Mommy has caught you again! You're constantly rubbing that pathetic dick of yours, never doing anything productive. You're a waste of space, and she is sick of it. Now, she is going to take matters into her own hands. You're going to jerk off for her, and this better be the best you've got because, after this, you'll never be able to do it again. Mommy is going to take over, giving you a handjob while twisting your nuts. You should feel that pain, that discomfort. Remember, you deserve this!
