I also have a public folder called 'Contractions' in my Favorites collection. There are some very good examples in there but the difficulty is that they keep getting deleted for one reason or another. But have a look at that. You might care to check out some of the other folders as well. I have about 150 folders. Some have only a few videos but others have a few hundred. There are 10,000 in the default collection (minus the ones now deleted or made private) so probably about 5,000 active.
Excellent contractions: small nearing orgasm at 01:11, full orgasm at 01:46-54, and even stronger at 02:10-35. One of the finest contractions videos to be found anywhere.
I love her moaning sounds watching her play while listening to her whimpering really turned me on then when I saw her go straight into round two and use her cum to lube her clit so fucking hot she has some nice legs too and theres no way you can fake it because you get to see her ass contract mmmmmmmmmmmm
