In the hospital life where I couldn't move my hand due to an injury and was forced to abstain from masturbation, I couldn't hold back and asked my beautiful and busty sister-in-law for help with a solo erotic act... to my surprise, she agreed! In the hospital, she secretly took care of my injured body while gently handling my penis, and even straddled me with a slow, sensual hip movement in a slow riding position. Although she initially resisted, she became serious with my fully erect penis and couldn't hold back from ejaculating inside her vagina in three rounds!
