Lou and I have been happily married for 35 years. (I’m 57 and he’s 61.)

We live in an eight-unit condo that keeps residents in close contact, which has its good points and not-so-good points.

Take our next-door neighbors, Stef and Rick, a 40-something interracial couple (she’s white and he’s black), plus Rick’s 20-year-old son from a previous marriage, Mack. We always got on fine. Then one Saturday afternoon a month and a half ago, when I was home by myself, the doorbell sounded and through the peephole I saw the young man, Mack, holding two cans of beer.

I let him in and invited him to have a seat on the sofa. I have to explain that Mack is simply gorgeous, with the body of a god, all beautiful rippling muscle. I admit that I had always loved just looking at him. He gave me a beer and we shot the bull for ten minutes or so, until he said, “Say, Gin, have you ever fooled around?”

I was startled, and didn’t answer right away, hoping he didn’t say what he just said — or maybe hoping he did. I just stared at him until he said, “So, have you ever cheated on Lou?” I quickly said no, but he said, “Have you ever wanted to?”

I told him that in 35 years of being married I’m sure the thought had entered my mind at times, but I don’t know why I said it — it was none of his business! He said, “If you had a chance, would you cheat on Lou?”

“I think you better go,” I said. “You’re a lovely boy, a beautiful boy, but your questions are making me uneasy.”

“I know you like to look at me,” he said. “It’s okay. I like the way you look at me. I’ve always liked looking at you. Tell me, have you ever seen a black man’s dick?”

I quickly said no.

“You want to see mine?”

“Mack, sweetheart, I think you better leave,” I said.

“Sweetheart?” he taunted as he headed toward the door. I was relieved, thinking that he was finally going to leave — and I was dying, thinking that he was going to leave! But he didn’t leave. When he got to the door, he threw the bolt to lock it. I was so angry, and so relieved!

Then he approached me as I sat in the recliner. I kept my mouth shut as he took off a shoe, then the other. He sat on the sofa and took off one sock, then the other.

When he stood up and began to unbutton his shirt, I shouted, “Stop it, Mack!” I repeated, “Stop it!,” adding, “I want you to leave now.”

“Do you? Do you really?”

I was sure I did, but I said nothing. I just watched him finish undoing his shirt, then flick it off his dark, broad shoulders. I was staring at his massive, sculpted chest. It was so beautiful, I thought I might faint.

Mack’s hands went to his waist. As we stared in each other’s eyes, he unbuckled his belt and undid the button; then down came the zipper. I was having trouble breathing. I didn’t know what to say or what to do as this godlike youth stripped in front of me.

His pants dropped to his ankles. He kicked his legs free, and there, standing a few feet away, I had this near-nude man with a body of rock-hard muscle that reminded me of a statue, a statue of a Greek god. Oh God, so much beautiful rippling muscle! He just stood there, not moving one bit, as if exhibiting his body, which was bare except for white jockey shorts, with a huge bulge in them.

I’m ashamed to say I was staring uncontrollably. I just could not take my eyes off that incredible body or that incredible bulge. I was thinking, no way do I want him to remove those shorts, I do not want to see what he has there, while at the same time a voice in my head was saying, I have to see it! Remove your shorts or I’ll have to rip them off myself!

“See,” Mack was saying, “I’ve wanted to fuck you since I’ve known you. I always thought you were the most beautiful woman I’ve ever seen. I’m going to tell you a big secret. This morning I had a talk with Lou — yes, your husband — and I came right out and asked his permission to screw you. You know what he said? ‘Go for it, Mack!’ That’s why he’s not here right now and I’m here standing in front of you in my underwear. We’re going to have some fun.”

I tried to get up, but Mack took one quick step forward blocking my escape. Only, I didn’t want to escape.

I watched in shock and fascination as Mack hooked his thumbs in his briefs and down came the shorts! What I was looking at now was unbelievable. I was thinking, That has to be fake, it can’t be real. But there it was right in front of me! A hard-on that had to be — I’m serious — ten inches long, with a head the size of a tennis ball.

“You like it?” Mack asked, then took a step closer, so the tip of his monster cock was almost touching my lips. My mouth remained closed as the tip of the cock made contact with it. My eyes never left it. My heart was beating out of control.

The next thing I knew, my mouth had opened and the huge cockhead was entering it. Ever so slowly, Mack fed me more, a fraction of an inch at a time, all that I could handle. It must have been ten minutes and he’d barely gotten the head of his cock in my mouth when he lost control and jets of come started streaming down my throat. I swallowed all of his delicious warm come.

When my husband came home, the first thing he said was, “Did you have fun?”
