Recursive penetration is when someone is being penetrated through an orifice that is currently inside someone else, such that in order to access it from "the outside", the "outer" must be penetrated to reach the "inner" one. In other words, the destination orifice is (at least) "one level down".

This usually only makes sense in vore, in cases where a prey is penetrated by someone outside (who is then also penetrating the pred to get there), but also works in cases like matryoshka_sex (where an unborn baby is penetrated through the mother's womb, via in_utero_penetration) or possibly some goo creature enveloping someone else.

Like with penetration_tunneling, internal orifices in situations like the cervix during cervical_penetration, the urethra during slit_sounding, or the "inner mouth" of xenomorphs aren't "re-counted", so these scenarios don't qualify as recursive penetration on their own.

• recursive_vore: Vore multiple levels down instead of penetration
• thread_transfer/serial_threading: Penetrating multiple people at once in a chain instead of in levels
• penetration_tunneling: Penetration of someone whose other end is partly inside someone else, somewhat like a living condom. May turn into recursive penetration if the penetration continues once the prey goes completely inside.
• penetration_interlock: Similar to (but distinct from) recursive penetration in the case where the prey ends up penetrating/being vored by whatever is penetrating the "outer" orifice.
• through_body/bulge_insertion: Use of bulges in ways that may involve penetrating someone else in a kind of train position, though this wouldn't be recursive_penetration.
