As you probably already know, Google Play has some really strict policies when it comes to distributing certain contents, which also goes for erotic contents aimed at adults. That's why we have to resort to other app stores to find alternative applications that Google doesn't want you to install on your Android.
The alternative Android app store for adults
One of them is this Nutaku Android Store, a marketplace with games for adults that hosts all sorts of applications that you can download to keep yourself entertained whilst you also feed your randy mind. You'll find all sorts of titles, sorted by categories and which you can also explore alphabetically or using the search tool. The games usually have a Japanese-like manga aspect so don't expect too much realism in the graphical aspect and we can find puzzles, adventures, simulators, role-playing games...
Regarding how the app works internally, we have to mention that it's quite neat and tidy, helping us to manage our downloads and automatically updating all those apps we may have installed. Thus, if you're looking for a slightly different app store, get hold of this APK right now.
