In your ass

"Fuck me, don't stop daddy. Just cum inside," you said through labored breaths. The pain had returned but was now mixed with intense pleasure. Randy's grip on your arms tightened and he was ramming his fat cock in and out of your ass.

"Fuck...oh fuck..." said Randy and with one last push, he buried into you, every muscle in his body straining to release his seed inside your body. He let go of your arms and collapsed onto you, his whole weight on your back. You could feel his cock still contracting, dribbling out the remnants of his cum. He was breathing hard in your ear, he had clearly exerted himself greatly. The two of you just stayed there, catching your breath. Eventually Randy lifted himself up, put a hand on your back to steady himself, and pulled his cock out of your butthole. In an instant, you felt completely empty. It was as if Randy's cock belong in your ass all along and was just ripped out. Randy rolled onto his back beside you.

"Thanks, that was great," he said. You still didn't have the energy to even move an inch. Within a minute, Randy was snoring in the peace of knowing he got to fuck a girl most guys didn't even dream of. You yourself were fast asleep not soon after.
