Knock at the door

"Who is it? You ask. Without warning the door burst open.

"God I have to pee!" Your sister Nikki says as she rushes to the toilet. She gives you a quick look as she walks past you. "Nice ass baby brother!" She says as she pulls out her dick and starts peeing. You can't take your eyes off it it's 9 inches long and 4 inches wide. Your jaw drops open slightly. You have to **** yourself to look away hoping she didn't catch you.

"Shut up your only 2 minutes older." You say as you turn back toward the shower. You feel a hand on your hip and you freeze.

"Saw you checking my size.... It's impressive ain't it." Nikki says as you feel her large dick slide between your thighs. You look down and see it below your own. She shuts the door and brings her other hand to your ass. " Your still a virgin... Haven't been claimed yet it's so sad with a pretty little thing like you." She slide her hand down into your ass and starts rubbing your boipussy. You bite your lip as her finger enters you.

"Stop." You say softly but you can't help but raise your ass to give her better access. She softly fingers you as she brings her other hand slowly up your chest and sticks it in your mouth and you suck on it slowly.

"You don't really want that now do you?" She asks while she fingers you. "So baby brother where do we go from here?"
