My cock was still stiff and ready and I decided to pleasure Cathy who was still fucking her ass with her husband's cock as she fingered her pussy. Cathy had already experienced a number of climaxes watching her hot step daughters taking Rob and my cocks up their tight little assholes and the look of lust on her face was beautiful. Peggy had already rolled Terri on her side and slipped next to her spreading her asshole and licking my sperm from the young girls tight butt as Terry slowly licked Peggy's shaved slit making my wife moan and twist with pleasure. I move to Cathy and leaned her back a bit getting down between the spread legs and pulling her fingers from her slippery pussy.
Cathy's cunt was very wet and I knew she would be able to take my cock up her cunt while she fucked Bob's cock up her hot asshole. I guided my cock to her pussy and stuffed my stiff prick up her sopping snatch driving deep into her pussy stretching her cunt and making her moan with pleasure. I matched her plunges so that Bob ad my pricks emptied and filled her pussy and asshole together driving her crazy with pleasure.
Rob came over and stood net to Cathy feeding her his stiff prick and pulling on her hot tits. This was all that Cathy could take and I felt her whole body begin to spasm as a final climax washed over her body.
Cathy's cunt clamped down hard on my cock but I held back still wanting to fuck Sue up the ass. Cathy's pussy and asshole were so tightly packed I could feel Bob's cock throb, thru that thin membrane separating our stiff pricks, as he pumped his wife's asshole full of his hot cum.
Cathy's orgasm lasted almost a full minute and she passed out right after her climax. I helped Rob and Bob lay her down on the mat her asshole dripping with sperm Bob had shot up her tight pink butt. We rested for a minute watching Terri, Sue Peggy and Pat as they pleasured each other with their mouths and fingers. My cock was still stiff and ready and Bob told Rob and I to do the girls again. I wanted to feel Sue's tight asshole massaging my cock and went over to her and Pat and told Sue to get ready for her second round. I helped Sue to her knees and told Pat to slide under Sue and lick her cunt while I ass fucked Sue. Pat's eyes displayed her lust and she quickly had her mouth on Sue's pussy licking the young girls stiff clit as she fingered her tight pussy. I watched as Rob move Terri and Peggy into a similar position and we moved in behind the teenage girls together. I had Pat guide my cock up Sue's hot pussy first and I pumped Sue to a nice climax while she rested her head on Pat's belly and fingered Pat's slippery pussy.
Rob was just finishing up pounding Terri's pussy to a hot climax as Cathy sat up and whistled seeing her daughters ready to take our cocks again. I had Pat position my cock at Sue's tight rectal opening and I pushed quickly up the young girls hot asshole. Since this was Sue's second assfuck her tight anus stretched out easily and I quickly buried my entire cock up her pulsing butt. Looking over I could see that Rob had done Terri the same way and had his prick driven deep into her tight pink anus stretching her tight butt making her moan with pleasure. Rob and I began to thrust hard and fast in the girls assholes as Pat and Peggy licked and fingered their hot tight pussies. The combined assault on their cunts and asshole had they climaxing over and over their pussy and asshole going into regular spasm around our cocks and our wives fingers. As we fucked their daughters butts Cathy and Bob were working Pat and Peggy's pussies and soon Bob's cock was stiff again. Pat was begging to be ass fucked so Cathy held her legs back while Bob moved in and stuffed his cock up Pat's tight asshole pumping her to climax quickly and filling her tight anus with an thick load of sperm as his wife Cathy licked and sucked Pat's stiff clit and fingered her open dripping slit. Bob's climax stirred Sue on and in a final climatic frenzy her asshole clamped my cock so hard she mad me cum and filled her tight young asshole with my steaming sperm. I fell back exhausted and watched as Pat licked up the sperm from Sue's battered open asshole as Sue licked her fathers load from Pat's spermy butt. Sue sucked her father's cock quickly brining him to erection. Bob and Cathy moved in on Peggy, Rob and Terri and spread Peggy's legs opening her hot cunt and tight asshole. Cathy quickly stuffed her fingers up Peggy's pussy and guided her husbands renewed erection up Peggy's asshole as Rob continued to Pump Terri's stretched asshole with long slow strokes. As Bob started to ream Peggy's asshole Terri came alive again having climaxed multiple times before her recovery was remarkable. Bob was thrusting deep and hard up my wife's asshole and she began to climax and thrust her hips as Bob filled her ass with sperm. Rob began to really pound his cock up Terri's battered butt and brought her to a final climax as he filled her tight butt with his steaming load. Everyone was exhausted and we layed around in the warm sun for a while before slipping into the pool for a refreshing dip.
I thanked Bob and Cathy for including us in their lust and invited them to join one of our parties soon. The told us they would love it and I held Terri to me and told her how much I loved fucking her hot young body. Terri kissed me and told me that she had never cum so many times and that she and her sister wanted to get together with us again. I had a brief moment with Sue where she echoed her sister Terri's sentiments and I promised we would get together again soon. Pat, Peggy, Rob and I had to leave but we managed to eat the girls, Cathy an Bob to one more climax before dressing and leaving them to rest and screw themselves the rest of the day.
On the way home Pat spoke up telling Rob that she thought her sister Betty and her husband Tom would be good candidates to include in our family fuck group. Peggy and I wonder where this all was going to lead but suggested we all work on the idea and see if we could recruit Betty and Tom next weekend.
Part 7
As I have explained in my previous stories my wife Peggy and I have undergone a real change in our sex lives because of our experiences with our inlaws. The first time was with my wife's sister Ruth and her husband and swinging friends. When we returned we were looking expand our circle of sexual friends and managed to first lure my brother Rob's wife Pat into a hot sex orgy with us. Then got Rob involved with my wife Peggy and his wife Pat making us all one big fucking family. My chance encounter with an old friend Cathy really highlighted our encounter and extended our sexual circle of friends to include Cathy her husband Bob and Bob's daughters from his first marriage who were living with Cathy and Bob. Our next goal was to seduce Pat's sister Betty and Betty's husband Tom into our carnal circle.
All week I kept thinking of how we could get Betty and Tom introduced to our fuck group and Peggy, Pat, Rob and I went over various schemes until we settled on one which we felt had promise. Our plan was fairly simple and it depended on seducing Tom first since Pat had told us that she and her sister had made it with each other when they were kids. Pat felt sure she could turn Betty on if Betty was sure her husband was already into swapping. I told Pat I felt that she would have no problem getting Tom involved as he was a plumbing contractor by trade and had already confide to me a few adventures he had at the homes of unsuspecting husbands while they were at work. Pat, Peggy and Rob agreed and we arranged for Tom to come over on friday to fix a problem with our bathroom sink. I planned to come home at noon and discover Peggy, Pat and Tom in the act and then join them. The week dragged by slowly and I was anxious for Friday to arrive so that we could spring our plan.
Finally it was friday and Peggy called me to let me know Tom had arrived and that I should start for home. My cock got hard just thinking of how Tom and I would be pleasuring my wife Peggy and my brother's wife Pat, and later her sister Betty.
Pat had come over to visit and she and Peggy planned to let Tom see them making it with each other then see if he would bite on the bait and join them. Rob couldn't get away until later that evening so I was to walk in on their fun and clinch the deal. Rob would swing by later and the five of us would party and set things up with Tom to bring his wife Betty by the next evening for dinner. Betty is a great looking blond with big tits and a great figure her pussy is now always shaved close and she loves both women and men taking cock up her ass at every opportunity. But before I get carried away let me turn the story over to Pat and let her tell you first hand how things went that hot Friday in July.
