The handheld device and receiver connect two equipped endpoints. The portal bore creates a pair of wall portals and a body relay for their occupant. Both use the generic interaction route API.

Controls

• Link the handheld device and receiver by using either item on the other.
• Put the receiver in a genital slot or the mouth slot through the interaction panel. It doesn't show on examine, and a mask can be worn over it.
• Activate the handheld device in hand to cycle the target used when selecting the groin. Other selected body zones choose their corresponding endpoint.
• Use the handheld device on yourself or someone else to put the part you aim at against it, the groin using the device's target. Ctrl-Shift-click it from up to a tile away to open the interaction panel of the receiver's wearer instead, listing everything your own parts can do through the portal. The wearer can do the same to reach their own receiver.
• Use one linked device on another to pick from the interactions between their two wearers. The device in your hand is the active side.
• Climaxing from your penis with an open device in reach offers it as a place to finish. A receiver on a penis gets the load on it, any other part inside.
• Right-click the device or receiver to toggle that item's anonymity. Alt-click either linked item to unlink it.
• Use the bore on two supported walls to create its portal pair. Activate an empty bore to change modes; activate it after placement to collapse its portals.
• Right-click an unoccupied wall portal to change both endpoints' mode. Buckle into one endpoint to create the relay at its peer, then unbuckle to leave. A gloryhole relays the penis and balls, and a wallstuck portal everything below the waist. Interactions with the relayed half only work next to the relay, and the rest of the occupant only in person.

Ownership and validation

The handheld device and receiver are linked peers. Neither owns the other: unlinking or deleting one clears the surviving item's reciprocal reference. Equipped receiver authority comes from its exact inventory slot, not its location inside a mob's contents or its cached target alone.

The bore owns its wall endpoints. Removing either endpoint collapses the pair. The occupied endpoint owns its relay and borrows the occupant; teardown deletes the relay and restores the occupant's presentation. The interaction component only observes the relay through a weak reference. Keep teardown idempotent because endpoint, occupant, and relay deletion can enter the same cleanup path.

A worn receiver is always open: it sits on its part underneath any clothing, so clothing, masks and sheaths never close it. The device end follows face to face exposure rules through portal_target_is_accessible() in the human helpers. Slot and link checks stay with the items that own those relationships. Physical access and visible sprite state are distinct: rendering checks native appearances separately and copies them before filtering. The occupant's preferences are never changed: a gloryhole occupant's penis overlay refuses to draw for the session, and a wallstuck occupant has body layers stripped as they are applied. Both keep a rebuild between queued refreshes from showing the hidden body for a tick.

Routes in portal_interaction_routes.dm bind interactions to their current endpoints using weak references. Revalidate after prompts or delays so unlinking, equipment changes, preference changes, or a replacement session cannot authorize an old action. Both participants must allow ERP and sex-toy use.

Deployment configuration

Handheld interactions resolve the names in the device's interaction_map through GLOB.interaction_instances. A deployment must supply the corresponding JSON definitions under config/nova/interactions/ in the server's working directory. The repository's example interaction files do not supply that complete set.

Each part pairing lists one or more names, default first. A mapped definition must be lewd, have usage = "other", use a visible category, and may only require the genitals at its own two endpoints. The validator rejects absent or incompatible definitions. JSON filenames do not form the contract; the loaded interaction names and metadata do. See the interaction datum for loading and message-template fields.

Tests

code/modules/unit_tests/~nova/portal_device.dm, portal_lifecycle.dm, and portal_routes.dm cover equipment authority, rendering invalidation, ownership, route execution, and message formatting. Shared fixtures live in portal_test_helpers.dm. Default tests install temporary real interaction datums and use neutral message templates, so the ordinary CI deployment can run them without production interaction JSON. Each test restores any registry entries it replaces.

Run the DM suite from the repository root with tools/build/build.bat dm-test on Windows or tools/build/build.sh dm-test on Linux. For a focused local run, temporarily add TEST_FOCUS(/datum/unit_test/portal_device) and TEST_FOCUS(/datum/unit_test/portal_lifecycle) after the test includes; remove those focus declarations when finished.

Adult items

A new item family gets its own file and icons here; an addition to an existing family goes in that family's file. The lewd items config removes every item (_erp_disabled_item_enforcement.dm), and the adult_items_kill_switch unit test checks the top types each family lists in adult_items_gated_types() (_gated_types.dm). A new family adds its line there.

• Medipens (medipens.dm). Five single-use 30u medipens: crocin, hexacrocin, succubus milk, incubus draft, and the La Coom Bomb (10u each of the last three), plus a box with one of each. LustWish sells them (the hexacrocin pen, the La Coom Bomb and the box once hacked), and they're in the Erotic loadout.
• Condom box (condom_box.dm). Ten condom packs, and it only holds condom packs. LustWish and the Erotic loadout.
• Bluespace fleshlight (fleshlight.dm). Catches an immovable rod, which flings the user up to 12 tiles along its path to a soft landing. A wizard in rod form is set down unharmed. A premium LustWish item at ten command paychecks.
• Leash (leash.dm). The leashed follows the holder's route a step at a time: round corners and hazards, through doors, up and down stairs. Where they can't follow, the leash goes taut and holds the holder at two tiles. A leashed who falls drags their holder to the hole after a moment to let go. A dropped leash stays hooked and trails the leashed, and anyone their sex toy preference allows can pick it up. It unhooks when the holder uses it on the leashed, when the leashed breaks free, or with the safeword. A line in the strap's colour runs from the holding hand, or from the leash on the floor, while the two are in reach.
• Pointe boots (lewd_shoes.dm). Ballet heels with the feet held en pointe, GAGS, with digitigrade sprites. LustWish, the shoes loadout and the Grimoire Libidine NIFSoft.
• Latex half-catsuit (latex_halfcatsuit.dm). The latex catsuit without the legs. It picks its male or female sprite by body type, previews included, and has digitigrade, Vox, Vox Primalis and Teshari sprites. Unlike the catsuit, it doesn't bulge or hide the wearer's parts or taur body. LustWish, the under loadout and the Grimoire Libidine NIFSoft.
• Paw mood and cat paws (lewd_gloves.dm). Paw mittens give the paw mood while worn. The cat paws are bigger GAGS paw mittens with toe beans and a cuff tag. Both need the sex toy preference. LustWish and the Erotic loadout.
• R.U.T.T. (rutt.dm). A much stronger aphrodisiac than hexacrocin that can cause climaxes, behind the aphrodisiac preference. Mixes from crocin, dopamine, femcum and epinephrine at 322K. Dopamine, which only came from climaxing, now mixes from diethylamine, ephedrine, hydrogen and phenol at 373K. The bottle, pill and Rut-Kit neuroware are in a hacked LustWish; the bottle and pill are also in the Erotic loadout.
• Denbu tincture (butt_enlarger.dm). Grows the butt up to the largest pickable size, behind the butt enlargement preference, and grows one on players who allow new genital growth. Clothes strain and hurt over the last two sizes. A camphor overdose moves the butt back to its preference size. Mixes from saline-glucose, sugar, silicon and crocin. LustWish and the Erotic loadout.
• Bridle (bridle.dm). A three-colour GAGS bridle. Lowered blinders darken sight like a welding mask, and a set bit muffles speech, emotes and spoken spells. Toggled with action buttons or alt-click, or from the strip menu by someone with ERP on, if the wearer has the sex toy preference on; that warns the wearer and is logged. Securing the straps locks it. LustWish and the Erotic loadout.
• Lustwish MOD suit (lustwish_mod.dm). The standard MOD suit in LustWish's skin, with a purple hardlight. The hypnotic visor module hypnotizes the wearer like the hypnotic goggles, while on, or always once its wire is cut. The remote control module comes with a remote that controls the suit from up to seven tiles away: activation, parts, modules, lock and forced emotes. The visor needs the wearer's sex toy preference; the remote needs that and the holder's ERP preference. Sold in LustWish's MOD Suit category.
  • Known issue: a forced emote starting with "says", "exclaims", "yells" or "asks" shows the wearer "Invalid emote." and tells the holder nothing, because the custom emote's own check (emote_is_valid()) judges the wearer.
