I had read many stories about young married men whose once innocent wives ended up being a slut to a well-hung stud. I thought that they were just stories people made up. It could never happen to me, could it?
Like all teenage boys, I was a little self-conscious about my body and my penis in particular. In my late teens and early twenties, I had a few lovers, mostly one-night stands, the odd month- or two-month relationship along the way. I never had any complaints about my performance, but then again, I didn’t normally stick around that long to get any feedback.
At the age of 23, I met my wife, Rachel. She was 20 at the time and one of a dying breed, a ‘traditional girl.’ From day one, it was made clear to me that I would not be getting into her panties unless I married her. You know the next part of the story before I even write it. I fell big time for the young girl, and within a year, I was a married man.
Rachel was, can best describe as, a classic girl next door beauty. She was around 5.3 in height and around 100 pounds. She had dark, wavy hair and an innocent yet beautiful face. Her breasts are small but very firm, and when she gets excited, her nipples get very pointy.
Sex between us was very good. She had a great body, and being a virgin, she has a very tight pussy that seemed to fit me like a glove. We had what I thought was a healthy sex life. We did it 3/4 times a week and even tried a few different positions. Rachel wasn’t all that into oral, but she gave it a go for a few minutes but never swallowed. She seemed very content with our sex life and thought that I had a large, thick penis.
From our discussion, I knew that she had never seen another man’s penis except for mine. When hard, I guess my cock is around 5.5, maybe 6 inches, and pretty thick. When relaxed, it is normally around 2 inches.
So I was happy that my young wife thought I was big, even though I knew that I was just an average-sized guy. I remember the incident when my bubble began to burst. We were watching a documentary about nudists when the camera zoomed in on this naked old guy who was walking along the beach. “Wow, his penis is huge!” my wife said.
I found it pretty funny at the time because the guy was old and fat, and his cock was only hanging down about 3 1/2 inches. I didn’t give the incident that much more thought until a few days later. After sex, my wife seemed to be examining my cock. “How big is your penis, dear?” she asked me.
I told her it was about 6 inches, and I thought that would be the end of the matter, but she went on. “Is that big or just average?” She asked. I guess it’s average, I replied. She asked me how much bigger than mine they got, so I told her that some could be as big as 9 or even 10 inches, but that was very rare. I added that I thought most guys were between 5 and 7 inches, but that it was not so uncommon for a guy to have an 8-inch cock.
To my surprise, she took a ruler from her desk and looked at the 8-inch mark and ran her finger along it and said that she didn’t believe me. “A penis cannot be that big,” she said.
We live in an apartment building in New Jersey, and next door lives a much older couple, a married couple named Stan and Elaine. Stan and I had gotten quite friendly over the next year or two, and being a young guy, I often confided in him about my personal life.
Stan was probably around 58 or 59, and his wife not that much older than him. I spoke to Stan a lot about sex. He told me that he and Elaine didn’t do it very often anymore as she had lost interest. He also told me that I was a lucky guy having such a lovely young wife and that I should enjoy my sex life whilst she was still interested. I even told him about her size questions, and he laughed, saying it was just natural curiosity on her part. Stan asked me my size, and I told him that I was about 6 inches. He gave me a strange smile and said he was also 6 inches.
Every summer, Elaine goes to her mother’s in Florida for 2 weeks, and Stan stays at home because he has to work. He confided in me once that he could get the time off, but he prefers to stay at home rather than spend 2 weeks with his wife’s mother.
One Sunday when his wife was away, he invited us over for drinks and lunch. We had a nice lunch and probably two or three drinks each. It doesn’t take a lot for my wife to get drunk, and after her 3rd drink, she was getting very relaxed. “I just got our new hot tub installed,” Stan informed us. It was actually my wife’s idea that we all try it out.
We all agreed that it would be fun. Stan joked that a hot tub was best when everyone was nude. My wife laughed and said that us men could be silly and go nude but that she was keeping her clothes on. “Oh, but I don’t have a bikini,” Rachel said. She had thrown away her old one when she had moved into our apartment two years ago when we got married and had never gotten around to buying one.
“Just wear your underwear, Rachel. It’s more or less the same as a bikini anyway,” Stan said. “I don’t know. It doesn’t seem right,” she replied. “I tell you what. Why don’t Jon (that’s my name, by the way) and I go in our underwear so that you don’t feel weird?” Stan suggested. She agreed, and we all stripped down to our underwear.
I was a bit embarrassed as I was wearing tidy whities and Stan was wearing boxers. I was very surprised that my conservative wife had agreed to go into the hot tub in her underwear, especially when I found out that she was wearing a very sexy matching black silky set, but I guess that the alcohol had a big part in her losing some of her inhibitions.
We continued to drink whilst we were in the tub, and the conversation became more and more sexual. Stan seemed to be flirting a bit with my wife, but I didn’t mind as I didn’t see him as any threat, as he was just the old man next door. He had commented a few times how sexy my wife looked in her underwear and how I was a lucky man.
Rachel seemed to enjoy the ‘harmless’ flirting. Everyone was very relaxed at this point, and Stan continued the sexual conversation, telling us of his conquests as a younger man. He had also said on more than one occasion how he would much prefer to be naked in the tub as it was much more relaxing. Rachel eventually commented jokingly that as it was his tub, he could do whatever he wanted.
“Would you really not mind if I took my boxers, Rachel?” he asked. “It’s your house, Stan,” she replied. “How about you, Jon? Would you mind if I got naked in front of your wife?” he asked me. Now I was starting to think that he was actually serious, and I remembered my wife’s curiosity.
I told him to go ahead, safe in the knowledge that even if he was not joking, he had already told me that his cock was also just 6 inches. Stan then took off his underwear and threw them across the room. My wife and I laughed along with Stan. “This is so much better,” Stan told us. “Why don’t you take off yours too, Jon?” I said, “What the heck?” and threw mine across the room too.
About half an hour later, Stan walked out of the tub and, to my wife’s and my amusement, walked with his naked backside to us across the room to get some towels. He came back with the towel across his waist, standing by the side of the tub. I went across as if I was going to get a towel, but instead, I jokingly tugged on Stan’s towel.
Now, I didn’t tug very hard, and I expected him to hold the towel up, but instead, Stan just let it drop to the floor and made no attempt to pick it back up again. I laughed for a few seconds until I looked at his naked body. Stan was standing naked by the side of the pool with his arms across his chest, with a small grin. When I caught sight of his groin, I nearly fainted. Hanging from our naked, nearly 60-year-old neighbor’s body was the largest penis I could ever imagine. It hung down like a giant sausage and was thick like a cucumber. I realized now that Stan had meant he was 6 inches soft, and not 6 inches hard like I had thought he had meant.
I turned around to see my wife staring at Stan’s crotch. “What are you two staring at? Haven’t you ever seen a penis before?” Stan said, breaking the silence. I didn’t say anything; my wife mumbled something about its size. Stan went on to say that we should both get out of the tub and that we could go and relax in the living room.
Rachel got out of the water first, and a still-naked Stan passed her a towel. Stan was talking to my wife at this point, and I could tell that she was struggling to look at his face and not his cock because she kept stealing glances at it every few seconds. I asked Stan for a towel, and instead of giving it to me, he told me to come and get it. I got out of the tub naked, trying tall, but I was very aware that my cock was very shriveled up at this point. Stan looked at my cock and smirked and passed me the towel, saying, “Here you go, boy.”
Stan finally covered himself up and went to change. My wife and I didn’t speak as we dried ourselves with our towels. Our clothes were in our own apartment where we had changed. Stan came back wearing a robe, and he passed my wife and me bathrobes too. He suggested that we change into our robes and stick around and continue the party.
I suggested to my wife that we get to take a nap or at least change into some clothes. I was feeling kind of insecure about myself now and didn’t feel like being naked except for a robe in Stan’s apartment.
To my surprise, my wife said that the robe would be fine for her. Not wanting to be a prude, I agreed, and Stan left the room for us to get changed. I noticed that when my wife stripped, her nipples were very erect as she gets when she’s excited. It could have been my imagination, but Rachel seemed to almost frown at my shrunken cock when I removed the towel from my waist.
Stan came back, and we all sat down in his lounge area. He went to prepare some more drinks. My wife looked very sexy in her cream satin robe, and I noticed her erect nipples through the fabric. I was still feeling very on edge at this point, and if it had been just my choice, I would have gone home. Rachel, however, seemed to be enjoying herself, and I didn’t want to ruin her fun.
Stan came back with the drinks and sat across from my wife and me. I could not help but steal glances at his groin every few minutes. I was still in shock at how big his cock was. Stan was again talking about his past sex life, telling us about all his past conquests. He also told us that he had never cheated on his wife, Elaine, in all their 28 years of marriage. He went on to say that he found it harder and harder to stay faithful of late because Elaine never wanted to have sex anymore. He told us that he was as horny as ever.
My wife normally does not like to talk with other people about sex, but today she was hanging on Stan’s every word. To my even bigger surprise, she started telling Stan that I had been her one and only and how she never saw the big deal about sex. I found this statement very shocking, especially as I was in the room. I guess that Rachel, being as naive as she was, didn’t see this as being something that might hint that my sexual performance was not up to par.
