I came home from class wanting to take a nice hot shower but it was broken so I went to take one in my mom's bathroom. While having fun with myself in the bathtub, my mom's boyfriend, Bill, came home. He heard the water running and naturally he thought it would be my mom. Acting on his naughty thoughts, he took his clothes off and entered the bathroom with a raging boner. So it was a big surprise when he found me there.
