The giggle caused Peter's lips to curl into a smile, loving just how comfortable they were with one another, as he leaned his lips away and looked down at her with said grin, "Are you laughing at me, Agent Carter?"
He then leaned forward to catch her lips again, a deep groan escaping as he kissed her, when he felt her back arching up against him, moving comfortably inside of her, loving the way her walls felt around him.
