One of my friend's 18 year old son (still living at home) recently got caught by his older sister all greased up in the nether regions, butt naked, and mid stroke with a towel ready, and a pornsite up on their computer in there downstairs office. The parents had left home to go to a concert and hotel for the evening, and the older sister just decided to stop by...
We all got a big laugh out of that one...
