A young man is kidnapped by two bandits while gathering herbs in the forest and awakens in a hidden land where he's the only male among a sea of beautiful elven maidens.
Concise description: male character gets accosted, but it turns out he's been *koff-koff* "selected to help restore the population of a village of Elves. In fact, said village is inhabited by a tribe of Sexy Elf Onee-sans (some of whom seem to be also very much horny for male contact), and (wouldn't you know), there's not another male in sight.
Doesn't take much to figure out what's going to happen next.
Can't say for certain if this is a one-shot, or the beginning of a series; personally, wouldn't mind the latter option. Guess we'll see, won't we?
