My instructions were clear... 'Remove all the body hair you can, then dress like a girl!' So I did.
It felt so naughty and stimulating to be completely shaved for the first time in my life. My legs and genitals felt so sensitive in the lingerie I was wearing, and my penis leaked precum in to the panties I had on, tenting the material with my throbbing erection.
I could hear the floorboards in the passageway creaking as he approached my room, my heart was thumping in my chest with adrenaline, the blood in my head rushing with excitement, bringing a flush to my face. I was going to be fucked for the very first time up my asshole and I couldn't wait.

I'd spent a bit of time dressing my girly smooth body. Black patent school shoes, white knee length socks, my favorite pair of white cotton panties with matching trainer bra underneath a black pleated miniskirt and white school blouse with tie, all topped with a black cardigan. I was young, smooth and lean, and I thought I made quite a good schoolgirl in my sisters clothes. There was simply no going back now, as the bedroom door opened and he walked in.
'Is your cock stiff?' He asked.
'Yes!' I said.
'Show me.' Came the reply.
I stood from the bed where I had been perched, and lifted the front of the skirt, the bulge in the panties immediately obvious. Pulling the cloth to one side, my erection sprang out and I held it forwards for him to see, proud and excited.
'You know what is about to happen, don't you?' He asked.
'Yes.' I said.
'Good.' He carried on. 'Now, come over here and suck my cock. Get me wet for your asshole!'
He unzipped his trousers and fumbled for his own erection, slowly pulling it free of his pants to show me a larger member than my own, with its long dark foreskin and profusion of hair.
Licking my lips, I walked over to him. Kneeling before his lovely cock, I held its hot wrinkly shaft and instantly took the head of his penis into my mouth as ordered.

I have to say here and now, that I think I was born to be a cock sucker. I love the sensation of another mans penis in my mouth, where I can also taste and smell him as I suck. I love giving oral sex and having my lips parted and fucked by a strong cock. If he'd chosen to just fuck my mouth like a cunt, till he spunked down my throat, I'd have been happy - but I knew this was just foreplay to the main event.
I could hear him grunt with pleasure as I attended to his hard penis, making sure I left as much moisture round his cock head as I could (as I knew exactly where he was going to stick it in a few seconds).
It wasn't long before he told me he was ready.
'Go and put your hands on the edge of the bed, pull up your school skirt and pull down your panties to your knees - I'm going to fuck you.'
Again, I did as I was told.

I didn't have to wait, exposed like he had requested, my smooth balls hanging below my puckered anus, my stiff erection throbbing as it pointed forwards. I then felt a wet finger being pushed inside my bumhole, opening my rectum with his digits. As he grabbed my hips roughly, I guessed what was coming next, and the searing pain of him pushing the head of his penis inside me for the very first time mad me yelp. But there was no let up, he pushed as I protested, pulling me on to his shaft and impaling my on his fat dick.
With a final grunt, his cock was buried balls deep inside my rectum, and then he started to really fuck me.
The pain subsided as I relaxed onto his cock, relishing the fact that I was being sodomised for the very first time. Here I was, having my first anal sex, and loving the fact I was being fucked like a girl up my anus.
All I needed now was for him to spunk inside me, to show me how much he loved me. That's what I concentrated on next. I wanted to milk his sperm from his balls and have his hot cum spurt inside my rectum. That's what he soon did, as he held my hips and thrust up me hard and repeatedly, buggering me till he shot his load deep inside my hole. My first time being fucked like a sissy.
