Willing (слэш)

Harry's been missing since he was 9 years old, the wizarding world have been looking him for seven years. Since he was eleven years old and did not come to Hogwarts. He's Seventeen when they find him, but they are in for a shock if they think he'd do what they wanted. Turns out Harry has known Severus for years, he's a metamorphamagus. Dumbledore's manipulations are found out, the world is in for a shock. I want to show a caring side to Dom/Sub so there won't be a rough side to be seen here.
