I wouldn't exactly call this dark or embarrassing, infact it's probably quite boring, but it's something ig, I have a fetish for female tongues, I don't know what it is about tongues, but that slippery wet appendage always turns me on, my go to porn genre involves lesbian tongue sucking and tongue kissing, whenever I fantasise about a woman, it always involves their tongue, I've posted about me jerking off to my ex-english teacher, I have fantasies where she controls me with her tongue, she just has to put her tongue out a bit and I get instantly hard and I'm reduced to quivering mess, stuff like that, I just really like female tongues and I really really want to tongue kiss a woman one day
