My loving Victor said he was tired and he went directly to bed in our room. He added he needed to enjoy a good siesta…Soon that old black man was si...ting close to me.I smiled at him, but he said not a single word. I could see his wet bathing suit up against his cock. His bulge there seemed to be very large and I could notice his cock was already hard.A while later I came back to our room. But Victor was not there…I heard some knock at the door. I opened and there was the same old black man from. The wife of the other couple had made comments to my wife about how great her husband was in bed, so my wife already had some interest in the husband, and in the past I had noticed him checking out my wife, and I had seen her act seductive around him. My wife and I had a lot of fantasizing about her being with another man, and we had specifically used him in some of our bedroom fantasizing.Shortly after we had arrived at the couple's house for dinner, the wife, who was a flight attendant, was. She then directed me to the room and let me change and shower. When she came back in she told me one of the new ther****ts would attend to me,... and because I have come back I could use the sauna for free, plus a drink of my choice. I quickly got my robe and headed to the sauna. A few minutes in there (all alone) i was obviously hot and getting relaxed.... Then i heard a knock on the door, and my ther****t peeped round and said she wanted to introduce herself and find out if i was ok. I. There before me was my mother in law lying on her bed with her eyes closed teasing her moist bald pussy and clit with one hand and playing with her tits with the other hand. I stood there shocked and at the same time beginning to get turned on. Here I was watching her as she moaned out loud bringing herself to orgasm and all I could do was stair at her as she finger fucked herself. As she hadn't heard or seen me I wondered if I should just back quietly out of the room or not, but all I could.
