Amy chuckled, and nipped at her neck again playfully.  "Such a dirty, naughty girl, but such a good girl too.  And remember, good girls clean the one that fucked them to show their thanks."  She patted the girl's head and stood back, and waited.  God the little slut was a good fuck.  And she was gonna stay that way too.  Amy would never loosen her claws from the girl.
