The wanking timer! Part 3

The loser's cock is wriggling with anticipation! As soon as you read "wanking", your ears perk up. Yes, the next wanking timer is here, my permanently horny loser! I'll set a countdown that you won't be able to see straight away. During this time you may wank your useless cock according to my instructions, slave. As soon as the countdown is over, you may squirt. But you'll have to put up with whatever the mistress comes up with until then... for better or worse.
