Elana Bunnz is your stepmom and you've shrunk down to 12" tall. Elana is ready to do her workout for the day, which consists of squats and some hip twerks. Luckily for you, she decides to do it on the chair you're currently sitting on. After a few squats, she feels something and realizes you just came on her ass. She scolds you, but realizes you have a gigantism fetish. She takes off her shorts and is wearing a thong.
This switches from POV to a few third-person shots. She notices you're still really hard, so she decides to give you a lap dance. Then, she rubs her ass on her stepson a few times. She gives you several ejaculation counts and you can't control yourself. After the last orgasm, you shrink down to 6" tall. She decides to put you in her cleavage to play with
for a while, then she puts you in her thong and masturbates with your help, and then leaves you there
