I kept you begging for a few more minutes before I finally stopped jabbing you with the cattle prod, and by then you're just a sobbing mess. You were exhausted, and your knees buckled as soon as you no longer had to run, but strain on your tits immediately forced you to struggle to stand up straight. Laughing, I began lowering the rope. "Get down on your knees, cunt," I ordered. Your tits were still bound, but it didn't hurt as bad now that you were on your knees. "Keep your knees apart," I said as I knelt down behind you and gave your ass a spank. It was just a light spank, but it was already enough to make you jump. I then reached out between your thighs and grabbed your pussy. You knew what's coming, but exhausted and tightly bound, there's nothing you could do as I began rubbing your fresh, young cunt. I rubbed it gently, even tickled your clit a few times. Still rubbing you, I took my cock with my other hand and pressed its head against the soft lips of your tight cunt. "Are you ready, slut? Here it comes!" I said chuckling and began pushing.

You could feel the head of my cock spreading your lips slowly. They kept spreading and spreading until my entire head was in. I pushed again slowly and gained an inch, then another, until I finally came across an obstacle. I grabbed you by your waist and let you savor the expectation, then I tightened my grip suddenly. "Take this, slut!" I grunt as I gave a deep, hard thrust.
