"I think now you start to understand how this goes slaveboy.."
"Ok, now do it the other way around.."
"Start with a very slow pace and stroke only the first half of your cock, getting faster and faster by the second until you feel your cum crawling right up into your cockhead"
"I want you to go so close to the edge that it's almost dangerous slaveboy.."
"Yeah, right there when you feel like your dick is gonna explode and then stop and hands behind your back immediately!"
(You gather all your strengh and stroke yourself to the edge as instructed)
"F..f..fuck please, s..s..s"
"Your balls must feel like a bruise right now.."
"Well, i hope it doesn't hurt too much yet edgeboy?"
"Because we aren't nearly finished yet working on your aching, swollen blue balls"
"I want them more swollen than they've ever been.."
"Please mistress i did every..."
"Quiet slave, i don't wanna hear any complaining from you!"
"That's a total no go in here.."
"You can beg me if i allow it, alright?"
(You lower your head)
"Slaves like you are so weak and pathetic.."
"You literally have no control when your dick is hard and your balls are full.."
"Well, take a short rest, you'll need it, believe me"
