Harry wanted to verbalize his words but couldn't. The spell cast by Bellatrix seemed to be having a minor side effect akin to a drug as his body relaxed and all he could manage out were breathy whines and whimpers. His butt did clench around her like a vice, almost like a skin tight glove as he felt her reshaping his insides to accommodate her girth. Harry had never felt so full before, and Bellatrix was only sheathed halfway into him, causing a lewdful bulge in his belly where her cock lay quite pronounced.
