Stepson's Endurance Training

Samuel Passion has recently entered a relationship with a woman but is struggling with ejaculating too early due to his lack of experience. He confides in his stepmother, Diana Delight, who suggests overcoming this issue by practicing self-control through 'endurance training'. Though hesitant at first, Samuel agrees to let Diana assist him in this training.

Diana starts by stimulating Samuel's genitals without getting him too stimulated initially. Gradually, she pushes his limits by stopping whenever he nears climax. Impressed by Samuel's progress, she proceeds to perform oral sex on him to further challenge his endurance.

Desiring to take his training to the next level, Diana escalates the experience by engaging in sexual intercourse with him to truly assess his newfound stamina.
