How to Get the Achievement Tsunami in Return of the Boogeyman

Tsunami is an achievement in the game Return of the Boogeyman. Due to it being a visual novel, all you have to do to get this achievement is progress the game.

Tsunami Achievement

Every achievement in Return of the Boogeyman has a moment that defines it. Hot Bath is the stillness. Ghost is the grab. Pie is the dare. But Tsunami? Tsunami is the moment Natalie stops being able to think — and the game makes damn sure you know it.

The description reads: “A powerful wave of The Big O swept over her!” And if you’ve played enough of this game to know what the boogeyman’s tongue can do, you understand that “wave” is doing a lot of heavy lifting in that sentence.

This isn’t a ripple. This isn’t a shudder.

It’s a full-body, mind-blanking, consciousness-altering orgasm that hits Natalie so hard she grabs her own head like she’s trying to keep her skull from splitting open.

And the thing that causes it? His tongue. Inside her. Deep enough to reach places no human mouth ever could.

Steps to Earning the Tsunami Achievement

Step 1: Tsunami triggers during the intimate sequence — after Muff, after his fingers have learned her, after he’s mapped every nerve and found every spot that makes her gasp. He’s got her worked up. Slick. Swollen. Desperate. And then he pulls his fingers out and moves down her body.

Step 2: The boogeyman positions himself between her thighs, that massive head lowering, his mouth approaching her bare, shaved pussy.

Step 3: Watch her writhe on that tongue.

Not a lick. Not a tease. A push — that broad, ridged, impossibly long tongue sliding deep into her dripping pussy, deeper than any human tongue could reach, deeper than fingers, deeper than anything that isn’t his cock. The ridges drag against her walls as he pushes in, and the heat of it — that signature boogeyman heat — fills her from the inside.

Natalie’s back arches so hard her spine cracks. Her hands fly to her own head, fingers clutching her scalp, palms pressed against her temples, like the pleasure is so overwhelming she’s trying to physically hold her skull together. Her mouth is open. Eyes wide. That reddish glow reflecting in them — arousal or madness or both, the game doesn’t distinguish.

He tongue-fucks her. In and out. Deep and slow at first, letting her feel every ridge, every inch, the way he curls inside her and presses against the spot that makes her vision white out. Then faster. His jaw working, that low rumble vibrating through her entire pelvis, his tongue reaching places she didn’t know existed inside her own body.

And she comes.

Not a regular orgasm. Not a buildup-and-release. A tsunami. A wave that starts in her pussy — clenching around his tongue, flooding his mouth — and radiates outward through her stomach, her chest, her limbs, her fingertips. Her whole body seizes. Her thighs clamp around his head. The sound she makes isn’t a scream — it’s beyond screaming. It’s the sound of a woman being completely, irrevocably undone by a mouth that knows her better than she knows herself.

Tsunami. The Big O. The wave she never saw coming.
