Loki shook his head to suppress a laugh. He wasn't in the mood to laugh. Not at all. Not when he was dressed as a woman and not allowed to have the actual form of a woman. Not while he was mostly supervising Thor to make sure he actually got his hammer back.
“Thor,” he said still shaking his head, “Surt looks far more feminine than you do and he's probably the most manly giant in Muspell.” And Loki would know. He was a product of Muspell. “I suppose we could try to make this work somehow. You don't move like a woman at all.”
Sighing, Loki crossed his arms over his chest. “You're a married man, have you never watched Sif walk away. You might be lacking the curves of a well-built woman,” And Sif was probably one of those most well-built women Loki had ever seen or held in his entire life. “But try to walk like you're a little heavier down here.” Then, to tease, Loki slapped Thor on the bottom.
