Anyone know how to find this story?

I've been looking for a story that I saw a few years back. It was about a boy and his mom's friend. He had come back from school or something...his mom and friend were in the house. He went upstairs to shower, and his mom's friend came in and joined him.

I've tried to find it using the search function, but no luck. Does this sound familiar to anyone?
