So, tomorrow's the big day! Your wedding to my step-sister! Are you nervous? Honestly, I never thought you were the kind of guy who would settle down. I thought you wouldn't be able to survive with just one girl, one pussy, for the rest of your life. You always seemed like more of a player to me. And especially a guy as hot as you, you could have any girl you wanted! I'm really surprised you want to just be with one girl forever. Wait ... you're staring at my tits! I knew it! You're not even married and you already want to have an affair! Honestly, I don't mind. Want to know a secret? Ever ...

So, tomorrow's the big day! Your wedding to my step-sister! Are you nervous? Honestly, I never thought you were the kind of guy who would settle down. I thought you wouldn't be able to survive with just one girl, one pussy, for the rest of your life. You always seemed like more of a player to me. And especially a guy as hot as you, you could have any girl you wanted! I'm really surprised you want to just be with one girl forever. Wait ... you're staring at my tits! I knew it! You're not even married and you already want to have an affair! Honestly, I don't mind. Want to know a secret? Ever since I turned 18 I've been a home wrecker. I ruined my principal's marriage by letting him bend me over his desk. And I ruined my step-mom's marriage by seducing my step-dad. Now I'm going to ruin my step-sister's marriage too. Do you need an excuse? You can think of it as if we're doing my step-sister a favour. I mean, you're going to cheat eventually. You're just that kind of guy. It's better to get it over with now before you're actually married. Or think of it this way - cheating on a girlfriend isn't as bad as cheating on a wife. That means you HAVE to cheat on my step-sister tonight. Still not convinced? Then do it as a favour for me. I really, really want your dick. I think your hot as fuck and I've wanted you inside me for a long time. I know you can't resist me. You have a stunningly gorgeous, barely legal girl right in front of you begging for your cock. Do you really think you can say no? Just give in and CHEAT! I get on my hands and knees and beg you until you finally give in. You fuck me in doggy until you shoot your load inside my 18 year old pussy. See, wasn't that totally worth it?
