I wanted to give a kuddos to this site. They have a lot of f/m material and update 3 times a month. As with all sites, not all their clips are great, you know a couple guys not ticklish and a couple poor lers, but more often than not, they are good to great. You can't go wrong with Chloe as a ler, her looks, personality and tickling skills make them all good. Emma is another great one who keeps getting better. One of the more recent clips, where she's "practicing her tickling skills" on Sean is one of the best clips I've seen. Great verbal teasing in that one too.
There was one ler, Sarah, that has only 1 clip that I'd love to see more of. She was a good tickler, seemed to have a lot of fun and had great long hair.
Overall, I would recommend this site for f/m fans. If you've never joined, there's a whole lot of stuff to see. Or you could download a clip or 2 first to see for yourself.
By the way, I am not affiliated with this site at all but would like to volunteer to be tickled by Chloe, Emma, Sarah or all three.
