Overview

【英語版】ママに内緒で姪っ子を"ぷにキュア"と騙して種付けする話 [ビュルルソフト]

《Raising Sim × Hands-On Training ADV × Incremental Mining》

Nanaha, the earnest and shy woman next door, drops by your apartment every afternoon on her own. What happens there stays between the two of you.

The core is reading her reactions: settle her bashfulness, hunt down the weak points on her body, and open her up one session at a time. Spanking and M-shaped open-leg poses are in there too, and at the end waits the "breeding," timed for her fertile days. Successful implantation unlocks a swollen belly and mother's milk.

Not swap-out art: this is "physics touch," where her breasts sway in real time to your hand and tongue, and every touch draws a different response.

Estimated play time: roughly 1 to 4 hours.


【Please check performance with the trial version before purchasing】
Real-time physics simulation may run slowly depending on your environment.

A Full-Blooded Incremental Mining Section

【英語版】ママに内緒で姪っ子を"ぷにキュア"と騙して種付けする話 [ビュルルソフト]

"Work" is no mere minigame. It is a genuine incremental progression system where you smash ore with your mouse to earn money and shards.
Attack power, crit rate, crit multiplier, and per-ore bonus damage all scale multiplicatively, and unlocked skills bring auto-attack and auto-collection for semi-idle play.
Basic stone → iron ore → volcanic stone → crystal ore → gold ore, all the way up to the enormous "Great Gold Nugget" that shows itself only rarely: hack-and-slash style satisfaction.
And the money and shards you earn become the funding for unlocking training menus and for Nanaha's rewards (items).
The stronger you get, the deeper the things you can do with her: two systems meshed into a single raising loop.

Main System: "H Training Mode"

【英語版】ママに内緒で姪っ子を"ぷにキュア"と騙して種付けする話 [ビュルルソフト]

- Switch between Hands and Licking; reactions keep flowing for as long as you drag♡ Thrusting is on drag control too, so the rhythm is yours. Several hand poses too.
- Sensitivity Shield: two random "weak points" every session. Find the right spot with the right method, break through, and her sensitivity is thrown wide open♡
- Bashfulness Gauge: rush her and it spikes; fill it and she pushes you away, ending the scene. Pat her head to calm her down first.
- Pleasure Gauge: fill it and she plunges into climax. Ahegao♡heart-shaped eyes♡squirting splash.
- Four positions: standing / kneeling / on her back / from behind.
- Five outfits, each with its own undressing sequence and expressions, plus extras like black knee socks♡
- Seductive Cat Dance & Cock-Teasing Dance: Nanaha swings her hips at you all on her own.

Ejaculation is never a swapped-in still frame; every last drop is dynamic, real-time staging.

- Where it lands is up to you. Her face, her breasts, her belly: take aim anywhere you like and drench her♡
- The splattered semen clings thickly to her skin and stays there, a lifelike depiction of thick, cloudy semen.
- While inside her, aiming and firing yourself or leaving it to automatic creampies is entirely under your control.

Plentiful Subsystems, and Conveniences Thought Out to the Last Detail

    - A schedule-based simulation where you raise both her Affection and her Lewdness.
    - Choose your actions each day and play your cards right so you never miss the evening "Nanaha time"♪

    Spend your earnings on a wide range of items: gifts that lift her mood, goods that heat her body up, stamina and virility recovery drinks, and more♪

    Sell the mining shards piled up in your bag for money; stamina and virility potions are there for the make-or-break moments too

    An observation notebook that quietly records everything the two of you have built up: creampie volume, touch count, even how many times she has climaxed

- Pool enough semen in her womb on a fertile day and she conceives on the spot. Pouring plenty in the night before works too♡
- Cross-section view: the moment it reaches her womb, and after implantation.
- Day count and condition during pregnancy show on the status screen.
- Rewards for successful insemination: the "Swollen Belly" skill to shift her into her pregnant form at will, and "Nanaha's Breast Milk" available daily after implantation.

# A Little Request From Byururu-chan

Illustrations, animation, programming……
Byururu-chan made every bit of it alone, with everything she had!

If the trial version wins you over, your support for the full version would make her so happy♡

She is still inexperienced, with plenty of places that fall short, so opinions and criticism are very welcome!

Progress goes up on X and Ci-en♪
