Your step-mom can't rest so she's up reading in the living room. You come out not realising your step-mom is still up. She asks if you're not feeling well to which you show her your hard on. Looks like you're growing up! She tells you not to be embarrassed by your hard on, every man gets them. Then to your surprise your step-mom shows you how to stroke your hard on to release all that tension and pressure. Then you'll be able to rest better
