Features a lot of incest breeding. Like, seriously, you've been warned.

I wake up to a familiar sensation. You, again using my sleeping body in the early morning. I'm used to your prefered method of getting rid of your morning wood, and I can't say I mind it very much. You see me open my eyes and plant a kiss on my lips. I feel your naked body pressed against mine, penetrating my pussy.
"Good morning sister"
"Good morning little brother"

Today is a big day. Our daughter is turning 18. This is the day of her initiation. We've been preparing, and we've been both looking forward to it. I suppose it's only natural we'd feel extra horny today.
"Can't wait to give Claire her first dick."
"I know my love," I reply. "I can't wait to have her pussy either."
"I dreamed about impregnating her last night."
"I bet you did, you little pervert. But you can't. That will be her little brother's privilege when he comes of age."
"I know, I know, I guess I'll have to impregnate you instead."
"Oh, promises, promises..."
We exchange a passionate kiss, and sure enough your cock twitches to deliver a load of cum in my womb.
"Come on, we have to prepare now."

I get out of bed, all naked of course, a drip of cum flowing down my leg. You follow me closely into the bathroom. The shower takes longer than it should, as usual, all because you can't keep your hands off me. It takes us a full hour to get ready. Claire, our daughter, is already waiting in her room. Nathan, our son, is not home today. He is still too young to partake, and we sent him away to avoid any temptation.

Claire is the spitting image of her mother, just 20 years younger. Same brunette hair, same wide hips, same build. The only major difference is that her attributes haven't been enhanced by motherhood yet. But that day will come.

She wears the white sheer dress I picked for her big day. We've talked at length about what would happen. You take place in the corner of Claire's room, on a chair you brought with you. This first part you can only watch. You asked me why it had to be me first. And I answered that it took nine months of my life to make our daughter. Her first time is mine, that's only fair.

All that time spent dressing up only to peel our clothes off in a matter of minutes. I give her a sweet embrace, just so I can feel her naked body against mine. Her warmth feels familiar, like a part of me almost. I let my hands wander around her curves, and she does the same.

You watch intently as our lips touch and our tongues intertwine for the very first time. I make that kiss last forever. I savor every moment of it, the taste of her lips, the smell of her scent, the touch of her skin. I commit all that to memory, because this is the only first kiss I'll ever get with my little girl.

"I love you mom," she says when our kiss ends.
"I love you my little princess. Are you ready?"

She nods nervously. I take her hand and lay her down on the bed, then climb on top of her. You feel your pants get tighter as you watch your sister and your daughter make out with such passion. I cover her body with kisses. Her neck, her breasts, her nipples, her belly, her legs, all the way down to her feet. Then I kiss my way back up, hoping from leg to leg until I reach her thighs. Then, very slowly, millimetre by millimetre, I kiss her left thigh. She moans mommy's name in pleasure.

Finally, I reach her pink, hairy pussy. She places a hand on top of my head, and the other on her breasts. I give a peck to her clit. She lets out a soft moan. I engulf it with my mouth and put some tongue on it, as if I'm making out with her clitoris. She purrs as I feel her hand tense up on my head. I keep at it, caressing her labia with my index finger. "Oh mommy," she exclaims. I can feel her juices are starting to come out. It's time for mommy to kiss those pussy lips. I rub my tongue over and push it inside. The taste is a bit sour but the feeling so sweet. With my thumb, I tickle her clit. She grips her hand on and pulls on my hair as the pleasure becomes more and more intense. Her breath gets shallower, her moans louder. "Mommy I..."

I feel liquid jet inside my mouth. Her body contracts and convulses. Her moans are incoherent and fill the room. Claire just had her first orgasm, and you loved watching every second of it. After she’s come down, I look at you and ask you to go get my toy. You know the one I'm talking about.

"Will you teach me to do that, mommy?" our daughter asks.
"Of course. But first, there is something mommy has to do."

You come back in the room with my strapon and a bottle of lube. I give Claire more kisses before I decide to slide it on.

The dildo is bright pink, slightly curved, shaped like a simplified version of a real penis. It's slightly smaller than you, you notice. I drop some lube on my fingers, and apply it in her vagina. Her body writhe as she's still very sensitive from her very first orgasm. I smear some more lube on the dildo, and get myself in position.

"Oh, mommy," she moans once more as the tip of my dick starts penetrating her. I start thrusting in and out like that, with just the tip. "Tell me when it hurts, okay darling?" I say, and she nods back. I move myself in the missionary position, and start thrusting again, this time pushing deeper with every stroke.

"Mommy it hurts," she grunts. "But don't stop." I keep going slowly until she lets out a yelp of pain as her hymen breaks. You wish you were in my place right at this moment, but we agreed a long time ago Claire's virginity was her mother’s privilege.

I take the dildo out and cuddle on top of her. I want to give her mind some time to process the pain and excitement. "I'm ready for more mommy," she says after a few minutes. I give her a big kiss, and insert the dildo right back. This time, it glides unimpeded. I pick up the pace and push further than before. "You feel so good mommy." The strapon rubs on my clit as I thrust. My pussy is getting soaking wet from the stimulation and the sheer excitement.

I look at you, you're still stroking on the chair. I give you a knowing look, and you get up. I pause my thrust for a moment as you climb in bed behind me. "What's going on?" Claire asks, but I tell her not to worry. I feel your hard cock press against my labia. And as I thrust out of Claire, I impale myself on you.

I fuck her while you fuck me. When my dildo penetrates her in, your cock slips out of my vagina. When my dildo moves out of her, your cock plunges back in. It's a perfect motion. "I'm cumming," you grunt after a dozen minutes of this exercise, and I push back on you with everything I've got. You drop your load deep inside my womb. You take a pill so you can stay hard, but with your balls now empty there's no risk of an accident with our daughter.

I take the strapon off and come lay next to Claire. Her pussy is exposed to you. You touch her with your finger and can feel she's still quite sensitive. Her pussy is well lubricated by now, from the lube and her own juices.

"Do you want daddy now?"
"Yes. Please daddy, I want to be a woman," she pleads to you.

You rub the tip of your cock between her labia. Laying on my side next to her, I embrace her and fondle her to enhance her pleasure. You insert the head, and she moans loudly. “Ah daddy!” You insert yourself further and start thrusting. You go at it slow, you want it to last. With your left hand, you start massaging her clit, while you send your other hand to finger my still wet pussy.

You make mother and sister moan in unisson. Your pelvis bottoms out with every stroke. Claire writhe in my arms. You’ve waited years for this, and it was worth every second of it. Her pussy is tight, so tight, tighter than mine. It grips around your cock even tighter when she quivers with pleasure.

“Oh baby girl, you make daddy feel so good,” you grunt. She moans mommy and daddy. I whisper in her ear “you’re doing great my love, you’re a woman now.”

Halfway through, you grab her hands and pull her up. We shift over. I’m on my back now, she’s on all fours on top of me. You’re still behind her, fucking her tight pussy. You go faster, encouraged by the slapping sound of your body against her cheeks. I’m wrapping one arm around her neck to make out with her, while another goes to caress her clitoris.

Our breasts are rubbing together, our nipples occasionally collide. “Can I lick your nipples mommy?” Of course she can. You watch me shimmy higher to give her easier access. She suckles on my tits, like she did when she was a baby. But this time it’s not for milk, this time it’s sexual. And then of course she asks that I return the favor, so I shimmy down to get access to her lovely breasts and suckle on them.

I still have my face full of titties when she comes, squirting all over me and the bed. Her pussy contracts violently, pressing on your cock like never before. It’s all you can take. Still inside her newly-deflowered pussy, your cock twitches again to deliver another load of cum.

Claire falls down on me, her legs and arms are too weak from the orgasm to stand. I look at you straight in the eyes.
“Did you come in her,” I ask.
“Yes. I know we said I shouldn’t, but I couldn’t help it. Are you mad?”
You see I’m not.
“No. I figured this would happen. That’s why I put her on the pill preemptively.”
“Always two steps ahead, are you?”
“Always,” I say with a wink.

We all get out of bed, and take a big shower together. It’s a tight fit, but we make it work. Claire is the centre of attention. We lather her with soap together, rub her body, kiss her. Then she washes my back while I wash yours.

While we’re drying ourselves off, Claire asks if I’ll teach her to give a blowjob, and we both watch your cock grow hard. We have a good laugh the three of us, and I tell her I will, after lunch.

We put on our Sunday best and go out for lunch at a nice restaurant. We both manage to refrain ourselves from touching our daughter in public. We know people aren’t ready to accept our love. She has her first taste of wine since she’s old enough now. We just have a lovely time, looking forward to an afternoon of debauchery together.
