Katherine Just Survives

The machine pumps forward, pushing the dildo against Katherine's asshole and pussy. She groans as the machine forces itself into her, penetrating her in both holes at the same time. Her asshole protests for a moment at the invasion before popping open and allowing the toy in, with a grunt of pain from Katherine.

"Oh my god," Katherine whispers as the dildo fills her up, "I've never felt this full before." She's unable to keep herself from groaning again as the machine pulls back and then pushes back in. The dildo moves back and forth, in and out, without stopping. You've started the stop watch, but after only two minutes, Katherine's pussy is glistening wet. She's on her hands and knees, biting her lip as she tries to block out the pleasure. You can't take your eyes away as you watch the teen get violated by a fucking machine, and willingly in order to try and win your made up competition.

Five minutes later, Katherine is seven minutes in and unable to hold back her moans. Her hips push back with each thrust of the dildo into her depths, unwillingly fucking the dildo back. You swear she is on the verge of an orgasm any second now, her pussy dripping wet and her lips red and swollen from the stimulation.

However, the machine keeps fucking Katherine and Katherine keeps from peaking just yet.

"Sir, ohhh fuck, can I please, ahhhh, turn over?" Katherine grunts out in between gasps of pleasure, "My, ahhh crap, knees hur-fuuuckkkk."

You stop the timer. "Yes you can turn around but do it quickly or I'm adding time."

Katherine quickly flops onto her back and positions the machine back in line with her holes. Soon she's getting fucked again, and you restart the timer.

Katherine's eyes are closed now, only a few minutes remaining. You watch as sweat forms on her chest which is reddening as she nears climax.

"Thirty seconds left," you say, impressed that Katherine has managed to hold off so far. She looks like she is in absolute ****, her face scrunched up in pleasure and determination, both trying to overpower the other.

"Ten seconds," you say.

"I, ahhhhh, can't, fuck, hold it - ughhhh - much longer," Katherine says. You aren't even sure she heard you. You watch as the timer ticks down...5...Katherine's legs are starting to shake uncontrollably...4...3...2...Katherine gasps and you can see the orgasm is just about to hit her...1...0.

"Time's up!" you announce.

Katherine's eyes fly open as she hears this. It triggers her and with a look of pure lust, she stutters out, "I'm CU-CU-CUUUUUUUUMINGGGG."

Her legs really start to jerk now as climax rolls over her in waves and waves, made all the more powerful by the effort to hold it back. She's cries out in pleasure, "Ohhhhh fuck!" You watch as her pussy throbs and clear liquid from her coats the dildo. She's still shaking as her orgasm keeps going, on and on. She lets out a final cry and then her head tilts back and she collapses onto the floor, the dildo popping out of her as she lies flat on the ground, her legs continuing to spasm.
