My first real Bisexual experience...

Several years ago my wife and I joined a swingers club in another state, the club would have social dances once a month...My wife and I finally settled down and felt comfortable at these social get togethers (we were very nervous..) and we met several nice couples, one couple we met and became friends with (Steve & Lisa) we would invite back to our room and have sex together as a 4-sum, in the same room and same bed, on several occasions the male half of the couple (Steve) would accidentally touch me as he was fucking my wife and I was fucking his wife...
The accidental touching by another man would arouse me very much...! I have had bi feelings ever since I could remember...! I would sometimes jack-off fantasizing about touching or sucking another man's cock...!! For several months my wife and I would meet this couple at the club and have sex in our room...Then one day I recieved a phone call from Steve inviting my wife and I over to their house for a weekend, well I talked to my wife and she agreed...
On the way over to their house I bought a bottle of rum and some coke, when we arrived at their house Lisa met us at the door wearing only a thin dressing gown and you could see her nipples and pubic hair through the material...Once we settled down and made us a rum and coke Steve pluged in a xxx-movie for us to watch, it just happened to be a Bisexual movie with both bisexual men and women...!
Well after a couple of drinks I noticed my wife making a move toward Steve, Steve started to undress my wife as Lisa came over and opened up her dressing gown and pressed her body aganist me and I could feel a sudden twitch in my crotch area...! Lisa led me to an area on the floor where she had made a pallet in front of the TV and layed down, as we started to play around Lisa whispered in my ear that Steve was Bisexual and that he said I turned him on and Lisa said that she wanted to watch him and I together...!!!
I told Lisa that I have never been with another man but I did fantasize about it, but my wife does not know about my bi feelings, she said that after my wife goes to bed maybe Steve and I could get together...?? I thought about for a minute and told her that could be possible...
Well as luck would have it my wife said she was getting very tired (after working all day, sex, and rum and coke...!) she said that she was ready for bed so Steve led her to the bed room and put her to bed, they were gone for what seemed like an hour...! When Steve finally returned Lisa and I were laying on the pallet talking, Steve layed down beside Lisa and started to kiss and lick her nipples so I started to eat some pussy, it didn't take long for Steve to get roman hands as he reached over and started to play with my dick and at that time I became VERY aroused...! Steve leaned over and started to suck my dick as I was still eating Lisa's pussy, Lisa started to shudder from and orgasm as I was licking her pussy and she watched her husband suck another man's dick...!!!
Lisa said she loves to watch two men together it made her horny as hell...So I finally reached down and grabbed a hold of Steve's cock (first man's cock I ever touched) Steve positioned himself to where his cock was right in front of me, it was a nice uncut cock about 7" long and pretty thick...I took his cock in my mouth and begain to suck on it, I could hear Lisa moan behind me as she was rubbing her clit and watching us play...Lisa leaned over and whispered in my ear that she wanted to watch her husband fuck me...!!!! I thought to myself, oh HELL I have never been fucked before and his cock was so big, could I handle it...? Well I was so aroused that I said OK and I then stared to play with Lisa again I layed my head in her lap as she instructed her husband to put his cock in my ass, I spread my legs and Steve pressed his cock against my ass hole and with in a few seconds his cock was inside me...and it felt so GOOD I couldn't believe it...!!!!
Steve started to thrust back and forth and I could feel an orgasm building up inside me, I started to suck on Lisa's nipple's as her husband was fucking me and Lisa had another orgasm just watching us fuck...Then all of a sudden I started to have an orgasm I started cumming all over the place as Steve fucked the hell out of me, when Steve seen my dick shooting cum every where he begain to thrust deeper and harder and I could feel his cock getting really hard as he begain cumming inside my ass...!!!
Needless to say that was the best sex (outside of my marriage) I have ever experienced in my life...!!!
That is when I really knew I was Bisexual...
