Young Slut/Walk into your sisters room
Your heart starts to pound as you realize what you're about to do but you don't care, naked and all you walk out of the bathroom and open up your sisters room to see her on her desk doing her make up looking at the mirror, she's wearing a white robe which doesn't exactly cover much of her body when she turns around frightened by your sudden entrance with her robe completely open. You can see her unshaven pussy and her C-Cup breasts poking out of the robe.
"What are you doing in my room! Also why the fuck are you naked?"
I quickly respond with "Sis I really need you to help me cum, I want you to grind on my pussy and suck on my clit and all that, just make me cum please!"
She looks me up and down and seems to go deep into thought until she blurts out...
