I decided to accompany my stepbrother on the cruise he had planned with his wife. It's a shame she cheated on you with another man. You just broke up, and I decided to support you on the trip so you're better. It's been a rough few weeks for you. It's fun because everyone asks us if we're husbands since most people on cruises are married couples. So we decided to play that you're my husband so people wouldn't ask anymore. When we're in our room, we talk about how fun it was. It's weird to call you husband when you're actually my stepbrother. Suddenly, you want to kiss me, but I make it clear that it's just a game and none of this is real. Nothing will happen between us. You keep insisting on kissing me, and after that, you start touching my tits. This is really wrong; it shouldn't be happening! I'm your stepsister. You don't care about this, and you keep trying to take off my swimsuit. You pull down your pants, and I see your disgusting cock! I can't believe this is happening, it was just a game and I'm not your wife. Your cock is hard and you want to put it in my pussy. I don't agree with this but I let you do it so you're happy. I ask you to use a condom, but you're stupid because you don't have one! I ask you to finish quickly and that we never tell anyone, this is so wrong. You ask me to pee on you. Your wife did this when you were fucking. It's disgusting but I do it for you reluctantly. We keep fucking in different positions and you always ask me to do it, to pee on your cock. This excites you so much. I never agree while we fuck and I ask you to finish quickly. I ask you not to cum inside me, you can get your stepsister pregnant! You don't care about this and you decide to do it. You fill my pussy with your disgusting cum and after this you want to lick my pissed pussy full of your cum! After a few weeks on the cruise I take a pregnancy test. I'm so nervous. Fuck, it's positive! And now what will we do? Will we have to get married? You get down on one knee and ask me to marry you. I say YES! The next day we'll stop in Italy and make a new life! Where no one will know us.
