My sister, who is usually sweet to me like a mother, is planning to get married soon. One day, when I started my daily masturbation routine, my sister saw me at an unfortunate time. She looked at me with a gentle gaze and said, "You won't be able to see me anymore because you're going to get married soon. If you're in such a difficult situation, I'll help you out just once♪" She gave me a deep kiss, licked my face, licked my nipples, and even gave me a finger blowjob. She even gave me a slobber-covered vacuum blowjob and ball-sucking, which made me get a rock-hard erection and I couldn't help but cum.
