Ladies Lunch Mishap

Ok so I really like my husbands man cream so occasionally as a thing for me I'll have him cum in or on my food or I have jar of special sauce made up with it mixed in.
He had to work away for the weekend so made up some special sauce incase I wanted some while he was gone had some the first day and had plenty left.
Second day had some friends round for lunch and went to pop on a dress to try on and show the girls and when I came back they were dipping carrot sticks in mayonnaise or so I thought. Turns out they'd given it a taste test loved it and served it up for us all to share.
I was a little hurt that I was out of sauce now and a little turned on especially seeing it run down Kelly's lip onto her chin and the way she cleaned it up with her finger. The biggest surprise though was when I told them to stop eating and explained what it was they didn't care and carried on eating. Is eating food with cum in it more common than I realised?
