creative freedom: this fictional piece includes a little cum chamber right before the cervix that, if breached, holds the semen to secure Insemination

This scene was written for another reddit-or. Enjoy, darling.

—

Four weeks ago, you gave birth to my son. Four weeks to the day… and you wanted to have sex again. Careful. Slow. Plain old missionary position. Your eyes on mine. Don’t worry, I’m taking it easy, baby.

The very first time, your chamber was sealed shut, protecting your body from getting pregnant. Even when I did come inside you, there was no way you'd get knocked up. That last inch inside you wasn't possible to penetrate, your cervix protected from my cock, my sperm. Week six, you started to do your kegel exercises on me. Straddling me, on top, clenching your pussy, practicing... it always took some time until you could take me in again, your folds slowly stretching to accommodate my girth.

Eleven weeks in though, we are in bed, and your hand starts to wander. Laying on my back, one arm tucked behind my head, you rub my stomach and then slide your hand lower...over my waistband, to the curve of my cock. As soon as I blink my eyes open, you lie back, nightdress up, legs falling open. An invitation.

Don't mind if I do...

It's late at night. Our son is asleep, but he'll wake up in an hour or two, demanding to be fed. I climb on top of you, staying under the covers, and graze my nose alongside yours. I rest my bodyweight on you and start to roll my hips. Your lips fall open with a sigh. Eyes closed, "oh..yes," you whisper as I start to grind against you. Like I'm fucking you... I am getting hard from watching your reaction. Your hands on my shoulders, legs spread open. I roll my hips...over and over again, against your bare pussy with my briefs still on. You're slowly but surely getting the fabric wet.

Your soft breasts against my chest. Your soft breath. Your sweet, feminine scent.

I pause, reach down, and pull my briefs down over my cock. You don't look down. You look at me. Like I'm the center of your world. Giving you babies. Giving you an easy, beautiful life. I brush my cockhead between your folds, up and down, getting it slick. You adjust the position of your hips, tilt them up, giving me better access. And then, I rest my tip between your folds and place my hand next to your pillow Ready? I ask with my eyes.

You hold your breath, knees up, lifting the blanket as soon as I push in. You let your head fall back into the pillow, eyes closed, lips pressed together. It's still a tight fit. It'll get better with time. I don't stop adding pressure. A fine line between going too fast and just the right pace. And then, your lips part, you pant a couple of times and stare up at me. In.

I pause with my cockhead stretching your entrance. That part that is so damn tight, clenching around my girth, making you curl your toes. I smile that cheeky smile of mine, mischief glinting in my eyes. These days you just want to practice. Sometimes you orgasm, sometimes you don't.

I start to move, press forward, deeper-deeper-deeper until you puff out breaths and your nails dig into my skin. Easy there, big guy. I pull back a little, then pump in again. One more...and another..getting my dick wet. Halfway in, almost all the way out. Your walls are giving way, opening up at every thrust. With my forearms next to your pillow, I drive in again and again. I can feel my glutes clench as I push forward. You lift your feet off the mattress, knees pointing at the headboard. I love how tight you are...but I also loved it when I could just slide in all the way when you were pregnant with my son.

You hold on to me, barely making any sound as I warm your pussy up. Again and again. "Yes..." you whisper the word. Like I am doing the right thing. Nice and slow. In and out until I finally push against the seal of your chamber. It makes you whimper, eyes screw shut. When I roll my hips forward again, I can feel that the seal isn't as tightly shut as before... That's promising. I add more pressure, testing its flexibility and making you shudder and whimper loudly.

"Shh shh shh.." I pull back. I'm gonna be gentle, don't worry.

I stay right at the seal, intrigued and curious of how much I can push it this time. I stay deep inside you, as deep as I can at this point, and just pump against it over and over again. Nudging it. It's definitely softer. I wonder if you know... how soft. Your pussy is so wet that you're soaking all of my shaft and when I press it, really push it, my carefully cropped pubes too. I get into a steady rhythm. Nothing fancy. Just sliding in and out of you, the sound of your pussy loud between us. So wet.

You close your eyes, seemingly trying to relax. I watch you without stopping. I keep going. Steadily nudging your chamber, continuously adding pressure. I can feel it soften. I can feel it give way. Like I am seducing it to open up through that steady fucking motion. I don't thrust in hard, I don't make the bed thump against the wall. I know what I want. I want to get back inside that little piece of heaven...

I tilt my hips forward, and then I feel it, how your seal is starting to kiss the tip of my cock when I pull back. Proper soft now. I am on a mission... I do it again. Your eyes fly open like you know what I am setting out to do now. "OhmyGodyes," you exhale the words in one go, all quiet, as if you don't want to wake the baby next door. The next time I thrust in, your seal gives way a little more, stretching inward, toward your cervix. I can feel it open.

Again.

My forehead against your shoulder.

Again.

Harder this time. Thrusting in harder, faster. My breath comes out shorter, so does yours. "Give me another baby, please," you whisper, so sweetly. And that, that does it. I grunt, primal and low, and tense my entire body when I thrust forward with more force. Not yet. Your seal sucks on my tip when I pull back and push back in. "Please, it would make me so happy..." I groan, my mind suddenly blanking out and the tension in my body overtaking any movement I could make. I grab onto the headboard, leveraging the strength of my arms to give you that final thrust. You cry out as soon as it happens, your chamber pops open the same time I shoot my load inside you. You can feel the force of it, hitting your cervix over and over again. I tremble, gasp, moan as my balls contract to pump your chamber full. I stay inside it, feel the seal trying to close, clenching right underneath my frenulum.

The muscles of my arms tense as I hold onto the headboard and then finally let go, dropping back onto my elbows. I bury my cock deep into you, as deep as I can. Shifting my hips to make sure there's no way deeper. Your lips are parted in a silent cry. You shake underneath me, thighs twitching under the blanket. Your entire pussy pulses, contracts, trying to close around my dick, possibly trying to push me out. But no. I'm here to stay.

I move back slowly, letting my cock slip out of your chamber. It seals shut immediately. I can feel it at the tip of my cock, closing, full of sperm again. Mission accomplished...
