It's the morning of my wedding and you've agreed to walk me down the aisle instead of our dad whom I'm feuding with. You pop up behind me when I'm trying on some lingerie which causes me to snap at you. I immediately feel regret and tell you I could use a "male eye" to pick out an outfit for my special night. There was no time for me to purchase new lingerie so everything I have is old, which adds to my distress. Before I change, I remind you to close your eyes and without my knowing, you continue to look on in arousal at my nude body. After I try on my final piece, I notice your erection. You WERE looking! I'm shocked that you would get a hardon for your own sister. Don't you know how WRONG this is?! You're embarrassed and blame it on your girlfriend whom you haven't had sex with for months and then proceed to blame me for being so hot. You can't walk me down the aisle with an erection!! You need to take care of it, now!! If I have to help, I will, I guess. Wow though, you're huge...much bigger than my fiance... My tits are much bigger and nicer than your girlfriends, I know. Say, a handjob wouldn't hurt, right? When is the last time she put it in her mouth...? We could try that too... Or maybe a titjob? Oh fuck it, let's just have sex already. We are a man and a woman after all. It's only natural that our bodies are reacting like this! Can you believe we're both cheating on our partners and having intercourse even though we're brother and sister? I don't even care, just fill me up with your cum!!
