MomsTeachingTeens is now a mostly exclusive collection, so most of the videos have pretty consistent quality. Some had a scripted vibe going on, while others went with a reality scenario (the pick-up on the street, etc). Also, while the vast majority of the scenes were in English, I did come across one German episode.
The site is updating once a week and at this point there are 193 movies. Site design is clean and navigation is simple and pleasant. Each scene is represented by a large image and clicking on it will take you to the scene's page where you can check out the photo set and get the video.
Each episode can be viewed in an online Flash player or you can download the scene in either clips or a full-length file in MPEG and Windows Media formats. Video quality does vary throughout the site. Many have good to excellent-quality playback, but some only have a mediocre-quality file available. The images also vary. Some sets are vid caps, some are good quality and others have high-res images. In total, you get about 170 sets of actual photos.
If you don't mind the nonexclusivity of the porn, then I'm sure you are already thinking about signing up. However, if you are on the fence about it, let me tell you about the bonuses that come with your membership. They include a few older woman/younger teen DVDs and access to 22 feeds, like Couple Fucks Teens, Anal Dildo Lesbians, XXX Orgy Parties and Her First Anal XXX.
More consistent high-quality material would be nice, but given the amount of stuff available and the many bonuses, a membership at Moms Teaching Teens is worthwhile for anyone into mixed-age FFM threesomes.
