She's thinking it would be nice if she could start making babies with her husband soon... Since it's a good opportunity, she wants to learn from the AV internal ejaculation pros how to have sex that will definitely result in a baby! She volunteers for real internal ejaculation. Forgetting about baby-making practice with the feeling of real intercourse for the first time? Going all out! She wears a karate gi over her naked body and even records a serious karate match! The contrast is cute~.
