while i can see your point, i think it's worth sacrificing post-cum service to deliver a proper load in these stupid worthless whore's mouths the proper way, which is whenever the man feels like it and without an iota of warning. a true cum slut knows it's her job to pull a man's cum out of his balls with her mouth and knows she has no right to expect being forewarned. plus it's hot to see them wince and struggle as you start cumming all of a sudden and pump their mouths right up full of your semen. i find it makes it much easier to fully drain your balls too. my balls are always completely empty after a surprise cum load delivered directly into the dumb cunt's head.
