Revenge is a Sweet

When Ron's brothers heard what happened to him, they were furious, so they decided to help out with Ron and Harry's plan for revenge on Romilda. They developed a new love potion, but this one was incredibly powerful, and they combined it with a powerful Spanish Fly. Whoever ingested this potion, would fall madly in love with any adult she came across for 24 hours. Even if she ran into 40 adults, male or female, she'd fall madly in love with all of them, and not only that, she'd crave sex with all of them and freely offer her mouth, pussy, anus, hair, breasts, or whatever they wanted to them.

The Weasley's and Harry figured Romilda would run into at least 30 7th year students, 5 professors, and probably Filch in an average day. If the professors saw Romilda throwing herself at them, they may try to give her an antidote, so they decided to wait until Saturday to slip her the drug, which they injected into one of her favorite sweets, bundled in a box with a note: Romilda, Thanks for all you do! A friend.

They sneaked into her room and left it on her bed while she was taking her morning shower.
