Ok, so in the past, I've made some mistakes... Fighting type, that's a no-go. Dark? Still bad. Rocks? People still waifu rocks. BUT, surely ground is a type that LITERALLY the SOIL BENEATH OUR FEET cannot possibly be riddled with disgusting waifumons. After all. The ground grows the crops which we eat. The ground can be coarse yet smooth. It is mother earth herself. Ground is the definition of purity.

I REFUSE to believe there is someone so desperate to cum that they jerk themselves to fucking ground types.
