"And who knows slave, maybe if you keep on behaving like you're doing right now i'm gonna let you shoot that big, monster load at the end of all this. What do you say slave, huh?. Can you imagine how that would feel like?. Yeah, you want that feeling, don't you slave?. You want to cum a lot for your mistress, don't you slave?"
"Oh, p..p..please mistress, i..i..i'll do a..a..any...."
"I know, you can already feel it, can't you slave?. But don't worry about it, i'll tell you when and where and how and why and if... Although, you can always beg for it of course, that never hurts in a situation like this, does it now slave?"
"I..i..i"
"Ok, now spread your legs a little wider and let me have a closer look, i wanna see. Spread them apart as far as you possibly can please.."

"Good, i want you to stay in this position slave..., clear?"
"Y..y..yes mistress Stella, please"
"Look at that, i almost forgot about that shoelace.., poor thing. Well, you can loosen up the knot a little if it's starting to hurt, but I wont allow you to take it off.."
"..."
"Alright, now do a few, little, quick strokes right down the middle of your shaft, but make sure your strokes are still really tight slave. Can you do that for me please?"
(You do what she demands)
"Tight and fast slaveboy, tight and fast"
