Sexual orientation :
Ok, so you tell us she is asking for cum from her hubby and he says not tonite.
And you video tape her in the shower with a cell cam left behind.
Its simple dude, if you live with her and her husband, your soon to be wife's parents so to speak, either you or them are saving up money to move out or you are flat broke. So, if you dont mind fucking up your relationship with your fiance', go ahead, leave the door open to the room you are in looking at porn, pull out your cock and fap it when she is home alone. Eventually she is going to walk in on it, and either she will run and hide and not bring it up, OR she will say something that will turn the corner so you can fuck her or at least fill her throat with the protein she craves.
But you may end up more broke and out on your ass, so weigh it out brother.. be smart
