My two daughters, Kari and Delaney, had always been close from the time they were little girls, and though they did have disagreements at times like most sisters do, for the most part, they were inseparable.
My ex-wife, Carolyn, and I had been quite young when the girls came along; we were eighteen when Kari Marie had been born; Delaney Anne came along three years later, six months after Carolyn and I had gotten married.
Even now that Delaney was eighteen and a high school senior, and Kari a junior in college at twenty one, they still did everything together when Kari was home on school breaks, and as I would eventually find out, everything meant that--EVERYTHING.
Of course, I suspected something was going on from the time my wife had caught the girls in bed together.
When she had told me about the two girls in bed together while she turned the heat up a little, I had to wonder if Kari and Delaney had indeed been creating a little heat of their own even back then, but I never voiced my suspicions to Carolyn.
Years later, our marriage had ended when Carolyn had met a younger guy at work and began an affair with him before they'd gotten married only weeks after our divorce was final.
Of course, I got the girls when her new husband wasn't interested in being an instant dad, and truth be told, Kari and Delaney had no use for him either.
Meanwhile, I had dated (and slept with) a few women after Carolyn and I were divorced, but for some reason, I hadn't found any of the relationships I'd had very satisfying.
Then again, I could be a pretty horny guy, and even my now ex-wife couldn't keep up in bed either.
Most nights after our divorce, and then me giving up on dating (even for only a casual fuck), were spent with me alone in bed with my hand and a wad of Kleenex.
While Carolyn may have been a bit more reserved when it came to the subject of sex, I was more open minded about it, and both girls knew they could come to me to discuss their love lives.
It had been during one of these talks that I knew Kari was bisexual.
A beautiful brunette like her mother had been in her day, Kari was five feet six, with a well-built, toned body, full tits, and a bit of bounce in her ass, and with both her sexy looks and outgoing personality, she had had no trouble getting guys from the time she reached junior high.
Though she did have a boyfriend, Kari also confessed to me that she had also had slept with women from time to time; sometimes she just needed to give or get a good pussy eating rather than have a hard dick.
This revelation had gotten me to thinking.....was she having sex with her own sister too?
They did seem a little close over the years, and then there was the one incident of them in bed together, naked under the blankets.
No, of course not, I had thought. Only a pervert would think of such a thing.
While Kari had been sexy and outgoing, Delaney was shy, and had only had a few boyfriends over the years, none which really lasted.
She was a redhead like her grandmother and quite pretty, but at only five feet two, she was of average build aside of also having large breasts like her mother and sister.
While Kari dressed to show off her tits and hot body, Delaney was self-conscious about them and hid her own body under baggy clothes.
Still, as Delaney got older, I found myself strangely attracted to her more than I was to Kari, even if I loved both of them equally.
Maybe it was the mystery of what was really under those loose clothes she wore.
Nevertheless, I knew it was wrong to see either of them in a sexual way; they were my daughters, after all, and I spent many years burying those feelings.
Men just didn't fuck their daughters, at least that was what I told myself at the time.
At least until one afternoon when I had come in from work.
There was a noise coming from upstairs, some soft moans as if someone was hurt.
Kari had been home during her semester break, and I wonder if something had happened to her, so I went upstairs immediately to check.
Her bedroom door had been ajar, and she wasn't hurt at all; I had gotten an eyeful instead of both daughters naked on the bed.
Delaney was on her back, her legs spread wide as Kari's head was buried between them eating out her sister's pussy while Delaney moaned and writhed in pleasure.
As I watched my older daughter lick and suck the cunt of my younger child, felt my own cock growing hard.
I always wondered what it was like to see two women do each other, and now I was getting a show.
Delaney pushed her sister's head off her pussy, then positioned herself until they were into the 69 position.
Both girls' faces were buried in the pussy of the other until they exploded into mutual orgasms as one of Kari's fingers slipped into Delaney's ass and two of Delaney's fingers disappeared into Kari's wet slit.
Once they had both cum, Delaney climbed off of Kari, collapsing back onto the bed, both of them engaging in a passionate kiss while fondling each other's bodies.
I felt my cock about to rip out of my pants and needed to go somewhere to get myself off, and quick.
As I went to make an escape to my own bedroom for a major jacking off, I had bumped a table in the hallway, causing Kari to call out.
"Hello? Who's there?"
"Kari?" I called out, trying not to let on that I had seen their little sexual escapade. "It's just me, baby."
"Oh, all right, Dad. Del's here too. We're fine."
They certainly were, I thought. Fine and made me horny as hell.
By the time I'd gotten back to her room, she and Delaney were under the covers.
"You girls cold?" I asked, trying to be casual. "I can turn up the heat a little. I know these old houses---"
"Dad," she laughed. "You don't have to put on an act."
"What?"
Delaney, not the shy girl now, had eyed my engorged crotch.
"You saw us fuck, didn't you?" she asked.
I felt my face get hot. "Um.....yes. But I--"
"You know, Dad, I always thought you were hot," Kari smiled mischievously at me while tossing back the covers, showing both hers and Delaney's full nudity yet again. "It pissed me off that Mom didn't appreciate such a sexy man, and if you hadn't been my dad...."
"You actually thought about--" I began, not believing my ears.
"We both have," Delaney said, suddenly shy again.
"You girls know this is wrong," I said. "I'm your dad, for God's sake."
"So is Delaney and I fucking," Kari pointed out. "But we've been doing this for years. Neither of us have had much luck of finding a guy--or a woman--that really gets us off except each other."
By now, I was sitting on the bed between my two naked girls, looking over at Delaney. "You like women?"
Delaney nodded. "I'm bi too, though I haven't had as much good luck in the men department as Kari has."
Kari then rubbed my crotch. "Maybe if Daddy wants to, your luck could change, Sis."
She then took Delaney's hand and guided it to the tent between my legs. "Feel that, Del."
A groan escaped my lips as two separate hands rubbed my bulge; the next thing I knew, Delaney was pulling off my T-shirt as Kari unzipped my pants, leaving me as naked as both of them were.
Kari then shoved me back, getting on side of me while Delaney was on the other, both girls engaging in another passionate kiss before each began kissing and sliding their hands down my body, teasing me, until Kari's hand began stroking my cock while Delaney's rubbed my balls.
I couldn't even remember the last time I'd gotten a good fuck from ONE woman, much less two, and something told me this was going to be a night I wouldn't forget.
