A couple of weeks ago, on the way back from work I went in to a charity shop on my way home. My partner and I had argued that morning and I didn't feel like seeing her right away. The shop was pretty deserted apart from a young man at the counter, who was reading a magazine.
"Pretty dead here, huh?"
"Always is this time of day, towards closing time" he replied, without looking up from what he was reading.
I spent some time looking at the clothes and the CD's. After a while I went to the section round the back where they had a lot of books, and began browsing.
A few minutes later I heard a woman's voice asking the assistant if she could try on some of the clothes. I poked my head round the corner and looked at her. She was very attractive, a tall brunette with long sexy legs. The guy showed her to the only changing cubicle they had, which was next to the counter, then went back to his magazine.
As she went in with the items she closed the curtain behind her, but it only went part of the way across. It seemed like she didn't notice this as she pulled off the dress she was wearing, leaving her in just a pair of very brief panties and matching bra.
I felt my cock stirring at the unexpected sight on offer. I then glanced to the counter and noticed that the young man was noticeably affected also. His view must have been even better than mine. He had put down his magazine and was surreptitiously rubbing the growing bulge in his jeans.
We both watched avidly as the woman tried on various different costumes, giving us a good view of her amazing legs and ass. It seemed that she was totally unaware that we could see her, but I noticed that her nipples had become very erect, through her bra, since the time she first took her dress off, and I wondered if she was trying to turn on the assistant deliberately. I imagine that she hadn't seen me when she came in, and the guy had probably thought that I'd left long ago, so they must have both thought they were alone in the shop.
After trying on a couple of dresses, she then picked up a bikini that she'd taken in to the cubicle. She looked in the mirror as she placed the bikini bottoms against her panties, and then the top part against her bra. Suddenly, she put the bikini back on the hook inside the cubicle, and then, to my amazement, took off her bra.
This was too much for the assistant, who quickly pulled his now very hard cock from his jeans and began to stroke himself furiously. Having shown us a good look of her lovely tits, the woman now turned her back to us and slowly peeled off her panties. I watched with incredible excitement as the guy's cock spurted all over the counter.
The woman noticed nothing and put on the bikini, checking herself out in the mirror from all angles. To my disappointment, instead of taking off the bikini again to put on her bra and panties, she simply pulled her dress back on, and placed her underwear in her bag. She then opened the curtain fully and walked up to the counter, placing the dresses right on the spot where all his sticky jism had landed.
"I won't bother with the dresses," she said. "How much for the bikini? I thought I'd keep it on, as I'm going sunbathing."
The assistant had by now pulled his wilting prick back in his pants, and although he looked kind of dazed, he managed to ring up the sale and give her change. She then briskly walked out of the shop. I felt like following her out and approaching her, as I was still feeling really hot and hadn't jerked off myself, but I didn't want the shop assistant to know that I'd seen what had happened.
Soon after she walked out of the door, he went into the staff restroom, and I quickly made my way to the exit. Unfortunately, the woman was nowhere to be seen, so I walked back to my car, with a raging hard-on. I badly wanted to release the pressure so I drove home really fast hoping that my partner was in a receptive mood.
"Hi Velvet, Wow, you look really sexy," I said, looking at her lying on the couch in her mini skirt and T-shirt.
Before she could reply I jumped on top of her and began kissing her wildly. She grabbed my cock, which had stayed hard all through the drive home.
"What brought this on?" she asked, giving my cock a firm squeeze.
"Well... you know... seeing you... in that outfit... always makes me go hard," I managed to say, in between sticking my tongue in her mouth and groping her tits.
"Bullshit," she said, grinning at me. "I saw your cock sticking out as soon as you walked in the door."
"Mmmm," I said by way of reply, as I pulled up her T-shirt and began sucking on her tits. This always gets her going and her nipples were soon rock hard as she moaned delightfully. Without hesitation, I sharply pulled her panties down and lined up my cock with her sweet pussy.
"Hold it right there," she gasped. "Not until you tell me what happened to get you this excited."
I knew by now she wanted it as bad as me, but she was so stubborn that I knew she wouldn't let me fuck her until I'd told her the truth. I began telling her in full detail exactly what happened. When I got to the part where the assistant pulled out his cock, she grabbed my own and guided it inside her. I carried on with the story as I humped her, finding that reciting it all to her made it even more exciting.
"God you're such a pervert," she said, locking her legs around me and holding onto my ass so that I couldn't move. "What if that had been me, that k** was looking at?"
When she said this my cock suddenly grew inside her, it felt bigger than I had ever known before, and Velvet noticed it too. She spread her legs wider and let me fuck her in a faster rhythm.
"Oh, so that's what you'd like. You'd like some kid to jerk himself off while looking at me, looking at my tits, looking at my pussy."
"Yes, yes, yes," I moaned as I pummelled into her faster and faster.
"Well, maybe I'll go there, and let him do just that."
I stared into her sluttish eyes and came with the longest, greatest orgasm I had ever had, while she screamed out loud, calling my name.
As we lay back, breathing heavily, I told her how much I loved her and how she really knew how to turn me on, pretending that she'd like that to happen to her.
"Who said I was pretending?"
"What? You wouldn't really do that."
"I don't know. When you were telling me about that other woman, I kept imagining it was me, and it got me really hot."
As we discussed it I got another hard-on and vigorously fucked her a second time, promising to arrange it that she could let the kid at the store watch her undress.
The following week I drove to the shop at about the same time as before, when I knew it would be quiet. I looked through the window and saw the same guy there reading his magazine. After a couple of minutes he stepped into the back room and I rushed in and hid in the book section again, where he probably wouldn't notice me.
After a while Velvet walked in to the shop. She was wearing a long, yellow summer dress, which had small buttons all the way down her back. The dress matched her long blonde hair and she looked very sexy and beautiful. My dick immediately got hard at the thought of what was to follow.
By this time the assistant had retaken his place at the counter, and was staring at my horny partner. I don't expect he thought he'd get lucky twice in a week, but I knew different.
Velvet looked up and down the clothes section, finally picking up a dress and asking for the changing room. The guy directed her to the cubicle and went back behind the counter. Just as with the woman the week before, the curtain rail only pulled back part of the way, giving me and the young guy a full view inside the cubicle.
I was disappointed that Velvet hadn't picked up a bikini, so she could take off her bra and panties too, but I figured she must have only felt daring enough to let him see her in her skimpy underwear.
I soon found out differently however, as when my partner undid the buttons of her dress and let it fall to the floor, she was left completely naked. I don't think she had ever gone out of the house without underwear before, and now here she was showing everything she had to a complete stranger.
The assistant wasted no time pulling out his cock. He must have felt more daring after last week's escapade, and quickly fisted his hardening prick while he watched my lovely partner inspecting herself in the mirror while she was totally nude. She was taking her precious time about trying on the dress, giving her voyeur the chance to leer at her tits and ass and pussy as she moved slowly around the cubicle.
By now I had taken my own cock out and was wanking leisurely, hoping she would draw this out as long as possible. Velvet eventually pulled on the dress, but quickly took it off again, her face expressing disapproval at how it looked on her. The guy had still not come yet and neither had I, so I was hoping she would stay like that, with all her sexy goods on display.
Unfortunately, as soon as she had taken the dress off she began to put her own one back on. I was very disappointed at this, having wanted to see the guy orgasm while watching my partner exhibiting herself. He must have felt frustrated also, as he quickly put his hard-on back in his pants, and walked around the counter as my partner came out of the cubicle.
"Excuse me," she said. "I don't really like that dress, but could you do me a favour. I can't seem to do up the buttons on the back here."
Then she turned around, showing the assistant and myself that that her dress was completely unbuttoned. Her back was bare and you could clearly see the cleavage of her ass. I hadn't expected anything like this, and I went back to stroking my cock, thinking about his shaking fingers about to touch her while he buttoned up the dress. I was sure he would take the opportunity to slyly feel up her ass while he did it, and maybe rub his cock against her when he got to the top part.
He didn't get the chance to do this however, as Velvet gave a tiny little shake of her shoulders, making the dress fall in one motion down to the floor.
"Ooh!" she exclaimed. “I’m sorry. I didn't mean that to happen."
The guy just stared straight at her tits, then her pussy. His cock was now straining to get out of the confines of his jeans. She trained her eyes directly at his crotch and opened her mouth with a shocked look on her face.
"Oh my God! What are you going to do to me?"
The way she said it was more of an invitation than a question, and he wasted no time giving her an answer. He bent her over the counter, and released his throbbing cock from his jeans.
"What are you doing? Oooh. What would my husband say?"
"Who cares?" he said breathing heavily. "He's not here and I'm going to give you the shagging of your life."
"Oh no! Stop!"
Despite her words, I knew she loved every minute of it. This was what she had planned all along. After the initial shock that she would go so much further than we agreed, I went back to wanking myself with a frenzy. I was even more turned on than the week before.
As she was bent over, he reached around and grabbed and squeezed my partner's tits. I watched in amazement as he tweaked her very erect nipples, making her moan in pleasure. He then grabbed hold of his cock and shoved it inside her as far as it would go. As far as I knew this was the first time she had ever been unfaithful, and I was very grateful to be here to see it.
"You're a horny little slut, aren't you?"
"Yes, yes I'm a slut. Treat me like a dirty whore."
"You knew I was watching you, didn't you?"
"Yes," she said. "I saw your cock in your hands and I wanted it inside me. Please fuck me. Squeeze my tits. Oooh. Fuck me harder."
I watched as he fucked her fast and hard, listening to her moaning sexily and egging him on to come inside her.
"Wait. Stick it in my ass. Go on. No-one can see," she said turning her head in the direction she knew I would be. I looked into her eyes, knowing that I couldn’t last much longer. He withdrew his cock from her pussy and slammed it into her tight ass. My fist was a blur as I quickened the pace of my jerking off.
"You like taking it in the ass, don't you?" the man asked.
"I do now. Ooh. Don't stop. Cum in my ass."
After a few minutes of his rigorous pumping inside her she screamed out her orgasm. He withdrew from her ass, and let her drop to the floor.
"Oww! Why did you do that?"
Before she could say another word, he stuck his cock in her mouth and fucked her face. Within seconds I saw my partner's eyes widen as his cock exploded, releasing all his spunk into her mouth. She must have swallowed some of it, as he held on to her head, but the rest dribbled down her mouth, over her lips, onto her tits and shoulders. The sight of my partner covered in another man's come made my cock spurt all over the floor, as I watched him treat her like a dirty little tart.
When he had finished, Velvet asked him to get her a glass of water. As he left for the restroom, she quickly put on her dress, found me and dragged me out the door to my car. Instead of driving home I parked in a deserted side road nearby, bundled her in the back seat and fucked her again, feeling the other guy's juices still inside her. She came again and again whispering my name and saying "I want to do it again. In a crowded shop next time."
If I know Velvet, I'm sure it won't be long before she does.
