Nope, six shot a game.

“No way” he answered, looking at her as if looking at an idiot “Six shots a barrel, six shots a game. You shot a bullet, I shot a load. We still have four shots to go”

“Wha...” Lisa didn't have the time to show her rage over this sudden rule that Usher stopped her “I'm already giving you a favour and counting my loads in the six shots. If you weren't a virgin i'd make you get all the six rounds on your own, so don't go all prissy on me” he said as he slapped her ass, the **** reverberating in her filled lower half producing in a ting of pleasure that resulted in a mewling sound escaping her lips.

“Humpf, acting all prim when you're just a slut” Usher snorted and, before she could rebel against his words, he pulled back his hips and slammed forward, the lips she opened to berate him instead letting out a loud moan, followed by many others as the banging resumed, wilder than before.
