In order to understand the act, you first need to understand the anatomy involved: Bellwether describes the act as "being [finger-]fucked in one or both of my inguinal canals," which are, as she puts it, the "twin 'pockets' that are situatied in the groin above and behind the testicles and scrotum." Generally speaking, inguinal canals are the canals that the testicles descend from—the same pathways that balls get sucked back into when you jump into a pool of cold water. Bellwether refers to these parts of her body as her "cunts," and uses that chill term interchangeably with their medical name.
In order to penetrate or fuck your inguinal cunts, you need to locate them inside your body. This can be challenging, because, unlike your anus, the entrances to these canals are enveloped by flesh. In order to locate them, FTW advises users to take their hand and feel upward and behind their dick. This is where you'll find the entrances, which Bellwether says are "initially about the same diameter as a finger but will stretch considerably." She advises first timers to "start slowly" and to be careful.
