Something that really turns me on in general is the idea of having my ass used in some way to discipline or punish me for bad behavior. One of the ways that I have fantasized about for a while now is being forced to accept an ass fucking from an ice dildo or forced to hold the ice in my hole for a period of time. I have tried it on myself and it can get quite painful. It would be very very good discipline for me I know.
Has anyone used an ice dildo for this type of discipline before?
What other ways have people used ice dildos?
