Use Chrome or Google translate on just pixiv.net and you'll easily be able to figure out how to register then you can click the first link to view the artists page and yes this artist has drawn a couple more really detailed tfs in this vein but most have been linked before on these boards.
Also I did post a guide on how to register and change settings to view adult material on that site here:
http://www.process-productions.com/f...8&postcount=33. After registering you're not done and will not be able to view 'adult material' until you change a couple settings so make sure to follow all the directions not just the stuff on making an account.
