If Mandy was confused, then Nathan was probably even more so. He wasn't an exceptionally generous lover, though he always managed to look after Mandy well enough. Until tonight, that was, and now he just didn't know what was going on.
He just lay there for a moment when she rose and walked to the bathroom, brow scrunched. For the first time in practicaly forever, he felt a bit... inadequate, and he was not pleased with that feeling.
His concern for her outweighed his frustration with whatever was going on, and after a minute or so he rose and followed her on quiet feet to the bathroom, seeing that she'd already turned on the water and stepped inside. He stepped in too and embraced her from behind, nuzzling her neck in another silent apology.
