(This story was written before SCP-166's File was changed on the website) SCP-166 (The Teenage Succubus): SCP-166 appears to be a female human in her mid to late teens, of average height and slender build. Medical and physiological analysis indicates several deviations from baseline human norms, including accelerated hair growth (approximately 20cm per month), vulnerability to airborne particulate matter such as cigarette smoke and aerosols (which can induce symptoms similar to an acute asthma attack), increased sensitivity to pressure ulcers, and alterations in dietary requirements. SCP-166 is noted for her unusual effect upon human males. Upon establishing visual contact with SCP-166, 100% of human males tested attempted immediate sexual contact, regardless of their normal sexual orientation. In approximately 70% of these test subjects, the impulse faded after being removed from SCP-166's presence. In 30% of these cases, however, the desire turned into obsession, resulting in violent attempts to gain access to SCP-166. Class-A amnestics were efficacious in 43% of these cases; the remainder required termination. SCP-166's effect on males causes her a large amount of distress. For this reason and others, contact between her and any human male is strictly prohibited, but is tested weekly with different types of males. Only women are allowed to engage and work with SCP-166. Testing went on as usual, until one day...
