The boy read this on Mistresses profile, "I want to hurt you to see if the pain that you take will be enough to make you cum."and is starting to believe that she may be right in what she says, with denial and frustration levels the way they are at the moment he is starting to realise that it is more and more likely with the way the boy is feeling.
Add other ingredients like chastity, humiliation, to the equation then, how, the boy feels now he is certain Mistress could achieve this, and probably will !
The boy actually screamed to his self today with the amount of arousal he had coursing through his body, thanking of some of the things Mistress has said she will make the boy endure.!!
