My Sweet Boyfriend's Wicked Birthday Gift: 24 Hours of Nonstop Orgasms

"Not enough for you? ...Then no more 'normal.'"
Her sweet boyfriend overheard her true feelings—and shattered his own self-control.

Sayo and Haruto have been together for a long time—the kind of couple everyone envies.
First love. First kiss. Fireworks on a summer night.
But somewhere along the way, those racing heartbeats turned into "the usual."

She's happy. And yet, something is missing.
One night, Sayo lets her true feelings slip:
"It's become completely routine. Like a chore.romance

She has no idea Haruto heard every word.

Because he cherishes her, Haruto has always been gentle in bed—never pushing her too far.
That was his rule.
But with that one confession, the instincts he'd kept locked away begin to break loose.

"If you're going to think I'm boring... then I'm done holding back."

Then comes Sayo's birthday.
Dinner overlooking the city lights, the wallet she'd always wanted... and "one more gift."
Inside the box: restraints she's never seen before, twisted toys, and a lewd costume.

Still wearing that sweet smile, he begins 24 hours of nonstop, relentless pleasure.
Trembling with shame, she feels her boring routine stripped away, piece by piece.
Again and again, he takes her somewhere "the usual" could never reach—

Until Sayo's body no longer craves her sweet boyfriend...
but the raw, untamed man beneath.

A sweet, merciless birthday gift that breaks her routine for good.
Once she's had a taste, there's no going back to "normal."
