took a shower, not noticing you in her half-awake state

Original Author: Mazomune

You're amazed at what you see before your eyes. Your younger sister Alice looks like she's 100 feet tall, and her hands, bigger than your body is now, look tiny next to the enormous cock she's holding. She's still semi erect from her morning wood, and her whole open hand seems to be only half the length of the giant schlong that reaches almost down to her knees.

As she finishes releasing the massive torrent of piss from her dick, she shakes it to get every last drop out, each one making a splash like a rock falling in the water. You try to get out of the bathroom as Alice finishes off her morning piss. She turns round, facing in your direction, and you get a full view of her colossal member. It's long and thick, with perfectly smooth skin and no veins. There's no hair above her cock, and below it are a huge pair of balls whose size is in proportion to her dick. They're held up against her pelvis by a tight, unwrinkled scrotum that also pushes her dick forwards. As she walks forwards, you're almost hypnotized by her cock swinging from side to side and making a loud slap against her thigh with every step she takes. At one level, you're disgusted by the idea of your sister with a huge dick that would make yours look tiny even if you weren't shrunk, but on another, you're mesmerized by this amazing sight and stare at it with your mouth open, unable to takes your eyes off the monster.

Before you know it, the world goes dark as her shadow is cast over you and blocks out the light. She walks right over your tiny body, not even noticing it, and heads into the shower. You know you shouldn't be looking at this, but you can't resist the urge and climb into the shower with her, hoping she won't notice and excited by the sense of danger. You scurry towards the front of the shower where you won't be hit by the water and feast your eyes on the sight in front of you.

The water hits Alice's body and makes it glisten, completely wet. The contrast between her petite, toned, cheerleading body, B-cup chest, and the gigantic beast between her legs fascinates you. It shares the tightness and smoothness with the rest of her body, but in all other respects it seems completely out of place and yet somehow alluring. All feelings of guilt at this intrusion into your sister's privacy have disappeared by this point, replaced entirely by excitement at what you see before you.

Alice rubs the shower gel all over her body, covering herself in the lather, and seems to take her time coating her huge cock and balls with it. Her soapy hands slowly make their way all down her shaft, which is so thick that she needs to wrap both of her hands around it. When she has reached the end of her cock and thoroughly covered her balls in shower gel, she squeezes along the length of her dick again. And again. It starts to rise and grow. You're so entranced by what you're looking at that it takes a while for you to realize the implications of what she's doing. Alice is jerking off in the shower!

The pink head of her girlcock peeks out from her foreskin as her dick slowly erects from the stimulation she's applying to it. Even though it's huge, and even though it's a dick, it somehow seems...cute. You keep watching as she continues to jerk it with both hands, starting slowly and gradually increasing her pace. With each jerking motion, her huge, tightly-bound balls are pulled forwards along with her cock. Now that you can get a proper look at them, you judge that they must each be at least the size of a large egg or maybe bigger. Her massive, hard cock seems to be about the length of her forearm, if not longer, and it's certainly thicker. You ignore your own hardening member, drinking in the sight of Alice's wanking.

She continues for a couple of minutes, and even though her smooth cock shows no veins or discoloration, you can tell that it's as hard as a rock and almost bursting out of her skin. Alice begins to moan with pleasure as her scrotum tightens even further than ever. The pace of her jerking has become frantic and you can tell she's nearing climax. You stand shamelessly in front of her with your eyes locked on her cock as she screams with ecstasy and her cock pulses. She lets out a huge spurt of thick, white jizz that plasters the wall directly behind you, and a new rope of cum accompanies each yell of joy. Her orgasm is intense and seems endless, lasting far longer than yours. With a final groan, the last spurt of cum lands directly on you, knocking you down near the plughole as an exhausted Alice catches her breath with a huge smile on her face and rinses herself off.
