Plug Valerie's vagina with your large cock

From Create Your Own Story

You decide to make sure her womb is thoroughly filled by the time all the pills start their magic by keeping your large dick firmly rooted inside cum-stuffed vagina for at least 2 more hours.

While still firmly rooted inside your sister's wonderfully tight and cum-filled box, you reposition her so you're spooning her from behind, allowing you to comfortably keep your cock lodged inside her without putting more pressure on her stomach and forcing any more cum to squirt out.

In fact, now that you've had a time to breathe, you realise that your sister's cunt feels even tighter, and that not a single drop of cum has managed to escape since you decided to plug her filled pussy which also feels tighter. You even notice that the barrier when you hilted yourself was gone, your cockhead seems to have actually pushed past your sister's cervix! With some certainty, it appears your demonic powers have, with the act of impregnating your sister and the sheer perversion of wanting to plug her with cum after giving her all those pills, actually increased the size of your genitals somewhat.

With a quick check, you also confirm your balls have grown, now the size of large apples and churning with even more potent seed.

Unsurprisingly, your enhanced assets now make it even more irresistible to remain stationary inside your sister's tight pussy so after only a few minutes, you're pumping your enhanced rod with the tip even inside her overstuffed womb, while you squeeze and play with her soft, soon-to-be milk filled breasts.

Your thrusts quickly increase in pace as Valerie's tight, soaking pussy begins moulding to your new size wonderfully, her orgasms coming even faster and harder than they did previously as your huge demon-enhanced shaft pleasures her like no mortal's would be able to, making her eyes roll into the back of her head as her mind just becomes blank with the obscene pleasure she's feeling.

The thought of having your own sister swollen with over a dozen of your incestuous offspring then continuing to impregnate her again and again like she asked soon brings you to an eruption of hot, thicker, immensely potent jizz delivered straight inside Valerie's swollen uterus, almost causing you to cry out in mind blowing pleasure as your improved testicles pump out gallons of cum over a full few minutes of orgasmic bliss.

You rub Valerie's now obscenely distended belly as your monstrous cum flow begins to slow, she looks like she's already about to give birth a couple of the many babies already developing inside her young womb.

Thankfully, your influence over the past few weeks has made Valerie's body elastic enough to easily accommodate even your large organ, the monumental loads you'll deliver and even pregnancies that'll stretch her womb beyond what a regular human could survive. She's so broken, submissive and compliant to you by now that you're sure she'd do anything you wanted of her, no matter the morality of it, she's yours and Brandon is no better, you're sure he'd be as unable to resist continuing his deplorable acts, he'd always been attracted to his hot sister anyway.

You're already looking forwards to the delicious results of your unholy union, and all the delicious results and other possibilities you might explore with your enhanced package as your cum thoroughly coats and fills your sister's eggs. You decide to continue using your demonic powers to make sure Valerie remains healthy and fertile. While you were at it, you could even alter the offspring as they grew to suit your perversions... or you could just leave her be and see how far you can push her till she just pops if you were feeling especially cruel. Or you could leave and introduce some other hot girls to your incredible dick. So, do you:
