I fell for my new spouse's child. Her pure, innocent smile and unexpectedly bold actions drew me in. Even though she loves her dad deeply, why won't she let me cum? The way she teases my cock right under her mother's nose makes me think I might be someone special to her. On the final day of her period, I showed her the thick, concentrated sperm I'd held back for a week. She was delighted, smiling at me with such satisfaction. That smile left a lasting impression on my heart.
