Total Obedience
"Not that i really want it, but. Keep going, make sure you're working that head as well as your shaft strokerboy"
"Y..y..yes mistress Stella"
"Is your dick nice and wet slave?. Let me hear it, i wanna hear that wet, fapping sound while you stroke yourself"
(You spit on your cock once again and stroke yourself harder)
"There you go, make it feel as if you're sliding into a wet pussy slaveboy. Keep your hips still and just pump that cock for me. I don't want any mistakes"
"F..f..f"
"Feels so fucking good to stroke yourself when your mistress permits it, doesn't it slave?. I know, if only there'd be some kind of a happy ending for you. If only i would show some pity for you and all your wanking.."
(You try to plead with her)
"Well, how about a thank you instead for letting you have so much pleasure?"
"T..t..thank you mistress, p..p..please"
