My introduction to swinging! Last summer on a few of the hot days in May, my then current gf of 18 came to stay for a weekend with me, the friday night was full of me fucking her in everyway. On the saturday we woke up at 11, my gf put on her bikini after a shower and little shorts over her skimpy bottoms, i never felt to good and crashed on the sofa to watch the snooker. I could see my gf out in the garden on the lounger through the patio doors, her body looking amazing in the sun. After around 20 minutes she came in and said 2 guys on scaffolding 2 doors down were eyeing her up, to which i said ok. She went back out and before she lay back down she removed her shorts but in a seductive slow way to give them a good look, she lay back down and began to rub oil into her legs. With our back door open i heard a whistle, i looked at my gf and she was looking right at the guys rubbing her stomach, i then saw her lift her hand and with a finger beckon them to her. Next thing i see the 2 guys by her chatting, both in their 30's, she has one either side of her and just talking until i see one take the oil and start to rub it in her leg, his hand starting above her knee and going all the way up, the other one sat with his back to me and i cant see one of my gf's hands. i watch the other rubbing her leg, then he goes across her bikini, i then see him pull the string at the side and undo her, she opens her legs as he takes oil in his hand and then begins to rub oil in her pusssy, i then see the other guy turn to his side with a hard on sticking out his shorts with her hand wanking him, he moves forward and she turns her head and takes him in her mouth. By this time the other guy has 2 fingers in my gf fingering her as she sucks the other ones cock, im so hard at this time i have to undo my shorts and pulll them down, as i start to wank over watching my gf with these 2 guys. I then see the guy remove his fingers and go down on her, licking her wet oiled pussy, my gf rises up a bit as she gags on the others cock then takes it out, spits on it and wanks him. She says something to them and then they carry her in to where i'am on the sofa, she smiles at me and says are you ok hunni, as she looks at my hard cock. She comes over and says why you hard hunni?. I said watching you with your 2 friends, she replies mmm you want to see them fuck me?, i said yes. She turns round and said hear that boys, my bf wants to see you both fuck me! as she gets on her knees and they both move towards her taking their shorts and boxers off. She takes hold of both cocks and begins sucking them in turn, gagging and spitting all over them, she looks at me and says mmmm their so big hunni! im loving them in my mouth. At that point i shot my load over myself. She carried on sucking them and said oops he has cum already boys, they led her on the floor both kissing her body all over, one got on her top half, pushed her tits together and begin fucking her tits, the other one back down eating her pussy. Then the one eating her moved and positioned himself at her pussy, he slowly pushed into her, she looked at me and said oh fuck so big, i was now wanking again as i watched him slowly fuck her. She began to moan out on his cock telling him to fuck her faster and she said then you get that cock in my mouth to the other one, she sucked him in moaning on his cock as she got fucked, the guy fucking her began to really pick up speed and slapping her thighs, making her scream out as her mouth was full of cock, she then took him out her mouth and wanked him hard as she looked at me and said, fuck his cock is fucking me so good hunni, filling me right up, by this time my cock was so wet as i wanked, i asked her if she was enjoying herself, she replied, oh yes, im loving it hunni. The guy fucking her then pulled out and went to her ass and began to try and force it in her, she just moaned out oh yes put it in my ass baby, he slowly pushed in her ass and began to fuck slowly the other one then got above his mate and positined himself at her pussy, she said oh fuck yes go on, double me. he pushed in her pussy and then they began to fuck her faster, she looked across at me, her face looking so flush, she said oh fuck im cummimg, they are making me cum so hard hunni. She screamed out as she cum all over their cocks as they kept fucking her, again she looked at me and said oh fuck hunni they feel so big in me and filling me up so good. At that point i shot my second load again all over myself, then the one in her ass said hes cummimg and just kept fucking and filled her ass, then she said hunni, guess what!, i said what? She said i havent took my pill, before i said anything the guy in her pussy grunted and shot his load deep in my gf. We waited with the thought she could be pregnant, but it turned out she was not.
