My wife has recently undergone a major operation on her spine. As a result she has very restricted movement and we've put a bed downstairs as she cannot get upstairs. She has to wash in the kitchen with me helping. I enjoy this more than I thought that I would
Yesterday she was stood near the sink as I washed her feet and legs. She was naked of course. I was naked too as we often stay naked at home if we're not expecting visitors. It also saves me getting wet while washing her. I stood up from washing her legs and saw a guy in a tractor looking over the garden fence. He was cutting the grass on the field that backs onto our house and had stopped anlongside our garden gate. From his high vantage point he could see my wife's breasts in profile. Nothing from her tummy down though. I told her about him and she turned towards him and gave him a full frontal view. I covered my hands in soap and washed her breasts as he continued watching. This had got my cock rock hard, I always get aroused when washing her. I stood close behind her, supporting her of course

and rubbed my cock against the cheeks of her arse. She had her hand on her clitty and was masturbating. I'm sure that although he couldn't see what she was doing, he could tell from the movement of her arm. Before she could cum, whatever had caused him to pause by our garden had passed as we heard a couple of guys calling out and he carried on his way.
She continued madturbating until she came. So did I shooting my cum up her back.
She's always been a bit of an exhibitionist, normally when we are on holiday when there's no chance of seeing someone we know. This was the first time she's done anything at home. We've fucked on the patio, close by the house when neighbours have been in their garden. Unable to see us but present none the less. But never in plain sight of anyone.
