That's definitely a way to say 'thank you', even if Wanda's not entirely sure what he can feel. She wants to pry. Can he feel the heel of his palm? His fingertips? Knuckles? How does it feel?

Her breath hitches before she twists as best she can to face him. It's a little awkward; she should've straddled his lap and turned to face him, but she knows she hadn't been brave enough, preferring to hide with her back to his front.

She pulls her right hand away from his metal arm and reaches awkwardly to touch his face. "I don't mind," she murmurs, leaning back toward his left shoulder and turning her face toward him.

She plants her left hand on the top of his metal one and frowns. "Is it okay?" Even when there's pleasure to be had, Wanda's still all business.
