Giant step-mommy loves to grow for you

Sstepmom is looking for you when she finds you on the floor. she smiles and comments on how tiny you are... or is it just stepmom that has grown non-stop recently? She continues to tease you with her huge boobs, belly, ass, and thighs until she picks you up and gives you giant kisses. You deny that you like it when stepmom grows for you, so she makes a deal with you: "If I can make you cum in under a minute, I'll stop growing." This is a custom.
