just remember you are just a toy for her, her husband is probably banging away everything with a pulse on these trips, but comes home being a loving husband, like most married men on this forum that punt behind their wives back,
so enjoy it, but set yourself some rules,
always use protection,
don't call or text her, let her call you
never go to her place, neighbours will talk
never approach her on the street even if you think she is alone, someone will recognise her and tell the husband
never meet the kid, kids have big mouths,
and if she wants to buy or pay for anything, tell her not to leave an electronic trail,
