Twinverted

Puckentine! Its just after the events of the great tuna jump and Sam asks melanie to come visit, but first she wants her to pretend to be sam so her sister can go and sort things out with freddie once and for all. But melanie is a convincing mimic and Cat is still feeling affectionate and needy after the events of the Jade/Freddie/Robbie debacle. Rated M for melanie's gettin some.
