most providers will not object to letting you do it as long as CIM is on the menu.  

Just make sure that you are not tasting the last guy's cum...

Man of my dreams...

I have certain things I would like to try with a guy, one of them being this. And ummm, no takers as of yet, but definitely on my kink interest level!

And it's an activity I participate in any time the opportunity presents itself!

I am a huge respecter of my partners limits so I'm always careful not to cross any boundaries when it's even  slightly apparent my partner doesn't want to "go to there"

After  swallowing a big load it's always fun to come up and say something like "what you want me to do with this" and the look on their face says it all usually.
