead leaned in to only gingerly draw his tongue over her, tasting, testing.
Finally his tongue found the little bump that was her clit and he lapped at it warmly.
