You make Natalie your little sissy sister

Susan continues doing her good work and you feel the pants barrier that separated you from Natalie’s crotch slide away. You can smell her pussy, it’s calling you. You pull your hips back and slide your erection between her legs nestling it between her wet folds. You rock your hips back and forth giving her a taste of things to cum. You feel a shudder run through her body and see the flush spreading across her cheeks. With a moan you peel yourself off of the woman to watch her glow. Natalie is stark naked, her petite body is blushing under your ministrations. She pants softly her tongue hanging out. Her lust glazed eyes are focused on you, she looks ****. Susan makes a suggestion “Take her to her bed.” You reach out and take Natalie’s hand leading the woman through her own house she meekly follows. You smile knowing she needs you just as much as you need her.

You lay her down on her back across the side of her bed and lift her ankles to your shoulders. You rest your searing erection on her mons and look her in the eyes “Natalie, I’m going to infect you.” She trembles and ever so slightly nods. You slide your hard cock deep into her sopping pussy. It wraps around you squeezing, caressing, begging. Natalie starts to moan as soon as you start moving. Indistinct soft feminine sounds that only urge you to fuck her harder. And you do. Your dick swells filling her up utterly. The heat and lubricated friction is all you feel as you pump away into her. Then Susan grabs your balls pinching them between her nails and everything contracts. One instant you’re on the edge of orgasm, the next instant you’re pumping Natalie’s sweet pussy full of your infectious cum. Your dick throbs powerfully each motion shooting more of your cum into her sweet tight pussy until she overflows. Your white pearls are flowing down her pussy lips and ass, but your dick continues to throb hard pumping more of your infectious semen into her. A small puddle collects on the bed under her hips. You pull out slowly enjoying the tight pressure of her pussy one last time.

You look at your handiwork. Natalie is **** on the bed, she must have passed out at some point. Her pussy is slowly leaking some of your massive load. A small sense of pride swells within you as you watch her seep undeniable proof that she is yours. Your grin swells larger as you watch the gentle rise and fall of her chest, after taking a load like that there’s no way she isn’t infected. As if you needed any proof you see her breasts start to grow. Of course, it’d be a shame to let your sweet sticky load go to waste. You lean down and start to lick your cum out of her pussy savoring the taste of your union. You close your eyes and dive into her wetness. Gradually you transition from eating pussy to sucking dick as the seed you planted in her grows. Supple thighs wrap around your head and you feel more than hear her moans as she awakens to oral pleasure. She throbs in your throat, your mouth waters, and you cheeks hollow as you suck on her hungrily. You’re rewarded when she pours her very first infectious load straight down your throat. You cradle her balls in one hand squeezing them gently as you wring her dick with the other. You milk her for every last drop. The tingling of her cum on your tongue makes your brain tingle too and you greedily swallow it down.

Natalie is fucking stacked. Her tanned legs grow almost indecently thick at the thighs supporting her big bubble butt and her swinging cock. A thin waist frames her toned abs, but her tits steal the show. The perfect twin mounds look too big for her body, if it weren’t for her impressive ass they’d surely overbalance her. The twins hang off her chest firm and round inviting and demanding to be touched.
