She is being chased through the woods by a man she can't quite recognise. He is getting closer and closer, she can't outrun him. He grabs her and flings her to the ground, but before she can scream she wakes up. She lays there, panting, waiting for her heart to calm down.
Finally, she quiets down and is able to sit up, only to realise she is soaking wet. Not just sweat; her cunt is flooding the sheet. Her dream has made her very horny. "This can't be," she thinks. "Why would that turn me on? Yeuch!"
She tries to put the dream out of her mind, but the more she pushes the more the dream pushes back, adding embellishments as it goes. Now he is wearing gloves. Well lubricated gloves. Suitable for fisting her dripping cunt and ass. He was fully clothed in the dream, but now her mind sees him wearing boxers only. And now not even those.
When she sees his cock she gasps. Her hands go unbidden to her breasts, squeezing them, pinching her nipples. His cock is huge, dangling from his crotch. Now it starts to harden and lift. When it is nearing full erection she realises it is by far the largest cock she has ever seen. She wants, no, needs that cock inside her, but can't transform the vision into reality.
She stuffs three fingers in her cunt and rubs furiously. Realising this would never get her where she needs to go she adds the fourth and finally her thumb, pushing until she can make a fist inside, then pumping furiously. It is not until later that she will realise that she could barely get four fingers in last time.
Still wanting, she reaches with her other hand into her toy drawer, scrabbling for something big. Her big butt plug comes to hand; she slides it in her ass as though it was a thermometer. She moves the plug back and forth, in and out as she thrashes her cunt with her fist, but she is still not there as she visualises that monster cock ravaging her holes turn by turn.
