Struggle.

Oh, hell no! You aren't about to take this lying down! Certainly not literally. You try a burst of power straight towards her to throw her off balance. But you can't seem to get the leverage.

Heather laughs, "That's cute."

So you try a different approach. Her hands seem like a natural weak point since they only have her grip strength to keep them attached to you. Break through that and she has no hold over you!

...Only you can't reach your own hands up to hers since she's holding you low on your arms. And she puts so much weight onto your arms that you can't move them at all.

Just then you feel something stiff press against your cunt. Seems Heather's been using this time to get herself into position.

"Don't you just love it when they resist?" she purrs.

You almost respond but in the next instant you have about seven inches of hard cock lodged inside of you and the words become a **** moan. Possibly taking this as inspiration Heather takes one hand off your arm and presses her forearm down hard against your throat. You try to scream but only produce a whimper. You try to breath in and feel your lungs get about ten percent of what they're used to. You claw at her arm but don't have the strength to remove it. So you kick out instead.

You feel Heather's weight lighten slightly as you're allowed to kick off the floor again and again, pushing yourself back along the floor. Heather follows, her dick still firmly wedged inside of you.

Then suddenly the pressure on your wind pipe is gone and so is Heather. She sits up on her haunches while you take in a deep breath...of pink gas. You mind goes blank and your pussy goes into overdrive. And so does Heather.

She starts fucking you like a machine, gritting her teeth and grunting against the physical strain. You moan like a porn star, tongue hanging out, even your cock feeling like it will burst as it releases a load into the air.

Heather pauses for a moment to catch her breath and admire her handiwork. Now's you're chance!
