Sorry that this took so long.

My heart was still racing as I stood up, pulled my underwear back into place and walked into the bathroom. I used a facecloth to wipe away the cum that had spattered my chest and neck when I had lost control watching my father and my best friend have sex.
I hurried to my room and picked up a memory stick and returned to my father's room. I plugged the stick in and copied the folder onto it. I put the laptop back in its place, gathered up my clothes and walked back into my bedroom. I lay on top of the duvet and put my hands behind my head and tried to process what I had just seen and heard.
I couldn't stay still though, I had to do something. I got off the bed and moved to my PC. I turned it on, waited for the desktop to appear and the plugged the memory stick into one of the USB ports. I opened the folder and noticed that the files were numbered. I had already seen 1 and 2. I clicked number 3 and the file opened. The view was the same, my Dad's bed, but this time it was empty. I heard something, though, it sounded like my father and he sounded angry. Then he appeared, his hand locked around the wrist of my best friend Sammi, this time dressed in a skimpy maids uniform, all black silk and white lace, with lots of petticoats under it. She looked absolutely delicious. I listened to what Father was saying. Apparently Sammi had been negligent in her duties as a maid and needed to be punished.
My father sat on the bed and pulled Sammi over his lap. Her short skirt rose up, baring the sight of her pantied bottom to the hidden camera and my appreciative father. He savoured the view for a minute, and then with absolutely no warning brought his hand firmly down onto her left bottom-cheek. Sammi squealed in pain and struggled but Daddy held her down and proceeded to spank her until her poor bottom fairly glowed under the sheer black panties.
With a quick movement Daddy had her down on her knees in front of him.
"I'm sorry about that, Sammi, but you need to do better." He said, gently stroking her tear-stained face.
My best friend knelt there in front of my father, and reached out her hand to stroke the growing bulge in the front of my father's trousers.
"Why don't you show me how good you can be, Sammi?" Daddy said.
Sammi opened my father's pants and pulled them and his underwear down and off, then dropped her head and engulfed Daddy's cock with her warm, wet lips.
I watched, breathless as Sammi gave my father what must have been a world class blow-job, her eyes locked on his as she slurped and bobbed and lashed his full hairy balls with her tongue. Daddy is only human and he couldn't last long under those conditions.
"Oooohhhh God, Sammi. I'm gonna cum. Swallow my spunk, Sammi. Take it all!!"
The camera was in the perfect position, Sammi had her lips clamped around the head of Daddy's cock and she didn't move it as my Daddy spunked in her mouth. After the aftershocks of Daddy's orgasm had faded, and his cock began to soften in her mouth, she gently licked it clean, then stood, gave him a sweet little curtsey and moved away, obviously returning to her duties.
Daddy sat on the edge of the bed for a minute, smiling to himself, and then he stood up and walked towards the camera, his dick swinging, and reached out.
The screen went black, and I was left with that image burned into my brain, of my daddy's big cock, which even flaccid was impressive. I wanted it, I wanted to feel it grow in my hand as I stroked it, and I wanted to taste it as I licked it like an ice-cream. I wanted to clamp my lips around the head and feel my father's sperm jet out and coat the inside of my mouth so that I would be able to taste him for days afterward. I wanted to be my father's fuck-toy!!
The best way to go about this was to get Sammi on-side a quickly as possible. I grabbed my mobile from next to my bed and dialled the number.
When Sam answered I told him what I had seen and heard and told him that I wanted his help in becoming what he had.
"Thank God, Georgia" he laughed "I was wondering when you'd find the vids. I thought I'd have to email them to you. I've got to tell you that between your Daddy and mine, I'm exhausted. Trying to keep two horny, virile men sexually satisfied is knackering!"
"Well, now I can take some of the pressure off, darling" I giggled.
Cut to Rocky-style montage of Sammi and Georgia, training. God she was hard on me, pardon the pun. I had a crash-course in girls' clothes, from underwear to skirts, then make-up, then high heels. I learned how to use depilatory creams to keep myself hair free. We did a little bit of training with dildos but Sammi thought it would be better if I was as much a virgin to being penetrated as possible, because Daddy would find it even more exciting to 'break me in' as she put it. I learned to suck cock though, because Sammi said that was something every cum-hungry cock-slut should know. I also learned to keep myself clean 'back there' at all times. It took a lot of work, but finally Sammi said I was ready.
She told me to tell my father that I was going out with some friends from work the next Saturday, which I did. I noticed his eyes light up, probably at the thought of Sammi and all the depraved things he could get up to.
