I ignored it
We had a new hot tub and pool installed this summer. It's been great up until a few days ago. I covered the pool because it's fall but of course kept the hot tub going. We have had friends over in the evening's and it's always been fun. The other day my wife and her friend started early , drinking and having a good time. When the guys and I got there we all decided to hop in. Soon it was obvious that the girls were getting waisted , so my one friend took his wife home. Leaving me with my wife and two of my friends. I could tell that the guys were being sneaky and ( accidentally ) touching her tits. Once in awhile I noticed that their hands appear to be between her legs. I just sat there and watched as they became more and more bold. Then I heard our kid crying so I went in to check on her. Coming back to the back yard I stopped and froze in the window , my wife lay naked on the deck , her legs being held up by one of the them as the other stood in the hot tub fucking her. I watched as he shuddered obviously cumming in her. Then he feel back to the other side of the hot tub. The other guy let her legs go and pulled her away from the edge turned her on her stomach and mounted her. I was looking right at her face as his pace increased . I could see the look of lust in her eyes. Without even realizing what was happening I felt my dick start jumping and I began to cum in my shorts. When he was down. They helped her quickly get dressed and they all sat back in the hot tub. I rejoined them . 5 minutes later they said that they had to leave. Got up and dried off,got dressed and left.
