Agonising stop - and - go jerk off instructions

Your useless cock wants to be jerked off again? Stupid if nobody else cares, but you already know that, loser. What luck that you're allowed to wank today! According to my rules, of course. You'll earn your wanking licence with one or two CBT tasks, wanker! Your pathetic loser cock will be wanked by stop-and-go (and thus at the mistress's whim). Your loser cock is already wriggling with joy and just wants to jerk off. No wonder, because the mistress is also wearing stockings and nylons on her beautiful legs! There will be a squirt countdown, but will it satisfy you? Only time will tell, wanker slave.
