He does

"FUCK...YES...fill my pussy with cum..." she shouted as Darrell shot his load into her, her walls clinging to his dick as he fired jets of his cum into Katy's pussy for the second time.

"Thanks babe," he calmly tells her as pulls out of her, a few more trickles of his cum disappearing into Katy's pussy as he pulled out of her.

"I hate to interrupt you, Ms. Perry, but your driver has returned," Rick tells her, not really expecting trouble, but not knowing Mark well enough to know for sure.

"Tell him I'm busy," Katy tells Rick, dead-set on finishing her duties as a fuck toy/cum slut for her new hot servicemen friends.

Mark had arrived at the barracks and was told that Katy was there, so he waited for Rick to give Katy his message and then wondered to himself why Katy was still wanting to stay.

"Well Mark, I don't know if Ms. Perry would like me to say this to you, but she's busy doing all of our military men right now, actually," Rick tells him, Mark smiling a wry smile, not surprised at Katy's sluttiness.

But he was also thinking that he wanted a piece of the action.
