Select your destiny. Would you rather get felched or do the felching?
Felching is a sexual practice involving the licking or sucking of another person's anus. In particular, it refers to the act of sucking semen out of the anus of one's partner. The semen has been ejaculated into the rectum via anal sex. The act of sucking the semen and then passing it, through mouth-to-mouth or open-mouth kissing, is often referred to as "snowballing"; although the latter is typically associated with semen ejaculated into a mouth from fellatio.
Felching may also refer to the anal insertion of a small animal (usually a gerbil) for the purpose of sexual stimulation.
