John was coming to stay in Manchester overnight and had advertised for a submissive girl to meet him at his hotel for the evening. His profile really interested me as it ticked a lot of my boxes. He was assertive, his picture looked good – although I couldn't see his face – and he had a number of positive messages in his guest book that lead me to believe he was reliable and not a timewaster. John was also around 20 years older than me and I am a sucker – literally - for the more mature gentleman.

Online we'd discussed our likes and dislikes and decided on a little bit of role play. I was to be a rather slutty girl applying for the job of John's PA. We were meeting for my "interview and assessment". John had even emailed me a formal letter outlining the nature of the interview, which was fabulous and really set the scene.

As we'd planned, I slipped in to his hotel room to put the final touches to my outfit whilst he had a drink in the bar. I was dressed all in black. I wore my 5" heels – the ones with the ankle straps – black stockings, a six-strap suspender belt, thong, black bra and short-sleeved roll-neck mini dress that clung to me. I had my large DD falsies in place and felt I looked good. I wore my black bob-style wig and lots of slutty make up, including long false eye lashes and ruby red lipstick.

I sent a text to John to let him know I was ready and took a seat as I awaited my "interviewer" to arrive. Obviously I was a little nervous to be dressed as a slut in a stranger's hotel room but I didn't have long to wait before he arrived. I was attracted to John right away. He was handsome and a little grizzled, tall and athletic. He carried an air of authority about him that thrilled my submissive core.

"Do sit down, Samantha" he instructed and I sat on the edge of the bed. He drew up a chair in front of me and looked me in the eye.

"So you're here about the PA job. You will be working directly for me and I will be expecting you to cater to me needs. All my needs." he stated.

"I understand, and this is the sort of role I'm relishing." I replied.

"Appearance is very important. Let me inspect your attire. Please stand up."

I stood as instructed and gave John a little twirl.

"Your dress is very short, Samantha, and I can see your stocking tops, which is something I really like."

"I always like to show my legs off, Sir, and I always wear heels and stockings at all times."

"Excellent. You're off to a very good start young lady. Now please lift your dress so I can inspect your bottom."

I raised the hem of my dress to expose my cheeks and stood with my back to him, my feet slightly apart. Wearing only a g-string left me completely exposed from behind with my cheeks framed by suspender belt and straps. I felt John's hand caress my ass and he murmured his approval. His other hand moved around to my front and he took hold of my clitty through the material of my underwear.

"What's this? Well, Samantha, it looks like you've been keeping a surprise for me. I have to say it is vital that you don't keep secrets from me in your role of PA. I'm afraid this sort of behaviour requires punishment. Do you understand?"

I stammered a reply to the effect that I understood and would take whatever punishment was necessary. John sat back on his chair and ordered me to lie across his knees. My hands and feet steadied me and my ass stuck right up in the air. John proceeded to give me a very good spanking. It was hard but not pitiless and he rubbed me between each stroke. My ass was glowing I was sure of it. I must have had about twenty smacks before he helped me back to my feet.

"Now Samantha, I need to check out your qualifications. I see from your CV that you have excellent 'O' and 'A' levels. Is this correct?"

"Yes, Sir." I replied, biting my bottom lip in anticipation.

"I think you should demonstrate your skills." he said. "On your knees and take out my cock."

I sank to my knees and undid his belt, trousers and fly. I reached inside and pulled out his cock. It was amazing. I'd say it was 7" long but it was the fattest I'd ever seen. My hand couldn't fully encircle it and the bulbous head was beautifully smooth and round. He had big, tight balls and I caressed them lightly as I opened my mouth and slipped it between my lips. I sucked and licked him as well as I could as my jaw adapted to his large girth. I took him deep, trying as hard as I could to get my nose against his pubic hair. I could tell this had turned him on as he held my head still and began to fuck my mouth himself. I was getting very aroused by this but had to concentrate on not gagging as he pushed against the back of my throat.

After some time John pulled me to my feet and kissed me passionately. I helped him to strip naked and he began to fondle my hard clitty which excited me all the more. He turned me around and kissed my neck and I could feel his cock between my thighs – so hot and smooth and hard. John turned me around, kissed me again and then pushed me on to my back on the bed and pulled my g-string down and off. His warm wet mouth devoured my clitty and I closed my eyes and enjoyed the feeling. After a few minutes he manoeuvred himself above me and into a sixty-nine position and he fed his cock back in to my mouth as he continued to suck me. From this position I couldn't resist his thrusts at all. In a steady, forceful motion he pushed his fat cock against my throat. I accepted it and it slipped down – my first deep throat experience and with a bit of a beast of a cock at that. He held it in place. It surprised me that I couldn't breathe but it was turning me on so much. Just as I was about to push him away he withdrew and I gasped for air. Greedily I took his cock in my mouth again and once more he pushed it right down my throat – this time his balls rested on my nose. This continued for a few more times before he withdrew.

"Good girl." he praised and I felt really proud of myself for pleasing him like that. "Now, time to test those 'A' levels. Get on your hands and knees."

I rolled on to my front and lifted myself into the doggy position. John rolled a condom over his cock. I could see him struggling to squeeze the rubber over it. He took a tube of lubricant and rubbed my hole with it. He inserted a finger and I gasped a little. I was beginning to wonder if I'd be able to take that monster but at the same time I was so ready for him to fuck me. His cock head pressed between my cheeks and against my ass hole. I felt it being stretched by the insistent force he was applying and I concentrated on relaxing. In a few moments he breached my tight ring and his cock head slipped inside me. I couldn't help but exclaim "Oh fucking hell." as he slowly pushed his length fully into me.

I've been fucked before and used toys too but never felt this kind of sensation. My hole was really stretched and squeezed John's cock tightly. It didn't hurt as such but I felt on the limit of what was bearable. I was here being fucked by a very horny, assertive man and I loved it. John began to fuck me properly and grabbed by hips to help his leverage. To my amazement I realised that he hadn't initially given me all of his cock and he thrust the full length in to me. I was moaning and crying out with every shove but simply loving the experience. He reached down and began to wank my clit too but the main sensation was centred on that monster inside me.

After some great fucking he withdrew and ordered me to ride him. He lay on the bed and I straddled him. I impaled myself on him once more and began to push myself up and down along his length. My head was spinning as I fucked myself with his gorgeous member. John played with my cock properly and I could feel myself close to cumming. I told him I wanted to cum when he did so we pulled me against his body and kissed me which grabbing my hips again and stepping up his pace. I was his fuck toy now as he drove into me, faster and faster. My nails dug into his back as he reached his climax. John swore loudly as he unloaded into me and I sat up on his cock, pressing my weight down to give him maximum penetration. I grabbed my own cock and with a couple of strokes I shot my cum onto he belly. My ass clamped tight as my orgasm spread through me.

I collapsed down next to him and we both panted hard as we recovered from our exertions. My ass hole was quivering from the brutal assault but I felt so deliciously slutty and satisfied. When we were more ourselves John and I cleaned ourselves up a little. John slipped out for a little while whilst I changed out of my slutty gear but not before discussing when we could do it again.
