28-year-old virgin Yoshiko Kimijima(not her real name) is a young lady who was raised in a strict household where she was not allowed to have sex until marriage. She accidentally lied to her fiance, whom she plans to marry next year, that she had had experience with men. In order to make that lie come true, she decided to lose her virginity by appearing in an adult video. It was Yoshiko's first time seeing or touching a penis, and she is so lewd that she gets wet just from a kiss. Then a penis penetrates her tight, wet pussy...
