My Roommate Insists on Scrubbing My Feet

[Help] My roommate insists on scrubbing my feet for me. What should I do?! Urgent!! Waiting for replies!!! Here's what happened: Every time my roommate asked me to shower with him, he'd scrub my back. I refused at first, but he was so good at it that it felt amazing. I figured we're both guys, so I let him do it. Of course, I didn't let him do it for free. Sometimes I'd scrub his back too. But I never expected my roommate to recently get into scrubbing my feet! Yes, you read that right. Scrubbing my feet!! Scrubbing my feet!!! How can I politely refuse and tell him that a man's feet should only be scrubbed by his future wife?! Urgent!! Waiting for replies!!! No. 0, OP Handsome Enough to Split the Sky A short forum-style story. This time, the OP finally gets to be the top, lol. Theme:
