After her first threesome (BBW’s first MMF) my mrs has been quiet but hornier than usual. It was a massive step to get her to swing at the hotel so I never imagined she would be as spontaneous as last night. At about 9 last night, kids long in bed asleep, there was a knock at the door. She went and answered it returning with a young lad who was doing some kind of consumer survey. It was wet and windy out so I guess she felt sorry for him. As soon as he sat down she was obviously flirting with him. She offered him a drink and went into the kitchen, I followed her leaving the survey lad in the living room. “You’re flirting with him babe” “Am I?” “You know you are” I was fondling her arse while we chatted, she felt me getting harder so I slipped my hand up her skirt and inside her panties. She was getting wet and through her top I could see her long nipples becoming erect. I whispered an idea in her ear, she smiled, spun round on her heels and headed for the living room. Arriving there she knelt in front of him, removed her top, and put his hands onto her 42D tits. She found his zip, undid it and took out his cock. He easily had a good 8 inches and was very hard. She pushed her ample arse out towards me and went down on him. I raised her skirt, pulled her pants to one side and sank deep inside her. She was taking him very deep, he sat there with his eyes shut and his hands gently on her head stroking her silky straight dark hair. I fucked her as slowly as I could, I wanted to enjoy this. It didn’t take long before his breathing changed and he tensed up. I started to pound her harder now. I can never last too long when behind her, I love her arse and seeing her dark hair brushing her pale white back and shoulders makes me lose control. I could hear her gulping down shot after shot of his cum as I filled her from behind. She got up and sat down next to him and calmly said “What’s this survey about then?” Poor lad didn’t know what to do next so he very hastily put his tackle away, gathered his stuff and left. “Shame that” Said the wife, “Was going to invite him upstairs and ask if he wanted my ass while I straddle you. Quite fancy getting a DP soon” No doubt she will make it happen.
