Idol Comforts is a story written by Kirisaki Nizuki. It ran in Issue 42 at http://s2b2.livejournal.com/248974.html, and is mirrored at http://www.shousetsubangbang.com/mirror/idol-comforts/.
From fail-fandomanon.dreamwidth.org: "babies are bought from their parents at/before birth and raised in this huge ruthless corporation that grooms them for stardom. Those who don't make it as idols are fed back into the system as assistants, doctors, bodyguards, admin, etc. Super fascinating world building and commentary on the relationship between fandom and commercialism. Interesting sex scene too, it's no-touching mutual masturbation with aid of empathic psychic abilities."
