This is a simple 壁纸 but it's cute :3. It's 袜, 放养 from Panty & 袜, 放养 with Garterbelt. The 日本动漫 isn't 安全 but this fanart 壁纸 is ;P The link for the much bigger version is here ---->
link Also, I'd recommend using either zerochan.net 或者 konachan.COM (konachan.COM has 安全 Mode while konachan.NET has Explicit Mode) for looking for wallpapers. Deviantart.com is good too. konachan.com is very hard to navigate in the beginning at least because the 搜索 thing is really weird.
If 你 make an account on zerochan.net 你 can also do some really cool filtering. Like okay 你 don't want anything mature right? Well, there's a thing where can add 标签 of things 你 DON'T want to pop up in your 搜索 so you'd put things like "Ecchi" 或者 "Hentai" and it'll filter those out for you. 你 can also add 最喜爱的 标签 so instead of having to type something in over and over again your 最喜爱的 标签 appear on the homepage and 你 can just click those.
Zerochan.net combines your 最喜爱的 标签 and your Disliked 标签 when searching so 你 can 搜索 for "Wallpaper" and your 最喜爱的 标签 will come up most often and no Ecchi/mature content will ever come up since those 标签 are disliked. Pretty nifty ;D I used it to filter out 矢追 and annoying Final 幻想 characters and it's awesome. 你 can filter out Mature stuff on Deviantart too but 你 can't filter out specific things 你 don't like, like 你 can on Zerochan.net
