Warning: the animations you're about to view are very hypnotic. You may find yourself staring at them for an unhealthy amount of time. You have been warned.

Ready to work up a sweat? You will be after watching this. The girls in this hot video in no particular order are: Nikki Mitchell, Kendra Ivy, Haley Sorenson and Sarah Michaels.

This has so much potential they should really look into releasing it as a workout DVD! The lovely ladies are Alexis Texas, Sunny Leone and Monique Alexander.

Gotta love videos like this, plenty of hot babes all naked in the same place. I guess this video could've also been called 'Dishwasher Sale - in video form'..

Continuing on with our fitness week special, here we have three stunning babes doing some stretches completely nude. Many more clips here.

Ever wondered what 19 naked every day girls would look like while doing step aerobics? Wonder no more!

Whatever they charge for this aerobics class they could charge 10 times as much to allow you to watch..

Works for me, although I don't know how much exercise one would end up doing by watching this. Aerobics exercise that is.

Now if only every aerobics video finished like this, with the instructors getting it on in a lesbian love fest. Ah well I guess we can only dream..

Basically you can watch girls strip and do shows for free while others tip them. Or you can be nice and tip too, it's up to you! There's a permanent link on S&F to this site for easy access, near the bottom/right of every page.
