Well, I'm certainly interested, though not sure if I'd be able to consistantly keep up the multiple paragraph posts.  Reguardless, I am still interested, but feel free to deny me if you think it'll be a problem.  Without further ado, these are the pairings of yours I'm interested in.

Pet x Owner
Brother x Sister
Father x Daughter
Teacher x Student
School Doctor x Student

So if you do choose to accept me, you can pick which one you wanna do the most
