Fun orgy got better when we got home

when we moved to the city, it didn't take long before we started meeting couples and singles for swinging, one couple we met often and soon started to organise orgies with them and most times 6 or 7 other couples, our two ladies would drop their dress's and get guys naked and Chris and I would grab women and away the orgies would go.
This Saturday night the orgy was at Chris and Sue's house, we were running a bit late, and on entering saw some 25 or so couples in the house, it didn't take long and people got naked and the fun began, I was taken into a bed room by a young lady and we fucked for some time.
Her friend came in, looking for her and helped to get me to cum, they left me to rest, on leaving the room I saw my wife Lyn in the lounge room, she was a mess, 15 or so guys standing around her naked cum covered body, a puddle of cum under her, and guys fucking her hard, in all holes, I watched for a short while, then went to the dining room, well the women were all in a big lesso session, several guys drinking as they watched them,
Half way though my beer, my cock was grabbed and I was taken of to fuck another lady, it would have been a hour or so later that I saw my wife, still going strong, her face hair and cunt white with cum, so back to the dining room I went, this time I got to drink my beer, just, then once more my cock was put to use filling another ladies pussy and this time her ass too, by now my cock was spent, so I watched my wife being fucked and used by the guys for another hour or so.
When all the guys had finished with her, she could not stand, so Chris helped me carry her to our car and I drove her home.
Our 18 year old baby sitter knew we swung, but she woke and laughed seeing the state Lyn was in, helping me put her to bed, Sheila was 6 foot tall and slim, her naked body looked good as always, as she asked me about our night, and I told her the details, I could see she was getting horny as I did.
Then with a twinkle in her eye she told me she wanted me to fuck her, well my poor worn out cock stood straight up, as I started to kiss and work my way down to her smooth snatch, and after licking her tasty cunt, slide my now hard cock deep in first go, and fucked her hard, Sheila had several orgasms before my balls let go, filling her more with stream than cum, lol, but boy was I happy.
Then behind us Lyn said "that looked good", we talked then went to bed, Sheila sleeping between us,
After that we fucked every week, 3 some's and some times just Sheila and me when Lyn went out, it was great seeing her cum filled pussy each time, but sadly she met a guy and our fun ended.
