MistressJennifer is here to make sure that you naughty guys behave yourselves! This is a hard and heavy Femdom site (as if you couldn't tell from the URL) and she disciplines and humiliates all of her slave men until they're begging for release. There's a large amount of good BDSM/kink material here and the quality of the content has gone up in recent months.
There is a very impressive 507 discipline sessions to go through. They range from bondage, whippings, spanking, sensory deprivation, smothering, cock-n-ball torture, strap-on fucking and the expected assortment of uniform/role-playing sessions.
This Mistress doesn't take no for an answer and she'll give you the stern punishment that you richly deserve. There's a bit of gender-bender intercourse too – you can expect to see some forced crossdressing and humiliation scenes where the obedient slaves get a pounding from Dommes brandishing strap-ons.
The rule of thumb is to avoid the older material. The movies can all be downloaded and watched in their entirety in Windows Media files, but it's the newer episodes that are great in quality, not the older ones.
Same goes for the pics. There are a staggering 507 photo galleries here, but only the newer ones are filled with high-res shots. Don't worry, the high-grade content will make the older mediocre stuff disappear from your mind.
Also, the fact that this site makes multiple updates every week helps. You know there's way more punishment headed your way if you manage to get through all of the material that's currently here. It also mitigates the fact that there are zero bonus sites.
This is a good source of blistering BDSM material and as long as Ms Jennifer keeps posting episodes, this site will remain a heavy hitter.
