"I know slave, and as i mentioned before, we're gonna try to maximise your potential orgasm to the fullest this time. I mean, you wanna be a very good boy for me, don't you slave?"
"Y..y..yes mistress, i swear, please"
"Good, you know, all boys who do good jobs are getting rewarded sometimes. You do know that, right?"
"P..p..please mistress, please, i swear"
"Hope is such a powerful emotion, isn't it slave?."
"..."
"Hmm, why don't you go ahead and say it out loud slave. Say "I wanna be a good cock stroker for you mistress Stella". Make me believe it..."
(You repeat the sentence)
"I hope so, but.., go on.."
(You keep repeating it over and over)
"Alright, that's enough slave. Go ahead, you can stroke as much as you want right now. Treat your cock well for me and give it what it wants. Touching and rubbing and stroking. Really take your time and don't rush anything"
"T..t..thank you mistress"
"Stroke it with purpose for me slave"
