Every day after school we always get together in your room to 'study'. Or at least that's what we tell my step-mom. What we really do is have some step-brother/step-sister bonding time. We made a deal that you get to jerk off and relieve yourself onto my mouth because.. it's not actually touching each other right? I always get so excited for your huge load each day. It gets bigger and bigger for me and my pretty face! I even encourage you to jerk off on your step-sister's pretty mouth!
