I've wanted Heather to become a slut for a couple of years, so with her agreement set about training her, taking a small step at a time. She's 35, has great legs and a pair of 38d tits which are the first thing most blokes notice. It used to annoy her when men seemed to hold a conversation staring at her chest, but I encouraged her to flaunt them, low cut tops, her tits bulging out, wearing transparent blouses with no bra, going topless on holiday. I like her to go braless all the time, her tits are firm enough not to need one so she only wears one to work. She'd been willing to go out flashing her tits so I moved on to the next stage, going out without panties, then wearing increasingly short skirts, making it more and more difficult to conceal her naked pussy. Going to the pub or out for a meal she either had to stand or sit and quickly cross her legs flashing her cunt as she did. She enjoyed it, her pussy getting wet as she sat, after the fourth or fifth time she parted her legs, deliberately revealing her shaved pussy, getting more daring and exposing her pussy longer each time. We had great sex when we got home. After a while she said it was getting to easy, and she needed another challenge. Although we still went out flashing, further training was now required if she was to become a slut. We are in to a bit of light bondage, just in the house at first, tieing each other up but I decided to push the boundaries a little further. I bought a collar and leash and walked her round the garden after dark, just in her panties at first, then naked. After a few times I opened the back gate which gives access to an alley and led her out naked. Turning left about 150 yards walk to the road at the end, one street light about half way. The first time we went as far as the road before turning back. The next time I took my camera, taking photos of her by the street light, standing naked then crouched with her legs wide, as she held her pussy open, before continuing to the end where she stood at the entrance for several minutes, visible to anyone passing. I started carrying a long T shirt for her, just in case, before leading her across the road one night, to the alley opposite, where I got her to give me a blow job. Eventually over several weeks I led her further through alleys, crossing three well lit roads, sometimes waiting at the side while cars, usually taxis, passed slowing to get a look at her. About half a mile away was a park and by the time we got there her pussy would be soaking, juices running down her legs and I would usually fuck her over a bench, before taking her home with spunk dripping from her cunt. Although we saw people, it was late and dark and they passed some doing a double take realising she was nude others appearing not to notice she was naked. On one occasion she was leaning against a wall masturbating when a bloke walking his dog stopped to watch. I told her to continue and she wanked until she came and he thanked her before walking off. After that we decided she was ready for fucking if the opportunity arose which it didn't for about five weeks. That is until one Saturday night in August. We'd gone out a bit earlier than usual just after midnight, got to the park where I fucked her and were about to head back when we heard a couple arguing. They were standing under a light in the park, he'd got her tits out, skirt pulled up, his cock out of his jeans and wanted to fuck her but she was having none of it and stormed off leaving him frustrated. Watching from the shadows, I told her what I wanted to do and when she agreed I took her leash leading her along the path towards him until we were a few yards away in the light. He was about 19 or 20, cock still out, his eyes almost popping out of his head at the sight of Heather, naked except a collar and leash, her cunt wet with my spunk running down her legs. She stood one hand cupping a tit lifting it to lick the nipple, the other between her legs fingering her cunt “If you want a fuck you can have her” I told him. “Do you want to fuck her?” to which he nodded. Leading her closer I said “Get down and suck his cock then fuck him”. She obediently dropped to her knees, took hold of his average length but very thick prick stroking him fully erect before licking his length and taking him in her mouth as I took a few photos. Her head moving as she sucked his cock deep and slow, me telling her to be careful, not to make him cum. I got down beside her fingering her pussy, keeping her juiced, ready for another fuck, slipping four fingers in her cunt, using my thumb on her clit, whispering in her ear that he was soon going to shag her with his big hard cock. I heard her gasp, then saying that she wanted his cock in her pussy, telling him to fuck her hard. Using the lamp post for support she bent and offered him her cunt, reaching between her legs to frig her clit as he rubbed his prick along her slit. Holding her hips he pushed the tip of his prick in her hole then she gave a loud moan as her cunt stretched round his girth, sliding his thick cock up her. I got several shots, to show her later, of her cunt being penetrated by another man, his fat cock stretching her cunt each time he pulled out and slammed back in. My prick was getting hard again, even though it was less than 30 minutes since I'd fucked her. I got my cock in hand and picking up her leash pulled her head to my erection, pushing it in her mouth to suck. Her tits swayed as he fucked her harder, ramming his cock in and out forcing more of my prick in her mouth until she started to gag. I pulled out just as he grunted he was going to cum and she told him to spunk in her cunt. He gave her three or four hard thrusts, shooting his seed inside her as she frigged her clit faster, close to cumming. He withdrew his prick from her pussy, watching as his spunk ran out. I had been thinking of fucking her up the arse, which always gives her an extra good orgasm as she wanks. Seeing his spunk dripping from her pussy I changed my mind and went for the pink. I slid my prick in to her spunk sodden cunt, having sloppy seconds, his milky cum displaced as she took my cock. Her back arched and she came when I fully penetrated her pussy, shafting her slippery hole, then as her orgasm subsided told her to lick his prick clean of her cunt juices. It was about ten minutes before I came and she took a third load of spunk while the lad had got hard again and came in her mouth. He walked part of the way home with us, surprised that I took her for walks like a dog and that she was naked the whole way. Heather told him she was a bitch on heat and needed to be mated often, inviting him to meet us at the park the following weekend if he wanted to shag her again and to bring some mates to fuck her too. That and what we did on holiday a couple of weeks later are another story. I hope you agree that she has the makings to become a good slut.
