In desperation trying to find post of this story-weight bench-sister's friend!

There was a story posted in the early 2000's (probably 2001 or 2002) about a boy who brought his sister's friend down to the basement where he had a weight bench. He tricked her into letting him tie her up face down on the weight bench. He noticed her cute dirty soles and proceeded to tickle torture her feet! Great story! I can't find the post of it as it is a little older. Does anyone still have that story? I would really appreciate it if someone could post it again. Thank you TMF community.
