I'll start the ball rolling with brief reviews a few classic chounyuu pay sites. The first three that spring to mind are: Mastasia.com, Farangdingdong.com and BEArchive.com.
Mastasia.com is all about gigantic fantasy tits. The tits are rubber prosthetics on real women. Sizes range from about one gallon to ten gallon (8 to 80 pounds each). There are photo sets and videos. Most of the action is solo with a little light lesbian now and then. There's plenty of fake lactation and a few futanaria, with huge spurting rubber dicks. There's also some 3D rendering, both stills and motion. A subscription gives access to all photos and 3D stuff. Not all videos are available with a subscription. Many of the older vids are sold individually on a daughter site. Web site has a fair number of samples which are reflective of what you'll find inside. Mastasia.com is not making any new material. There are about 200 productions already done.
Faragndingdong.com is similar to Mastasia bot with an oriental theme. Huge fake rubber tits with sizes up to 100 or so pounds each, if they were real. There are photo sets and vids. Mostly solo action with occasional lesbian shoots. There's also a little hetero action with a definite BDSM theme. A subscription gets access to all of the accumulated photos sets (perhaps 400 sets). The standard subscription gets access to only a dozen or two videos per month. There's an optional daughter subscription to video archives that more than doubles the number of videos available. Even with both subscriptions, you only get access to a small fraction of the videos that have been produced. There's lots of free samples at Farangdingdong.com.
BEArchive.com is one of the oldest chounyuu pay sites on line. The main theme at BEA is photos of morphed tits. It's a big site with lots of material. There are a few morphed videos, a modest selection of big tit toons, a fair number of big tit and big dick stories, dozens of morph artist collections, a few huge tit news letters and probably other stuff I've forgotten. A paid subscription also give you full access to the user gallery, with all of the old posts from day one. BEArchive is a large site with lots of material... BEArchive is certainly worth a one month subscription of you've never seen it. IMHO, there's not enough new material monthly to justify an ongoing subscription. Check out the free gallery at http://gallery.bearchive.com/ugallery/
. The freebie only covers a few days, so you have to check frequently if you don't want to miss anything.
These are three of the oldest and largest chounyuu pay sites. I hope others will review additional sites. Please give your honest opinions. No one wants to spend money on a bad pay site. I plan to add some reviews of both good and bad pay sites later.
