The Art Gallery Bathroom

I’m at a small private art gallery with my girlfriend. I trick her into coming into the bathroom with me by telling her to come and look at the beautiful pink tiled walls. I lock the door and embrace her from behind, softly restraining her, and sticking my hand down her pants. I finger fuck her while we look out of the small bathroom window over a blueberry clustered hillside and the calm baltic sea. As we wait for the bus, she is quivering and I try to act normal so that no one will suspect.
