You looove stroking to my photos- even though you’re my step-brother. You can’t help it- you’ve been obsessed with your step-sister’s big boobs for YEARS! But today, your masturbation session is interrupted, and I discover your dirty secret! But instead of storming out, your bossy step-sis decides to help out, and makes you continue for her entertainment- she wants to order you around, tease you, and direct this session, because she’s been fantasizing about you, too.
