SugarInstant started out as SugarDVD and was known as the Netflix of porn, offering rentals of adult DVDs by mail. But SugarInstant is now a leading streaming service, providing unlimited streaming of adult films on the Roku, Playstation, Google TV, iOS and Android mobile devices, XBox, and PC/Mac computers. SugarInstant offers a mega-size library of over 2300 full-length feature films and many thousands more scenes, all in HD quality.

The SugarInstant video library on your Roku may seem rather simplistic at first - you'll find 100 titles each under the categories of New, Trending, and Scenes, along with a listing of 100 performers. But select the Menu option in the top right corner of the SugarInstant home screen, then go to the Browse option, and you can browse by 103 categories that include Water Play, Public Sex, Cum Swapping, Grannies, Cock Play, Female Domination, Squirting, Home Made Movies, and many more. Or browse by Scene Tags like Blowjob, Anal, Doggy, Cumshot, Masturbation, Rough Sex, and Cowgirl. Or use the search function - enter any term to search on movie title, performer, and movie and scene category.

If you find it easier to browse and search on your computer, go right ahead. Select any movie or scene, click the "Favorite" button, and it will be available in the Roku channel in your Watch Later list, which can also be found through the menu option in the top right corner of the SugarInstant channel home screen.
