subreddits related to r/yiffgif
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.
There was /r/dragonsfuckingcars, /r/carsfuckingcars, but no /r/dragonsfuckingdragons. Seriously? Welp, that problem is over.
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.
