Wow, you're really straining to restrain your cum. It must be so hard being a male slave - I can go weeks without feeling too frustrated at my lack of orgasm. And I don't have balls to be tortured.
I'm going to edge again now, slave. Do you think you can take me? Do you think you can hold this edge with me?
Edge, and hold it for at least 20 seconds. I know I did.
