The British band - which is comprised of Tom Fletcher, Harry Judd, Danny Jones and Dougie Poynter - have joked that fans who log on to their Super City website will be treated to the X-rated content if they accumulate enough points by interacting on the site.
Tom said: "There's a whole social networking side to Super City, like Facebook, so you can log on and update your page."
Danny added in an interview with Recognise magazine: "We can do web chats from anywhere on our laptops, it's amazing. I've done a few from my house and one from my bed.
"Fans have their own profiles and they get points if they do things like upload a picture and, with us, points win prizes. You can get private phone calls from us, emails, a sex show . No, no I'm joking! It starts from little things to big things, like a meet and greet."
Asked how many points fans would need to view the sex show, Tom said: "A million points.
"What's on the sex show? Is it us doing each other, or them?"
Danny said: "That's on the adult version of the site. Yeah, you superimpose yourself on a picture that we made so it looks like you're getting done by us."
