My husband,Mark and I been married for 13 years. We both work out and both are well toned. Mark is 41 years old 6 ft 190 lbs. I am 5 ft 130 lbs, with 36 c tits. Mark tells me he has a small penis but I really don't know because I had sex with only one guy before him and he was the same size. Our sex live has always been very great. Because of my job about 4 to 6 times a year I have to travel out of state for meetings and conferences. It's 2 hours to the nearest airport, I get there 2 hours early to find out my flight got cancel till the next day because of bad weather at the destination. I drove home see a car in the driveway. Our house is on a dead end with woods on 3 sides. There was no lights on the front of the house. I made me way to the back of the house and my eyes almost popped out. I was so shocked to see Marks co-worked, Fred naked behind Mark clearly fucking him. But what really shocked me Mark was in garters, stockings and high heels!. I was mad as hell watching them though the window. As I watched Mark bent over the back of the sofa being taken I started to get wet. I never seen gay sex before. I have seen lesbian sex in the porn films Mark and I watched over the years. I was getting turned on. I undid the buttons of my blouse reached in pulling the cups of my bra down started pulling and pinching my very hard nipples. I lifted my skirt pulling my panties and pantyhose down reaching my very wet hole and started playing with my clit. I got my self off watching my husband getting pounded like a sissy. U could tell Fred just shot a load deeP in my husbands ass as fred stopped humping Marks ass. Fred pulled out of Mark turned away from him. Fred's cum covered shinny cock was hugh. I went back to my car and drove away checked in a hotel room think about what I seen. I masturbated lots that night thinking about what or how I was going to confront Mark. Here was my husband that gave me great sex having a homosexual affair, plus he was a transvestite on top of it. I had no idea he was like that. I got home from my trip acted like nothing happen thinking what to do. When Mark wasn't around I was looking for his stash he is a lot bigger than me so he has to have his own things. It took a week before I found his stuff in 2 boxes deep in the shed that I never go in. He had a few pairs of heels, lots of stockings and garter belts. He all so had a few cross dressing hardcore magazines along with 2 dvd's of cross dressers. I watched one of the dvd. A cross dresser was sucking a big black cock while getting fucked. I must admit, it turned me on watching it. Now it was time to put a plan in action but what?? I put the boxes in our bedroom closet dressed in Marks favorite out fit that Mark likes me in. Black stocking with the line up the back red 5 in heels, red corset. I met him at the door got him naked we went up stairs he was naked on the bed I pulled the boxes out said are these yours?? At first he didn't say any thing just stared at the floor. I said how long u been taking it in the ass. He looked up said sorry Lisa. I sat on the bed with him we talked for hours. He said before we met he had sex with guys and only had a few women. After we married he stopped with the guys till Fred about a year ago. He said it's not something u tell your wife hey by the way I like cock to and like dressing sexy. After sleeping in separate beds for a few days I told him to go get his things and dress for me. At first he didn't want to but I was persistent. He came out of the bathroom in black pumps tan stockings red tiny thong. I was sitting on the bed told him to come over here. I rubbed my hands up and down his legs an rubbed his cock in the thong. I said I see your turned on,his cock sticking out the top. I pulled the thong down started sucking him. I pulled a tape out measured his cock as he watched. He measured 4 1/2 ins long by 5 ins thick. I said Fred's cock a lot bigger than yours. He said yes he's almost 8 ins. I said really I might have to have u watch him fucking me. I took him back in my mouth. I teased him but not letting him cum. every time he was close I would back off pulling hard on his nuts. I said go call your gay lover I want him to fuck me then fuck u. He called as I got naked. Fred lived about 20 mins away. I went over the my night stand got my big dildo that Mark bought me a few months ago when it dawn on me he bought it for him self. I said come on lets go down stairs and wait. I had mark bent over the back of the sofa his ass up in the air. I wet the dildo with my mouth and shoved it in Marks ass. He cried out in pain. U like that don't u. He said yes I said your so gay. I left it in him walked to the big screen TV put the other dvd in. Finely the door bell rang I answered it naked. Fred's mouth dropped. I pulled him in shutting the door leading him to the living room. He looked at Mark then me as I dropped to my knees pulling his clothes off. I grabbed his cock putting it in my mouth. He kept growing and growing. He was big like Mark said. I looked over at Mark watching me suck and said now I know why you like his cock so much. I laid down on the sofa in front of my husband as Fred got naked. Fred started eating my very wet pussy. Fred then stood on the sofa told Mark to get his cock wet Lisa needs a good fucking. I watched mark suck his cock getting it wet. Fred mouthed me and let me tell u his cock hit so many spots. I had orgasm after orgasm, I never in my life had so many orgasms at one time. I said to Fred now fuck Mark. I grabbed a kitchen chair had Mark put one foot on the chair Fred behind him. I got on my knees to get a geed look. Fred lubed his hole I watched as Fred's Cock disappeared in him. For the first time I thought how small Mark really was. He was flaccid and it was like it went inside him. His cock was as big as my thumb. I started licking it trying to get him hard but he couldn't get a hard-on. He then shocked me even thou he was soft cum just started coming out as Fred fucked him. Fred started cumming in his ass. We all rested for a while. Mark now dresses around the house and I buy him sexy things to wear. Fred comes around to fuck me as Mark watches.
