Finally landing a job, my brother and his wife celebrated with me. We happily drank together, but my sister-in-law Rui was already drunk, her senses completely blurred. When my brother went upstairs to take a shower, leaving us alone, the drunken Rui forcibly tried to pour me another drink. Then, saying "Let me clean it up for you," she began licking the spilled liquor from my lips. Overcome by the warmth of her mouth, I couldn't resist reaching for her chest. A dreamlike scene unfolded before us.
