Despite Nat's showing off, no.

You're not too enthusiastic as the game starts up again - considering the last few matches, you're not optimistic about your chances of winning, but you can't just give up either.

However, you start off relatively well... because Natalie's character isn't moving. Natalie herself has started to walk off. You also start to ease off, unsure of what's happening. But she didn't say to stop, did she?

Deciding to capitalize on this, you turn your attention back to the game with renewed vigour! Which was probably not the approach you should have taken.

In your excitement, you jerk your wrists up in an attempt to grasp the controller better. Your vision goes white as the knot crushes against your nub. The jolt of pain and pleasure hits you like a truck, tears streaming from your eyes as you scream through the gag. You convulse, grinding the knot against you again, keeping the crest of the orgasm going as you lie there, struggling to breathe.

You're not sure how much time has passed when you come back to reality. It's hard to see through the tears in your eyes, mingling with the sweat that drenches your body. You're still breathing heavy, struggling calm yourself and get back to normal. You can still feel the knot wedged up inside you, caught between your lips, but not putting so much pressure on you anymore. You're still somehow upright and holding the controller, though.

You try and set off again, more cautious this time. The AI characters are still going - you don't remember if they carry on playing normally despite finishing. Despite this, you still run right off the course at the first corner. You reach a little too hard at the next one, the knot pulling up inside of you, but you stop before you lose yourself outright. You take the next couple even more cautiously, slowing right down and being very careful with your hand movements. You get into a steady rhythm, slowing early before taking each corner, being very careful not to tug at your bindings again.

"Sounds like you're having fun in here, eh?" Nat shouts from the hall. Unfortunately, you're not quite done with your first lap as she re-enters the room, sipping at a glass of water. She seems amused as your progress as she plops herself down next to you. Luckily, the game gives you a Red Hare pickup, and you manage to line a few up on her character as she's sitting down. You manage to knock them off the course, giving her a few seconds of time-out just as she's ready to play.

Natalie finally gets going again, and almost immediately undoes your lapping of her. Thankfully, she doesn't do anything to disrupt you as she passes. But still, her pace is quick. She's nearly finished with her first lap before you're halfway through your second. You'll have to do something...

You try and play a bit more actively again. If you're very gentle, the ropes don't cut too bad on certain manoeuvres. You risk a swerve into an out-of-the way pickup, and luck out, getting a Rocket Robbie power-up that plays the game for you at super-speed. As you're finishing your penultimate lap, Natalie's only a couple of corners away from you, though.

The last lap proves unlucky though. You try and take the first few corners as though playing normally, but pull a bit too hard. You lose focus for a few seconds, trying to get yourself back under control, and end up missing the first plate on a long section of boost plates. You take the second, but skew off to the side, careening of the track again. Then Natalie is right on your tail...

She doesn't pass you immediately, preferring to sit mostly on your tail. You try to respond even harder, which only causes you more discomfort. You take one corner well, but can't help but moan as the rope cuts in deeper. You just about register Natalie laughing. Another corner, and you whine with arousal. You're sure she's just toying with you, but still you can't give up.

It's not until the last corner that she makes her move. It's not particularly spectacular, she just nudges you out of the way, her higher speed and weight leaving you worse off. But instinctively you try and turn back in to the collision, a little too quickly. And after the last few minutes of warming up...

The feeling of the knot yanking up into you again pushes you over the edge. You squeal, dropping the controller as your head falls forward, resting against the pillow below you. It's not as hard as last time, but the knowledge that it's happened in front of your sister is even more humiliating. You turn away from her, unable to look her in the eyes as you hear the end-of-race jingle on the TV.
