Sylveon: Shattered Innocence

The story begins with a pokemorph Sylveon (gender does not matter). It is innocent and cute. It lures a victim to its home or wherever it lives for a night of promised fun. Upon entering, everything seems fine, until the victim is led into the bedroom where everything is dark. The victim is scared and the Sylveon uses its feelers to calm them down. It leads them over to the bed and sits them down. In the darkness, the door's lock clicks and the Sylveon flicks on a dim light to set a romantic mood. Something is off about its expression. It seems sinister in some way. Be it, a twisted grin or look in the Sylveon's baby blue eyes. One thing is prominent above all else, the faint stench of rotting meat.

The Sylveon uses its feelers to once again calm the victim and leads them into a kiss. It does not use the draining ability just yet and a heated make out session commences. The victim is distracted by the continuing stench and wants to investigate. The Sylveon shrugs it off and waits patiently, keeping a feeler on the victim to keep them calm. The victim looks around and eventually finds the source of the stench.

Under the bed are half a dozen bodies, withered, and rotting. The draining effect of the Sylveon's kiss giving their skin the appearance of beef jerky. Some of them appear to be partially eaten as well. The victim begins to panic, become to scared to be calmed down, but it's too late. The Sylveon uses its feelers to bind the limbs of its victim and forces a kiss. With that done, it sucks its victim dry. Combined with the calming effect of its four feelers, the victim is calmed while this happens and doesn't offer any resistance. Its life is quickly ended and the Sylveon is free to search for another.

The concepts presented here are extremely simple, but leave enough of an idea to form the base design of an OC. Anyone is free to use them in their own work. Just let me know, I'd like to see the results.
