I finally have something to add to the community. Usually you guys are way quicker than I am.
A while back a came across a hypnosis file, by Lady Lana, that lets you experience for yourself how it is to have a huge penis.
Lots of process, it starts off with you having a very small penis and through masturbation it grows to monstrous proportions.
I've tested it for a while now (can't be showing up here with blanks, now can I?) and although the file doesn't completely work on me yet, during the hypnosis itself I can feel it growing really, really big. There are some post hypnotic effects, but not the full thing. I'll be keeping at it.
If you're curious to check it out, as I was, I've added a link below.
