Step-Mom goes into your room to wake you up for school and notices a bulge inside your pants. It's a pretty small one so she encourages you to jerk off to make it bigger, while she teases you with her big fat ass. She's had sex with you before so she knows how small your dick is, and even tho she's settled for that other times, now she won't accept anything under 12 centimeters, so you better stroke and grow that cock. 12 centimeters is still small but she has expectations that thinks you can fulfill. Anyway, you still can't reach that measurement and disappoint her like the microdick owner you are. This time she won't pretend she's having a good time to protect your feelings: you're not gonna fuck her with that useless thing! Ever again!
