But how do you get someone to offer up there mouth like that?
Its simple, you dont!
The only mouth that will do whatever you want is yours!
But please dont be discouraged, its perfectly normal for a mouth to be filled with cum,who cares if its yours!
Close your eyes and pout your lips, pretend your a slut with red lipstick and big juicy lips with her mouth open ready to get a load!
You can stroke of course but if you do want to stroke then your mouth must be open and your tongue out alright?
