Tiles and Grout

Girl and guy making out in the bathroom. They left the door open.

Girl: "Stop okay. Look. I don't think I can do this again."
Guy: "Why?"
Girl: "My mom says she dated your dad in university."
Guy: "Really. What's wrong with that?"
Girl: "Just thinking perhaps last night was perhaps incestous or something."
