...just a little tighter, I wanna see your veins throbbing, ... that's it.
Give it a couple of strokes, then just lightly slap it from side to side.
I want to talk to you. Keep slapping.
I understand Mistress Charmane had a word with you earlier. You know, you don't have to listen to her, she's only acting in her own interest. Sure, you'll fail the test if you cum, but so what right? You don't even know what this test is all about, or how you got here. You'll find out eventually, but why bother passing a test you never wanted to pass in the first place?
Start stroking, work towards an edge.
You know, I admire you, I admire what you accomplished yesterday, I sure couldn't stay on the edge for so long if they were telling me to rub my pu.. anyway... You know what I mean? There's no shame baby.
Get on the edge. Stay there.
I know you want to, badly, it's ok. Just cum for me. For Mistress Charlie, pump that cock. Shoot that load. Do it for your mistress. DO IT.
