Elf Harem

For centuries, Elves had no need to reproduce due to their long life spans. However, with the older generation dying off, the new generation has no idea how to partake in the reproduction practice known as 'Sex'. With only a few of the older generation left, time is short. Kidnapping a human(You), you are deemed the reproduction king, meaning any elf girl has to submit herself to you and let you breed her. Will you abuse said power? Or will you be more strategic?
