Which girl will be triumpant?!

The motor comes to life and begins shoving the dildos in and out of Alina and Katie. You stand there with your mouth wide open watching as both of these beautiful girls get fucked right in front of you. All you can do is watch. Each thrust makes both of them recoil, their tits bouncing in unison as the dildos change speeds to slow, then fast, then slowing down again. Each synthetic cock is covered in pussy juices from both of the girls. But only one looks like they're getting ready to cum.

Katie face gets flush and her mouth is open as her breathing gets heavier. A bead of sweat rolls down from her neck, over her tits and drips off the tip of her hard nipple. She watches as the huge dildo goes in and out. Her toes curl up and she gasps. "Oh fuck. Oh fuck I- I can't hold it!"

Alina giggles a bit. You realize that Alina has already gotten it out of her system last night and probably has more endurance right now than Katie. Katie had already lost from the beginning. Alina saved your balls by volunteering! You absolutely would have cum by now if a machine was jerking you off.

Suddenly Katie grips onto the arm rests of the seat so hard her nails almost rip into them. She jolts her body upward and throws her head back as she screams in ecstasy and squirts all over her fake cock. "Ugh" you let out a small groan and stagger back a bit. Watching a girl cum is no easy feat for you. Your balls are nearly bursting with cum and the sight of Katie cause a small drop of cum to drip out of your dick and fall to the floor in front of you.

The game is over. Katie is motionless in the seat and laying back. All you can see is her tight stomach and breast heaving with each deep breath she takes in. She's clearly enjoying the after effects of the huge orgasm she just had. Alina walks up to her and stick her tongue out at her jokingly. All Katie does is close her eyes and smile. She's still in bliss. Her one hand massages her perfect breast. The other lazily motions towards her man, who is standing there terrified in the corner of the room. Alina turns her head over and smiles. "Been too long since I busted some balls."

You can barely watch as Alina delivers her merciless punishment to the guy for Katie's loss.
