Blonde forced to fuck to pay the rent
One day she realizes that the world she believes is real is not. Where she lived before, everything was free and there for her to enjoy, now she realizes that she has to pay for things and that contracts must be fulfilled. Therefore, she is forced to fuck to pay the rent. It does not have money, which is what is traditionally used, and so it has to make some of the oldest currency in the world. And after the guy has tasted her pussy, surely never again in his life will he want to touch the filthy money that she can offer. Obviously he will want to continue fucking her.
