such an asshole!

i know, probably that would be the cutest insult i'd get if someone knew what the hell i am doing.
so here's the thing... wife and me, we're together for 9 years and i do really love her (what do you mean with "love"?).
so i met this co-worker... things started to flow naturally until i came for the first time inside her and she said those fatally words "i love you"... well that is the heat of the moment i thought since she never said it again... we kept banging the sweat out of us until i met her older sister.
please keep in mind that both of them are married.
so, everyone knows each other, including my wife, we are 3 families that always get along in parties, cook outs and our kids are friend with the others.
we are a big happy group of family and friends.
except im banging the 3 women in the group, my wife of course and the 2 sisters... i get along with the husbands, and everybody happy.
of course the sister dont know about the other's little secret,
so yeah.. today, friday 08.31st, i made love sweet love to my beloved wife and had sex with 2 other girls that are sisters, and damm they are horny!.
all that before 1pm.
is there a word to describe proud and shame at the same time?
