Just to set the scene: this happened around 25 years ago in the mid 90's. My then girlfriend and I had gone on holiday to Kefalonia, one of the Greek islands and we were staying in a self catering chalet / apartment in the grounds of hotel. I was 25 at the time and she was 22. We sort of had an open relationship - when we started dating she was at Uni a long way from where I lived so we only used to see each other a couple of weekends a month. I'd told her that I didn't want to stop her enjoying the university life so if she met someone out at a club or somewhere and wanted to fuck them, I wouldn't mind. Likewise she didn't mind if I hooked up occasionally while we were apart too. When she did have sex with someone else she would tell me about it next time we were together, and it always got me really horny.

Well, back to the holiday. We had been out to dinner and stopped at a small bar for drinks on our way back to the chalet. It was close to the beach and had a 'pavement cafe' style seating area outside, but with small sofas instead of tables and chairs. We sat on one of the sofas outside, close to a group of local teenage boys who were alternating between chatting and watching the football (soccer) through the window. I asked them who was playing and they told me, we had a brief chat about where we were from and then they went back to watching football. After an hour or so, the football finished and two of them went, leaving three of them. There was only my girlfriend and I plus the three Greek boys outside and shortly afterwards they started chating with us again, so we invited them to sit at the sofa opposite us. Turned out that they were all from a local college and were in their late teens. My girlfriend had a tight low cut t-shirt on and her tits looked great, so they were all looking at them while trying not to get caught looking at them. At one point my girlfriend said to one of them 'hey, are you looking at my boobs' - she was half joking, but he was quite apologetic and embarrased, but I told him 'I don't blame you, she's got lovely boobs', to which eveyone laughed, but essentially gave the three of them licence to look at her tits all of the time. We carried on chatting, but there was a definite change in tone and everything had become a lot more flirty. The bar staff started to clean up and told us they were shortly closing, so we asked them if they knew anywhere to go and they said it was either the bar at our hotel or a taxi into town. We asked them if they wanted to join us at the bar in our hotel and they said that would be great. We all started to walk back and my girlfriend suggested to everyone that we go to out chalet insted as we had a lot of beer in the fridge. I should probably point out that we'd all had quite a bit to drink by that point.

Our room had a lounge area with two sofas and a tv, a kitchen, bedroom and bathroom. The kitchen and lounge areas were seperated by a long breakfast bar. When we got into the room my girlfriend got some drinks for everyone and we all sat down on the sofas and put a music channel on the tv. The flirty conversation continued and they were still glancing often at her tits, so I jokingly suggested she take her t-shirt off so that they could get a better look. My girlfriend didn't take it as a joke and whipped her t-shirt off leaving just her bra, which definitely focused their attention. The conversation was then pretty much all about her tits for five or ten minutes, at which point she got up to get something from the kitchen, stood behind the breakfast bar facing everyone and said 'if you like my tits so much I may as well take this off' and took off her bra then leaned forward so that her tits touched the bar. She was obviously really horny as her nipples were like bullets. She stayed like that for a minute or so, then came back and sat next to me on the sofa.

She then noticed one of the boys had an obvious erection, and she said 'oh, I'm really sorry, did I make you hard'. I was expecting him to be embarrased but he told her that yes, he had an erection and it was from looking at her tits. She then said it was only fair that he showed her his dick as she had shown her tits. He didn't want to show it in front of everyone so my girlfriend took his hand said he could go to the bedroom with her and show it privately. He was obviously concerned that I would mind, and looked over to me to see what I would do. I told him 'go and show her - have fun'. So my topless girlfriend with extremely erect nipples led this teenager with an obvious erection to the bedroom.

I didn't see the following, but it was told to me later by my girlfriend, so in her words:

When she got into the room and closed the door behind them she held both of his hands and put them on her tits, then unzipped his trousers, pulled his dick out and started wanking it. After a short while she took him over to the bed, pulled her skirt up, took her knickers off pulled his hand down to her very wet pussy and slid two of his fingers inside her while she carried on wanking his dick. While this was going on I was talking to the other two and after I'd explained to them that I didn't mind and it was all good fun, they both told me that they were really jealous she hadn't picked them. At some point my girlfriend decided she wanted to get fucked, so puched him back onto the bed, sucked his dick for a bit then went to ride him. He asked her if he should wear a condom but she told him she was on the pill and wanted to feel him inside. She rode him for about one minute then he came hard inside her. They lay down for a couple of minutes then he got dressed and she put a towel around her and they both came back into the lounge, both looking very flushed.

When they sat down, I said to her that they were both jealous she hadn't chosen them, so she took one of them by the hand and led them to the bedroom. To cut a long story short, she fucked him, then came back, then took the last one to the room and fucked him too. Neither of them lasted much longer than the first one, but she said she didn't mind as she was so horny she got off just by being fingered by them.

When she'd fucked all three of them we were all sat down on the sofas and she said that now was a good time to end the night as she wanted some time alone with me. The three of them got up and she pulled her towel down to show her tits then French kissed each one of them in turn while putting their hand on her tits. When they were gone we went into the bedroom and she lay on the bed with her legs open while I got undressed. Her pussy was soaking wet and there was cum on her legs and on the bed. I was harder than I'd ever been before and slid straight into her, no foreplay. While we were fucking she was telling me what she'd done with them and how slutty and horny it had made her feel, all the time while rubbing her clit. She came so hard her tits and chest went red and after I'd cum inside her I lookd at her pussy and it as one of the horniest things I'd ever seen. Twenty five years on I still ocasionally masturbate thinking about that night.
