Initiation of a Reluctant Slut

The school's reputation precedes it - a place where the innocent go in and the depraved come out. Our naive protagonist is no exception. His sister, a veteran of the school's debauchery, takes it upon herself to guide him. She's not gentle, not tender. She pushes him onto her bed, straddles him, and grinds against him. He's hard, she can feel it. She laughs, a sound that's both cruel and excited. "You're mine now," she whispers, before pushing him down, ready to teach him the ways of lust.
