Trap Dungeon! The New Demon Lord's First Job

SHINING, SEXY, STARLIGHT GYARUS! Your house has suddenly become a place for gyarus to gather?! But what are these magical energy or power spots they keep talking about? After fighting evil all day, the best way for a magical gyaru to recharge is to milk a horny boy like you for all his special Mana!

Yui Morisaki is just a regular girl, busy with her regular everyday life like the Karate Club and an unrequited love... until one day she meets a little robot named Polka! Suddenly, she's granted the ability to transform into Radiant Princess Poni Ceres, just in time to fight against the evil forces of Zydarg, an alien organization hellbent on invading and enslaving all of humankind.
 
Fast forward a few months and Yui is coming to grips with her new life, though her heroic activities are starting to affect her grades. But just as she's getting used to dealing with the enemy's regular troops, it seems like Zydarg is escalating the conflict and attacking with monsters. It's time for Poni Ceres to up her game too!

From outta nowhere, you've found your bachelor pad being the defacto hangout zone for a trio of gorgeous gyarus! If your brain wasn't so full of lewd fantasies, maybe you would have paid more attention to their conversations, talking about weird stuff like "power spots" or "magical energy."
...Well, whatever! The instant you get a moment of privacy, you can jack off while their sweet smell still lingers in your room!

As you are out running an errand for the gals while they crash at your place, demons appear, running rampant on the streets. Before too much chaos is caused, the Starlight Girls, the local troop of Magical Girls, in-case it wasn't obvious, arrive!

Instead of fleeing the scene, your prefrontal cortex is clouded by a thick fog of horny thoughts, as you're watching their boobs and butts jiggle around as they activate their magical abilities. Sometime between the battle starting and drool dripping from your mouth, the red-headed magical girl is sent hurtling to the ground in front of you! As you summon your courage, you run over to try and protect the fallen hero, when suddenly a blinding FLASH bursts forth from your house reinvigorating the magical girl you're holding in your arms, as she quickly rejoins the other two, and the trio waste no time hitting their fully charged EX finishing move, STARLIGHT FINISHER! Wiping out the demons and saving the day!

When you scramble home, Chika, Miyu, and Mei are nowhere to be found. You expected the three gyarus to be angry, having been kept waiting for you to return with their snacks and drinks. Maybe after your encounter with those demons, your karma helped you dodge the wrath of hangry gyarus for tonight...

The next day after recovering from your ordeal from the day before, armed with fresh new fap material, you're ready to get to work when, knock knock, Chika comes barging in, dropping work shattering lore in the form of a "tl;dr, me and the other two are the Starlight Girls and you might be the chosen one who can channel magical energies to boost our powers!"

Well that explains why they hang around you so much at least. Today she wants to find out how you managed to give her a mana overcharge yesterday during the fight with the demons. The revelation you two have is; the hornier you get, the more mana that gets produced! So, after a little groping, and a little twerking, a radiant aura flares up from your crotch, bursting through your pants.

Chika is left awestruck! Looks like she is going to enjoy the mana milking process maybe even more than you are! With the exposition out of the way and your objective clear, its time to conquer the bodies of the Starlight Girls with your cock, so they can spend their day fighting monsters and their nights using their bodies to milk you dry of every last drop of your special mana!
