She was my spitting image. Tamara, was not only my very voluptuous twin sister.

But she was also my daughter.

See, I'd gone back in time and had a fling with my 18-year-old mother in the back seat of her father's Olds. I promised her a baby - and I delivered - or, rather, she delivered.

My twin.

"What are you staring at?" Sis spat, not even taking her eyes off her magazine.

I just stood there and stared at my daughter/sister. Five minutes before, I was an only child. Now I had a smokin' hot twin and a bottle of free-use burning a hole in my pocket.

Yeah, I was a sick bastard.

My cock was still throbbing from the banging I gave my virgin mother just a few minutes before. But now it rose with a new sense of vigor and purpose.

"I just never realized how...fucking hot you were."

Sis looked up slowly from her magazine with the most disgusted look on her face.


"You're sick, bro. Now why don't you scram and let me finish this magazine."

Apparently, my daughter/sister had a hard edge to her. Did she know I was her father? Was I even ready for fatherhood?

"No," I growled and shut the door, "I don't think I will."

"Aren't you supposed to be with Beth?" She casually flipped a page.

"Who the hell is Beth?"

"Your girlfriend, remember? Geez, I told you to stay away from those drugs!"

I stared at my sister for several minutes, just drinking in her sexual beauty. She may have looked just like me, but she was fucking sexy as hell.

Long legs, large breasts, long, golden hair and a resting bitch face. Everything a guy like me could want.

She was wearing only loose-fitting shorts and a too-tight tee that only accentuated her large breasts. I knelt on the bed behind her and began rubbing her soft, silky legs.

"Eww! Gross! What the FUCK do you think you're doing?" She started to pull away from me, but I held her firm.

"I'm going to fuck you, sis. I'm going to knock a baby in your fertile womb and there's not a damn thing you can do about it."

Tamara started to get up, but something stopped her.

"That's right. You're my cum slut now. Now just relax and let me do what I want with you."

"Why in the fuck am I letting you touch me like this? You're a fucking creep! I thought I knew you, Tom, but something happened. Maybe you hit your head or --"
