I fucked my first wife at 19. I was working at a house doing repairs to the hvac system and when I was done I told the home owner I would be right back in to get my work ticket signed. When I walked back in he told me to come to into the living room cause he had a tip for me, when I walked in his wife was naked in heels, I was caught off guard. She was in her 40’s. I felt weird but was extremely hard at the same time. He told me she was my tip. I was frozen wasn’t sure exactly what to do. I had never heard about this life style before. She came over to me and undid my pants she led me to the sofa . He sat down on a chair next to us and undressed. She climbed on top and rode me while he stroked his cock. After a few min I told her I was going to cum. She continued to ride. Me and I exploded in her.
