Katherine

The flaw in your plan becomes apparent as you consider Emma's question. If you pick Emma, the clear winner in your mind, your chances to get your cock into Katherine's tight pussy would evaporate. On the other hand if you pick Katherine, good but not nearly as good as Emma, it would be a lie, and she would be pissed. So your choice is clear, pick Katherine and get fucked, or pick Emma and don't. You realize the choice was not nearly as hard as you imagined.

"It is a very close decision, but I have to say Katherine is the best," you announce. Katherine snuggles her bare tits up against you and gives you a hug, her hand moving down to stroke your crotch. Oh yeah you think, 'I made the right choice'.

"You stupid dumbshit," Emma yells at you. "I can't believe I got tricked into sucking you off." Glaring at you she continues, "You know who was best you liar. You're just planning on fucking my little slut sister later, and you knew I wouldn't afford you the same opportunity. Now all I have is a wet pussy that needs attention and there is no one here to do anything about it." Looking at you she adds, "Don't even think about volunteering."

Katherine finally broke in to Emma's tirade, "Don't be mad Emma, why don't you let me make you climax. I will use my mouth on you if you like."

Emma said grudgingly, "That would be good, it's the least that you can do. Just make the dumbshit get out of the car. I don't want him gawking at me while we do it."

Katherine looked at me and said, "Sorry, just get out for a minute and let me take care of her. Then we can get onto the dance."

You get out of the car, and try to watch as the girls got to it. You find a semi-clear spot in the steamy windows and looked in. Emma had laid back in the backseat and spread her legs for Katherine. Her cunt is shaved and you can barely see her puffy pussy lips before Katherine puts her face between Emma's legs blocking your view. Pulling up her top Emma releases her big tits from their enclosing bra so she can pull her nipples while Katherine eats out her wet cunt. Katherine is no amateur at eating pussy, they must do this a lot, you think, and she quickly had Emma moaning and groaning as she brings her closer and closer to orgasm.

Your cock was erect and ready to go again, but you resist the urge to jack off, you want to be nice and ready for Katherine later. You peak in the window again and watch as Emma pulls her thick, pink nipples, twisting and pinching them as Katherine licks her clit. Emma explodes in orgasm as you watch, her legs clamping Katherine's head, grinding Katherine's face against her wet twat.

Katherine hops out of the car to rearrange her clothes, and tries to fix her now messed up hair a little. "Jeez, Emma you didn't have to ruin my hair, Katherine complained back to Emma in the car. Suddenly we heard the engine start and Emma took off in the car leaving us standing in the dark parking lot.

Katherine screamed, "God damn it, Emma get your ass back here," but Emma was long gone. She was still pissed apparently.
