My wife and I were invited through a couple we knew to a private party recently. The women had to dress in schoolgirl outfits. My wife prepared her dress carefully and when she appeared downstairs ready to go, I took a quick intake of breath. She looked stunning. She had on a white blouse, no bra, blue short skirt. Her black stockings could be seen just below the length of her skirt. She also wore a pair of skimpy black knickers. Her hair was in pigtails and her make-up was flawless. We arrived at the house of the hosts and chatted for some time. People were disappearing to rooms. I went to the kitchen to get a drink and when I returned, my wife was stood up chatting to two guys. One of them went behind my wife and started to kiss her neck. I know she loves this and her arm instinctively reached behind his head. He continued kissing her neckand began undoing the buttons on her blouse and eased it off her shoulders revealing her small boobs. I noticed her nipples were very hard and erect. He cupped her boobs and I heard my wife wife let out a small sigh. The other guy undid her skirt and it fell to the floor. He then took down her panties and they led her to a lounger bed. My wife undid their trousers and pulled them down revealing two very large, erect cocks which she proceeded to take in her mouth in turn. The guys quickly took their tops off and eased my wife onto her back. One guy put his cock up to her to suck and the other parted her legs and began licking her shaven pussy. I was enthralled watching and my cock was so hard. I watched my wife getting hornier and she soon began moaning quite loudly. The guys swapped places and continued licking her wet pussy while she eagerly sucked cock. The guy licking her pussy cameup and slipped his cock into her and began fucking her while she still sucked the other guy's cock. He pounded inside her and my wife's moans became louder until she screamed out the first of her many orgasms. The guys quickly changed places and they turned her over so the guy could put his cock in her from behind while she bent over and sucked the other guy. She soon came again and then again, each time louder than the last. The guy took his cock out, turned her again onto her back and she sucked him until he came over her boobs. The other guy soon came over her as well. I have to admit that watching her made me so horny and it gave me immense pleasure. We talked about it afterwards and she said that she enjoyed the threesome experience even more knowing I was watching her. We now have guys around on a regular basis for her to enjoy and I love being there to watch.
