Dormering is the process of bringing a lover to a bedroom or any room in-fact where you have a dormer window with a view. This is not to be mistaken with veluxing which is not to be advised.
By showing you lover the view through the dormer window you can proceed to sex her, taking her by surprise.
I had a well good dormering last-night. Took this girl up to my top floor flat and showed her the view, she was gushing all night!
