Sherlock's little Archie

10 year old Archie from "His Last Vow" has now began studying under Sherlock's wing. Archie's mother demanded Sherlock teaches Archie how to play the violin, but it's hard to teach when the craving for an addiction settles back in. Second chapter gets very steamy with Sherlock and John, so please be age appropriate (18 )! Rated MA for drugs, smut, and mild cursing. JOHNLOCK
