The party was humming along and I was having a great time which was a surprise considering that I did not want to be there in the first place. I'd just come back from an exhausting business trip and was looking forward to a restful weekend doing absolutely nothing. My wife, Brandy, reminded me that I had promised to take her to a birthday party for her best friend on Saturday so I kissed my peaceful weekend goodbye and here we were. Brandy was having a good time too and, as usual, she had more male attention than I cared to see, but I trusted her implicitly so I did my best to ignore it. Rhonda, Brandy's best friend since the third grade, and her husband Paul, really knew how to throw a party so I was a little surprised when Paul came up to me and asked me for a favor.

"We are running out of ice and I feel obligated to stay and be host. Could you go and get some?"

I thought about it for a moment, the closest store at this time of night was over half an hour away, but what the hell, why not? I said I'd go. "Let me tell Brandy what's going on and I'll get going."

About half a block from the house I remembered that I didn't have any cash on me and that I'd used the last of the checks in my check book while I was on my trip. I turned around and went back to the party thinking I'd get some money from Brandy. I went through the side door and as I wiped my feet in the mud room I could see into the kitchen and what I saw was Paul with his hand inside Brandy's dress and Brandy rubbing the bulge in Paul's pants. I heard Paul say:

"Lets take this to the bedroom" and the two of them headed off.

I started to go after them, but for some strange reason that to this day I don't understand, I stopped. Paul's house was a single level ranch style so all the bedrooms were on ground level. I went outside and circled the house until I came to Paul and Rhonda's bedroom and I was in luck - the blinds were not completely closed. I got there in time to see Paul step out of his pants and Brandy throw her panties on the bed. She knelt on the edge of the bed and Paul moved in behind her and pushed himself into her. They had been fucking for about two minutes when the door opened and Rhonda came in followed by Paul's brother Jess and a man I knew only as Harv. Jess unbuttoned himself and pulled out his cock as he walked over to Brandy; he stuck it in her face and she did not hesitate to open her mouth and take it in. It may sound strange, but the only thoughts going through my mind were:

"How long has this been going on?" and "Why hasn't Brandy told me about this?"

I admit it! I was turned on - big time! I watched for about an hour as Brandy and Rhonda fucked and sucked the three men and I was still whacking away on my stiff dick as the five of them started to dress.

I went back to the party and made up a bullshit story about having a flat tire, finding the spare flat, and then having to wait so long for road service that I figured the party must be breaking up so I skipped getting the ice. It was a quiet ride home that night, as I usually don't like to talk when I drive because I don't like being distracted. When we were home and in the bedroom undressing I waved my hard cock at Brandy and told her that her night wasn't over yet. She said she was really tired and didn't feel like having sex. I looked at her and said:

"You spend over an hour fucking and sucking Paul, Harv and Jess and you're going to tell me you don't feel like having sex tonight?"

All the blood drained from her face and she turned pale white. I turned away from her and hung my clothes in the closet and when I turned back she was sitting motionless on the bed. As I walked toward her she tearfully asked me what was I going to do.
