Originally commissioned as a custom - no names are used.
You arrive back at your StepMom's house during spring break, you have had this week long intense training session planned for a while which is designed to help you to hold an edge for as long as possible. There's only two rules: you have to do as StepMommy says and you are NOT allowed to cum. As a Man, it's important that you learn to have full control over your mind, body but most importantly your small penis. Once StepMommy is fully satisfied that you have passed this very important life lesson, then you are allowed to leave.
*With themes of SPH, cum denial, edging, JOI, pee desperation
