I'm your wife's sister and had to move in with you two after my recent divorce. My divorce happened because I already had a pregnancy which turned out to be yours and not my husband's. Now you've knocked me up again, and I'm pissed. I can't stop belching as I sit there cussing and complaining. I'm so angry that you won't stop cumming in me with your ridiculously huge cock. You begin to get hard and eventually pull out your dick which makes me even more annoyed. I pull out my tits and play with them as I continue to tell you how annoyed I am. Finally I climb on top of you and ride you while still belching and dirty talk about how big your cock is and how my tits are bigger than your wife's. I tell you to cum inside me since I'm already pregnant, then lay there burping and talking about how much you came and whatnot.
