"You are a dirty little slut aren't you."  He pulled out of her and walked up the the fetish shelf.  He pulled down a set of nipple clamps and a collar that said slut on it.  He ripped open the package and pulled out the clamps.  There was a chain that connected the two.  He smiled and looked forward to using it.  He put each clamp on her nipples and gave a gentle tug on the chain.  He then fastened the collar around her neck.  "This is just a reminder of what you are."  And he slid his cock back in her ass.
