A serious younger sister and a free-spirited older sister. A record of a certain sister's 8 years from puberty chasing dreams to marriage seeking love. Eros and sensuality caused by the intersection of the older sister's consideration and the younger sister's bravery. Was it your sister who fell asleep? Was it my sister who was cuckolded? Lust that swings between family love and sister love. 4 hours long, I have never seen such a drama AV! !
