First time writing a scene [MF] [married] [cumshot]

Greetings. This is my first attempt at writing down an encounter. Please let me know what you think.

It had been over a week before I had a chance to blow my load, see we just got a puppy dog and all my wife and I have had time and energy for was him. Beings as it was so long since I was able to be intimate with my wife (2 months due to illness and puppy) my mind began to wander. By the time Sunday rolled around I had a full experience ready in my mind.

Sunday evening came up and we had some time while the puppy was in his crate, my wife and I were sitting watching TV and we decided that NIW is the best time to get to know each other. I led her to the guest bedroom and put on a movie for the puppy to listen to, just in case we got a little loud.
