"What the Fuck?!" Princess screamed as I entered the bathroom.
She was naked, in the shower, the water cascading over her lush eighteen year old body. I had always called my stepdaughter "Princess" ever since we met when she was about 6 years old. Initially, it had been a tribute to her tiny perfect Disney blonde good looks. As puberty changed her attitude from sweetness to entitlement, the nickname had become overlaid with sarcasm.
Princess lived mostly with her father, since her Mom had abandoned them when Princess was just two or three, preferring a lifestyle of drinking and fucking around to domestic bliss. Not surprisingly, we had met in a bar, and she had gone home with me the first night. We had fucked like rabbits from then on, but my wife was not the monogamous sort. Fortunately, thinking of her body writhing around a hard strange cock just turned me on. Gradually though, we had grown apart and my sex life consisted mostly of my right hand.
Even with Princess only an intermittent visitor, it had not escaped my attention that in the past few years she had blossomed into a hot curvaceous young woman - a full round tight ass, a pair of pendulous tits that looked great in sweaters, doe eyes, a pendulous lower lip framing a mouth that begged to suck a cock. Not just any cock- in my fantasies, it was made to swallow my fat cock. I had jerked off to that fantasy many times.
My urges had become more urgent in the past couple of weeks. Princess had moved in with us, after her Dad had caught her fucking her boyfriend. I had met the young man, and bet he had a nice hard young cock. I would have loved to watch Princess suck that cock, and be fucked by it. Her real Dad though had told her she could not move back in until she promised to quit fucking. Since that was not going to happen, her stay with us was indefinite. We all bet her Dad, who had never remarried, would give in, but until then, our house had another resident.
Our one bathroom house.
"I have to piss really badly," I explained to Princess, "and my bladder got tired of waiting for you to run out of hot water."
Princess had clutched the shower curtain across her ample firm bosom, ignoring the fact that it was transparent plastic, so it did nothing to hide the view of the droplets dripping off her pink bubblegum nipples. Her movement just drew my attention to them rather than to completing my urgent task.
"Piss off," she spat back, "you can't just walk in on me when I'm naked."
"It's my house, I'll piss whenever I want to," I asserted. "And the way you flounce about, I've already imagined everything ten times over. Seeing your goodies for real is much less erotic than my imagination, trust me."
THAT got Princess' attention. She dropped the shower curtain, shoved it aside and turned to face me with her arms spread and feet apart. I noticed that she still had a wisp of pubic hair, matted by the water, but clearly matching her natural blonde colouring.
"Well, take a good look, then piss off... this is the closest you'll ever get to these goodies, so I hope you enjoy jerking off to the memories, you pathetic old man."
I felt an urge to spank her, but the urge to piss was more urgent.
"Piss on, more like it," I growled in response. "Piss on you, in fact."
As I spoke, I unzipped my pants. My engorged cock was weighty with the pressure of bladder fighting with my roiling balls, so it fell out into the warm moist air. In spite of herself, Princess took a good look, and I noticed that her lower lip quivered as her mouth dropped open just a touch.
"On your knees," I commanded.
