You go to your Step-mom, very upset with the size of your small dick. She is slightly alarmed at how small it is and confesses that she masturbates with a small dildo as a 'warm up' for her big dildo. She notices that you are aroused and might cum, so she has you go and cum in your room. Later, you find your Step-Mom moaning loudly while masturbating with a large dildo. She sees you and lets you watch; she also pulls out her 4-inch dildo, swapping back and forth between the large and small dildo, all while telling you that your small dick would still be satisfying. Now you are masturbating while watching Step-Mommy; she teases you by admitting that you are now a cuckold since you like watching her masturbate with the big dildo. She cums with the big dildo, acknowledging that she needs a big dick but assuring you that yours is big enough.
