We have a tiny dicked gym admirer that constantly watches me, and my feet in particular. We've caught him taking pictures, and eventually invite him to workout with us and then come back to our house. We propose that he be our beta foot cuck, and that he gets to participate as often as we want as long as he submits to worshiping my feet, keeping them lubed while I give my husband a footjob, and cleans up the cum after every single time. Obviously, he accepts willingly, and does everything we ask.
