Erin repositioned herself as soon as Nathan rolled and moved her on top of him.  Much better this  way than being pinned under him.  He was a lot bigger than her.   Bigger than the last man she'd traveled with, too.  She slid down to straddle his his hips, a good way to gage his interest.  Resting one hand on his shoulder and the other on the bed, she leaned over him, letting her breasts just  graze his chest.  She lowered her head, at first to kiss him, but then moving to explore his neck with her mouth instead, pushing his long hair out of the way and running a hand through it as she did.
