After our weekend of fucking, things had to revert back to phone and WhatsApp sex and the occasional car session, usually at lunchtime. Following the effect that talking about another man joining us had on her at the hotel, I started to include it in our chats and also when we were having car fun. It became clear that it was something that left her very aroused and would lead to some very intense orgasms. One afternoon as I stroked and fingered her in the car I started talking about watching a younger man with her and seeing her suck his cock, and then joining in so we could spitroast her. She was incredibly wet and started to ask more about what might happen and how it would feel... I said there was only one way to find out and that we would have to arrange an afternoon at the hotel again and that I would find a suitable guest. Further chats suggested that she was nervous but excited at the thought and she admitted that it was something she'd never imagined doing but was now happy to try, once at least. My online search began and there were plenty of offers. I wanted someone younger, clean, discrete and professional who understood the dynamic and also needed to be well hung! I narrowed the search down to two, and then one - James, a junior Dr who was working some 20 miles away from our meeting place, who loved and had some experience of 3somes and was available on the day we had planned. He and I chatted on WhatsApp and the phone and I showed him some of the photos of her breasts, pussy and stockinged legs. He clearly liked what he saw and the plan was finalised. Sarah was getting very nervous as the day approached but at the same time admitted that hearing me describe him and his cock made her feel very naughty. The plan was that I would meet James for a drink in the hotel bar just to check him out in person, and then I would go up to the room and await Sarah, texting him the room number when the time was right. James arrived and we shook hands and chatted for 10-15 mins as I told him what a treat he had in store, and told him a few little tips in relation to what she liked. he was cool and friendly and clearly couldn't wait to meet her. I went to the bedroom and saw Sarah get out of her car and walk across the carpark, looking as hot as ever in an above the knee dress and heels, with her black stockings and lingerie underneath as agreed. She made her way up to the room and we kissed, she asked "is he here" and I replied "yes...and he can't wait o fuck you" She writhed and said "I can't believe I'm doing this...Am I a slut?" I replied that she only had to do it if she wanted, and that yes she was a slut...." By now my fingers were stroking her pussy through her knickers and she was moaning as I told her he wanted to lick and fuck her juicy pussy and that her wetness suggested she was very excited at the thought of being enjoyed by two men...neither of whom were her husband! She begged me to finger her and as soon as I slipped a finger inside her she clenched her thighs against my hand and climaxed... I kissed her neck and whispered "are you ready for James?" She bit her lip and nodded. A couple of minutes after I sent him the room number, James arrived and smiled at the sight before him. Sarah nervously shook his hand and I suggested he take a seat. I led her to stand facing him and I stood behind her and started kissing her neck (guaranteed arousal) and slowly unbuttoned her dress, revealing her lacy black bra, and started playing with her firm breasts and nipples a few feet in front of James. I then moved hy hand under her dress to reveal her stockings, suspenders and knickers, before suggesting he might be more comfortable if he released his cock. He undid his trousers and slid down his shorts to reveal an impressive erection and Sarah gasped at the sight of it. He slowly wanked it as he watched me touching her up and rubbing her soaking wet pussy through her knickers as she moaned and writhed, clearly further excited by the sight of his young hard cock. I revealed both her breasts and suggested that he and I strip off and suck on her nipples. She leant against the wall and we took a nipple each and licked and sucked. She could see herself in the mirror and I knew how aroused having one nipple made her...having them both sucked simultaneously as James and I ran our hands over her stockinged legs, taking turns to brush fingers over her soaking panties was driving her wild! I kissed her and whispered that she should take our cocks in hand, before we guided her to take one in each hand as we continued to suck her nipples. We then moved to the sofa and Sarah bent over allowing James access to feel her from behind. He was loving the sight of her in her beautiful black lingerie and stockings, her dress up around her waist as he stroked and teased her. Meanwhile I was stood in front of her as I slid my cock into her mouth. James had by now moved his fingers inside her knickers and was rubbing her clit and pushing he fingers deep into her wet hole...just as I had suggested he did when we spoke in the bar. The brought her to a climax and the intensity showed as she moaned and writhed against his hand. I pulled away and smiled at her, saying "I think James would like my little slut to suck his cock" She sat back on the sofa and took him in her mouth...her shyness clearly a distant memory as she looked over at me as she took him deep in her willing mouth. I moved closer and placed her hand on my cock and she took the hint, soon alternating between both our cocks with one in each hand. James was loving the attention and said he wanted to lick her pussy. I suggested she lay back on the bed and spread her legs, pulling her knickers to one side. James soon had his face buried in her smooth wet pussy and he teased and pleasured her for several minutes as I kissed her and talked dirty to her, reminding her how much of a slut she had become and telling her how we were both going to fuck her. She soon orgasmed again and I suggested that James put a condom on and fucked her... He wasted no time and as I kissed her she moaned loudly as he slid his long thick cock inside her. He fucked her on her back for a while before asking if he could have her on all fours. I suggested she move to the sofa and bed over so that she could suck me as he fucked her, but also we could all enjoy the view in the mirror....something I knew she liked. She moaned and gasped as for the first time in her life she had a cock in her pussy and another in her mouth. I ran my fingers through her hair as she sucked me and James held her hips and fucked her deep and slow. She soon climaxed again and he asked where he could cum... I suggested he took his condom off and we swap places....with a view to her taking his load in her mouth as I released mine bareback into her throbbing pussy. She just said "oh my God" and smiled as we swapped places and she felt my naked and very hard cock replace his in her pussy. I built up tempo and he held her head as she took his cock in her mouth. I told him how she had never had a mouthful of cum until a few weeks previously but that she was now a very skilled cock sucker who would swallow every drop. She pushed back against my cock and seeing James reach the point of no return as she caressed his balls and sucked him, tipped me over the edge. As she moaned and gulped as he came in her mouth, my own load spurted from my cock, deep into her willing pussy. She continued to lick his cock clean, as I withdrew and watched my cum dribbling out of her pussy and into her lacy knickers. I reminded her that I needed cleaning and she proceeded to lick the mixture of juices off my cock before going to the bathroom to clean herself up...
