Pet companion training is over after lunch once I finish eating his leftover burger and fries from my treat bowl. Mr. Smith removes my collar and bends me over his desk once again.
Just when my fluffy tail butt plug plops out of my asshole Mr. Smith's cock is pressing for entry. I suck in a gasp when he plunges to the hilt without pause. His head digging deep into my bowels as his balls smack forcefully against my pussy. He likes giving it rough up my ass.
I cry out in pain trying to enjoy his perversions. My stretching ass on fire as I try to transport myself to a time when he kissed and licked me there and to the time he made me cum in the bathtub after taking my double virginity just the day before. My clit pulses to his harsh rhythm and my cries graduate to moans.
His heavy body leans over mine, cementing me to the desk so he can whisper in my ear. "Such a good girl. You make a great pet. And you love it when I fuck you roughly, you hear me?"
"Yes, Sir. I love it, Sir," I whimper into the polished mahogany.
The building of immense pressure in my abdomen is interrupted by an insistent knocking and bell ringing at the front door. My heart jumps from my clit to my throat.
While still dragging is cock in and out of me, Mr. Smith leans over and opens his laptop sitting next to us on the desk. He curses under his breath and pulls out of me quickly. I feel empty and fearful. I try to get up to see the screen, but he shoves me back down.
"Don't move." His clothes shuffle as he puts his unrelieved cock away.
I stay put and hear his footsteps leave the office and open the front door. The next sound flips my stomach like a pancake.
"Where is she! What are you doing with my sister?!" Sasha, my twin, shouts and stomps through his front door. All sexual drive evaporates and I'm back at home or school where she always taunts me.
Do I respond? Do I stay put? My body chooses to keep frozen to the desk. I'm angry at her intrusion and embarrassed she might see me like this and make fun of me further. Or worse, tell our parents what I've been doing here and get me fired!
"Just one minute, young lady!" Mr. Smith's voice is coarse and demanding. He never talks to me like that. She must have stopped because he continues scolding her, "You will not walk into my home uninvited, shouting nonsense. If you have something to say to me, we can sit down like adults and discuss things in my office. Follow me, right now."
Their shuffling feet make my heart pound aggressively in my ears and I still can't move. She's going to see me and ruin everything!
"Sally, go put your clothes in the dryer while I talk with your sister," Mr. Smith commands as if this was a perfectly normal situation.
"Oh, my fucking god!" Sasha yells at the sight of my naked body stretched over his desk scattered with the collar and fluffy tail.
I slowly raise my face and avert my eyes. I stand completely naked in front of my sister, but not for the first time. She's seen my breasts and bush before--we've even made out and stuff before on a dare. I bring myself to look at her face, her eyes are as wide as her mouth, and I can tell she's concluded that I'm not a virgin anymore.
She runs up to me and grabs my wrist to drag me out of the office, but I yank my hand away. "Sasha, stop it!"
"Sally, what the fuck are you doing? I found your contract or whatever on your bed! This is like prostitution or something. It's got to be illegal and not to mention perverted!" She closes the distance between us to mere inches and hisses, "He's like as old as our grandpa!"
"Sasha, this is my job! I only do what I want to do so just leave it alone! Please just leave!" I beg her and try to push her out the office door.
"Sally, do as I say!" Mr. Smith's tone is stern but still not as mean as he is with Sasha. "Sasha, sit down and let's talk."
The forcefulness of his voice reminds me of our dad. Sasha talks a big game, but she can never stand up to our father. She takes the seat I sat in when he hired me just last week.
I walk naked through his house to the laundry room and pull my pink dress from the washer and check that it is no longer sprinkled with his urine from my poor aim this morning. Eager to return to the catastrophe that is my sister, I pluck it in to the dryer quickly and hope Mr. Smith can fix things.
When I return to the office, my naked skin covered in goosebumps, Sasha's head is bowed reading something. Mr. Smith sees me and raises his hand signaling for me to wait where I am. I stand uncomfortably with my legs crossed and my arms over my heavy breasts.
"You don't have to," Mr. Smith tells Sasha encouragingly. "But I would bet that Sally is probably more experienced than you are by now. She's definitely a better submissive from what I've seen so far. The way she talks about you I bet your full of defiance and couldn't take orders from anyone."
Her head jerks up and she slams a paper on his desk. "Pen," she spits out. Mr. Smith sets a thick pen in her outstretched hand. She signs the paper and shoves the agreement across the desk.
"Remove your clothes, Sasha." Mr. Smith files the contract in his desk and gestures for me to come forward. Sasha stands and strips in a sexy looking way. I try to take note on how she sticks out her ass and folds at her waist, reaching her toes without bending her knees.
We stand next to each other naked as the day we were born facing Mr. Smith.
"Sally, your sister has agreed to a non-disclosure." Mr. smith sits on the edge of his desk in front of us. "She won't mention anything that happens here to anyone just like you have agreed in your contract."
He gets up and opens a drawer. The desk now decorated with two collars and tail butt plugs seems surreal. What was happening? I look at Sasha inquisitively, but she keeps her eyes on Mr. Smith and a smile plastered on her smug face.
"Sasha is joining us for a pet play date, just for today, so we're extending our time. You know the rules." He looks between us when he says this. "Now, both of you, on your knees and raise your hair."
She giggles and I ignore her. I can't wait to see what he makes her do. How soon she'll break and run away. She'll have to admit that I'm better than her at something--at sex!
He makes her wait, petting my breasts affectionately after securing my collar first. Finally, he puts on hers and shows her the same affection, circling her nipples with his thumbs and squeezing firmly. She exaggerates a moan and I see him roll his eyes.
