Try to get away!

Not wanting to be stuck blowing her for the whole movie, you pull your head back, getting her cock almost all the way out before her legs tighten around your head, keeping the pink mushroom head of her cock resting on your tongue.

"Ooh, so you wanna play rough huh? I don't mind being a little kinky~" she giggled. With that, she suddenly pulls you back in with her legs, her cock butting into your throat again with a loud GLURK. She holds it for a few seconds, trying to push into your throat while you gagged on her cock, before letting up a few inches. "Y'know, for a slut you have a really strong gag reflex... are you sure it's gonna fit?" she says, putting on a thinking face.

"Mrrphmm HLPH MRPH" you tried to call for help, but muffled by girlcock nobody could hear you. "What's that? Just MAKE it fit? Well if you insist~" she giggled, pulling you back down eliciting another gag. "Come ooon just let me iiiiiin" she pleaded, repeatedly butting her cock into your throat trying to gain entrance. "Just relax your throat like you're trying to... swallow a cock!" she offered unhelpfully.

Finally, with a lucky push her cock slips past your throat barrier, slipping in a few extra inches. Gagging hard, you try to pull back but her legs just pull you deeper. Inch after inch, her cock disappears down your throat, until finally your lips are wrapped around her base, her cock balls deep in your throat. She wraps her right leg around the back of your head, and folds her left leg over her right ankle, securely locking you in place. "Nnnngh, that's more like it! You've got a tight throat Doug" she winked down at you.
