Mistress Kiana loves to fuck her slave in the sling. The sling is such a useful piece of dungeon equipment as the slave can be easily position so you are comfortable when fucking them in the ass with your strapon. As this slave is going to find out, it isn't as comfortable to be on the receiving end especially when your balls are getting some cbt and your nipples getting some electro play.

Mistress Kiana eagerly fucks the slave in the ass, only pausing to work on his balls and nipples. What a lucky slave to get fucked deep and hard and have some foreplay in the process.
