Synopsis
[Prologue]
You have a puppy.
A life created to be petted by humans.
A life bred by humans, created by humans, and managed by humans for a lifetime.
Is this really the right thing to do? I don’t know.
But this puppy was born to be loved.
Even if it was born to be loved and …… consumed, at least if it was loved.
If it were loved enough, from the bottom of heart,
I would see that as not a bad thing.
So let’s begin the test.
Your body is now connected to a special machine that I designed.
It holds your body in place and connects your feet to the pedals as well, which are connected to a giant spinning wheel.
You will have to keep pedaling.
No matter what happens…… no matter what happens!
Because when the pedal stops, your new family puppy will die.
But don’t worry.
I believe in you. I believe in a love from the bottom of your heart that overrides human karma.
I believe in your love. —- I believe in your love.
[Animation]
By incorporating an animation program into Unity,
we could create a smooth animation.
(Depending on the performance of your PC, the average frame rate is 60 per second.)
This gives a realistic impression of the thorough torment of the girl.
In particular, the girl’s behavior as she continues pedaling her bicycle and her movements when she is shamed.
You can see the realistic movements in the movie and the demo version.
[Hard Violent Sex]
The game goes to the extreme of shame.
Slaps, punches, uppercuts, kisses, cunnilingus, blowjobs (irrumatio)…

However, further torment is necessary to confirm the girl’s love.
You have to keep pedaling, to make sure the love…
Handjob, extra-thick vibrators, candles, pulling out anal beads,sex…
And electric shocks…
The girl screams and collapses as she pedals frantically…
And of course, don’t miss the screams!
The voice actor is Satsuki May.
Please enjoy the powerful voice of the girl.

There are parameters to see the girl’s condition.
Depending on the parameters, the girl’s situation will change.
It is up to you to make her live or die.

Editorial Review
This is a niche psychological endurance work that positions itself at the intersection of constraint simulation and moral choice—territory that demands either genuine thematic ambition or shock value to justify its premise. Bicycle Confinement Laboratory attempts the former: a scenario built on forced physical exertion that directly ties player agency to another being’s survival creates an inherent tension between bodily exhaustion and emotional obligation. The prologue’s deliberate philosophical framing—questioning whether coerced love can be authentic—suggests the developer understands they’re working with loaded psychological material rather than simply exploiting it.
What distinguishes this from standard endurance or punishment-themed adult games is the dual-protagonist dynamic implicit in the setup: your suffering is explicitly presented as an act of love rather than punishment for transgression, which reframes the appeal substantially. The animation implementation via Unity indicates attention to production quality, and the inclusion of voice and music suggests an attempt at atmospheric consistency rather than pure mechanical novelty. The English localization signals international market ambitions beyond the typical DLsite Japanese-language audience.
However, the synopsis cuts off mid-explanation, which itself is telling—whether accidentally or by design, this work seems to embrace opacity about its own mechanics and conclusion, possibly part of its aesthetic. That ambiguity will either intrigue players seeking experimental narrative design or frustrate those expecting clarity on what they’re actually signing up for.
This appeals specifically to players comfortable with philosophical discomfort alongside physical challenge, who value conceptual coherence in their extreme content and aren’t seeking traditional sexual gratification. The work prioritizes unease and moral vertigo over arousal.
A genuinely ambitious provocation that executes its premise with apparent seriousness—worthwhile for endurance and psychological simulation enthusiasts willing to sit with genuine discomfort.
