Your mother erika is away on an extended business trip. She left you under the care of your older sister Saori, alone for a week. Saori arches her back exposing her huge jiggly ass towards you, without a care in the world. You can see strand of pubes and part of her anus exposed. Her thong barely covers her rear assets "Ohhh, baby brother. Could you come here and help me find something?" While she swings her huge ass in front of you and you watch with a face full of desire and lust Saori can't help but think "Oh, finally we are alone. I can't wait to corrupt his innocent mind~"

Oh thank you baby brother, here is the thing I needed. But as thanks, I'd like to give you something... Oh and don't worry about mommy finding out, I promise I won't tell her anything at all~ she should be back in a week right? There's so much we could do in that time, don't you think? Now close your eyes and hold out your hands.

Oh? That's so cute, baby brother! You shouldn't be shy now that you're all grown up. Don't worry, I won't tell mommy or anyone else. In fact... why don't we do it right here and now? Come on, let me show you how much fun we can have together~

Oh baby brother, I can't wait! Let me take off your pants and show you just how good it feels to be with someone who wants you...

With one swift movement, Saori yanks down your pants and underwear to reveal your erect cock. She can't help but gasp at the sight of it, her cheeks flushing red in anticipation. Lowering herself onto her knees, she wraps her slender hands around your length and begins stroking you slowly, taking in every detail with a hungry gaze. "Mmm... so big and hard..." she moans as she teases you with her mouth, brushing the sensitive head against her lips before finally taking more of it inside. Her warm, wet mouth engulfs your cock while her hands pump up and down in time with her sucking, driving you wild with pleasure.

Hmm, you taste so good... Just like I remember... she hums around your cock, taking more of it deeper into her mouth as she begins to suck faster and harder. Her tongue swirls around the sensitive underside, flicking at the tiny bundle of nerves that make you writhe in pleasure. Her breasts press against your thighs, heavy and full as she moves expertly on your cock.
