When I was a student at 19, money was really tight. I also had a really high sex drive but boys my age were boring, interested in driking and then a short fuck after. As I found myself fantasising about some down and dirty sex, I came across an ad for escort services. I phoned up and was asked to come in and register. I explained that I would look for some mature guys and was up for most things. I didn't have to wait for long. Two days afterwards, I was asked to go and meet two guys in their hotel suite. They had asked for a whole evening, with oral, fucking and anal. I was a bit scared of anal as I had not done it before, but excited all the same. I wore the required schoolgirl outfit, short tartan skirt, tight white blouse, pigtails and long black stockings. When I got to the room, a guy in his late fifties opened, wearing a bathrobe. He looked me up and down, grinned and pulled me inside. Pushing me towards the lounge, he said how beautiful I was. On the couch was another older guy, perhaps early sixties. He was also dressed in a bathrobe. He held out a glass of wine for me and invited me next to him. A porn film was on the TV, one girl and about four or five guys. They took it in turn to fuck her pussy and arse and it was making me hot too. The other guy sat down on my other side and after a quick introduction I was told to move to the coffee table, bend down and take my panties off. After that, they told me to spread my pussy lips and show them the hole they would be fucking soon. I started fingering myself, feeling quite aroused at having these two old guys seeing right inside my pussy. After a while, I was called back to the couch and saw they were naked now. both had pot bellies, but this did not put me off. Their cocks were magnificent, one was large and veiny, the other one really thick and standing straight up. I knelt down and started sucking on both, alternating between the two. My pussy was juicing up. The older guy got up and went behind me, starting to finger my soppy, swollen pussy. I moaned with delight, which made them exchange some very dirty things about me and what they were going to do to me. I sucked hard on the big old cock in my mouth, while the other guys was lying between my legs now, licking my pussy and arse and fingering both. I loved being licked while sucking on a big hard cock. After a while, they both motioned me over to the big bed. We sat down on it, and they took off my skirt and blouse. Now I was naked apart from the stockings. I lied down on the bed and spread my legs open. I was so horny now, I just wanted to be fucked and filled up with cock, even by these two balding old guys. They fingered me again and sucked on my little tits before flipping me around on my hands and knees. I knew what was expected of me and obediently spread my legs to offer my wet hole. It wasn't long before I felt a big cock being positioned at my entrance. He pushed it in, slowly at first, telling fat cock that I was tight and obviosuly had not had any kids yet. As I felt his cock push in me deeper, I realised I was now being fucked for money and would have to please these two men in whatever way they wanted. the thought, together with the hard fucking from behind, made me cum for the first time. Over the next three hours, I was being fucked by both of them, in the diritest way possible. One would fuck me and the other one would make me suck his cock or play with the empty hole. After fingering my arsehole for a long time, they decided it was time for my first anal fuck. the guy with the thick cock pushed it toward my hole from behind and told me to bear down, like I was taking a shit. It worked, my sphincter opened up and I enjoyed a very dirty and orgasmic arse fuck. They both then took it in turns to fuck my arse and pussy. Thet had obviously taken Viagra and didn[t come for a long time. A few times I felt sore but stopping was not an option. They had paid for their fingers, tongues and cocks to have access to every sinle hole in my body and they made use of that. They used me and I came time and time again. It was the filtiest fucking I had ever had and I my reward was lots of cum in my pussy, mouth and arse. They both said I was the best fuck they had had in ages and said they'd recommend me. I left with a really sore pussy and arsehole, but with 500 pounds in my pocket. It only awakened me to the possibility of having fantastic slut sex and be paid for it. A principle I tried out on my landlord the month after... but that is another story
