This thread is great. I've often discussed letting my submissive wife drink cum from a glass, and she's done so on several occasions.

The other day we had some friends over for dinner. After dinner, we were all around the table, chatting away and enjoying some post meal drinks, and my wife was being her usual charming self. At one point I got up to go to the kitchen to get some more beverages for everyone, and my wife followed me into the kitchen.

She was super aroused, pressed herself up against me, and said she wanted to drink my cum from a glass again.

I prepared drinks for everyone (two glasses of wine, a few shots of tequila, etc.) My wife took the drinks to the dining room, and I took her glass away to our bedroom. After filling a shotglass neatly with cum, I brought it back to the living room nonchalantly (although I had to be careful to keep my fingers wrapped around the glass, so that no one could see clearly what was inside).

We all moved over to the sofa area to sit down, and I passed the glass of cum to my wife. Then, in front of everyone, she drank the whole thing, as we were all sitting there talking!*—*all the while our guests were completely oblivious.

She gave me this wicked look afterwards, I was so turned on I could have grabbed her again right then and there. Man, what a night.
