This is Jorogumo – The Spider Monster Girl
Jorogumo is a Monster with the form of a Spider, that can change its appearance into that of a seductive woman when it wants to hunt a human male. They say even when it is in its human form though, its reflection will show a giant spider.
Their favorite prey is young, handsome men who are looking for love. When a Jorogumo spots a man she desires, she invites him into her home, and he is usually never seen again. They can spin silk threads strong enough to ensnare a grown man so that he cannot escape. They also have a powerful venom that can slowly weaken a man day by day whilst invigorating his libido, allowing the spider to savor everything the man can offer until he is spent. They would eventually release their captive male, and provide him a bundle of silk for the trouble they caused.
Their allure is irresistible, be warned not to be tempted… Unless…
