The younger sister of my spouse, with whom I had always playfully cuddled and flirted, recently tied the knot with a British military man.

They had moved into their first new house, which they had purchased cheaply due to financial difficulties; the old detached house needed a lot of work, which I offered to assist with.

I was multi-skilled and knew lots of people in the trade who were keen to help, most of them fancying their chances with my sister-in-law, Laura.

At the time, Laura was only twenty-four. Her legs would have made any model jealous, and she had big blue eyes, kissable red pouty lips, and long, curly red hair.

She was a lady's size ten with a notable pair of breasts that were at least a C-cup in size. Her build was proportionate—not skinny but not fat.

Laura's dress code consisted of wearing low-cut tops to accentuate her cleavage, short skirts, and high heels to flaunt her perfectly long legs and adorable peach of an arse, and very rarely a bra because she was firm and natural.

Laura's husband was sent on a six-month secondment overseas soon after the wedding, leaving her home alone and in need of a lot of assistance to get the place ready for Martin's return.

My wife and I spent every spare minute helping mend, repair, and redecorate, mostly at our expense. I was there most evenings with one or more of my buddies to complete the work required before Martins returned.

We all grew accustomed to seeing Laura walking around in the barest of clothes, either en route to or from her workouts at the Bailey gym, and it was not out of the ordinary to see her dressed in nothing more than a towel right out of the shower.

All of us had a deep-seated desire to see her nude, and as the days passed, our goal seemed ever closer.

Although he was the one who received the most praise from Laura—primarily because it was his responsibility to replace and update the bathroom and shower—one of my plumber friends, Barry, a man in his early sixties, spent a lot of time chatting with Laura and never seemed to get things done.

After he finished the bathroom, the kitchen appeared to be a place where she spent a lot of time. He laid the foundation, we installed the units, and he completed the plumbing and added the final details. Given the praise he received, you would think he completed all the work by himself.

The day after Barry finished all of the plumbing, I went back to Laura's house to finish off some projects I had been working on. It had been a long day at work, and I did not think anyone else would be at the house.

I assumed Laura was at the gym when I let myself in as usual and was unable to see her. That is, until I heard Barry's voice from the upper level. Strange, I thought, so I scampered upstairs and peeked around the bathroom door. Steam was pouring out onto the landing, and I could hear moaning and running water.

When I looked in, I saw Laura naked on her knees, Barry nude beneath the showerhead, water dripping over him, and Barry's cock in her mouth. With my phone in my hand, I turned on the video recorder and captured Laura giving Barry a great blowjob on camera.

Barry was fucking Laura's mouth while she was giving his short, fat cock a hard time and petting his balls. She slowly slid her lips down his length, and he had his hands on the back of her head.

He was groaning, and it would not be long before he filled her mouth. While I was trying to get a better look, the door creaked. Barry glanced at me while I was squeezing my cock with one hand and holding my phone with the other. He heard the door and simply grinned and gave me the thumbs up while shoving his balls down her throat.

Laura swallowed, then removed her mouth from his member to kiss the very tip of his dwindling penis. She raised her head to see Barry staring at me. She turned to face me, and as she attempted to hide her nudity, her entire body blushed with humiliation. "Oh sh*t, please do not tell anyone what you just saw," she exclaimed. "Oh sh*t, you did record it?"

"Yep, for the same treatment you secret, it is safe," I replied.

Barry emerged from the shower, dried off, and put on some clothes while maintaining his Cheshire cat smile. Laura pulled out the biggest towel and wrapped it around her, sobbing as she sat on the toilet seat.

"Barry, it is time for you to go; you have had enough fun," I said.

Barry gave a nod, gathered his belongings, thanked Laura, and walked out. He said, "Please forward me a copy," as he walked away.

"Lounge, now!" I said to Laura. "We must speak."

Laura was more upset about being discovered than about what she had done—it was obvious that she had enjoyed every moment and had made an elderly man very happy.

Laura admitted that it was not the first time she had slept with Barry; in fact, they had been enjoying each other's company for more than a week.

I replied, "You could have come to me; I would be happy to help if all you needed was sex." Barry is almost twenty years older than your father. Why did you do that?"

Laura said she was tempted to. "I knew you had a big cock, Jo told me, and I really wanted Barry to be you, but he was there, willing, and he has a fat cock, and I thought you would think I was being stupid and you would not want me."

I did not mean to imply that you had to fuck me in order to keep your secret; mine is much bigger and fatter. I mentioned.

"I want you, but it is not just a wham bam job; it has to be nice. The timing has to be right," Laura remarked.

Laura gave me a bear hug while her tears were still streaming down her cheeks. When she released me from our embrace, her towel fell to the floor, allowing me to get a close-up look at her flawless figure. She appeared unhappy and ashamed.

Laura did not even try to hide; she just grinned and stooped to pick up her towel and wrap it around her once more.

"What are you going to do with the video?" asked Laura. Would you please give me a copy?"

"I am not sure, but I am sure Jo would love to see it; then we will decide," I uttered.

I completed the task I had come to do, shot Laura a cold look, and left for home.

Laura begged me not to show Martin or Jo as I was leaving.

I had a shower at home. After the sex show, I was horny and wanted to show Jo the tape.

"I have something you need to see; please do not say anything until the very end, and do not pass judgement on anyone in it. We will talk about it at the end," I said to Jo.

Jo concurred.

I changed the recording to the large-screen TV and then pressed the play button. There was more steam than I realised, but as soon as I opened the door, it cleared, making the action easy to see. Still, my hand was trembling.

"Why is it shaking so much?" Jo asked.

"I was wanking my cock with my other hand," I uttered.

"Her response was, Eww, why?" she cried out.

I said, "Just shut up and watch it."

Jo let out a gasp, turned to face me, and then looked back at the screen, her hand going to her mouth as the scene played out.

She merely remarked, "Barry has a nice cock for his age," at the end, looking shocked.

"So, what are we going to do about this?" I asked.

I recounted the events and mentioned that Laura had been seeing Barry for a week because she was so desperate for sex after Martin's extended absence. I acknowledged that I had offered Laura my services, which she had turned down thus far.

Jo devised a scheme that would make everyone pleased. She made the decision to do some partner swapping and invited Laura and Barry over for dinner. Jo could try out Barry's fat cock, and I could help Laura out by making her feel good.

Upon my subsequent visit, I showed Laura the video and successfully played it on her bedroom's wide-screen TV—the only functional TV she owned. While it played, we sat on the edge of the bed. Despite her desire to watch it repeatedly, Laura winced at the sight of it. When she finally saw me with an erection in my jeans, she put her hand over it and stroked me while it played out.

"It is big; I look forward to seeing it in the flesh," she remarked afterward.

"You know you can see it anytime you want; we are family, and we have no secrets," I joked in response.

"All right," she replied. "I want to see it now; drop your jeans."

I simply laughed and got up, getting ready to head home. Laura took hold of my arm and gave me a look. "I want to see it now; I am not kidding," she stated.

She was still sitting on the edge of her bed when I got up to face her. "Really?" I asked her, putting my hands on my belt as I looked at her. said I.

"Yes, go ahead and do it."

Although I usually have no trouble showing people, this was my stunning sister-in-law.

She urged, "Come on, what are you waiting for?"

I removed my belt, undid the stud, and lowered my zip. Since I do not usually wear boxers, she was now staring at my shaved pubic area. I asked, "Are you sure?" with my bulge being enormous and my jeans fitting too tight.

She licked her lips and nodded. With her face just a foot away from my crotch, I felt both anxious and eager.

I pulled my jeans down to my knees quickly, and my nine-inch cock shot out of them, almost hitting her in the face. He was standing proudly, fat-shaven, and circumcised.

I had no control over Laura's hands reaching out to grab hold of me. She was staring at my pole in disbelief, both hands wrapped around it. "Jo did not tell me you were circumcised, but I knew it was big!" "This is huge!"

As pre-cum oozed out of the end, she was slowly pumping my cock with one hand and exploring every inch with the other. Laura used her fingers to remove the pre-cum, then she placed them in her mouth, sucked them dry, and moaned a little. She said, "Mmm, you are salty."

Since I first met Laura, I had been dreaming of this moment, so when it finally came true, I was at a loss for what to do.

Laura was looking up at me as I edged closer to her, closing the gap to only a few inches. I had the perfect view of her cleavage from above and could see her erect nipples through her crop top.

"All right, this ends now; the time is not right; I have to leave," I said.

I did not mean to say it, but I had to, so Laura opened her tiny mouth and moved it towards my cock, kissing the tip and swirling her tongue around the end along my circumcision scar—all of which were driving me crazy.

Her lips moved only a few inches down my length, her mouth tight around my pole, but it felt good and right. At that moment, I was in a dreamlike state. With about three inches in her mouth, she stopped, looked up, winked, and then slowly moved her lips up and down, one hand caressing my balls and the other giving me a powerful pump—a clear attempt to get me to cough quickly.

Her mouth action increased to that of her hand. I tried to grab her breasts but was pushed away as she brought me to one of the fastest eruptions I had had since my teens. I gripped the back of her head as I fired my first load, but she shook me off and continued to move her mouth up and down my pole while her hands pumped and caressed me.

When she realised that she had completely sucked me dry, she stopped, kissed my cock from tip to ball, sucked each ball separately, got up, and kissed me full mouth while sharing my salty semen.

"We have lots of time left before Martin gets home, so that was in appreciation for being such a gentleman and always being there for me." She said, whispering.

It was not like Laura had any expectations of me, so I dressed accordingly. After she watched the recording, I told her about Jo's invitation and that she was excited to service Barry's old cock and for us to have fun. Jo proposed inviting her friends Amy and Jake, who were enthusiastic about having fun despite being only 19 years old. Jo' was equally enamoured with Jake's curving manhood.

"Jake would like you; I am sure he would love to have some fun with you. Jo loves it and has had it many times. He has a seven-inch, curved-thick cock that you would love."

She cried out, "Jo has other cocks when she has the pleasure of your monster, why?"

"I guess we are sort of swingers," I said.

I could get three different cocks in one night, mmm, that sounds exciting.

Taking out my phone, I played a video of Jo giving Jake a blowjob. She was taken aback but delighted to see the size and shape of his seven-inch cock.

"Martin should never find out; it is going to be an amazing night." She licked her lips and said,.

Jo noticed the expression on my face and assumed I had been up to no good. "Laura gave you a blowjob tonight, did not she?" she asked when I got home.

"How did you find out that she did?" I stated.

"She told me what she did and admitted she loved your big cock over the phone, all excited about Jake," Jo said.

When Jo contacted Amy about the party, she was excited but unsure about Barry until she sent him the video of Laura blowing him, at which point she decided she wanted Barry too.

Jake was not given a voice, but I knew he would be thrilled to have three attractive women want his cock and that he would not refuse them.

We set a date, and Jo got to work organising our schedule so that we could eventually get around to having sex with each other.

The party will be described in the next part once it has happened.
