If i could trouble any one online for some advise i would appreciate your time.  Long story short.  After an extremely long week  i threw a huge temper tandrum last night.  my Wife took me into the bed room and told me if i was going to act like a bitch she was going to fuck me like one.  She then proceeded to fuck me up the ass while she drank a beer.  She then told me to get cleaned up and go to bed.  (normally after i get it up the ass she will let me jack off or sometimes i can feel her pussy.)  i am so ashamed of the way i acted and so proud of the way she handled it. 

my question is how would you suggest i appologize properly?
