Your little sister comes into your bedroom complaining about bad dreams and a weird noise in the house "I just feel safer beside my big brother." She cuddles up next to you "that's the sound again! Why are you laughing?" You explain it's the sound of mom and dad's bed squeaking while they have sex and she giggles awkwardly. One thing leads to another and suddenly you're on top of your sister, caressing her cute little body through her pajamas as she smiles and moans. She gasps as she feels your hard cock through your underwear and asks if she can try sucking it. You show her how to lick the tip and gently play with the balls... she's feeling adventurous and even tries sucking your balls. "Are you gonna fuck me?" She looks at you hopefully and you give her the go-ahead to slowly lower her tight teenage hole onto her brother's throbbing cock. She bounces up and down a little, getting used to your size before you turn her around for some doggystyle. Then she asks you to flip her on her back so she "can know it's her brother fucking her." She starts to talk about how it would feel to be creampied by her own brother and that's when you lose it, giving her a deep creampie in her sweet pink pussy. "I think I'll be having a lot more 'bad dreams' from here on" she giggles.
