Funbag Fantasy: Sideboob Story (Kyonyuu Fantasy Gaiden in Japan) is an H-Game and the first sequel to the original game in the Funbag Fantasy series, releasing in 2011 and receiving an English localization in 2018.
Two years after Lute Hende graduated in last place from the Royal Knight Academy, he has become king of Edelland and enjoys a cozy life with his three official & three unofficial wives. Their efforts have granted Edelland an age of stability, cementing Lute's support among his people even with his vulgarity becoming further entrenched in his reputation. Unfortunately, Edelland's success has kindled envy in other nations, especially its neighbor Lingobard.
Following the execution of Prince Bobon at the conclusion of the previous game, Lingobard's King Bazalt I invaded Edelland to claim ownership of the throne. But his forces were routed within days, and he was forced to cede part of his kingdom to Edelland. Hungry for revenge, Bazalt sends his nephew Argent into Edelland to kill Lute with the aid of magical artifacts from Marquis Cuvier, the grand chamberlain of Lingobard's other neighbor Fronce.
Meanwhile, a rift has developed within the Church of the Holy Rood over whether to recognize Lute's demon wife Shamsiel as a legitimate queen of Edelland. On the covert suggestion of Marquis Cuvier, the anti-Shamsiel faction proposes the church send an investigation team to assess her worth. They neglect to mention the additional magic items Cuvier provided to tilt the verdict in their favor.
Funbag Fantasy: Sideboob Story contains examples of:
- All Love Is Unrequited: Nellis begins the story with a crush on Argent, which he never notices because he's too interested in Gladys, who abhors him.
- Blonde, Brunette, Redhead: Lute's official wives at the start: Luceria, Roxanne, and Shamsiel.
- Clear My Name: One of the two main plot threads in the first half has Shamsiel dealing with a smear campaign by political opponents using Shamsiel impostors to frame her for murder.
- Cutting Off the Branches: The only events from the previous game which are treated as canon are the ones leading to the ending with all six women. Everything else, including the entire trip through the Giropon Woods, never happened.
- Fanservice Pack: All six returning women have received new everyday outfits. Overall they're similar to the original ones, but are more detailed and show just a bit more skin. Shamsiel, on top of retaining the inexplicably enlarged breasts she picked up midway through the first game, now sometimes dons an elegant white dress which emphasizes her bust even more.
- Fantastic Racism: Not everyone in Edelland is happy about their king doing away with the demon extermination laws and marrying a succubus. Outside the borders, leaders in both Lingobard and Fronce find it objectionable as well, and the Church of the Holy Rood is in conflict with itself over whether Shamsiel can be queen.
- Gaiden Game: Averted, despite the Japanese title calling it one and the English title keeping the implication. It's a direct sequel to the original game.
- Go Through Me: When a soldier tries to attack Shamsiel after being falsely accused of murder (thanks to her flat-chested impostor), Lute jumps in and takes the hit to protect her, much to Shamsiel's horror.
- Happily Married: The story starts off that Lute has been officially married to Shamsiel, Roxanne, and Luceria. Naturally, their lovelife and sexlife is still going strong. By the story's end, Gladys gets officially married to Lute as well.
- Impostor Forgot One Detail: The impostor Shamsiel commits crimes to frame the real Shamsiel and turn public opinion against her. However, when the fake tries to attack the men at Vunderbalt, they immediately knew she's a fake since they've worked with the real Shamsiel (or rather bossed around by her) numerous times. First, the fake's coloring was completely different from the real Shamsiel. Second, and most importantly, the fake is flat as a cutting board while the real Shamsiel has big breasts and proud of it.
- Porn with Plot: This story deals with life as being the King of Edelland while dealing with other factions trying to demean Lute's rule. Lute must show that not only is he a great ruler, but also to promote peaceful coexistence with demonkind, Shamsiel being living proof. All while Lute adds two more sexy big-breasted ladies to his harem to have sex with.
- Royal Harem: Lute, as king, has Shamsiel, Roxanne, Luceria, Gladys, Isis, and Emeralia from his previous adventures. This time around, Nellis joins the group, for a total of seven women. Queen Aphrodia also begins a romantic relationship with Lute, but does not live with him past her week of "reparations".
- Sitcom Arch-Nemesis: Shamsiel and Gladys are just similar enough in general personality and overall approach to love and danger to get on one another's last nerve. All through the game, the two can bicker over anything.
- Talking the Monster to Death: Unintentionally by Lute. A specter was released in the castle which kills its victims by forcing them to kill themselves through psychological torment. When the specter tries to kill Lute, he completely no sells it. Not only that, the specter's frustrations to get Lute to do what it wants cause it to be Driven to Suicide itself.
- Trojan Horse: Just prior to the true ending, Cuvier shrinks a bunch of his soldiers, hides them in wine barrels, and offers the barrels as a gift while visiting Edelland to sign a pact. When negotiations stall, Cuvier brings the soldiers back to full size, brags that he's taken over the castle, and demands Lute sign the pact. It might have worked, if Argent hadn't told the guards to put all the wine barrels in the dungeon resulting in the soldiers being trapped.
- World of Buxom: Once again, none of the ladies are below an H-cup.
