Lisa Wray, a developer advocate at Google, created a Fifty Shades of Grey text generator. It creates passages that feasibly could have come from the book.
Here's an example:
"'Do you want to play? ,' he growls in my ear, making me tremble. I glance nervously at the bed.
Leaning down, he plants a soft wet kiss on my lips, his eyes glowing with lust, feeling spiraling out from deep within my belly. His mouth is on mine, and my muscles clench deep inside me. Exploring, his skilled tongue invades my mouth. One of his hands moves into my hair, lifting his other hand to cradle my face as we kiss, savagely. My subconscious is purring with pleasure.
His paddle lies casually on his imposing, leather-topped desk. Oh my. His eyes glance over the paddle, and tingling shoots through me.
Abruptly, he shoves me against the doorway. He's pinning me to the doorway using his hips, and all the air leaves my body. He skims his hands along my thighs so that my body rises and fills with my arousal. How does he have this power over me?"
The generator made its way to the front page of Reddit after user by Inri137 posted it, saying "My friend wanted to prove that 50 shades was so basic a computer could write it.. so she did. Reddit I present the 50 Shades of Grey test generator."
"Leaning down, he softly kisses my temple, tasting, sparking electricity ... below."
"'Ready?,' he breathes, his eyes intense, and everything south of my waist tightens deliciously as I tingle ... everywhere."
"My inner goddess swoons and passes out somewhere in the back of my head."
"Fuck, I'm panting already, making me yearn for him, pleasure lancing directly to my groin."
"Without warning, he grabs me by the shoulders, slamming me against the bedpost. I groan, frustrated, making me yearn for him. His fingertips skim up my body gently so that I surrender briefly to the sensation."
"'You were very disobedient,' he breathes. His eyes are softly luminous in the diffuse glow of the lamp, and everything in my body tightens.'Okay,' I whisper."
"All of a sudden, he grabs me by the waist, slamming me against the doorway. It's pleasure overload, making me yearn for him, making me writhe."
"I yelp, and he curls his fingers into my hair, holding my head in place as we kiss. My inner goddess has stopped dancing and is staring too, mouth open and drooling slightly."
