Her bladder. Time to go the other way through her cock.

Original Author: mazomune

As Kim stands over the toilet bowl, she expects to piss like a racehorse, but finds that it's just a trickle. Something is blocking her!

She pushes as hard as she can and contracts every muscle in her pelvis to **** out of her cock whatever is stuck. This, she thinks, surely has to be what's making her feel so ill.

You, meanwhile, are drowning at the bottom of her bladder, trying desperately to climb through. Fighting for your life with everything you have, you finally make it out of the bottom and climb through her tubes into her urethra. Kim enjoyed urethral play last time, but finds this agonising in her current state and pushes harder and harder until a giant stream of piss finally dislodges whatever it was. You're already saturated in her golden fluids and now they're attacking you like a firehose, blasting you through your sister's dick and eventually out of her peehole.

As you go further along her cock, Kim's feelings change from pain and horror to pleasant anticipation of relief. The thing in her cock almost feels good. It feels like that...other thing. Whatever it was, that made her happy last time. At the moment it leaves, she feels ecstasy.

You are being fired out of her cock like a torpedo. With all her ****, Kim has ejected you and you fly downwards, bombarded by a stream of dark yellow, smelly piss. Kim can't make you out in the mess down there and you land in the toilet bowl, still in the line of fire. Kim empties her bladder directly at you and you're knocked down into the bowl full of your sister's piss. It's disgusting, but not at disgusting as what you've just endured.

Kim breathes a loud sigh of relief at having whatever it was removed from her cock and enjoys a long hard piss. It feels so good after being backed up that it's almost like cumming to her, and she still doesn't see you being battered by her golden stream and struggling for life in the toilet bowl. Her eyes are screwed up and she focuses only on the feeling of catharsis.

It feels like about two minutes before her piss stream finally weakens to a trickle, and you're relieved when you can finally raise your head above water. Just as you try to shout out to Kim, no longer caring about the awkwardness or humiliation and concerned only with survival, she shakes the last drop from her cock, and a huge blob of piss lands unceremoniously on your face.

By this point you've realized something alarming. You've escaped being digested, but what if she flushes the toilet with you in it? You panic and try to shout to her, but your mouth is so full of pee that every time you open it you just **** and swallow. You have no way of contacting her, and you see Kim putting her cock back into her pants. You wonder whether she'll see you before she flushes the toilet, or if this is the end. You pray that you don't go like this.
