Gyaru Room!? The Hangout Spot for Gyaru Near the School

You picked up the mysterious cat Haru a month ago who had mysterious powers.

One time a day, it will grant you a small wish.

You decided to ask Haru to attract the lady in your apartment complex but...

Waifu’s Love Room is an interactive point-and-click hentai minigame that allows you to customize and play with your Waifu. There are more than 100 options varying between hairstyles, gloves, socks, face paint, colors, and much more. Your Waifu can be posed in 9 different ways.
You can approach the Waifu in three different ways, using your dick, tongue, or hand. Fill the pleasure bar to make her happier, but remember, she’s always up for more. You can penetrate her pussy, mouth, or ass. You can also lick her body.

It’s a crappy game where you work part-time, do muscle training, and petrify the girl that turned you down.

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!

Kousaka Yuusei had just transferred to a traditional all-boys school.

However due to the declining student population, the school enacted a policy that would allow non-male students to attend the historically all-boys school. However, as a side effect, quickly after that, there were practically no ordinary male students left.

Soon afterwards Yuusei gets introduced to two charming "girls", Asuka the sultry ganguro and Miyabi the refined (but secretly lascivious) young lady, he suddenly becomes overwhelmed by their alluring faces and bodies. Until they reveal to him that they are actually traps, Yuusei become shocked at the revelation, how could these two traps be more attractive than most girls?

Asuka and Miyabi become interested in Yuusei since he is an ordinary male which has become a rarity in this school where the vast majority of the student population is made up of trangirls, this is the start of Yuusei's story in this school filled with traps where he will develop a relationship with Asuka and/or Miyabi.
