If it ever happens to me I hope the lady calls 911, eliminates any embarrassing items and waits for the assistance to arrive. If asked she should tell the truth, that I am so irresistible that young ladies all over can't wait to have sex with me :-)
I would say for her to leave but I would probably be at her place and even if that is not the case it could cause bigger headaches for her. She should also know that I died happy if that is what happens.
