The fantasy of being used by strangers, in any way they see fit, of being unable to resist or have any say, is very common. It's an amazing fantasy and it works into a lot of the writing and scenes that me and my boy have. But I often run into people who can't understand the difference between negotiating for play and telling people about their fantasies.
The reality of that sort of play is terrifying. The fantasy might be amazing and mind-blowing, but trusting your body and your self to a stranger, or even to someone you know, without the option of safewording or escaping safely... terrifying.
On the plus side, it makes for some sexy art.
Go thank Coffee Cream for the art.
