Virgin's pussy is the best!! Innocent little sister's first time having sex, 4 hours. KTRA-672

My lovely and innocent little sister… Although she's very obedient now, I simply cannot bear the thought of her ever dating another man and developing a romantic relationship with him!! Before any other man's penis penetrates her, I must first enjoy her pure, innocent vagina!! I will gently, carefully, and then erotically teach her how to make love!! Opening her untouched, pink vagina and inserting my erect penis, the intense tightness almost made me faint!! Having forbidden sex with the best virgin sister, we will enjoy each other's bodies to the fullest for these four hours!!
