Gretch tugged gently on Natalie's ear with her teeth, debating on what to do. While they were currently sheltered from view, it didn't mean they'd stay that way for long and Gretchen wasn't much of an exhibitionist. Not that she felt the need to keep her sex life private and quiet, behind closed doors, she just didn't get off on the idea of someone watching her, aside from Trevor of course, who seemed to be the exception to every one of Gretchen's rules.
Sliding her hands between them, Gretch ran her fingers along the curve of Natalie's breast as she slipped her thigh between the other woman's, all the while listening carefully for the sound of anyone approaching.
