Staking Her Claim

Secret Santa Fic for zip-goes-a-million. Sybil and Tom have a newborn baby, and Tom is on two weeks paternity leave. He is a teacher, either English or history, in a senior school (teaching ages 11-18) and he comments about how some of the older girls are going to miss him for two weeks as they have a bit of a thing for him, to which Sybil decides to 'claim him' as her own.
