Imouto! Life ~Monochrome~

Shoko Sugimoto has opened a massage salon dedicated to healing both the mind and body, drawing on her extensive qualifications. Joining her as a trusted right-hand partner is Chuck, a massage therapist who specializes in female clients. Together, they've been preparing to provide the ultimate relaxation experience.

On the eagerly awaited opening day, their first visitors are the Otowa couple, residents of Tokyo. Though elegant in demeanor, both wear expressions tinged with worry -- hinting at a deeper reason behind their visit.

For Mari, this is her second marriage. Her first ended due to her husband's infidelity. That's why she now cherishes her life with her current husband more than anything and wants to protect it at all costs.

Their marriage, built on love, has been nothing but bliss. Mari loves her husband deeply, and each day they spend together is a source of joy. However, his demanding job has left them little time to relax and connect.

Then came a rare holiday. Seeing how exhausted her husband looked, Mari wished she could ease his fatigue, even just a little. With that in mind, she secretly arranged for a massage therapist -- a small, thoughtful surprise to help him unwind.

You have a girlfriend.
She's polished, caring, kind, and gets good grades.
You're just enjoying your life with her when one day, you get into an accident.
When you wake up in the hospital, you've forgotten all about your family, friends… and her.
You try to restore your memories, but other women approach you, taking advantage of your amnesia with half-truths.
Can you get your memories back and return to those blissful days with your girlfriend?

Hello, this is Mia. When I woke up, I found myself trapped in a strange and terrifying place... I was surrounded by creepy monsters, unpleasant smells and strange sounds. But I have to get away from here. I have to be brave and take one step at a time.
 
...Will you help me?
 
Honestly, I don't know if you'll really answer my questions. But...there's this terrifying whisper in my head that I keep hearing. That whisper tells me that you will definitely help me. And Mia whispers to you some important information to help her along the way:
 
"It's your job to help Mia move forward.
 
But the road is very dangerous...many monsters are trying to attack her.
 
Even so, please don't give up.
 
With my help, Mia can see if the monsters have found her.
 
That information is projected directly onto her retina as a light like a line of sight.
 
I'm sure it will help you.
 
The fact that you've listened this far means that you're interested in helping Mia.
 
I'm going to tell you something very important...please listen carefully.
 
Mia will pass by...↓↓↓

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!

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!
