no problem
the next target is friends and family get togethers as long as you look better then your buddy then chances are you can fuck his wife
the easiest way to get to this point is to just ask her right out when he goes to the bathroom
say "hey you know I have been wanting to fuck you forever" be sure to look her right in the eye
if she says nothing when he comes back congradulation

you should be fucking your buddies wife in no time at all
