Mmmmm maybe a chain on your futon would make our casual cuddle time much more interesting, having to ask to be freed to use the bathroom? Hot! Being told no? Even hotter @sircopper
Similarly, having your Owner wear a wrist cuff with your leash locked to it can be a nice way to keep a girl at your immediate beck and call, wherever he decides to plant the two of you.
Or offered a bucket, eventually, and chain remains in place.
