No objections here, ma'am. He lets himself fall against the bark, itching to get his hands on her but holding back to give her room to work without tangling their limbs togetherness yet. His heart is racing in the best way, and suffice it to say if she changes her mind again... Well, then he'd be very disappointed.

He shifts his hips beneath her hands without meaning to, eager and practically panting against her mouth. If she's decided, he's certainly not going to argue the point.
