Egyptian Sex Manuals

Origin
Sexuality in ancient Egypt was very open. (See here for more information of Egyptian Lifestyle in this regard.) Sex manuals themselves seem to have been common in the ancient world, though they did not always discuss sex. Despite the existence of sex manuals in many cultures around the world for many centuries, Western culture banned them for a long time.

Effects
Reading the Manuals allows the user to perform complex sexual acts. However, each participant becomes infertile afterwards. The infertility only takes place after the act is performed with a partner.

Collection
Records of this artifact's existence date back to Warehouse 3, during the reign of Emperor Tiberius Augustus Caesar. During his exile on Capri, he had young girls study these manuals in order to please him, after which they would be killed. Although agents were aware of the artifact's existence, they were not able to get onto the island to collect them. After Tiberius's death, the Warehouse attempted to collect the Manuals, but found that they had disappeared, along with several other artifacts believed to be in Tiberius' possession.

The artifact reappeared several times over the centuries, though the Warehouse was never in a position to collect them. Finally, the artifact appeared in Germany in June 2015, and Agents Arthur Neilson and Megan Wilcoxson travelled there to collect it. Agent Wilcoxson, not initially knowing that the manuals were an artifact, fell under the influence of them. Luckily for her, Artie neutralized them before she performed the acts and became infertile.
