I love big toys and fisting. I have an extensive collection of huge dildos and plugs, including the 5-inch wide plug from bigsextoystore.com. I've even managed to get it all the way seated...once. That was during an all-night fist party and I was in rare form.
My absolute favorite dildo is the Superlance from Creative Mouldings in England. In fact I've had 8 of them...because I wear them out.
here's a quick look at me with one- a minute long, and I'm taking it to the 4-inch wide point.

If you click from there to my profile you'll find a bunch more videos of me playing with toys, getting fisted by a girlfriend and a few guys..
My most recent big toy buy was a silicone Mega Uncut from Square Peg Toys. It's very much a long-term project, it's fucking huge.
I've been playing with my ass since I was 10 or so, off and on while growing up but I've always had a fixation on size from the start.
Even though big toys are fun and do the job of opening you up really wide, they can't compare to the hands of trusted friend fucking you ass. There is no substitute for fisting.
