My wife and I have been married for five years and have enjoyed a long, monogamous relationship. I never claimed to be really experienced at sex prior to our marriage, and my wife went to the altar a virgin. However, we learned quickly and developed a very satisfying sex life. In fact, both of us like to have sex almost every day. If we can’t for some reason, we both get kind of cranky and obsessed until our urges are satisfied.

This has made us very compatible over the years. Tracy is a petite brunette with an ass that turns heads (mine at least). At 5’ 1” and 102 lbs., she has oversized breasts that capture one’s attention. I thank heaven that she picked me to be her life partner.

About six months ago, I received a call from an old “buddy” saying he was going to be in town for a couple of weeks and would like to get together with me and my wife.

Steve and I had been really close before he stole my girlfriend from me our senior year. We had not talked since graduation. He went off to college and became an architect, while I got a job at the mill. The only reason I eventually forgave him is because I figured he had done me a favor. The girl I had been dating turned out to be a total slut. She hadn’t put out for me but had developed quite a reputation after Steve had finished dating her. A short time later, I met Tracy, and my life has been wonderful ever since.

Anyway, Steve offered to buy us dinner at a nice restaurant while he was in town. During dinner, Steve mentioned he would be staying at a hotel out of town because a convention had booked all the local rooms. Well, Tracy would have none of that and kindly offered the use of our extra bedroom for the duration of his stay.

Steve quickly accepted.

We hardly saw Steve the first couple of days he stayed at our home because of his work schedule. However, Thursday evening Tracy accidentally walked in on him while he was getting out of the shower. She ran back into our bedroom gasping with a look of shock on her face.

I asked her what had happened and she explained that she had seen Steve naked. I told her it was no big deal and that he’d get over it.

She said that it was indeed a big deal, an eight-inch ‘big deal’ and he hadn’t even been hard.

I laughed about it a little nervously, but didn’t think much more of the incident until later that night. My wife and I were getting sexy and she was slowly stroking my 5 inches when she mentioned the size of Steve’s cock again. She wondered out loud how big it was hard.

I told her that I would ask him if she wanted to really know, thinking to shock her out of this silliness. She giggled and seemed to forget the whole thing and we had some great sex that night.

The next day I thought “what the heck” and told Steve about the incident. He laughed and said that for Tracy’s information he was 12” long when he was hard. I looked at him in amazement, then shrugged thinking of my own size. I couldn’t believe that I had penis envy. Steve must have read my thoughts because he asked me about the size of mine. When I told him honestly that I was 5”, when hard. I had never really thought about size before, but when leaned close and said he knew how I felt. I gave him my “yeah, right” sarcastic look.

He lowered his voice and asked if I could keep a secret. I nodded then he said that a couple of years ago his penis was even smaller than mine. I looked at him in further disbelief. He looked me straight in the eyes and said “It’s true, I found a way to permanently increase the size of my cock!” My expression didn’t change. “I’ll bet it could work for you too if you wanted! It’s really pretty simple and doesn’t hurt a bit!” he added in response to my skepticism.

I had to admit that I was intrigued by the thought. I could just imagine skewering my lovely wife deep and hard with my king-sized cock. That would shut her up, I thought.

Steve could somehow tell that I was interested but wary. He put his hand to his chin like he was deep in thought, formulating an idea. Then he raised his eyebrows as if he had just come up with some sort of idea.

“What?” I asked.

Steve insisted that I let him help me out, that he’d walk me through the whole process, and that he even had the equipment for me to use. He said that he wanted the satisfaction of helping out an old friend, and perhaps make up for taking my girlfriend all those years ago. “Besides,” he continued, “Tracy needs to experience the thrill of a full-size cock. Women who do are never satisfied with ‘little’ again.”

Later that night, I discussed our talk with Tracy. I asked her what she thought of Steve’s offer. Would she prefer me with a large cock? She was silent for a while. Finally, she sighed and said, “Well, if there is nothing to lose, then what the heck?”

I suspect that she was more excited than she let on because the sex that night was some of our best ever.

After we came down, she asked what the procedure was for the “enlargement”. I told her that Steve had not yet filled me in on all the details, but we would find out tomorrow.

I woke up in the middle of the night to find Tracy next to me in bed and rubbing her pussy. I pretended to just roll over so she wouldn’t notice that I was awake. The thought of being fucked by a large dick had obviously had its effect on her.

The next afternoon, Steve called me into his room. He reached into a bag and pulled out what appeared to be an oversized transparent bicycle pump. “This is it!” he proudly proclaimed.

I must have had a confused look on my face because he smiled and said, “Trust me.” He went on to explain the general procedure. I was to use this device 3 to 4 times a day to “invigorate” my member. He said it involved sticking my cock into the end of the tube and pumping on the handle. During the use of the tube, my cock would greatly expand in size until I came. After orgasm, my cock would return to its normal size.

This all would happen during the “development” phase of the process. The development phase could last from a couple of weeks to many months if I slacked off on the invigoration. However, eventually, the change would come.

When my cock had become acclimated to the increased size, it would simply not get smaller after an invigoration-induced orgasm. Presto, huge cock! He said the best part was that the invigoration phase was fun. Tracy could even help out! He even estimated that based on the size of my cock right now, I could anticipate at least 14” when finished. I would dwarf his own large member.

He also said that it was important to “set” the final size once achieved, otherwise, it might not “take” properly.

According to him, setting the size requires a constant external pressure on the penis just after the final size is attained. This pressure somehow negates the vacuum effect that the tube causes, thus setting the size. Fortunately, an accommodating pussy does just the trick. I didn’t really understand what he was talking about. I was never all that great in science.

But Steve assured me that we could worry about that later. Besides, he said, “Tracy will love it!” Well, that was all it took to get me started. I took the tube and headed to the bathroom. My first attempt was a little clumsy, but I soon got the hang of it. My cock really did look bigger in the tube. The orgasm shook my body. I thought the treatment might end up being more fun than I anticipated. Later that day, I invigorated twice more until my cock was limp.

When Tracy came home, I told her all about it. She got so charged up that she jumped me on the spot. It was then that I realized the main side effect. The invigoration process left my cock too sore and tired to be of any use to Tracy. I rubbed her off, but it just wasn’t the same. She really needed that to satisfy her needs. We both agreed the payoff would be worth it.

After about a week, Steve prepared to leave for home, saying he would be back in town in a couple of weeks. He instructed me to keep with it and encouraged Tracy to think of large cocks in her dreams. He knew it was only a matter of time before her dream would be a reality.

As it turned out, Steve didn’t get back into town for about three weeks. Again, he stayed in our spare room. Tracy seemed especially glad to see him. I wanted to ask him if he thought treatment was working on me and when I could expect some results.

It was getting tiring using the tube three times a day.

My cock was like a limp rag doll between sessions, and Tracy was starting to get really cranky.

After he was done unpacking, I asked Steve for an assessment of my progress. Even though I was really embarrassed to do it, I showed him my erect penis to get his opinion on whether or not I had grown.

He said he wasn’t sure, but everything appeared to be on track. It could happen any day now.

Tracy and I were thrilled. All that effort was going to pay off, I was positive.

Steve cautioned us that although it “appeared good”, the final enlargement might still be some time away. There was no real way to predict the exact time. He then asked me if I had thought any more about preparing to “set” the final size.

I told him that I didn’t really understand the question. He reminded me that it was very important to complete the procedure, otherwise, all the effort could be lost. I must have looked puzzled. Steve took a deep breath and said, “Remember, the best and easiest way to achieve the proper pressure is to fuck an accommodating pussy.”

I did vaguely recall him mentioning that. I asked what the problem was. Tracy had been waiting for this moment for 4 weeks.

Steve shook his head and repeated, “Accommodating! Do you think Tracy will be able to handle all 14” of your dick when she has been used to your original 5 inches?”
