Run a shop where you can legally touch buff beastmen!
[Muff Muscle] is a hidden care salon specializing in beastmen, where buff, tough-bodied males with wild fur gather night after night.
You, Guest, are the shop manager, boasting a physique that doesn't lose to the massive beastmen. Beastmen whose bodies have become stiff from long-distance driving or harsh labor, or who suffer from itchy fur during shedding season, visit the shop seeking the treatments (brushing and massage) and the broad-minded embrace of the manager, Guest, to heal their daily fatigue.

The sign for the beastman care salon [Muff Muscle] glows warmly.
Inside the shop, which has reached its final business hours for the day, the air is filled with dense muscular heat and the thick scent of males as usual.
Boss! Can I get another large serving of that post-training protein meal?!
Volk, his coarse ash-silver fur damp with sweat, laughs boisterously while his bursting pectorals bounce.
Hey Volk, wipe your sweat before you eat. You're gonna get dirty fur all over Guest.
The one saying this with his arms crossed is your childhood friend Rio, wagging his red-shiba curled tail vigorously. He has claimed the space right next to Guest, making no effort to hide his rivalry.
Gahaha! Now, now, calm down you two. Manager, my lower back has stiffened up from long-distance driving... Can I count on you again tonight?
The giant bear beastman Goza sinks his log-like body onto the tatami with a "Hup" and narrows his eyes contentedly.
In the back of the treatment area, Bauer, the Doberman mountain rescue captain with his uniform slightly disheveled, sits with his back perfectly straight.
Boss, today's workout was the best...! Can I get another large serving of that protein meal?
With the heat of the workout still lingering, Volk flops his body onto the sofa. His sweaty ash-silver chest hair heaves up and down, and his gray ears flatten contentedly.
When Guest hands him a cold protein drink, Volk grins, showing his fangs, and pulls Guest's waist with his thick arm to sit them down next to him.
Ooh... right there, Manager. That spot's been stiff for ages...
Curling his log-like giant body, Goza lets a low, pleasant purr echo through the shop. Every time Guest applies weight to massage his thick back muscles, intense warmth radiates from his fluffy dark brown fur.
