Recap: Ken and June were at June’s brother’s place for dinner, drinks, and card games but ended up having sex with her brother and his wife to try and get her pregnant.

As we sat around still naked, we started to plan; they lived not too far from us, so we figured we could put this plan into action relatively quickly.  Once I had Leo, Heather, and June on board with the plan, we would have to seduce Leo and June's parents (Mike and Lisa). June and Heather each agreed that they wanted to have a go with Mike before he planted his seed in Heather. While he fucked them both Leo and I would have our way with Lisa.

Though Mike and Lisa were older, they still looked and acted like a young couple. Having had three kids (June, Leo, and their brother Pete) at a young age, they did their best to stay active. Mike, who had an average build in his mid-fifties, kept fit and still had jet-black hair and youthful vigor, competing regularly in marathons.

Lisa was still quite a looker in some books. She had that mom look from the 90s with her shoulder-length black hair but had started to embrace the grey hair that peppered her hair now. She and June were very close in body type and height the only real difference was that Lisa’s boobs were just a smidge bigger from having three kids.

I, however, knew something no one else did: Mike and I both had vasectomies. So I found this out a few months back. June and I were at a swingers' party a few towns over. June and I had just finished partying with one of our couple friends. The girls were going to get cleaned up when I was walking past a room and heard a familiar voice.

A general rule for this event was to close the door if you have a room and want to be left alone; if you don't mind a crowd, leave the door open. As a voyeur, I saw this as an opportunity to see maybe someone I knew.

As I entered the room there were a few people against the wall making out but paying attention to the people fucking on the bed in the center of the room. They were facing away from the door, going doggie-style, so I walked to the side to see the action going on. 

I walked to the opposite side of the room from the couples making out, and as I saw the people putting on the show, I was a little shocked. There was my mother-in-law Lisa getting fucked by some dude. I looked at the couple against the wall and it was my father-in-law Mike and some chick. 

They were each paired with a younger partner, Mike was kissing the nap of the female while she stroked his erection. They would look at the show in front of them occasionally, not paying much attention to anyone else in the room.

“Hey new guy price for the show is a blowjob,” Lisa said between her breaths. She hadn't looked up to see my face yet, so I hesitantly walked over and positioned myself in front of her.

Once in place, she was lightning quick and sucked my dick into her mouth, and that is when I felt it. This dude behind her wasn't hammering her, she was ramming herself onto him.

She was going to town on my cock, pulling it out occasionally to lick it and run her mouth up and down the side of my shaft. Then taking it down her throat until he nose was planted into my pubes.

It wasn't until about the fourth or fifth time she took my dick out of her mouth that she looked up at me. I could tell in her eyes that waves of shock, surprise, and excitement were running through her.

“I bet you're enjoying this little show, aren't you?” Lisa said, smirking up at me before diving her lips back onto my cock. I took that as a queue and placed my hands on her head to assist with this blowjob. 

She kept bobbing up and down and twisting her tongue around my shaft for the next few minutes until I felt her body change pace. She lost control and her body shook as her orgasm crashed through her body. 

I looked across to the guy behind her as he fell back, obviously having just cum as well. She released my dick from her mouth and fell onto the bed. I looked over at Mike. We made eye contact for the first time, and he just winked at me before planting one last kiss on his partner. Then, she approached her guy as he stumbled out of bed. 

As the unnamed couple said their goodbyes and left the room it was now just me and my in-laws. Mike looked at me and asked if June knew I was there. 

“Here, in general, she is with one of our friends a few rooms down. Does she know you two are here?” I said. 

“We should talk later about this, and trust me, there will be consequences, but don't worry. I think we can all find a way of coexisting moving forward, but we have to be willing to work together,” Lisa said.

Mike and Lisa picked up some clothes from the corner of the room and started to get dressed. We arranged to meet up for coffee in two days so we could all talk, minus June, who they weren't comfortable being seen by yet.

TWO DAYS LATER

I was in the living room on the couch of Mike and Lisa’s place silently sitting opposite of them as we all kind of looked around at each other. I finally broke the silence asking how long they had been members of the club.

They started telling me their story of how they had always been sexually active before and after having the kids. How after Pete had moved out for college they seemed to keep wanting to push their experiences more and more.

They had looked online and found various member sites and groups they had joined and met up with every so often. Lisa admitted they were quite popular in their circle since they were both sterile, Lisa having her tubes tied and Mike having a vasectomy several years back. 

Mike added it was also because he could still cum bucket loads for the girls that wanted to be covered in sperm, and Lisa had an insatiable appetite and could fuck for hours going from partner to partner sometimes.

Just then, the phone rang; Mike answered it, stepping away. Lisa and I talked for a few minutes about some of the members that they had met and explained the couple they were with the other night were brother and sister. I was a little shocked but she went on saying they were fantasizing that they were their parents.

Mike came back into the living room and excused himself; he had to go into his office and help with an issue quickly, and then he would be right back.

He left kissing Lisa and giving me a pat on the shoulder.

Lisa went on to say that she and Mike did delve into incest from time to time as they didn't see it as a big deal with lovemaking. She went on to tell me about her first experience with her older brother Ben. 

They had been close in age growing up and, during college, attended a few parties separately and ended up sleeping together a few times. Once she and Mike started dating, she knew she wanted to be with him forever, so she stepped back from fucking her brother.

It was only a few years after they had been married and were starting their push into their kinky lifestyles that she admitted to Mike about sleeping with her brother. It was then that Mike told her that he had a similar experience with one of his older sisters and her daughter who was his age.

I was excited by her telling me all these stories, and looking at her, she was too. She had been wearing a tight white button-up blouse and a short jean skirt that she was rubbing her legs together as she talked, as well as her nipples becoming more prominent through the blouse as she went on.

Lisa started talking about a time when she had a threesome with Mike and her brother Ben.

As she described being between the two of them, she ran her hands over her breasts, and one hand moved towards the buttons of her blouse. She slowly started to pop them off one by one, revealing her breasts to me while playing with her nipples. 

She had stopped telling her story as she was now pulling at her nipples; slowly, she moved one hand down to the waistband of her skirt. Popping the button and diving her hand down to play with her pussy. 

Keeping eye contact with me, she stood up, pushing her skirt to the floor, revealing that she was not wearing any underwear, and leaving her shirt open, moving towards my position on the other couch.

She knelt in front of me sliding her hands from my knees up my thighs to my waist. Gripping my cock over my pants as she moved one hand to my belt to start unfastening it.

“I’ve been thinking about this cock since I found out it belonged to you,” she said, looking up at me. “I feel kind of bad that you didn't cum for me while I had you in my mouth,” she continued as she pulled my growing erection free from its cloth prison.

“Well I had been fucking your daughter and one of her friends quite a bit that night,” I said.

With the mention of June, a flair of lust burst into Lisa’s eyes and she dove onto my cock with the same passion she had the previous night. 

Her tongue moved with such passion over my cock, it was mere moments before every inch of it was glistening with a mix of her saliva and my precum. She was bobbling her head up and down several times. Then, to relax her jaws, she would pop my dick out and then lick from the tip of my cock down to my balls.

I was getting close to cumming from these intense actions, however, she didn't want this to end just yet.

I had already removed my shirt and pants during her assault on my cock; when she came up for air, I grabbed her by her armpits and pulled her up. We kissed for the first time not as son in law, mother in law but as lovers. Our lips parted, and our tongues played together, exploring each other. After what seemed like only a few seconds I pushed her away and up, so she was not standing on the couch above me. 

She lined my face up with her pussy and I dove into her neatly trimmed mound. My tongue made easy work of parting her lips and finding her swollen clit. I did my best to lap her juices as they flowed from her.

My head planted firmly between her legs, she clenched a handful of hair from my head and ground her pussy into my face.  I drank up her juices as they streamed down into my mouth, and I could feel the runoff hitting my chest. 

Her movement became more forceful as I continued to play with her clit. I felt her orgasm start to build as she held my face deeper into her pussy. As she cried out I kept my tongue planted as deep as I could get it lapping inside her love tunnel.

Releasing my head she slid down into my lap, her pussy lips resting on either side of my dick. Her mouth found mine and we embraced into a kiss as our tongues explored each other's mouths. 

With her arms around my neck, she started to grind her pussy over my cock, lubing it up for her next assault. My cock was aching at this point, she had been teasing me for too long at this point. Fortunately, she realized this and lifted herself a bit to line up her pussy and my cock. 

She playfully bit my lip as she slammed herself down onto my cock. I felt the wetness and heat as she slid up and down onto my cock. She started to bounce up and down my shaft, and while she did so she pushed my head into her tits. 

I took this time to play with her nipples, I licked and nibbled on them swirling them with my tongue. 

After a few minutes, I wrapped my arms around her and rolled her onto the couch. I enjoyed the sight of her breasts as they wobbled from my pounding into her. She gripped around my neck pulling me into a kiss, at the same time she hooked her legs behind me as I speed up my pounding. 

It wasn't long until I felt her pussy tighten around my cock, her nails digging into my back as she orgasmed again. 

As she screamed out her ecstasy I felt my orgasm building up and switched to shorter thrusts.

“Cum.. on my… tits,” Lisa said 

So quickly I pulled out and she got onto her knees, presenting her tits to me while sticking her tongue out. 

That was the final push as I spurted first onto her face, then the remaining spurts onto her tits leaving quite a mess for her. 

She cleaned up the mess stood up and kissed me again.

“That was amazing. Mike and I are going to enjoy you some more in the future," Lisa said.

We cleaned up and I had to head home, but we decided to meet up every so often for repeat experiences. As we did Mike joined a few times watching me fuck his wife, but most of the time he would join in, Lisa sandwiched between us. 

It was one of those times that they talked to me about wanting to watch me and June together and maybe even join us. I told them that we might be able to work on something in time.

It was with that knowledge that back today, I sat around with my brother-in-law and sister-in-law. That we were going to have an orgy with June's family. Granted, it wouldn't result in pregnancy like Heather wanted, but I had another plan forming at this point as well. 

No one remembered their younger brother Pete.
