Busted!

It was a Thursday afternoon like any other. We were in Ava's room, on her bed naked and well into a session of heavy petting. I was on top of my sister, finger her tight wet pussy, and just getting ready to enter her when...

...the bedroom door flies open!

We are both nearly scared out of our skins as the wood door smacks back against the door stop. Both of us scramble to cover our nude bodies with our hands.

"I told you! I TOLD YOU!" My mother cries out. "I told you they were up to something!"

My father's hard eyes look at both of us before locking on me. Ohhhhhh shit!

"You little piece of SHIT!" He bellows.

He takes two big steps across the room and lifts me from the bed with one hand around my throat. Remember all those shortcomings I talked about? My father had no such issues. At well over six foot tall and two hundred pounds of lean solid muscle he was a physical specimen. I grab his flexing forearm with both hands as he holds me up on my tip toes. I can see he desperately wants to pull his other hand back to punch me straight in the face. He'd knock me the fuck out without a doubt.

All I can do is hang there and gurgle.

"Daddy no!" Ava pleads. "Don't hurt him!"

"You shut your little whore mouth you fucking slut!" My mother snarls with rage.

In all of our twenty years we had never heard our Mom talk like that! Angry did not even begin to describe the emotion in our parents in that moment.

My Dad narrows his eyes and seethes. "I ought to kick your god damned ass."

"...glllrrppp..." Is my only response. I honestly began to worry that he might **** me to ****. I pull away but he holds me firm.

Ava goes to cover up with a blanket but my mother tears it from her hands. "I found one of your used rubbers poking out of the trash the other day. I knew by the size it had to be your shrimp dick brother's."

OUCH!

She continues. "And with the way you guys have been acting lately... You two ought to be ashamed!"

"We are! We are!" Ava says desperately. "We won't do it again. I swear."

"Ohhh trust me!" Mother sneers. "When we're done with you two you won't want to!"

When they were done with us?

My father takes in a big breath of air through his nose. I watch his broad shoulders rise then fall. He blinks a few times the slowly lets me down and releases me. He lowers his hand but his furious eyes stay locked on me.

Our Mom moves to the corner of my sister's bed and clears a few things from a chair that was there. "If you two little degenerates want to keep your room and board along with that free tuition we're giving you, you're going to do exactly what we say."

"Mom, Dad, please..." I start to say.

"Shut the fuck up you sorry excuse for a son." She snaps. "Get over here and sit down!" She points down to the seat of the chair.

Ava and I glance at each other, both of us wondering where this was going.

"Do you want to get kicked out?" My mother warns.

"No Mom!" Ava says. "No. We'll do whatever you say."

"Damn right you will. Now get over here Aiden!"

I hesitate a moment longer. Seeing my father's still trembling fist I decide getting some distance would be a good idea. I nod and hurry over to sit down in the chair. With my right hand I cover my shame.

My mother pulls my arm away. "Oh no, no, no. You two just love being naked so much around family. We wouldn't dream of denying you." She turns and points at Ava. "Hands down. Show the family your filthy whore body."

What happens next makes my jaw drop. Dad begins to unbutton his his flannel shirt and Mom says. "You two want fuck around with family? Let's see what you got."

"Mom!" I gasp.

"Shut the fuck up you pencil dick geek." She barks as she too begins to unfasten her blouse! "You two started it, we're going to finish it."

They were bluffing. They HAD to be bluffing!
