Fluffing

It's hard....no pun intended....it's hard to suck a cock when he's already excited and make sure that he doesn't cum!!!!
As much as every instinct in your sissy body wants you to grab that lovely cock and suck him till he begs you to stop....you have to fight it off....
He's not here for you....he's here for your wife!!!!
Maybe you'll get some leftovers....
