For once I'm making an upload in the SFW part of this site, so let me remind you this is part of the 80s adult anime Cream Lemon, usually featuring all kind of sexual situations and plenty of lolis :o.
This one is dedicated on the most known heroine of the series, called Ami. Mostly songs, almost like a giant music video, it shows some events happening between Ami Again (ep 5) and Ami III (ep 13). It has also extracts from ep 5 and Be My Baby (ep 1). Ami is spotted by some impresario and make her debut recording, but also learn "the hard way" the habits of show-business...
As you can expect there is no sex, but it can be still enjoyed for the 80s style music, sung by Ami herself :D
