The Accidental Fathers (or And Bob's Your Uncle) (слэш)

When Harry’s son comes to him with a big problem, Harry steps in to help out. And so does Severus. But Severus’ help comes with a price, which causes another problem. A circular story where Harry ultimately gets exactly what he’s always wanted. Wirten for the 2011 Snape_Potter Cliche Fest on IJ/LJ/DW.
