His reaction was immediate. He finally realized what he’d done and said a hasty, “Yes, Master!”
“That’s better. If you really want to be my little butt slut, you need to pay more attention.”
“Yes, Master!” He shouted like a boot responding to a drill instructor.
I smiled and returned to sinking my cock into his ass.
“Almost there slut. You’re doing great kiddo,” I said, assuming the same voice he’d talked to me with in the car this morning.
“Thank you, Master!” He was starting to pant heavily now as I filled him.
I met a bit of resistance and paused. So far, the feeling of him wrapped around me so tightly was delicious. I desperately wanted the rest of him around me.
“You know why you have to call me Master, right? Why she isn’t allowed that title?”
“Yes, Master!” he snapped.
“Oh? Why?” I asked.
“Because the Master has a cock!” He grunted now, feeling the weight of my cock inside of him.
“That’s right. I’m your Master, and I have a cock!” I said as I slammed the last inch or so into him, pushing past the resistance.
He gasped loudly as my pelvis was nestled firmly against his ass checks.
“Oh Christ,” he murmured.
“What is it slut? Is it too much for you?” I asked, throwing more evil in my voice. “Should I take it out?” I said as I pulled back a few inches.
“No, NO! Please no, Master. I want it, I want it in me!” He was begging. This wasn’t play-acting; my dad was actually begging to have his daughter’s girl cock in his ass.
“What? You want this!” I said, slamming home and burying myself in his ass.
His only response was a groan, long, low and loud. It made me smile.
“Y.. yesssss, Master.” He finally said when he could speak again.
“So, what now slut? Now that you have my cock, what are you going to do with it?” I asked.
“Master?” confusion was clear in his voice.
“Well, you don’t expect me to do all the work, do you? This is YOUR punishment after all,” I said, still holding onto his hips and grinding deep within him.
“Yes, Master,” he said. Then with some apparent effort, he pulled himself away from me, my cock slowly sliding out of him a few inches before he pushed back and buried me once more.
I had to admit, it was sexy as hell watching my dad fuck himself on my cock. I actually got lightheaded watching his stretched asshole moving back and forth slowly. I wasn’t sure if he was still adjusting to my size or if he was afraid of slipping or what. All I knew was he was going way too slow for my taste.
“What’s wrong slut? Are you tired?” I asked.
“No, Master.”
“You afraid of my cock?”
“A little, Master.”
“As you should be. My cock could tear you to pieces if I wanted to. So, you’re not tired and not afraid. So, what’s the problem? Why are you going so slow?”
“It feels too good, Master,” He groaned, once more pulling himself off my cock a few inches.
“Oh, well we can’t have that now, can we?” I said, grabbing his hips and roughly sinking my dick all the way into his ass in one smooth thrust.
He cried out. I wasn’t sure if it was in pain or pleasure. At this point, the line was being blurred.
But I started moving then. I had a firm hold of his hips as I slid in and out of him. Not those short strokes, either. No, these were full strokes, but I did have the courtesy not to pull all the way out. As I said before, I’m not a monster.
He seemed to take me in stride, easily matching my strokes and pushing back against me.
“Damn slut, you are good. How many times have you had your ass fucked anyway?” I asked, mostly out of curiosity. The feeling of his tight hole sliding back and forth on my cock was driving me insane.
“With one cock or two Master?” His voice was lighter than before. I figured he’d finally adjusted to my size and was getting into it.
“Two? You’ve had two cocks in your ass? At the same time?” I couldn’t believe it. I’d seen it once in a video, but I never thought someone would do it for fun.
“Oh yes, Master. But they didn’t feel half as good as you do!”
“You little suck-up,” I said, my mind still trying to wrap my head around all the things my father had apparently done. I was glad I had a cock now; if I hadn’t, he probably wouldn’t have touched me because I was too tame.
“Thank you, Master. You can fuck me harder if you want. I can take it,” he offered.
“Oh, you can?” I said as I slammed as hard as I could into him. He rocked forward, grunting, but he still took it.
“Yes, Master, I want to be the best butt slut for you I can,” he said.
I tried not to laugh.
“Too much?” he asked in a normal tone.
I slapped him hard on the ass.
“Too much, Master?” he tried again.
“Just beg me,” I said, sweat now breaking out of my forehead. This was work, it was fun work, but still work.
“Beg you, Master?”
“To fuck you,” I said.
“Please, Master. Fuck my ass. Fuck it hard, I like it when you rail me like the butt slut I am. Just use me like a cum dumpster,” while the words could be considered corny, the way he said them made me pound him all the more.
“Yes, Master, that’s it. Pump me, pump your slut. I want it, I want all your cum in my ass. I can’t wait, please, Master, hurry and cum!”
His words lit something else in me that growled. A growl that escaped my lips as I pounded my dad’s ass.
