Saenai Ore ga, Succubus Netochaimasu!?

I'm an ordinary guy stuck in a tiresome office job, with no girlfriend and no life. I was forced to go on a company trip, when I met a succubus in the hotel.
Is this finally my chance to lose my virginity? Or so I thought, but it seems like the succubus is already having an affair with a handsome coworker I don't like… But it seems like there's an opening I can take advantage of? I'm going to take a gamble on this once-in-a-lifetime opportunity to steal the succubus away from my coworker!
