I have no idea what the hell happened yesterday.
The only possible explanation I can think of was that we've recently drilled a new well for our water supply, and that was the day it went active. We live a good distance off the main grid, so we can't depend on the city for our water. It had taken a lot of testing (and a big wad of cash, let me tell you), but we finally found a nice, clear source of potable water about a hundred yards west of the old well.
So maybe there's something in the water. Or maybe that's just an excuse for our...odd behavior. But things changed that morning, in ways I just never expected.
My daughter Kayly is a senior in high school, just turned eighteen. That morning she came into the kitchen in her terrycloth robe, fresh from the shower, and I could tell that she was wearing nothing underneath. That made me feel unaccountably jolly for some reason. I watched intently as she gulped down half a glass of cool spring water. "That tastes really good," she said, grinning, "lots better than the water from the old well." As she leaned over to set her glass on the table, her robe flashed open and I caught a glimpse of her sweet DDs. I was disappointed that I didn't get a better view.
Without thinking, I said happily, "Have I ever told you that you have magnificent tits?"
I have no idea what came over me, and she had every right to freak out. But she didn't. Instead, she grinned wider and said, "You wanna see 'em?"
"Do I ever!"
Giggling, she peeled back her robe, and there she was, in all her titular glory. Kayly's breasts were really large for her age, but there was no sag at all yet. The nipples were smaller than I expected, and paler; they were maybe as big as a quarter, but tightened to firm, eraser-sized points. I could feel myself salivating as my shorts got tighter...but I didn't feel nervous or self conscious in the least. "Good enough to eat!" I proclaimed.
"Maybe later," she laughed. "I'm gonna go lay out in the sun before it gets too hot."
"Well, don't wear that yellow bikini...or you'll definitely get too hot. I will, anyhow."
"Tsk, tsk." She stood up, shrugging the rest of the way out of the robe, and I fixed my gaze on her neatly-trimmed bush. "You know what?" she said brightly. "I have no idea why I wear those damned things anyway. It's our property, and we have a fence, so why can't I sunbathe in the nude?"
With that she waltzed out the back door, her cute butt as white as a cottontail in comparison to the rest of her browned body. "You'll burn your ass!" I said.
"Not if you rub suntan oil on it," she shot back. Well, I know an invitation when I hear one, so I jumped up, grabbed the suntan lotion and followed, my erection tenting my shorts. She was settling down on her belly on the deck chair when I arrived; when she glanced at my obvious hardness, she just smiled.
Grinning and feeling good about life, I poured a generous dollop of lotion on each of her butt cheeks and started rubbing it in. That was fun, but what I was really interested in was the lightly furred mound in between. It seemed to glisten invitingly in the morning sunshine, so I reached out and trailed my finger along the lips. Kayly just went, "Mmmmm." So, feeling greatly daring but not at all hesitant, I thrust my forefinger into her pussy up to the second knuckle.
"Fuck, that feels good!" she said loudly.
"Ya think?" I started to finger-fuck my cute daughter with first one finger and then two; that was all she was big enough to handle at the moment, but I made up for it with great zeal and precision, and when I pressed my thumb to her clit she started rolling all over the place, saying all kinds of nasty things. Finally she reared up, all but sucked my hand inside her cunt, and screamed. No, seriously. I was afraid someone was going to call the cops or something because they thought I was murdering her.
