This is a place that welcomes all feral Pokemon porn. Anthro and trainer are only allowed when paired with a feral Pokemon. Fan made characters such as Lunamew and Nicobay are also welcome, granted they abide by the rules and are feral renditions of Pokemon.
This subreddit is meant for yiff between partners or more who are showing deep bonds, passionate love-making, love in general, etc. generally in a pornographic way. Examples can be passionate kissing, cuddling, slow/moderate penetration, though it is not limited to these.
