Hi, thought I'd add another story from my past experiences....you may have read some of my other stories from the same partner... It was a work party, she had been at work and was out in the evening at her firms party...they were a large company and often had large themed parties...I think this one was set-up as an amusement park. Earlier in the day I had received some vague txt about the junior in her department, I knew she seemed to have a thing for him as she had often joked about getting him to help her with tasks, which seemed to involve bending over to being up a ladder.... lol As the night wore on I was txting to see how she was getting on...she was obviously drinking a lot which was obvious from her txt back....she had said that she had danced with the junior (at least 10 years her junior as well lol) and things had gotten quite close and heated, pressing herself up against him and giving him a little snog...she said it was also obvious that he was interested from the bulge in his trousers.....that she had not really helped much with as she said she had brushed her body against all the time they were dancing.....so before the txt came I already knew what was coming..... "Can I stay out and fuck him?"......well the fucking was never an issue, that was just want or animal desire.....but the staying out bit was.....we had an agreement that it had to be at ours....but in the end I agreed, how could I not, and (with a couple of conditions) off she went to book a room and see if she could bag him... She txt to keep me updated and to tell me where she was.......and then, a little while after they had arrived at the first condition was fulfilled....waiting in bed with my cock in hand, the phone rang, (the first condition being for her to secretly call me during sex and leave the mobile on the side for me to listen) which I answered to hear the sound of her having one of her very vocal orgasms...followed very quickly by a second...so I knew these were not the first.... This was soon followed by the junior talking dirty to her (she loved that) calling her a slut and telling her to "suck his cock" which from the sounds she duly did.....whilst she was doing this he was telling her how he was going to "fuck her hard like the slut she was".....I was as hard as he obviously was and wanking slowly myself..... Soon I heard him telling her to get on her knees as he was going to fuck her hard....very hard I was hoping, and I nearly forgot and shouted down the phone for him to "fuck the bitch really hard..." Then I heard the sharp intake a breathe as he mounted her and started fucking her doggy style.....I could hear him slapping hard against her ass, and hear her egging him on...."fuck me, come on fuck me harder....is that all you have....harder.... fuck yes, that's it....fuck yes...." By now it sounded like he was pounding for all he was worth and I was yet again amazed by the stamina of youth...after what seemed like an age of pounding into her she was egging him on to cum in her....which seems to push him over the edge as he gave one final large slam into her, gave a big groan and shot his load....... Annoyingly it seemed that last effort knocked the phone off as well as it sounded like it bumped a few times and cut off.....luckily about the same time as I shot my load too...... About half an hour later the phone rang again (I expected it to be her saying she was on the way home - condition 2) only when I answered the phone it was to the gf in the throes of passion again....I could here him fucking her hard again and slapping into her ass doggy style....but from the yelps and groans she was making I knew he was fucking her ass..... Instant hard on for me as my cock virtually leapt into my hand....she was grunting and groaning as he was really laying into her ass....saying how it hurt and she fucking loved it.....and asking him on to cum in her ass.....fuck, that was enough for me as I came again.....he was still going at it, ploughing on in for sometime until with another loud groan he shot his second load up her ass....... perfect! A couple of minutes later she spoke to me telling me he had gone to the bathroom to clean up.... "how did you like that little bonus darling" she said....."probably as much as you no doubt" I replied....lol With that she said she was going for a shower and would be home, and about an hour later she was snuggled up next to me no doubt dreaming of another ass load full of cum...
