I came across this awesome project on reddit and was wondering if the guy who made it is on here, or if anyone has something similar. It is a cage that he is locked inside that rolls under the bed to be stored while he is being cucked. As an added bonus he has fitted it with inflatable padding so that his wife (or her lover) can inflate it, squeezing him tight inside.
