Any one have experience with either being tied up and force fed or on the other end? Looking for tips and advice
Not sure what you consider long-term? I have spent an entire weekend bound in bed as part of kinky play, with only breaks for the washroom, but nothing longer than that.
Years ago, when I was still thin (but still a lil' kinky) I wore a chastity belt for 3, maybe 4 days... That was an interesting experience, too.
What kind of tips or advice are you looking for?
