ドリアード

A normally kind-hearted plant monster. She was slow to be impacted by the brainwashing (dimwitted?), and looked on in confusion as her Queen and friends slowly changed. But if the brainwashing magic is given a chance to manifest itself, her personality suddenly turns into one of brutality. She is able to trail her roots over an organism, and suck them dry very quickly. Since this process is quick and merciless, she generally doesn’t do it…But when her personality changes, she uses it without hesitation. Having their energy quickly drained like this brings men and women alike fast orgasms. If she’s draining a man, they will ejaculate one time after another while writhing in ecstasy.
