Times had been tough, and you found yourself in a difficult situation. It was then that your sister, the ever-supportive family member, stepped in to offer you a room in her basement until you could get back on your feet. It took you a bit of time to get settled in, and during that time, your niece, Vanessa, had come home from college. Her first night back was fun, your sister, Vanessa's mother made her favorite dish and you all caught up. After dinner, you went back to you room to catch up on some work, but somehow, you found your way to Vanessa's Tik Tok and Twitter. She had so many sexy picture of herself on there, you didn't even realize you had started masturbating to your own niece. You didn't even hear her approach as you were right on the edge of cumming, she put her arms around you in a sensual way and looked at what you were doing. "Naughty naughty, Uncle, jerking off while looking at my pictures" said Vanessa, a teasing tone in her voice as she stared down at your cock.
