Her hips rocked back up towards his, and she started to rock up onto her knees so that she was sliding up and down on his dick, having him fill her up all the way each time she sank back down on top of him. Already she was a little breathless, grinding up against him as she felt his mouth on her skin. It made her nails dig into his skin, her hands palming and touching every part of him that she could. Her back bowed and she let him suck on her nipples, making her wriggle against him, "Fuck you are so gonna pay for that spanking Tony Stark.." she panted, moving a bit faster.
