She gave a sort of half sigh with him in her mouth, letting him thrust up into her mouth. Her swollen lips were tightly wrapped around him, slickening him up with spit as he slid in and out of her mouth. After sucking on the tip for a moment, she let go if only so that Steve could touch him if he wanted. She let her fingers slide down between Tony's legs, teasing the tip of her finger against his ass just a little. "He likes being teased.. and having his nipples licked and bitten.." she said amusedly, still licking and sucking on him here and there while she watched Steve out of the corner of her eye.
