Into the bathroom to get ready. (cw piss drinking)

We headed into the bathroom down the hall, Sara holding her hand under her messy pussy to keep my cum from dripping all over the floor. There were a few stains here or there around the house but my sister had made a point of making sure Sara didn't let any spill on the carpet if she could avoid it. We entered the bathroom and flip the lights on. The room was typical for a house like this, with tiles on the floor and a small bathtub against the wall. I gently lead Sara into the room and guide her to the tub.

"Come on," I told her as I gently push on her shoulders. "I really need to go."

"This sucks," she complained looking at me annoyed. "I get that this is normal but I don't like it at all."

"I know, but I need to piss somewhere and your mouth is as good a place as any."

I grinned as she opens her mouth while I lined my cock up to aim the tip at her throat. Normally I'm not one for this really kinky shit, but one day after blowing my load in Sara during our morning shower I had to piss, and while letting it go into the shower my niece really freaked. When you can get away with basically anything like I can getting reactions like that is rare and really hot. From then on I constantly pushed her out of her comfort zone when it came to me peeing on her. Having her drink it in the mornings was new, but so far was proving quite fun.

After getting a good aim I let loose with a sigh and a steady stream of piss flowed into my niece's mouth. She swallowed as fast as she could, a grimace on her face as she did so. She didn't quite swallow fast enough so a lot dribbled around her mouth and onto her body. I can't deny there was something hot about the sheer depravity of it all. After a moment my stream turned into a trickle and I pushed the tip of my cock into her mouth so the last few drops would flow into her throat.

My cock started to harden, both at the sight and at the feeling of her mouth around the tip so I slid a bit more inside and placed a hand on the back of her head.

"Suck me off," I told her, using my hand to **** her head up and down my cock. Sara gagged lightly around my hardness but dutifully sucked as best she could. After a month of using all three of her holes, she had gotten pretty good at it. Having already blown out my morning wood it did take a few minutes to work a new load out of my balls but soon I was washing the taste of piss out of the young teen's throat with the taste of my cum.

"~Ack~ all set?" Sara asked sullenly.

"Sure," I shrugged as I stepped into the tub and turned the shower head on. "I might fuck your ass a the breakfast table though so be sure to wash back there, and use an enema after we're cleaned."

"Fuck," Sara muttered before she stood and helped to wash my back. "I really don't like those, and I hate it when you use my ass."

"I know, but it can't be helped can it? It's just a normal thing for me to do."

"Yeah," she sighed. "I know, totally normal stuff, but still."

I smiled over my shoulder at her. "But nothing, now come closer so you can wash my cock from behind."

"Yes auntie."
