"That's nice to hear, good, so you have to learn how to be a cock first. You know, learning what it means to be a hard, throbbing cock for your mistress, if that makes sense to you.."
"I..i..i don..."
"Tell me something slave, why should your mistress keep you around if not for your cock?. That's all you really are for your mistress, just a hard cock. So therefore you have to learn how to be that first slave. Learning how much you can take before you start to dribble pre cum for example. Or learning how quickly your balls start to swell, how tight and achey they can get, know what I mean?"
".."
"Well, you also have to learn how much you have to build it up for your mistress and how much you have to endure for your mistress... But more than anything i want you to learn how helpless your cock gets once it reaches a certain point and how to control yourself."
"..."
"You see, i know what i want in a cock, and a slave cock like yours has to be durable slave. It should never get tired and it never should cum without permission because it has to fulfill all it's mistress her wishes at any given point in time slave.."
"P..p..please mistress"
"What?..., oh, and let's be fucking real here, you only did some very basic edging and stroking here with me as far as i'm concerned slave..."
"P..p..please mistress"
"Easy over there slave, try to learn something while you rub your dick.."
