Thanksgiving. I had been busy in the kitchen all morning, getting everything ready. Lisa had been in a foul temper all week, and I hoped that a good dinner would help to improve her mood. Since last Friday, I have been on her bad side when I made the mistake of laughing at her when she got splashed by a passing bus on our walk home from classes.

"You will pay for that!" she said in a even, cold tone that left chills racing up and down my spine. I followed her home, silent and respectful, wishing that I could just disappear.

As soon as we got inside, she turned and ordered me to strip. I shrugged off my wet clothes, dropping them in pile at my feet. Lisa returned, holding a leather belt and a small empty jar. Behind her, Casey, her 2 year old Shepard Collie mix followed her.

As soon as he saw me nude, his cock began to swell and grow. I have been having sex with him since the third week of Lisa moving in with me. Lisa has made it clear that I am to serve both of them at all times. I am allowed to let him fuck me, usually 2 or 3 times a week.

Whenever I see his cock hard, my standing orders are to suck his cock till he cums. Lisa always decides whether Casey is to fuck my bitch-pussy (her name for my cunt) or my slut-ass(ditto). She enjoys the sight of Casey's cock tied with my ass. By this time, any time he sees me nude, he gets excited.

"Get on your knees bitch!" I dropped down, raising my ass without being told. I felt her hands travel over my asscheeks, stopping at my asshole long enough to stick her forefinger in to the second joint. I moaned at this sudden invasion. She continued to thrust her finger in and out, lighting the fire in my ass and cunt. Before long, I was rocking my hips, eager to get every bit pleasure I could from her finger.

"Like it whore?" I nodded, a truthful answer as well as the only one she would accept. Casey came over and stood in front of me, 2" of red cock sticking out of his sheath already.

"Stroke him till he's hard slut!" I reached out to fondle him, watching his back arch as I wrapped my fingers around his swelling cock.

Without warning, my ass exploded in pain as Lisa brought the belt crashing down on my upturned ass. Casey jumped at the sound, slipping from my grasp. Quickly, 9 more blows struck my bottom. Finally, as I lay one the carpet sobbing in pain and lust, Lisa brought Casey back over.

"Suck him. Don't swallow, fill this," she said handing me the jar. I scooted over to him, opening the jar as I went. Casey let me stroke him till he was hard again. As his cock emerged I started to lick the surface of that red-pink cock, slowly taking more and more in my mouth. Almost immediately, he began to shoot little spurts of precum as he started to hump my face.

As I sucked and licked, I felt Lisa's fingers rub the welts on my ass. I moaned, sucking harder. Lisa's fingers found my clit and started to tease it mercilessly... Casey's knot began to swell and the jets of precum became more frequent. I had to spit into the jar. finally I grabbed his cock behind the knot and squeezed rhythmically as I bobbed my head back and forth over his cock.

I could hear him make little gruff growls as he started cum, jets of semen filling my mouth. As I spit the mess of saliva, precum and cum into the jar, Lisa's fingers slipped inside me and rubbed my g-spot while pinching my clit with her other hand. My orgasm crashed down upon me with the same force as the belt earlier.

This set the standard for everyday since then. Each morning, suck Casey, collect his cum in the jar which Lisa kept in the fridge. Lisa delighted in not allowing me to brush my teeth before class, ensuring I would taste Casey until I ate lunch, my breath smelling of his cum, ensuring I would avoid speaking with anyone. Every evening, the same act repeated to her satisfaction. By Thursday, the jar was nearly full. Casey would follow me around the house, his cock sticking out and ready for his next "milking".

At lunch, I was busy making the dressing for the turkey when Lisa came into the kitchen. "Have you eaten yet" she asked?

"Not yet," I replied.

"Strip bitch," her voice assuming it's command tone. 8 months of training took over and I hastened to obey, right there in the kitchen. Lisa walked out leaving me there frightened and excited. When she returned, the sight that I saw made my knees go weak with desire. She was naked except for her 8-inch strap-on. Without saying a word, she pointed to the floor and I sank to my knees. Reverently, I reached out to stroke her "cock". She grasped my hair, forcing my head back.

She guided the dildo to my lips as I opened my mouth. Without missing a beat, she began to thrust into my mouth, long deep thrusts that forced me to deep-throat it or risk gagging. She continued, long strings of spit dripping off my chin, wetting my tits. Soon, my lips were puffy and bruised, the force of her rape making them go numb as my cunt seeped wetness down my inner thighs.

"Get down," she ordered. Within seconds, she was buried to the hilt in my cunt, fucking me with brisk, hard strokes. I moaned and gasped with pleasure, rocking back to meet her thrusts.

After about 5 minutes of this, she pulled out and had Casey mount me. She guided his cock into my pussy and BAM he started to fuck me with hard jabs that took my breath away. I was so lost in pleasure, I never heard the can opener. All I know is that next thing, she had set a bowl down in front of me, and was emptying a can of dog food into it.

As Casey filled my pussy with 6" of hot dog dick, I watched with slitted eyes as she poured the contents of the jar of cum into the bowl like some kind of gravy.

"Eat it!" she commanded.

I tried to lick at it but Casey's hard thrusts soon pushed my face into it as I ate. The shame and humiliation were too much and a powerful rolling orgasm stole the next few minutes from me. During that time, I finished the dog food, Casey came in my pussy and dismounted me, and Lisa removed the bowl. I don't remember any of it.

As I knelt there, cum dripping from my well-fucked pussy, Lisa asked," So are you going to laugh again, Robyn?"

"No Mistress," I whispered too exhausted to speak.
