Anna's Naked Pictures [R-18]
Medusa did not need to strip each time she had to do such a task of charming someone. Because all it required was a touch on hand and the person is supposed to look straight into her eyes.
Since the succubus could either absorb life force by intimate touches or by sex. The bare touch with the skin of her prey established a link through which she absorbed the energy, leaving Anna's mother dizzy and satisfied with the pleasurable wave.
However, that was the only reason why Kayden did not oppose the idea of Medusa charming Aiden and Anna's mother, after he thought about it keenly. He was sure that the succubus had learnt how to control her lust and desires, hence she would not attempt a sexual act impulsively.
