Perverted StepSon: Shrunk and Punished

You have been masturbating over your Step-Mommy for a while now, and when jerking off over her used panties got boring you decide to peep on her and your Step-Dad having some "alone time". But when Step-Mommy sees you in the corner of her eye she thinks it's time to punish you for your perverted antics. Perving on anyone is wrong let alone your Step-Parents! Step-Mommy comes up with the genius idea to expose you to the taboo, in your tiny new form so that you associate these disgusting taboo thoughts with being tiny, pathetic and vulnerable.
Blowing her special shrinking smoke up your nose you have no choice but to inhale, waking up barely 1cm tall. You try and run away, but your little legs can only get you so far before Step-Mommy catches up with you. Now seeing as you ruined her orgasm with your Step-Father, you need to finish the job. You know it's wrong to do these things with your Step-Mom - especially while your Step-Dad watches but what choice do you have? You flick your tiny tongue up and down her clit (secretly loving it), and it's not long before she reaches climax. Now it's Step-Daddy's turn, and you're going to stare up at his big Step-Daddy dick as Step-Mommy sucks and spits all over his cock, covering you in the process. Hoping he will quickly blow his load inside of her mouth so this can be over and done with Step-Mommy wants to make the most of this very taboo threesome - and having her own personal clit licker while she gets fucked. You watch in horror, attached to your Step-Mommy's clit and Step-Daddy pounds her hard and fast. But when he finally explodes inside of her you unfortunately get caught in the crossfire, submerging your pathetic existence in his seeds of doom.
