As I held the door open I saw him. The big male Doberman was in the middle of the yard looking at me. I was frozen staring back at him with just my sh...rts on. I could see him sniff the air and then cock his head to the side which meant he was interested in something. I saw him sniff again and his ears picked up and he shuddered a little. Could he smell me? Was he still interested in this human female? I had to know so I took off my shorts and tossed them over to where my shirt was. I stood. She arched her back a strange hand on her fine ample tit gripping hard the man half under her allowing her body to bounce up then down on his big frame. In her ear she could feel his breath as he gasped in enjoyment.“That’s it baby take it all, take it all inside!”The world was coming back in a flood and she gave another groan of horror realising her legs were up and apart one hooked under the man’s arm her toes pointing skywards. She made a long “nooooo” sound of refusal. Her head shook, her. What an erotic sight we were all watching, my wife laying on her back with her legs over a strange guys shoulders while he was fucking her with his huge cock and playing with her tits and sucking on her nipples. I was actually stroking my cock thru my pants I was so excited and I knew the other guys were too, we all seemed to be mesmerized by the incredibly erotic scene we were watching, a scene that my lovely wife was the star player in.The young masseur continued pounding his cock into my. .. On my bed lay a jacket an England rugby shirt, a white pleated skirt, hold up stockings, earrings and some trainers...no underclothes what so ever!I knew not to ask, and adding the usual dab of perfume I dressed and returned downstairs. I was just in time as an 8 seat people carrier appeared at the drive entrance driven by Ray. We locked up and went to the motor, where Ray loaded the overnight bag into the boot, checked we had our passports then bade Andy ride in the front and told me to.
