I'm your step-mom, and I'm regretting taking you in! I go to work all day while you do nothing? That's unacceptable! I won't tolerate having a worthless, lazy step-son!
I'm in the middle of a long, nagging, bitchy rant when the tea you gave me starts to kick in. At first it's just a headache, but then I feel it ... the growth. The transformation. Suddenly, I spread my legs, and right there where my pussy should be ... is a huge futa girl dick!!!!
What did you do to me?!?! But it's not just my genitals that have transformed. I can't stop touching my big futanari girl cock. And the more I touch it, the more I feel my thoughts just ... disappearing. I'm sorry, step-son! I can't resist! I jerk off my cock, harder, faster, eyes crossing and tongue lolling out. I try to stop the transformation from happening but I'm just not strong enough. I give in ... and cum. A huge load erupts from my step-mommy futa dick. I just cummed out my brains! I can't even speak anymore, except to say ... I NEED MORE!
I've totally lost control! With unfocused eyes, I suck your (smaller) cock while stroking my own. You jizz in my mouth. It drips past my lips while I stroke myself to another orgasm. The rest of my brains are cummed out with it ... and the transformation is complete! You stare at me, your step-mommy, naked, covered in jizz (mine and yours), and it's obvious. I'm totally braindead! I've transformed into a mindless, braindead, free use futa fuck doll! I'm officially the step-mommy of your
