I like the casualness of the tone between Heather and Aidan. There's no pretend shame since it's not their actual bodies they're inhabiting. I always imagined (often and in great detail) that if this ever occurred to me, I'd probably not feel a whole lot of embarrassment about it. It's not like I've spent a great deal of my life hiding boobs (that I don't have) or being embarrassed about a nip slip. If the owner of the boobs started fondling them, I'd probably go "meh, sure, they're yours, fondle away!"
