How long do you spend licking your keyholder everyday?

The average for him is probably around 30 minutes a day. Granted, there are some days it is longer, some days it is nothing at all. But usually, he spends 15 minutes down there in the morning, and 15 at night. Give or take.
Longest he has ever done was an entire length of a movie. Roughly 1hr 45 minutes.
He complained once or twice but I allowed him to just have his tongue out and say on him and grinded to give him a break. Also a few slaps in the genital region for complaining. But he did ultimately make it through. Few orgasms for myself along the way as well.

 

Unfortunately my wife has a very hard time getting off, so none. I have been locked up for 28 days straight, now, and that was my last orgasm and me fucking her. She uses her vibrator to get off. She loves my tongue, but only her vibrator can get the job done.
