Happy Valentine's Day, bro! This should go without asking, but I'm going to ask anyway. Will you be my Valentine? You will? Yay! I'm so excited to be spending this day, a day to celebrate love, with you. After all, who else would I celebrate it with? You're the only one I love, bro. And I was thinking about what we could do to celebrate our love. The love that goes well beyond the "normal" love of two siblings. Maybe we could go out to dinner. Maybe we could take a vacation together. But then it hit me. The perfect way to celebrate our love! Brace yourself for this. Will you get me pregnant? Will you impregnate me, your sister? I know that people will talk, and they won't understand, but I've thought of a solution to that. We can run away together! We can go somewhere totally new where no one knows us and start our new lives with our own little family. So what do you say, bro? Is that what you want? You do want that!? You will get me pregnant?! This is the best Valentine's Day present I could have ever asked for! Just lay back and get comfortable. Let your sister get on top of you. Let's get me pregnant. I love having you inside of me, stretching me out with your big cock. It's like your cock was made specifically for my pussy. And it turns me on so much thinking about your cumming inside of me, depositing your huge load into my waiting pussy, against my waiting womb. Get on top. Make love to me like that, and cum inside of me. Cum balls deep in me and get me pregnant, bro.
