Felching - The act of sucking semen from any human orifice, eg. anus, vagina, it can be done with a drinking straw when semen is deep inside the rectum. Urban Dictionary Couldn't find this in any of the threads, although it might be there under another name. I go down on Silverette after I've cum in her, and yes, I encounter my own semen, and yes, I swallow a mouthful. But, I've never done this, at least not as a deliberate act. Anyone ever done this?
