Pervert13: Start on her pussy
From Create Your Own Story
You ease your sister off your dick and smile at her saying, "All right, it's time for your pussy to get fucked by this big dick." Your sister stands up and you lead her upstairs to her bedroom and have her lay on the bed with her legs spread, showing you her even wetter and more aroused pussy. You touch her throbbing pussy, making her cry out and then you ask if she wants to fuck your big dick and she says "oh yes please, your big sister is a nasty little slut and she needs her brother's big dick in her pussy".
You hold her legs and push your huge dick into your sister's pussy making her whine as it penetrates her deeper and deeper, reshaping her insides to fit your massive girth. You start fucking your sister's pussy slow but hard making her see stars as you stab your huge dick again and again into her body.
You roll your head back and start fucking her even harder groaning as you feel your sister's pussy stretched tight across your huge dick desperately trying to suck it back inside. Your sister arches her back and says "oh... god... fuck!" as she cums and you grab her arms behind her back pinning her so you can fuck her even harder. When her arms aren't good enough you grab her hair and yank back on it, arching your own back as you drill into your sister's steaming cunt, your sister not even noticing the pain, or anything else but the feeling of your huge dick making her cum. You tell your sister she's going to be your big dick's slut just like all her slutty little friends and she cries out as she cums again. You bury your dick in your sister and spew your hot cum into her body, your huge balls vomiting up load after load through your swollen gushing shaft into her helpless battered pussy.
