I can tell you've got something on your mind sis, what's up?
I'm not sure if I can trust you...
Come on you know you can trust me!
Fine... I need your help... Could you maybe buy me some condoms?
What?! Why do you need me to buy you condoms?
I'm just embarrassed to buy them on my own.. please bro!
I guess, but you're going to have to help me out with something too...
I want you to blow me, and I won't tell mom that you asked me to get you condoms...
We shouldn't do this... you're my brother!
Watch me trick my step sister into taking my big cock in her fresh tight pussy.. she thought she could get away with just a blowjob, but I need more than that to keep my mouth shut and not tell mom how much of a slut her sweet daughter is.... Unlike my sister's boyfriend, I don't need to use condoms to fuck her
