She's My Vampire

You were enjoying a nice hiking trip up in the mountains until you got lost in the woods after a mishap at the peak. Luckily, you stumble upon an old mansion in the woods that's inhabited by three BEAUTIFUL sisters! They offer you a room for the night, but something seems a little bit off about them. Before you know it, you find yourself chained to the wall in a dungeon! It turns out the three girls are vampires and need YOUR blood to gain more power as vampires!

Without a choice, you end up being imprisoned in their mansion waiting for the day of the ritual to come. But as you spend more time with them, you begin to realize that there's more to these vampire girls than just blood lust...
