He walked up behind her, placing his hands calmly on her shoulders, looking down at her. "My dear pet, are you really that frightened that I would leave you again? You must trust in your master as Sylvia does. All that happens to you is under my control, you never need to fear to icy embrace of death."
He moved around her, a finger caressing her heart. "See, your very body needs my guidance. Without your master, death would claim you within 5 years, with this flawed human heart." He carefully sliced the organ out, his machines keeping her alive as he worked. "You see..." He sliced the heart open, showing her the scarred, weak inner valves. "You see? Not to worry though, with me, you can become perfection." He set the heart aside, bringing out a strange, violet colored heart with deep purple veins. "7 chambers, twice the speed and strength. You'll have a resting rate of maybe 15 beats, and much more strength when you need it." He placed the heart inside her, the veins moving like tendrils, latching onto her cut veins. The violet color spread through her insides, changing the shade of her body, even the walls of her throat and pussy taking on a violet hue. "There, fixed."
