The Christmas Succubus was observing her work as Christmas dawned, when she felt pain. Her body twitched like she had a seisure, unseen by the people around her. But not the Dark Force as it discovered an element of it's summoning it didn't notice.
The Dark Force had thought it had summoned a Christmas theme demon of evil sexual perversion. What had happened was it has summoned a succubus of great power, a queen of her kind, and bound her to the power of Holiday spirit. However, holidays end and holidays change. And so did the Succubus, turning from a Christmas Succubus to one of another Holiday.
There were many options. New Years, Martin Luthor King Jr. Day, National Sausage or Cherry day. However, in the mind of many people the major holidays went as such. Christmas was fused with New Years as they were a week apart, so the next major holiday in people's mind was Valentine's day... the Day of Love.
Which was how the Succubus turned from something like the demon of Christmas, Krampus... into the spirit of Valentines day, Cupid. Gone was the horns, hooves and fur. But much remained the same. She became a blond hair, blue eye beauty. Her chest remained the same, but with the straps of her quiver just barely covering her nipples. She didn't wear anything on her legs, her cunt covered with a white thong which looked a little like a sexy diaper. Dark crimson high heel boots on her feet matched her quiver and it's straps. She had a scarlet bow, which matched the arrows which a spikey heart designs highlighted in red. The arrowheads being barbed as well.
She stood up, health and strong again. She turned to the Dark Force and said, "Looks like I'm back in the matchmaking business. Let's reward our naughty boys and girls with the love they desire."
She then flew off to start her mission till the new holiday ended. Meanwhile, her previous matches only strength as she gained holiday spirit power.
