La matrigna gigantessa riduce il suo ragazzo

StepMommy has a very fun plan for you tonight! She's shrunk you down to 1/1,000th her size for an evening, and you're going to be watching TV together. And you'll be resting in the best seat in the house - the front of StepMommy's thong. After some time watching TV, you notice the mountainous bulge you're resting on begin to twitch and grow - StepMommy's got something else on her mind tonight. You wonder what she's about to teach you about how your body works... But don't worry, StepMommy will always keep her boy safe.
