In this H-content plan, we managed to get two close siblings - a sister and her brother - to participate! It turns out that the younger brother is still a virgin! So his older sister decides to teach him about sex... but she initially doesn't want to because there's a reward involved if he can just sit through a lecture on how to do it without actually doing anything! However, as time goes by, she starts enjoying herself more and more... even though they haven't done anything yet! Keep in mind that the recording contents may vary depending on the broadcast method used.
