OMG!!! I can't get off my knees for being reemed up the ass by this wonderful box. I started with short strokes and increased to 6" at full speed. I came several times in just a hour, with the first load shooting so hard that it landed in my gapped open mouth. I made an adapter so now I can attach any of my dildos to it. I'm now getting 15" shoved into my ass with a 6" stroke!!!!!!
