You are in the shower when you step-mom accidentally walks in on you, thinking it's your step-dad. She apologizes, but quickly becomes concerned when she notices something rather unusual. The size of your dick. Well, it's just really really small and she's worried there might be something wrong. But after she knows it's just how your small cock always looks, she begins to giggle and tease you. You stand there naked and embarrassed as your step-mother continues to laugh and humiliate your tiny size.
