Jodie had a head start, but I collected myself and went into the house not long after she did. I paused outside of Katie's door and could hear the two talking.
"Yeah, it was really big. I couldn't even take all of it at first!"
"Oh my god, I know! I had a lot of practice though. I stole one of the toys mom left. I've been using it to get ready."
"Wow, do you still have it?"
"Yeah, I'll be right back!"
I hid around the corner and heard Jodie run to her room then back to Katie's. When I stepped back around I noticed the door was slightly opened. Katie was wearing a sundress, but Jodie had swapped the overalls for a bra and panty combo that I didn't remember buying her.
"Whoa, that looks so real! You practiced with that?"
The object in question was a silicone model of a real dick. More specifically, it was a model of *my* dick, made for my ex-wife before she took off with her business partner.
Katie toyed with the object, as Jodie asked, "Want to try it out?"
"I'm still pretty warmed up from this morning. I think I could handle it."
Katie leaned forward and kissed her sister, only breaking off the kiss long enough for Jodie to pull the dress over her head. Jodie pushed her back against the bed, then traced a line of kisses across her chest, down her tummy, and to her well fucked cunt.
Katie parted her legs, giving her sister unrestricted access to her pussy. The let out a long moan as her sister's tongue had its first taste.
"Mmm, I can still taste daddy in you. Lovely. Your pussy always tastes so nice, Kitty Kat."
"Jo, you know all the right places to put that mouth of yours."
I watched as my middle daughter licked and slurped at her younger sister's pussy. Katie arched and moaned at her sister's skilled touch. My dick demanded I swing open the door and fuck these two senseless, but I fought the urge.
After what seemed like an eternity, Jodie lifted from her sister's pussy, her face covered in Katie's cum.
"Okay, Kat. Time for this monster." I realized as Katie did that the panties were a harness, and Jodie strapped the dildo to herself. Katie's eyes rolled back as Jodie pressed the head down into her slick hole, and inch after inch slowly disappeared into her cunt.
"Oh, God. Oh, Jo! It feels like daddy! Jo, you're stretching me out so good."
I watched as Jodie's round bottom slowly rose and fell, pushing her silicone toy into her sister. "Take it. Take all of it, you slutty little kitty."
"Oh, oh! Give it all to me. Fuck me hard. Fuck me like daddy did. Make me cum all over your cock!"
Jodie gripped her sister's hips and really drove into her. "Oh, yeah. I'm going to fuck this tight snatch until it's soaked in cum."
"Soak my cunt with your cum, daddy! Fill me up with your baaaaaabyyyyyyy…"
As she cried out, her orgasm shook the foundation of the house. Jodie only stopped pistoning into Katie after it subsided, then collapsed onto her sister in exhaustion, the faux penis still deep inside her.
I stepped away from the door, only to find my oldest daughter, Maxine, right behind me, peering through the door. She shushed me before I could make a sound. She pulled me down the hallway to her bedroom and closed the door.
She wore her typical outfit of a simple monochrome jacket over a shirt, matching knee length skirt, and round glasses. She gave most people the impression of a prudish librarian, but I knew the truth.
"So, did they do it?" She asked excitedly.
"Do what? Have sex? You saw them same as I did!"
"Obviously not that. They've been doing that for months. Did they follow their plans? Did you fuck them!?"
"Wha- Plans?" I stammered.
"Yeah, they both came to me, hinting around for advice, and I might have let slip that you are crazy horny after a workout, and that you're a sucker for a sob story. After that, it was just a matter of time."
"You set this up?" I asked.
She pulled at my shorts, dropping them to the ground and freeing my raging cock. "Set it up? Me? I just gave them a nudge in the right direction." She started stroking me as she continued. "I'm not super excited about sharing this with anyone, but I suppose it's only fair."
We peeled clothes off of each other as she continued. "Look at the bright side, daddy. We won't have to be so secretive any more. We can fuck any time we want now."
"Oh, you horny little minx. You're too damned smart. It's going to be my downfall." I leaned down to kiss her, but she pulled away with a grin.
She sat back and slowly crawled backwards up the bed, with me crawling towards her, my lips chasing hers for a kiss. She bumped against the headboard and our mouths meet, her soft lips and sweet tongue mingling with mine.
She broke the kiss after a few moments and pushed my shoulders down before she directed my face towards her warm crotch. I kissed her gently on her inner thighs as I worked myself inward.
Soon I reached my prize, with my tongue tasting the heaven of Maxine's juices. I licked and lapped at her folds, and though it was something I'd experienced many times, every taste seemed better than the last.
Her thighs squeezed my head as she gripped my hair and grinded her pussy on my face. Her cries were muffled to me, but she seemed to be making no attempt to conceal our lovemaking from her sisters this time.
"Oh, fuck, daddy! Right there! Oh my fucking god!" Her body spasmed as she came, drenching my face. Before she fully subsided, she had already pulled my face into her pussy again, and I licked and tasted it all over again. I kept her riding the edge until she tipped again, this time keeping my mouth locked onto her cunt so I could keep her riding the wave for as long as possible.
When she finally came down again, I started in again, but she pulled me away. Breathlessly, she told me, "Enough. Oh, wow. I need you, daddy. I need you inside of my cunt, daddy."
I sat and pulled her up, until we were seated, her legs over mine, and my hard cock between us like a flagpole. She kissed my face and licked her own juices from my lips. "Mmm, daddy. I taste good on you."
"Baby, you taste like heaven every time. Now I'm going to fuck your tight cunt until you can't think straight."
"Oh, daddy. That's going to take a lot of fucking. Are you sure and old timer like you can handle it after fucking both of my sisters in one morning?"
I scooped her up with my hands under butt, and held her pussy over my cock. "Oh, I think I can handle it, sweetie."
I lowered her down, slowly feeding my length into her soft and well lubricated hole. I could only envision her lips swallowing bit by bit of my cock, and it was almost enough on its own to send my seed bursting into my daughter's belly.
When she finally came to rest on my pelvis, my cock fully inside her, I released my grip on her butt and allowed my hands to roam the rest of her body. Her sexy narrow waist and wide hips, along with her ample breasts, were normally hidden away from the world by her conservative attire, but were laid bare for my eyes alone to appreciate.
"God, Maxine, you are so sexy."
She started rocking her hips, massaging my dick softly with her cunt. "Oh, daddy. Of course you'd say that I'm sexy. You're having sex with me. When is someone NOT sexy when you're having sex with them? Ahhhh!"
She cried out as I pulled her close to me. Her legs locked around my waist as I spin my legs over the edge of the bed and stood up. I carried her over to her oversized reading chair, laid her into it, and started fucking her with long, slow strokes.
I roughly pulled her face to mine and kissed her long and hard before I answered back. "Baby, you are the sexiest creature in existence. I love you and your sisters more than you can imagine, but you are the one that first seduced me. I love you and I love that you are all mine."
She rocked her body against mine, gently prompting me to go faster and harder. "Do you- Oh- do you mean that?"
"Of course, baby."
"What if I said what Kat said?"
I almost lost rhythm when I asked, quite eloquently, "What?"
She pulled me back into her cunt and answered, "When Jo was fucking Kat. Right at the end, she called Jo 'daddy' and asked to put a baby in her. Would you do that? For me?"
The sudden thought caused my dick to throb inside of my daughter's cunt. I picked up the pace, fucking her with vigor.
"Say it. Tell me what you want." I grunted in her ear.
"Fuck me, daddy. Fuck me hard. Fuck your daughter's pussy like only a daddy can."
I was pounding into her with everything I had.
"Fuck me, and keep fucking me. Fuck me until my belly swells up with your baby. Fill me up, daddy. Fiiiiiilllllll meeeeee uuuuuuu-ahhhhh!"
Her pussy thrashed against my cock, and I came in her, filling her with my incestuous spunk. I knew she was on birth control, at least for the time being, but fantasizing about her belly swelling with a child sent me into overdrive.
I fucked into her until my balls were completely empty and I'd pumped every drop of cum into her, then I kept fucking her until my dick could handle no more and my legs were about to give out.
I finally dropped to the floor, and as I looked up to Maxine's dangling legs, I saw the door slowly open. Jodie and Katie crept over to us and started licking and sucking our well fucked organs.
As they cleaned the spunk from our bodies, I could only drift off into a well earned afternoon nap.
