I am a foster mom and I am always sure to milk everyone of my boy's balls regularly.
We live in a free use household and my boys know that they can use my holes whenever they need to until they find girlfriends.
My newest boy walked in the other day with a huge bulge in his pants while I was reading a book. I spread my legs and told him to have fun while I continued to read
He shot the biggest load into my pussy and after squeezing the last little bit from his balls I made him lick it up.
I then told him that if he does not behave I will bust his balls even more than I did the first time.
I showed him my pointy high heeled shoe and told him that I would grind it into his balls if he ever misbehaves.
I then reminded him that the free use goes both ways and he can expect me and my friends to use his cock whenever we are horny. He does not need to stop what he is doing but he better have a nice hard cock ready for us whenever we need it.
