Quick intro: I don't write like this much, so if you like what you read, let me know. I could use the encouragement.
I want to see you holding on for dear life. Face screwed up from the strain of not passing out from overstimulation. Neck and chest flushed red, glowing red handprints on your ass, puffy bruised cunt from hours of savage thrusting.
You can barely take his vaginal beating. Your nerves are shredded, your skin is tingling, your entire being hums like a violin string getting plucked. Your pussy has resized to the girth and length of a Pringles can, overflowing with cum. Each thrust produces a loud squelching sound, and causes a fresh ribbon of cream to trickle out. He's dragging half your guts out and cramming them back in with each pump.
The skin of his mighty tool is hot enough to burn your insides. He's blown his nut into you over and over, and he's still going. He's a bull, a god, a King of Cock. Your cum-saturated brain has stopped thinking about enjoying this encounter, and started wondering how to survive it. He's going to keep rampaging you with that fucking cannon of a dick until his mighty balls are finally depleted. It could be days for all we know. He has the stamina, prowess and testicular capacity of a prize breeding stud.
