This is by far the freshest wasabi I have ever experienced, and it was even more intense than I expected. A dear accomplice sent me wasabi rhizomes and a special grater as a gift, so hurting myself with them was just the right thing to do! I peeled a rhizome and then pushed it into my urethra without any lube at all, so nothing would interfere with the sensations. Then I tried the grater for the first time, creating a creamy paste of wasabi to smear over my clit. It was intensely painful! I've played with both true wasabi and horseradish on my genitals before, but I don't remember it ever being this difficult to tolerate. When I could catch my breath, I grated more wasabi, and left it on the end of the rhizome as I pushed the root back into my peehole. Then I challenged myself to cum while fucking my urethra with the viciously burning wasabi!
