I'm shocked that you would get a hardon for your own step-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 step-brother and step-sister? I don't even care, just fill me up with your cum!!
