Work Text:
When Light had been released from imprisonment, after not being shot by her father and a bit of stretching, L started a new routine. A weekly dose of an experimental truth serum, followed by an interrogation. Most questions were procedural, concerning her wellbeing and general attitude. Standard, and identical every week.
Today, L had pulled up her sleeve, wiped over the back of her arm with something chilly, and then retrieved a needle from a cooler. She hissed at the pinch as L pushed in the plunger. Quickly, he disposed of the needle and bandaged the injection site. Light rolled down her sleeve.
“I don’t think your truth serum does all that much,” she quipped at him.
“Give it time,” L said. “It’s been shown to be very helpful in cases like this.”
How many cases like this have there been? Light wondered but didn’t ask.
“Now,” L took his usual position in the chair across the table. He adjusted his papers briefly and took up a pen. “How would you describe your overall life satisfaction?”
She rattled off a similar answer to every prior week. L made a note.
“How would you rate your attitude on life, encompassing hope for your future, your current daily level of pleasure, and ability to enjoy yourself on a scale of one to ten?”
Light, with nothing to hide and no reason to lie, told him the truth. “Seven.”
She almost missed the twitch on his face. His eyebrows and the corners of his mouth perked up for a fraction of a second before he scribbled down her answer.
“How satisfied would you say you are with your body and overall appearance?”
“Same as last week,” she was a little hesitant snow, voice scratching in her throat.
“Number it for me.”
“Seven.”
“Do you have ambitions to be much more than you are right now?”
“Doesn’t everyone?”
“Please keep your answers to a yes or no.”
“Yes.”
He didn’t bother to write that down. Nothing had changed, or would change on that front.
“Rate your level of sexual satisfaction, encompassing time with a partner or solo activities, ability to achieve orgasm when desired, and ability to manage your daily level of arousal on a sc—“
“Scale of one to ten with one being the worst and ten being the best,” she finished for him. “It’s very low, since by your own design I don’t get to have time with a partner or ‘solo time’, as you put it.”
“Your number, Light.”
She glared at him. “Three.”
“Hm. Do you feel as if the world is out to get you, or as if people you don’t know are plotting against you?”
The interrogation continued for another half hour before L’s final question.
“If you could change one thing about your life, what would it be?”
“I’d not be chained to you every day of my goddamn life.”
“So unusually aggressive, Light Yagami,” L noted. “I’m going to have you start a weight lifting program. It would be beneficial for your mind and body with the additional blood flow and muscle mass. It might also give release to some of your sexual frustration.“
“I’m not sexually frustrated!”
“Lying under truth serum? Quite impressive.”
In the following weeks, several things changed. Light, observant though she was, could not see what was happening to her own body. She woke up coughing several times, and attributed a slightly deeper voice to seasonal allergies. Baby fat dropped off her face and her torso’s shape shifted, because of the exercise L had her doing. She’d switched fully to tight sports bras, because her real bras seemed to always be at the dry cleaner, and what did she have to dress up for anyway? She was sweatier, but that was because L had control over the temperature in the building. He still injected her with a weekly dose of truth serum, and Light still answered all his questions, and he still religiously noted her responses.
Worst than all those changes, though, was that her sex drive had shot through the roof. That, obviously, was due to her inability to have time alone to masturbate. She’d not even got to touch herself in the shower, and was looking forward to the day she could refamiliarize herself with her vagina. In the meantime, she’d find herself grinding her clit down just a bit on her chair when no one was looking, squeezing her legs more often, and letting fantasies distract her from work.
There must have been some reality to L’s truth serum, because she’d rated her sexual satisfaction lower and lower, until finally it dipped to a zero.
L paused. “That’s not even on the scale.”
“I don’t care. You want the truth? It’s never been worse.”
He starred at her, assessing. She flushed under his gaze.
“Stand up,” he ordered. “I’m going to take your measurements again.”
She stood still, frustrated, emotionless, in front of him as he undressed her to her sports bra and boyshorts. He worked his way down with cold measuring tape and deft fingertips, measuring her neck, biceps, chest, and waist. He looped it over her hips and just barely avoided actually touching her ass.
“Spread your legs.”
She did. He knelt before her. His hands traced up from her knee to the thickest part of her thigh. The fabric tape pulled around her upper thigh, ever so close to her privates. On the other leg, the side of his hand accidentally brushed against her clothed genitals. She jumped back.
“I apologize,” L said, tonelessly. “Unfortunately, I do need you to remove your underwear for a last quick measurement.”
“Excuse me?”
He nodded seriously. “With the sexual issues you’re reporting, it could be a very vital indicator of health. You might need to see a reproductive doctor. I promise, I’ll refrain from touching.”
Blushing furiously, she exposed herself to L. He graciously held the tape measure a centimeter in front of her while he measured her clitoris.
He stood up and wrote something down while Light hastily re-covered herself.
“Do I need a doctor?” she asked.
“No. Everything seems fine.”
“But my issues—“
“Everything is as it should be.”
She glared. “How can you say that to me? With everything you’ve put me through.”
L approached slowly, eyes tracing over every inch of her body.
“Yes… I have put you through a lot, haven’t I? Too much, maybe. But Light… You see it too. You were made for something more than this, we both know that. I’ve been helping you along.”
It dawned on her there was something beyond what she knew.
“What did you to me?” Her voice cracked.
L smiled at her. “The truth is Light, from the moment I met you, I always thought you’d be a very good boy-toy.”
“You’re such a pervert! I’m not even a boy. Did you think you could make me one by what, lifting some weights?”
“Light… Making a boy of you was so much simpler than that.” He was right in her face but she didn’t cower.
“I’m not a boy.”
“Aren’t you?”
“I have a vagina,” even as she added extra snark to her tone, her heart sank with the truth.
“Mhm. A very nice one, too. But do you feel this?” His hand crept down and rubbed over the nub bulging beneath her underwear. Light shivered. “It’s grown. A whole inch. It’s trying to get big enough fuck someone. You’ve got to feed a growing boy, Light, otherwise he won’t get big and strong. That’s why you’ve been so horny.”
Light shoved him back. “What did you do to me?”
“I helped you.”
“What did you do to me?” Light asked again.
“Since treatment started, your well-being scores improved by four points. You feel better being a boy.”
“Tell me what you did to me!” He was near a shriek now.
“Just think about it. Light Yagami, a business man. A policeman. A well-respected professor who’s students giggle when they call you ‘sir.’ A future where you don’t have to spend every day pretending to be someone you’re not.”
Light reached out to strangle L but found him just out of reach.
“100 milligrams of testosterone administered subcutaneously every week,” L said quickly.
Light’s hands fell as the pieces clicked into place.
“Truth serum,” he breathed.
L nodded. “In many ways, it was. It revealed things you didn’t even know you were lying about. The truth is this: you’re becoming a man now, and you’ve never been happier.”
Light collapsed into his chair, stunned. L sat too, and took Light’s hand.
“I know it’s hard to believe, but the only score that worsened was sexual satisfaction. And I think that can be remedied quite quickly.”
Light looked at him skeptically.
“Should I remind you that every other choice I’ve made for you has been right? Trust me, Light. You need to get some relieve. I was a teenage boy once too, remember.”
“What should I do?” His voice shook more than cracked now.
“You’re really sensitive from all those hormones right now… I bet it wouldn’t take you long to orgasm just from, say, rubbing yourself on the corner of the table?”
Light was desperate enough to agree. Not yet comfortable with L’s gaze but too aroused to resist, he positioned himself with his weight on his wrists, letting the table’s ledge slot into his crotch, between his thighs. Slowly, he bucked against it. His eyes fluttered closed as he gave into the pleasure he’d been longing for. His hips worked quickly, pressuring building fast.
L, with cruelty, yanked on the chain that bound them, so that Light was suddenly trying to support his whole form with just one arm and couldn’t, pleasure point suddenly bearing the full weight of his body. He yelled out and quickly restored himself upright. He should have stopped and scolded L, but he was so close, so he held his body up letting his clit just brush back and forth against the wood of the table.
Dull waves of pleasure pulsed through him as he took shaky breaths. It wasn’t the world’s most satisfying orgasm, but he hadn’t felt this at ease in months.
L was stroking his dick. He’d watched.
“C’mere,” he said. Light approached with shaking legs. L peeled down his sticky boyshorts and pressed a finger into his puffy labia.
“You’re still getting wet, that’s good. I’ll get you creams and lubricants if that stops. And I’ll get you better underwear, schedule a surgery consultation—“ L prattled on about his plans to further Light’s transition while he fingered him. Light couldn’t pay attention at all to the intentions for his body because the pleasure was so right and grand. Just minutes after his last orgasms, L pulled a spray of fluids out from his new toy.
Light gasped with pleasure under his hands.
“Now, tell me the truth, Light. If you could change one thing about your life, what would it be?”
“Submit sooner.”
