Round 2: Crystal

You've had your little break and are well enough rested to begin again. You weren't that exhausted to begin with. You get up and call to the ladies for the next one's turn. Giggles and whispers fill the room, but you can't make-out what they're saying. Although you can guess, because as soon as the next contestant grabs your face, you recognize the hands. They belong to your big sister and there is no mistaking them.

Knowing oral is now in the game, that is where she starts by leading your face to her throbbing erection. No need for foreplay, as she's already at full mast from watching your cute ass get pounded. Doing as you did before, you open your mouth and take her in. She's just as thick as the last one, so you have no problems suckling on the end of her pole or twisting your tongue around it. It doesn't matter she's your sister right now. All that matters is you get that juicy prize waiting inside. It crosses your mind that you're turning into a whore, but it doesn't bother you for long. Not when there is cock to be sucked.

Following your new instincts, you press her member down to the get the right angle for a deeper insertion down your hatch. You push yourself forward and find that she's slightly longer than your first girl, when you reach the end. Trying not to gag is more difficult. You travel up and down her length a few times, before you're gently pulled away from it.

"Hey, why did you stop, sis?" you ask.

"How did you know it's me?" she says with surprise in her voice.

"I know the feel of your hands and the scent of your panties." you respond.

"Oh, that means you've been a bad, bad boy. Let's get you some punishment." Crystal says.

With that, she positions herself behind you and places the moist fuck-pole at your well-lubed entrance. With one slow push, she not just enters, but goes all in. You moan in a mix of pleasure and some pain. And the pain is also somehow pleasant. It feels so right to have her in your colon, that you almost scream when she pulls out completely. The only reason you don't is because she goes back in again, right where she belongs. She lays on top of you, pressing her naked breasts on your back. Having those lovely, soft cushions on your back and a cock in your butt feels so close to divine, that you're leaking pre-cum again. She then starts to move and you find yourself in ecstasy. Only pulling out 2 or 3 inches, then slamming back into you seems to be just what you needed, because you cum on the sheets without warning or restraint.

Your mind is drenched in sexual pleasure. Your thought process stops and all that is left is enjoying the moment that seems to last forever. You don't know how long she kept pounding you. Whether it was a minute, five or twenty, but you don't want it to stop. But all good things must come to an end. Or in this case, "must cum in your end", as Crystal unleashes a flood of spooge in your intestines. So nice and warm, that your only regret is that it can't impregnate you with her superior genes. You tighten your anus with whatever strength you have left in there and squeeze out as much cum as you can in some instinctual hope to bear her children. You don't get all of it in, as she squirts out a couple of shots outside on your cheeks.

You are left to recover with your tongue lolling out and your dick still leaking from your prolonged orgasm.

"Looks like I've won, girls. Sorry to leave you hanging." Crystal says with a laugh.

Hey, that's not her call. You're the judge here!
