I fondled Katie’s fully developed bosom with my free hand while continue to stimulate her under the water. Tweaking her nipples slightly harder than her clit seemed to really get her going and she started rubbing her ass against my throbbing erection. I increased my tempo and her breath grew shorter until she was holding her breath, completely still, fully focused on my fingers.
“Oh my god, daddy, I’m cumming!”
I kept working my daughter’s clitoris as she orgasmed, her moans echoing off the bathroom tiles as she grabbed the sides of the bathtub and shook with uncontrollable pleasure.
“I love you daddy!” she cried as she reached her peak.
“I love you too, baby.”
Katie thrashed in the tub as the euphoria of the moment overtook her and it was a full minute before she stopped shaking. I slowed down my movements while she was coming to keep her up there as long as possible. Enjoying the afterglow, she shifted positions, rolling over onto her side and resting her check on my shoulder.
“That was amazing, Dad. I loved it!” she purred, stroking my chest.
“I’m glad.”
“Best orgasm ever!”
I thought things might be awkward after we had both had orgasms and our horniness subsided. But it just felt natural, and the horniness didn’t subside. I still had a massive boner which Katie kept grazing as she shifted positions.
I had a feeling more fun was coming.
“Daddy?”
“Yes baby girl?”
“Do you think could clean me on the inside?”
“How do you mean?”
“You just cleaned the outside of my pussy, but you haven’t done the inside yet?”
“Like this?” I asked, slipping my middle finger into her soaking wet vagina.
“Mmmmmm… yes daddy, just like that!”
I fingered my daughter without restraint for the next few minutes, savoring her slipperiness and the way she gripped my arm a little harder and moaned a little louder each time I penetrated her needy vagina. Just as my deviant daughter was nearing a second, even bigger climax, we heard the terrible cry of her mother.
“Jack, Katie, where are you?!”
“We’re in here, Mom!”
I was shocked.
“Katie, what are you doing?”
I tried to pull my finger out but she held my hand in place and told me to keep going.
“We’re just having a perfectly innocent daddy-daughter bubble bath. Mom is so gullible she won’t suspect a thing. Keep going daddy. Don’t stop now. You were about to make me cum.”
“What are you two doing?” exclaimed my wife in her usual uptight manner as she entered the bathroom, looking down her nose in a familiar, disapproving glare.
Thankfully Katie was ready for this conversation.
“You said we needed to save water so daddy and I are taking a bath together.”
“To save water?” asked Sally, raising a skeptical eyebrow.
“You did say that we should save water, didn’t you?”
Sally remembered what she had said. Maybe Katie was finally taking her criticisms on board, although a bath with her own father was not something Sally had considered.
“Don’t you think you’re a little old to bathing with your father?”
“I’m eighteen Mom, it’s time for me to start taking responsibility for the planet.”
Throughout the conversation, I continued slowly easing my ring and middle finger in and out of my daughter’s slippery snatch and Katie had used the excuse of her mother’s arrival to shift her position so that I could penetrate her even more deeply. The bubble bath completely covered what we were up to from sight and her mother seemed totally taken in by her arguments.
“Alright then, but next time you should just take a shower, it uses much less water than a bath.”
“Great suggestion Mom! Thanks for the tip!” said Katie cheerily, grabbing the top of my dick as she said the word tip, secretly ridiculing her bossy, overbearing mother.
“I’m going to the shops now, enjoy your bath together!”
“We will!” sung Katie and I in unison as her mother departed.
My wife really was a very gullible woman.
I don’t know why, but my daughter started making out with me then. She must have been really hot and horny from the steaming bath and everything that was happening underwater because she kissed me like we were lovers rather than father and daughter.
“I think its time we cleaned your dick again daddy?”
“Really?”
“Yes, daddy, but I think we should use my pussy this time…”
Katie didn’t wait for a reply. She just got onto her knees facing away from me and then sat back, reaching around to position my cockhead so that it was pressing against her opening. The water in the bath had started cooling down and the foam was disappearing, but that only made what we were doing even hotter. I savored the sight of my daughter’s peachy ass through the clearing water, marveling at the way her pussy lips parted as she impaled herself on my penis.
“Fuck daddy! That feel amazing!” she cried as she slipped to the bottom.
I didn’t say anything. I just grabbed my daughter’s hips and started fucking.
Water splashed everywhere, wetting the entire bathroom floor and running under the door and into the hallway. Now that Sally was out the house, Katie started screaming loudly.
“Fuck me daddy! Fuck me daddy!” she shouted at the top of her lungs until most of the water in the bath had been deposited on the bathroom floor and all the bubbles were gone.
I did as I was told, plunging my penis into my daughter as water sloshed around us and her wet ass slammed against my pelvis with unrelenting vigor. A powerful sensation coiled in my loins, like an electric storm, as I neared the limits of my stamina. Katie continued screaming for me to fuck her, gripping the sides of the bath as she gave in to the debauchery of the situation, leaking juices all over my cock in the pursuit of another orgasm.
It was far too much for any man to handle and I roared that I was about to come.
“Yes, daddy, cum inside me!” howled Katie as all my deepest needs and darkest desires were savagely unburdened deep inside my delicious teen daughter. Katie’s pussy contracted around my ejaculating penis as we came in unison. Father and daughter. Incestuous lovers. My cream filled up my daughter’s pussy until it poured out and coated her inner thighs, although we just kept humping, forcing my semen deeper and deeper inside her.
We needed to take a shower after our bath to clean ourselves. There was cum everywhere, all over my dick and balls, all over Katie’s ass and pussy and all over the tub. Then we had to clean the bathroom floor and tumble dry the towels to make sure Sally never found out about what had happened. Although, I knew Katie wouldn’t mind. She had said it herself. If her mother left, we could have bubble baths together all the time.
