I was comfortable she would be fine as she was with three others all whom we know very well and all four are married. She came back smiling and happy but there was a hint at something that went on while they were away. My wife was her normal loving self and sex was good but I was aware at first that she seemed not only looser but that there was just a hint that she didn't reach the level of enjoyment she had a few weeks ago. I was suspicious but let it go as she seemed content. It was May when Katie mentioned she'd had an email from the Grand Canaries then told me that the son of the owner of the house they'd hired was hoping to visit England this summer and could we put him up for a few days? I started by making weak excuses but when she shot those down in flames I was struggling to get out of it so simply told her ok. I didn't know the kid and the thought of some teenager getting under our feet didn't seem an attractive proposition. Katie played it straight and simply told me that she understood about not wanting Rashid in our hair all the time so maybe if we told him that he could only be around for a short while it might be ok but we'd have to avoid hurting his feelings so maybe tell him we were going somewhere the week after. I had been cornered so just let it happen. I decided that if we had to have this kid in our house we'd try not to stop doing what we usually do and he'd have to expect to be left by himself. The Friday he arrived I went to meet him from the airport and got my first view of the boy. He was much older than I'd expected, Katie had made him sound twelve and gangly but he was almost seventeen and while not very tall was quite stocky. We'd decided book a restaurant for that evening, he was meant to be meeting friends and family the next day anyway so I was hopeful he might stay out. Sunday we would have lunch in and then he'd go first thing Monday. I drove him from to the airport as he chatted brightly about how grateful he was and how it was his first trip to England and he seemed totally relaxed about us. Katie was looking really great; she wore a short dress and heels and had her hair up making her look really beautiful. She greeted him with a hug and we had what was actually a nice evening before going for a meal. Once back from eating we sat up chatting only he begged our leave and went to bed not too long after. We were in our bedroom a while later and asleep fairly soon. I have no idea what woke me possibly a noise made by Katie, I can't be sure, but as soon as I was conscious I could hear her occasional grunting; she wasn't in our room. I got up and tiptoed to the bathroom where I secretly watched her as she used a shower gel bottle to bring herself off. I considered making myself known but knew it wouldn't achieve anything apart from Katie's embarrassment but I was only too aware what had turned her on so much to do this. In the end I went back to bed and sulked before I heard her return. The next morning she took my cock in hand and played with me, something she'd only usually did prior to sex, except this time she was kissing me as she muttered that having a young virile man in the spare room was quite a thrill. What was I to say? She murmured that she knew he'd appreciated her dress last night because he kept staring at her legs. Then she got quicker and quicker mentioning that it would be interesting to see what he (Rashid) thought of her yellow leotard as I always found it sexy! She meant the one she had occasionally worn on a Saturday morning when she was off doing her music based aerobics which she'd decided was a little too revealing in the end. Now all I can add here was that she made no effort to have sex with me just keep pumping me while she kissed me muttering about her semi-indecent leotard until I came with a jerk and she giggled then her passing shot, as she slipped out of bed, was to give me a wink. Later that morning Rashid got to see her in that very outfit worn over white footless tights and she gave me another wink as she stood sipping coffee, the slightly too transparent material showing her off to the both of us. I could see Rashid eyeing her up and when Katie caught my eye she gave me another disconcerting smile. I left for football upset and I have to admit it wasn't my best game as I slipped from distracted to angry and got a caution for swearing loudly at another player so came home dejected. That evening Rashid was back and after a meal we sat drinking until Katie suggested we play a game which when we both asked what she had in mind she. Truth or dare she replied. I said what; it was a kids game but Rashid said yes, so we did. She decided that we should shake a die and the lowest was asked by the one with the highest number. The first few questions were ok, dumb but ok only eventually she asked Rashid if he had a girlfriend and if he was sleeping with her! He said `of course' and she gave a grin. She chose truth the next turn and Rashid asked her outright if she'd ever thought about dating a black man. Katie gave me a look then a grin and said yes. He then asked when but she grinned again and told him that was a second question. I tried to swing it back to normal stuff with a dare that involved eating a raw garlic bulb and a question about Rashid's education hoping to remind Katie that he was still a boy. I got dared to eat mustard, which I did and suffered for the next few minutes but the game then reverted back with Katie asking our guest if he thought she looked to sexy in her leotard. He replied very sexy but that she could never be too sexy! She won again and got to ask him if he'd ever been with a white girl. He paused then asked her pointedly what she meant by `been with'. My wife gave a grin, flushed a little and added `you know'. Shit! She was goading him in front of me! What was this? "Well actually I have and it was very good." He answered with a huge smile. I had to ask a question of Katie which was bland but then she had a dare from Rashid. "I dare you to wear that leotard again for us!" He suggested and without any hesitation Katie left and was back literally in under a minute in the item this time without tights. She sat open legged on the floor opposite Rashid and I could see him staring at the dark outline of her pubic hair through the stretched material, she had quite a camel-toe. Rashid then got to ask me a truth question, I didn't fancy eating mustard again. "Do you like Katie wearing sexy clothes like this?" He posed. I could hardly say no or say not in front of you so simply replied yes. Next Katie got to ask me a question also. "Would you like me to dress in something really sexy?" I wasn't sure how to respond but in the end I replied. "At times it's fun, so yes." She beamed at me then said `right' and was off again. I felt positively alarmed so tried to hide this by getting more drinks. When my wife returned I was horrified. She wore her all over black body stocking, reserved for the bedroom only, which was fine black mesh so more or less revealed everything. She sat down again and I could see the poppers at the gusset showing her pubic hairs between them while her nipples were clearly seen as were the curves of her breasts. The next question was for me and Rashid asked if I like Katie looking so hot which I resigned my self to answering with a yes but added usually in private. Katie was clearly very turned on, as was our guest because he had a very major tent in his shorts. We were, I feared, going where I didn't want to go but felt as if I'd already lost, so when Rashid got ask the next question he simply asked my wife if she liked wearing that in front of him. She glanced at me then holding my eye contact said yes. What could I do? Call a stop to it, far too late? I just sat and then when Katie got to ask me a question I went for dare, a mistake. "I dare you to let Rashid kiss me!" She challenged. I looked at her then argued that it wasn't really a dare for me but she said yes it was and if I refused, then she'd thought of an even greater forfeit. I wanted to scream at this point but I was not the man I thought I was and so I just nodded. The teenager got up and went to her and she stood so they were kissing in front of me their groins just in front of my face. Katie ground her crotch into the guy for a couple of minutes then they broke and she sat a grin spread wide and simply picked up the die. It was Rashid who won and my wife asked for a dare. He looked at me then when I saw a faint nod of Katie's head he asked: "I dare you to open your poppers!" He pointed at her crotch. My wife seemed to hesitate then pulled the poppers open and her whole pussy and surrounds were exposed as the material shrank away from it leaving a six or seven inch diameter gap. I won the next shake of the dice but Katie lost and asked for a question. I was stuck for a question so in the end asked if she was now feeling cold to which in a heartbeat she replied I'm not cold at all I'm really hot! The implication was clear as was her pussy which was showing her lips distended and moist. I prayed I could win the next question or at least be asked one but it was Katie's to Rashid and he chose a dare. She was silent for a very long time then finally she dared him to get his cock out. Shit! He removed his shorts and then his boxers leaving us looking at his half erect monster. Katie gave an ooh, then winked at me. I was unable to move or speak. It was clear to all of us what was going to happen I just prayed my wife wouldn't be so cruel. The very next roll had Rashid asking and Katie choosing a dare. Without looking at me at all he dared my wife to hold his cock. She was over at his side holding it in a flash. She rubbed it pumped it and rolled it between her hands watching as it grew towards it's inhuman state before she let go and picked the dice again only this time she remained next to him. I was next faced with choosing a question or a dare from Rashid and either was going to end in humiliation but in the end I chose question. "Do you think you're wife could take a cock my size?" He asked a little grin showing. I knew if I said no he'd challenge me and they'd have sex so I said yes. Katie then told us she couldn't possibly take it so I was not telling the truth. She looked at me challengingly almost saying `go on get me to try it and see' but I then shrugged and told her she was right. "Forfeit!" She declared. "Right you have to sit out of the game for the net five throws!" I was speechless as they excluded me: Of course we were more or less at the end now but still. So I watched Katie kiss the man's cock first shake, then he admitted she turned him on (when questioned by her). Third shake he played with his own cock (at her request as a dare) until it was hard and then forth shake, with a look at me, he then dared Katie to see if I might be correct after all. The room was silent then she finally said `ok' and that was it. Katie lay down and the young man came over and began to feed his monster cock into her right next to me. Two minutes later my wife turned to me and stated I was wrong because there was about an inch left outside. Still impaled she turned and rolled the dice again and when he lost and asked for a dare she dared him to have sex with her. He was laughing at the absurdity of this since he was already but after that I just watched as they made love. Katie kept looking at me with a mixture of lust and what can only be described at gratitude as I guess she had been desperate for this and I suspected from the way they'd acted that evening she'd already had sex with him on that holiday. I endured watching for five minutes then went to leave but my wife clutched at my arm and held tightly making it transparent she wanted me there so very reluctantly I sat back down and waited for another ten minutes until Rashid yelled and I saw his massive balls contracting as he pumped copious amounts of cum in my wife. When he pulled out I saw her gaping sex with what looked like half a pint of fluid sliding out as she lay; her vagina open towards me. She simply looked at me and gave a broad smile then told me thank you. Rashid left us then and with a gesture Katie invited me to her. I got close and she pulled my lips to hers then murmured that she loved me so much and that I was so special too have allowed her to do this. I wanted to add `again' to that comment but I wasn't completely certain so said nothing. We went to bed and she sucked me until I came not offering sex, which given the size of his cock was just as well; close up I'd realised his cock was the size of my wife's arm with fist closed. Around three or four in the morning Katie got up gave me a little kiss and slipped next door. She was still in bed with Rashid when I got up the next day. After that she began to have sex with Rashid more openly. That day they disappeared to our bed in the afternoon and that night, after she'd given me oral sex when we first got to our bed she slipped away and woke with him. She was having sex with him when I got home from work the next evening on the floor where he'd taken her Saturday night, she even waved at me over his shoulder before her feet curled as he gave her an orgasm. The `few days' turned into weeks and during that time they must have had sex twice a day every day. Sometimes she would return to our bed others not but always she was flowing with the phenomenal volume of his cum which she confessed one night could probably fill a tea cup there was so much of it. Eventually she stopped even starting off in my bed and then when I finally ventured to ask when Rashid was leaving, my wife gave a big grin and admitted he was enrolled on a college course locally and with luck he'd be staying for three years! I eventually threatened to throw my wife out or just leave her with Rashid but frankly I was past the point of caring anymore However the very next night three men appeared at our door and after Katie let them in they hit me a couple of times then warned me not to leave my wife or else. Like I said I'm no macho hero so I caved in fairly quickly. Far from feeling guilty about what happened to me, Katie flaunted her sexual promiscuity in front of me after that at every opportunity. She insisted she and `her boyfriend' have the main bedroom because the bed was better for fucking but still got me to sleep in the same room several times a week usually when they had sex just to rub my face in it. She went out with her lover quite often now and even invited a friend and her husband over for dinner with her and Rashid while I sat upstairs. I crept down later to see Rashid fucking the other woman while her, passed out husband, slept on the sofa. I had no idea if he was drugged but the woman was on heat so I'm fairly certain she was. Rashid seemed to be using Katie to meet other women and along with his friends they would worm their way into their knickers. Some it appeared they fed drugs to while others they were able (like my wife) to seduce seemingly without any problem. Eventually after six months or so I'd seen a score of women used by this kid and several by his older friends as well. Two even turned up for evenings of sex periodically despite both also being married. Katie had sex with a number of the men so eventually it wasn't only Rashid who used her so regularly she would let any of five men have her as they wanted. One evening she even left her sister and husband with me to go upstairs and screw two of the guys only to my absolute consternation she had no qualms; drugging them, then watching cruelly as her unconscious little sister was taken by three large black guys knowing full well she wasn't even on the pill. Katie had become a genuinely despicable person and enjoyed helping to ruin countless women: She witnessed her best friend Chris used several times when drugged as was her sister Libby, only poor Libby ended up pregnant and it cost her as her husband walked out and her friends simply didn't believe that she'd been completely innocent. Eventually I confessed to Darren, Chris's husband who actually thumped me when I told him of Katie's malevolent activities but then a few days later he came to see me apologised and told me he'd suspected something was happening then asked if we could join forces to deal with the `threat'. At Darren's suggestion we persuaded my brother-in-law to come on board and the three of us worked to discover who Rashid's friends really were and how dangerous it might be if we pulled the plug. As it turned out two of the men who used Katie all the time were in the UK illegally and another one of them was clearly peddling drugs to pay for his college fees. We informed the authorities and within a few weeks all had been arrested. Since I'd not been mentioned I was also detained and questioned about Rashid who they knew about but suggested he was running a brothel and then it dawned on me that he'd been occasionally charging men to use my own wife! Katie went at me like a wildcat when I got home telling me I was a bastard for trying to break her up from her lover. I said it was nothing to do with me and then told her what the police had said to me which she called me a liar and I had to withdraw to the spare room to avoid her anger. She had herself been questioned but chose not to believe them either but eventually when she was interviewed a third time she realised the truth of it and worse that she was recorded as being a hooker. She finally admitted she had an idea that Rashid was slipping something in her drinks but frankly she knew she was hooked on whatever it was so let him. After this we all tried hard to help her out and she then went through hell coming off the drug and at times she begged me to try to assist her get something. I did what I could to keep her away from anything although just once she slipped out and tried to score thankfully without success. Eventually she began to get over her addiction and after probably four weeks of ups and downs she got to the other side. It was a lucky escape for both of us because Rashid returned briefly one evening while Katie was out with Chris, and asked if he could see her. I told him she'd left me and he seemed to believe it (she'd told him she going to leave and would willing go with him anywhere just before he'd vanished when the cops appeared for the second time) I suspect he wanted to take my wife with him for collateral but in the end he just grabbed his stuff and scarpered. It subsequently turned out he'd used a student visa to get into the country but apart from enrolling he never went to college. It still took a year to clear my name of complicity in his drug and call-girl activities but Katie is forever down in police records as an ex-prostitute as they had proof she'd had sex for money even if she never saw any of it. Two years on we are still together and she has confessed that partly due to drugs she'd been seduced by him on holiday then once he came to the UK she'd had a lot of drugs and sort of lost herself. He sister will never really forgive her even if she had become drug dependent but at least she is back with her husband as is Chris so we have salvaged something at least.
