Four kids and not a single stretchmark? Now THAT is an accomplishemnt.
You go to the gym 6 days p/week and run umpteeump miles p/week, fuck your husband "properly" 3/4 times p/week and you still have so much free time that you feel the need to fantasize about "other men"?
Don't your children need volunteers in their school? Don't they need help with their homework? Don't they need you to bake cookies or read them a story or make their Halloween costumes? Maybe you could teach them how to play jacks or hopscotch?
The hell you say? You find time to do this, fuck your husband sufficiently and STILL HAVE TIME TO FANTASIZE ABOUT ANOTHER MAN?!
Well then, might I suggest that you get a fucking job? You will need one when your husband kicks your sorry ass to the curb.
PS - 115# at 5' 7" (I believe you said your were. If I am way off, I apologize) IS NOT VOLUPTUOUS. Prime real estate? I wonder if your husband would say the same if HE KNEW that you were busy fingering your pussy while other guys were listening w/a hard-on. Somehow, I think he *might* change his mind.
Also something to consider. What makes you think that the reason that "daddy is out so much" has anything to do with work and EVERYTHING to do with his passive aggressive distaste FOR YOU?
