You examined the amount of cum left in your bottle. You tried not to think about how many guys your wife had to suck/fuck in order to fill it to that point. You knew you would be punished if you didnt have it finished by the time she got back. You gave a reluctant exhale as you brought it to your lips and prepared to take another swig. But the hole in the nipple of the bottle was so small it only allowed a small amount of the thick liquid to seep into your mouth with each suckle. The salty man milk was more bitter than usual this time. Hopefully the batch she was preparing for you tomorrow will be a little sweeter&
