Of course! I love my toilet slut.

I ruffled her hair and chuckled. “Don’t worry sissy. I can take care of you.” She smiled, knowing exactly what I had in mind.

You see, new technology didn’t just enhance the woman, and I had some of that technology in the bathroom medicine cabinet. I dashed out of my sister’s room, and entered the bathroom. I took a small yellow pill, and drank as much water as I could. I could feel the piss filling my bladder as I walked back into the bedroom where my piss mop sister was excitedly awaiting me.

I straddled her perfect thighs, all bound in fishnet, and aimed my cock at her pussy. After years of pissing on my whore of a sister I had become quite competent at blasting her cute little clitoris with a strong stream of pee. She bit her lip to hold back a moan as her body contracted in orgasm. She wet herself again and rubbed the mixed urine up and down her body until she had come down.

I was still full of fresh piss and knew exactly where to put it. I rammed my cock into her pussy and pumped her full of piss. She almost had enough strength to tell me she had too much, but another orgasm shut her up. At least I assume she was going to say too much. I only guess that because the pressure was so much that it started leaking out of her tight pussy.

Trying to stop peeing was hard, so I decided not to, and instead just switched holes. Her asshole was a convenient 3 inches away and could hold much more piss. As I swapped holes, a burst of hot piss flooded out as she moaned from the release. Her fingers quickly took it’s place, capturing a more manageable, but still fulfilling amount of piss in her pussy. Her ass was tighter, but was more capable of loosening up as it was worked, and worked it was!

I squeezed her perfect breasts as I filled her ass with cock and piss. She wrapped her legs around my waist trapping me in place. After several minutes of pissing I was empty. After some panting she grabbed me by the shirt and gave me an exhausted sloppy kiss, and muttered a thank you. I left my piss filled sister smiling and satisfied.
