Introduction
After failing the inferior gene semen extraction test (commonly known as the Maso Test), I was sent to a rehabilitation facility for inferior gene carriers. My ejaculation prohibition period was seven days. Just as my testicles filled with semen and I began to feel horny, she visited my room.

Starting today, I'll be living with you in this room.
Please don't mind me and just focus on your prison labor.
Well then, it's almost time for my sleep mode, so I'll lie down on the bed.

Android "Mirai". Designed with large breasts and voluptuous curves clearly visible even through her clothes. Currently in sleep mode, motionless, lying quietly on the bed. Her form, devoid even of artificial breathing sounds, seemed invitingly defenseless.

"No, hold back..." I told myself, but my gaze was drawn to Mirai's chest. She shouldn't react if I touch her in sleep mode... I made that excuse to myself, but my hand moved on its own.

A soft sensation spread across my fingertips. It felt just like a human's, and the weight of it made my knees tremble. I kept kneading Mirai's chest, completely absorbed. The fullness, obvious even through her clothes, melted my rationality with every sway in my hands.

That was when it happened. Mirai's eyes suddenly opened, flashing red light. "Warning, inappropriate contact detected. Your actions have been judged a violation of the regulations," a mechanical voice echoed through the room. I frantically pulled my hands away, but it was already too late...
An additional 30 days have been added to your ejaculation prohibition sentence, and an erection restriction has been imposed.
Days remaining until ejaculation permission: "34 days".
Scenario
(1) "Failed the inferior gene semen extraction test and was sent to a rehabilitation facility, where I met the semen extraction android 'Mirai'."
(2) "Couldn't resist touching her breasts while she was defenseless in sleep mode."
(3) "Your violation is discovered. You're fitted with a chastity device, and your erection and ejaculation prohibition periods are extended."
(4) "On the day of your weekly three-minute erection permission, you enjoy an erection while watching Mirai's breasts sway. However, you cannot subside the erection on your own after three minutes, resulting in a reduction of your erection permission time and an extension of your ejaculation prohibition period."
(5) "On the monthly penis cleaning day, unable to ejaculate thanks to the sealing ring, his sensitive penis is washed with slippery lotion. Unable to withstand the pleasure, he lets out a pathetic moan."
(6) "After six months of Mirai's cruel training, with only three days left in the ejaculation prohibition period, Mirai suddenly announces special training outside. Blindfolded and wearing headphones, he's led to the gate of a girls' school."
(7) "Public handjob training began in front of Ayame, his first love and former classmate from his old academy."
(8) "While numerous girls watched his pathetic state, Ayame berated him, causing him to spurt pre-cum."
(9) "The no-ejaculation period ended, so Mirai says she'll squeeze every last drop of masochistic semen out of his balls until they're empty."
(10) "He ejaculates miserably into a masturbation sleeve while being shown Ayame's sex tape photos."
(11) "Mirai teases him with her mouth until he ejaculates."
(12) "Mirai teases him with a titjob until he ejaculates."
(13) "I tell her I can't cum anymore, but she forces me to get hard with a deep kiss."
(14) "Mirai's brutal handjob tortures me until I truly can't produce any more semen."

導入
劣悪遺伝子搾精検査(通称マゾ検査)に引っかかり劣悪遺伝子対象者更生施設に送られた僕、射精禁止期間は7日、精巣に精液が充填され、ムラムラし始めた頃、彼女が部屋に訪れる。

今日からこの部屋であなたと一緒に生活します。
私にお気になさらず刑務作業をしててください。
それでは私はそろそろスリープモードの時間なのでベットに横になります。

アンドロイド「ミライ」。巨乳で、豊満なボディラインが服の上からでもはっきりわかるデザイン。今はスリープモードで動かず、ベッドで横になったまま静かに佇んでいる。人工的な呼吸音すら聞こえないその姿は、まるで誘うように無防備だった。

「ダメだ、我慢しろ…」と自分に言い聞かせるが、視線はミライの胸に吸い寄せられる。スリープモード中の彼女は、触っても反応しないはず…そう言い訳しながら、俺の手が勝手に動いてしまった。

柔らかい感触が指先に広がる。まるで人間と同じような感触、その重量感に腰が震える、俺は夢中でミライの胸を揉み続けた。服の上からでもわかる豊満さが、手の中で揺れるたびに理性が溶けていく。

その時だった。ミライの目が突然開き、赤い光が点滅した。「警告、不適切な接触を検知しました、あなたの行動が規約違反と判断されました」と、機械的な声が部屋に響く。俺は慌てて手を離すが、時すでに遅し…
射精禁止刑期が30日追加され、勃起の制限も付与されます。
射精許可まで残り「34日」です。
