Tell Katherine And Let Her Get the Point

"Katherine I'm going to explode pretty soon if you keep letting me **** your sister's mouth like this," you gasp.

"Please not yet," Katherine suddenly yanks Emma's mouth back off your cock, "Let me have your cum. I want it so bad, please John."

Katherine shoves Emma to the side and gets on her knees in front of you, giving you the puppy eyes as she begs for your semen. You smile and reach down to jerk your cock. Katherine opens her mouth and you tap your head against her outstretched tongue. She wants your cum so badly and you love it.

"Here it comes you little slut," you groan as you spurt onto Katherine's face. She sits there with her mouth open like a good girl before engulfing your cock with her mouth in order to get a taste. She pulls back and you admire her beautiful, cum-covered face.

"Well, now you and Emma are tied 2-2," you say, "but I'm exhausted, maybe we will just have to call it a tie."

A shocked expression crosses Katherine's face - she clearly wants to win. She opens her mouth to say something, but you put a finger to her lips, shutting her up. You have an idea for a tiebreaker.
