There is a knock at the bedroom door. "Time to get up, girls, Mommy has breakfast ready."
It's Daddy reminding them that they are all going sailing today. Venus stirs first and calls out, "Okay Daddy, we'll be right down."
She looks over at Delilah, sees her slumbering sister, not the lover that so excited her last night.
"Delilah, come on, we've got to get up."
Delilah rolls over on her side facing Venus, one enormous mammary atop the other, and groggily says, "Okay, give me a minute."
The sight of her naked bosom gives Venus an instant thrill. Visions of last night pop back into her head.
A little distractedly, she mutters, "That was our loving Daddy, we shouldn't keep him waiting."
After a pause, Delilah, still half asleep, muses, "Is he as loving of you as he is of me?"
Suspiciously, Venus asks, "In what way do you mean?"
"Never mind," Delilah sighs.
"No really."
"Well, for example, does he pet your kitty?" Delilah asks, with a tinge of sarcasm.
"Kitty?"
"Yeah, your kitty; your pussy, your cunt. Does he play with it, does he lick your clit and get you off? Does he let you suck his cock?"
Venus is shocked, she doesn't know how to respond. She asks, "Has Daddy done those things with you?"
"Yes he has, sweetie, and I loved it."
Now she is a little shaken and a little embarrassed. She has honored her pact with Daddy for nearly two years now. She doesn't want anyone, especially Mommy, to know. And she doesn't want her sex with Daddy to end. Telling Delilah about it could jeopardize all of that.
"But he doesn't do it with you anymore?" she asks.
"Not since college."
"Do you miss it?"
"Only a little," Delilah allows, but not about to let Venus escape, she presses, "Now, come on, hasn't he ever pressed his hardening cock to you when you sit on his lap?"
Venus has a very clear memory of exactly that. She's starting to get the picture that Daddy gets around. Maybe he's not just HER Daddy.
She eases into it with, "Well, he has fingered me a few times, yes."
"Did you like it?" Delilah asks.
"Yes."
Pressing further, "What else has he done?"
Flustered, Venus finally lets fly, "He's gotten me off dozens of times. I've sucked his cock until he cums in my mouth. We've been lovers since my 18th birthday. There, are you happy now?"
"My, my, little sister, you have been getting your cookies, haven't you? I had no idea. Maybe we should have a little fun with Daddy this weekend. Let him know his daughters have learned a lot since he started with us."
"What do you mean?" Venus asks, "what do you have in mind?"
"I don't know yet, let's see how the day goes. For now, we'd better get downstairs before they send up a posse."
She winks, then pops out of bed, still nude of course. Venus is thinking, "What a body, no wonder Daddy couldn't help himself."
Down at breakfast all is well. Mommy has prepared stacks and stacks of her decadent blueberry pancakes. They dig in. It's like they're kids again.
It's not long before they are off to the lake. The morning is spectacular, bright sun and a light breeze. A perfect day for sailing.
Once on their boat, it's like they've escaped to their own world. Daddy, with his skipper hat on, the girls in their bikinis lying on the deck to either side of the mast, and Mommy below fixing whatever she's fixing. It's like turning the clock back ten years when they would spend so many summer weekends on the boat. Lake Michigan is practically an ocean, so sailing out of sight of land one can easily imagine being on the high seas. Which is what they did as kids; helping Daddy with the rigging, taking turns at the helm.
Being older now, it's more about relaxing and soaking up the sun. Delilah's wheels are turning though. She'd like to surprise Daddy. She would like to give him a special thrill on the "high seas", but how to do it with Mommy along? That's the hard part.
From Daddy's vantage point at the helm, he sees his two daughters laid out as if they were on a beach. They are on their stomachs, their heads toward the bow, so he is looking along the full expanse of their smooth legs from the backs of sun tanned ankles up to that wonderful fold where they meet up with their rumps. Venus's little bum is very tight, 'buns of steel'. Delilah's is large and shapely. Each has much to offer, as far as he's concerned. The thought of having his way with the two of them right here in the sun crosses his depraved little mind.
Delilah spreads her legs slightly to be sure Daddy can see all she has to offer. She bends her leg at the knee to move one foot in a long slow arc, then the other. She flexes her ankles periodically so he can see her calves contract and relax. Just to be sure she has Daddy's attention, she raises up on her elbows and presses her pelvis into the deck to flex her ass cheeks. She looks back over her shoulder to see if he is noticing her antics and picking up her signals. He's in sunglasses looking straight ahead, so she can't be sure.
She decides to rotate around so she is looking directly at him. Her massive boobs bobble as she changes position. There is no way he could be missing any of this! But he is doing a perfect deadpan.
He knows Delilah like a book. Pay her no heed and she will knock herself out to get your attention. She's had it from men all her life and never stops craving it. She is the polar opposite of Venus. Venus mistakenly believes that men don't find her attractive; which is exactly why she is so irresistible.
