One day I came home from work and found my wife in our hot tub with her male co-worker. She was sitting in between his legs and he was giving her a massage. He had her bikini straps untied and the top was barely covering her tits. When I let them know I was there they made no inclination to stop so I told them I was going inside to take a shower and went back in the house. When I was done showering I looked outside and they were getting out of the tub. My wife had on a thong bikini and her friend had on his boxers. I could clearly see he had a massive erection and noticed my wife staring at it. They hugged each other and his hands found the top of her ass cheeks as his dick poked her stomach. Even though I know I should be mad about this I can't help but be turned on by it. Is that crazy??
