Rock-man was the first ever tickle material that I came across on the internet way back in 2001. I had just discovered bondage on the internet and was somewhat disappointed that tickling didn't appear to exist until I clicked on a site that went by rock-man. It opened the doors to a world I never knew existed.
BTW...you can find all these same rock-man clips on pornzog.com where you won't get a virus. just type in "nina tickle" in the search bar. The Rock-man clip of nina tickled while tied to a chair will be the first to show up. click on it and it will open a new page where you will also find more rock-man clips. You will then find what is my favorite Nina clip of all time that has her tied while underneath a chair and her legs and feet tied upright against the back of the chair.
