Please... Don't

Eventually my Master bottomed out, pressing up against my cervix within and the backs of my legs without. I focused hard on my bladder, afraid to relax. He could see my grimace, and smiled. He pulled, out listening to my moans and whimpers and then plunged back in, and I could feel myself getting even wetter. It was even more delicious, the pain-pleasure of his huge dick in me and the pain of my bladder and the soreness in my ass was beginning to all feel like one pain, one pleasure.

"Tell me how you need this dick," he said, pressing in again.

"I need your dick Master. Don't stop... fucking me with your cock--Fuck! It hurts so good inside Master... Master... Master fuck me... I'll be a good girl, I promise. I promise I'll be good Master please... Mmm... Master," I pleaded, trying to bounce my hips. "Master, please more. Master please... fuck me with your giant fucking cock," I gasped as he complied, fucking me faster and I clenched hard, but the near miss just made it more delicious.

He pounded into me, flesh slapping slowly at first and then faster, and faster as I began to moan with abandon.

"Ooooh... my cunt, Master. Fuuuck. Oh. Ooooo... Master, yes, please, I'll be good. I'll be so good..."

He smiled wickedly, and stopped thrusting. "Yes, babydoll, I know. You'll be a good little slut for me, won't you? You'll beg for my dick every... single... night."

"Yes, Master, please... I will, I promise," I said, squirming. My pussy throbbed around him, and I whimpered again, this time from pleasure. "Please Master, let me have your cock. Please... please... I want to cum... Your cock is so good... Please, please Master."

He grimaced himself. "Fuck it feels good when you wiggle like that. Fucking slut. Listen to you. Good thing you like my dick, slut, because this cunt is all mine," he said.

Master began thrusting again, plunging all the way into me and making the bed shake. I moaned, after only a few thrusts feeling my orgasm coming. I gasped and panted, holding on, afraid to lose control as Master's cock plunged in again and again, making me moan even more until finally I felt his mouth on my neck, nibbling and I couldn't hold on anymore.

"Oooh," I gasped, before my back arched and I saw stars. I felt Master still going, one, two thrusts until I suddenly felt him cumming too, flooding my pussy with hot, thick semen. My orgasm intensified, and I screamed as I felt the incredible wetness of my pussy and his cock joined by a release of pressure from my bladder.

I caught myself, clenching back down as before the squirt could turn into a true stream of piss. Master winced, pulling out of my tight little pussy.

"Well, that was a surprise. I suppose you've been good enough to use the toilet tonight."
