A boy who was still a virgin talked to a busty older sister with G-cup breasts or larger about his troubles, because he was too quick to ejaculate and couldn't even reach the point of insertion before ejaculating! He finally got to touch his penis while listening to his troubles. From paizuri to fellatio... I thought he would finally graduate from being a virgin, but he ejaculated again! But don't worry. The kind busty older sister still inserted her erect penis into her vagina! She thoroughly took care of his first experience.
