Yandere Grell x Male!Reader

Warning: yeah, there's more dicks.

Ever since Grell confronted you, her punishments grew even more harsh, threatening to make it worse if you kept resisting. Your body was constantly bruised, you could tell she was determined to break you, the fear of her slowly shaping you into what she wanted you to be. You noticed you flinch more often around her, growing increasingly nervous of her, but you still defied her whenever you could. As a result of this, humiliation started to become more prevalent, as she made you bow down to her and apologize (at first she said this sarcastically, then she actually made you do it) whenever you disobeyed. You tried to resist this once too, but it only got worse as she started to whip you if you displeased her. She even began threatening to keep you in the prison cell room, yet all her threats were later backed by her "I'm doing this because I love you" speech. She continued to supervise you and only give you menial tasks, as she "didn't want to overwork you." Today, she made you clean up and organize her closet, followed by cleaning the bathroom. While cleaning the closet, you remembered she kept her key in her coat pocket, but of course it couldn't be found. She knew better, she was hiding it from you, probably somewhere else in the house. You're always confused as to how it works, but you'll figure it out eventually. You both noticed the house was slowly being taken over by the stench of death, how the hell could she forget about William's fucking corpse in the other room?! You didn't dare bring it up to her, but she did eventually get rid of it, the one time she has ever left the room with you still awake. You jumped at the sudden noise of the bath water running, your head instinctively snapping over to the bathroom to see where the noise was coming from. Grell met your fearful expression with a sweet smile, chuckling at your actions. "Perhaps the smell of roses will help mask the stench of death, I'm just trying to make you more comfortable~" she looked back at the water running, then out of the corner of your eye you saw her expression turn to more annoyed, clearing her throat as an obvious cue to you, quickly catching on and muttering out a quick "thank you, madame." Her expression turned back to normal, smiling and testing the water as she said "you're welcome." She then shut the water off, standing up and stretching while calling back out "(y/n)~! My dear I need your help, come here please." You walked into the bathroom, shielding your eyes as she stripped down and got into the bathtub. "Aw, no need to be so shy, my love. I know you like it~. You may want to take off your shirt, it's humid in here. Since I've done this for you so many times, perhaps it's about time you return the favor and wash me up, isn't that right, sweetheart~?" You looked away, for once she did have an actual point that wasn't bullshit. She has washed you multiple times, on one occasion such you actually weren't capable of doing it yourself. So yeah, you did owe her at least one. "Yes mistre- I-I mean-" your eyes widened as you stumbled over your words, quickly clearing your throat and correcting yourself, "Yes, madame." Grell raised her eyebrow, her mouth curling into a smirk as she watched you quickly start to bathe her, moving quicker due to your embarrassment. "No, say it. If anything, I prefer it~" You looked down, staying silent as you washed her. In a quick movement, she grabbed your jaw, angling your head to make eye contact with her. "That was an order, my love. Say it. Now." You flinched but your reaction was late, your eyes darting around before meeting hers again and repeating yourself in the softest voice you could. "Yes, mistress." This was then followed by a sudden slap across your face, instantly whimpering and holding your cheek. "That's for disobeying me. I thought you knew better than that." She looked disappointed, but then relaxed as you started washing her again. Thankfully, you went through the rest of it in silence, avoiding looking at her as much as possible. As you finished up, she kissed your forehead, starting to drain the water before she stood up. "Good boy. Smells a bit better now, doesn't it? Anyway, I need you to do me another favor~" Her lips curled into a small smile, the one she gave you when- oh god, please don't tell me- "yes, madame?" You shakily forced out, only to receive another slap across your face. "That would be mistress now, sweetheart~. And in the nightstand on my side of the bed, there's something waiting for you. Put it on, I'll be out in a moment." You could already tell what direction this was going, but you could always hope for the best. Or, per usual, assume the worst was going to happen, as it was usually more accurate that way in this situation. "Yes, mistress." You didn't miss a beat with your response, fearing she'd get even more upset with you, going over to her nightstand and slowly, reluctantly, opening the drawer. As you had expected, assuming the worst was more accurate, as inside was a set of bright red lingerie, brand new and- "Grell, no, I'm not putting this on-" you were cut off by her slamming her fist into the doorway, standing with nothing but a towel wrapped around her body and her glasses resting on her nose. "Excuse me? What did I just hear?" Her tone was threatening, cutting into you like a knife as it struck fear in you, but you still continued to resist. "I-I don't want to-" you tried to speak, but she cut you off again as she yelled at you. "My darling, I thought you knew better, do NOT disobey me. You're mine, and you know exactly what will happen if you keep going like this, love~" she smirked, then her expression quickly changed back as she continued, "Now, would you like to try again~?" It seemed you had no other choice, she could easily just beat the hell out of you right now if she wanted to, then proceed to do what she wanted with you anyway. You slowly started to strip, feeling your face burn with shame as you put on the bright red thigh translucent highs, then replaced your comfortable boxers with the thin, laced underwear. "Good boy, now get on the bed, I've been waiting quite a while for this~" Her hips swayed as she walked towards the bed, and with great hesitation, without making eye contact, you mumbled out a small "yes, mistress", climbing on the bed to comply. She quickly joined you, taking the towel off and throwing it to the floor carelessly. You backed away, continuing to protest. "Grell, I don't want to-" you were cut off by her as she kept crawling closer to you, her lustful eyes locking with yours as you continued to move away. "Oh but you do, you know you do sweetheart~. I'm trying to be gentle, don't spoil this for yourself-" In the spur of the moment, the anger riled up from her response compelled you to slap her, unable to hold back as you yelled back at her; "NO, I DON'T. STOP IT." Grell drew back, shocked at your actions; her expression going through a cycle from her state of shock, to anger, then slowly back to lustful as she grabbed your jaw. "Looks like somebody needs to be taught a lesson~" Even with the flirtatious tone, you could hear her threat and immediately regretted what you did. She grabbed your wrists and reached over into the other nightstand, grabbing the rope and tying them together while you thrashed around, kicking at her which still held no effect. She then easily picked you up, slinging your body over her shoulder and carrying you into- oh hell no, that room. "Grell, please, anything but that room, anything but-" She ignored you and hung your hands above you on the hook, making you face the wall this time rather than her. She then stepped back, grabbed something from the floor, and in an instant you cried out in pain as you felt a sharp pain go through your back. However, it wasn't the whip like you expected, but rather it felt like a riding crop. "Let's just see how desperate you are to go back, hm~? Apologize to me and the whipping will cease, if you want to go back to the master bedroom," she chuckled, her face curling into the spot between your neck and shoulders, "you're going to have to beg for me~ Am I clear, sweetheart?" She whipped your back again, causing your body to jolt and you cried out in pain, still trying to resist it. She whipped you once more in the back, then once on your ass as she then snuck her hand around your abdomen, whipping you again as she made her way down to your shaft. She began rubbing it, stifling your grunts as she whipped you harder. Each lash became harder, tears now rolling down your cheeks as she continued. She drew her arm back, delivering one strike at seemingly full-force, causing you to finally break and tears to stream down your face. You cried out, apologizing to her profusely. "Mistress I'm sorry!! I'm so sorry please stop, I'm sorry!! Please get me down from here." You cried, flinching as you felt her wipe your tears away. "Now, now, if you want to go back to the bedroom you're going to have to beg for me~" She threw the riding crop to the floor as she kissed your neck, wrapping her arms around you and pressing her body against yours from behind. You complied easily, eager to be away from the horrid stench of death that still lingered in the room. "Please, I want to go back, I'm so sorry for hitting you, please just take me off this hook! Get me out of this room please it smells like death-" she let out a disappointed sigh, but still took your arms off the hook, slinging your body back over her shoulder and carrying you back. "Not exactly what I was going for, but good enough. I'll still get what I want." She closed the door to the master bedroom behind her, setting you down on the bed gently; face-down with a pillow between your legs. "Now, my love, I want you to really beg for me~. Tell me just how much you need me while you grind yourself against the pillow, my dear. Don't make me have to pry your mouth open, or we'll quickly be going back in there. And if you decide to cum on your own, well, that would be less than desirable for you~." Tears continued to stream down your face as she slapped your ass, indicating you should start. You mumbled out a small, pathetic "yes, mistress" as you rubbed your hips against the pillow. You emitted small grunts as you continued, your hormones kicking in and slowly forgetting she was even there as you became focused on your own pleasure. Regardless of the circumstance, it has been a while since you last felt pleasure. Your wrists tried to pull against the restraints as your member stiffened, grinding yourself hard against the pillow below you, hardly even thinking to control your noises. However, you were quickly snapped back to reality as you heard small moans from behind you; while you were focused on yourself, Grell had already pulled out the lube and was busy applying it to her member, stroking it as she watched you. Not being able to stop for a even a small moment without your member throbbing, you continued to grind yourself against the pillow. You kept going until you couldn't get any more pleasure from it, though your body ached for more, desperately dragging your member across the pillow for more. Without even thinking or processing them before they left your mouth, you half moaned out while still in your trance, "Mistress please, I need more, please, I need you! Fuck-" deciding she heard enough, you closed your eyes and your head hung down as you felt a cool liquid spread around your hole, then into it as she pushed two fingers inside you. You moaned out as she thrusted her fingers inside you, hearing her chuckle and tease you from behind. "Glad to see you're finally enjoying this, my love~." She then took her fingers out of you, slapping your ass once again before pressing the tip of her member against your hole, then pushing it in slowly as you gripped the sheets, moaning out as you felt your hole stretch around her. Grell did nothing to contain her moans, holding your hip with one hand as the other, still with some remaining lube on it, curled around your member and circled her thumb around the tip. She thrusted into you gently at first, then gradually began going faster while she stroked your member. As her pace quickened, you were quickly overwhelmed by the pleasure; feeling her member slide in and out of you and the near mind-numbing sensation of your member being stroked simultaneously. With one particularly hard thrust, you let out a louder moan, clearly being a cue to Grell to thrust harder as she had found your spot. She did nothing to stifle or in any way quiet her moans, only further advancing the trance you were in as she seemed to enjoy it just as much as you were. You felt your knees quickly go weak, the feeling spreading throughout your thighs and abdomen as you felt your climax approaching, your moans being Grell's guidelines as she thrusted harder. You struggled to find the words to tell her you were close, your mouth trying desperately to form them but all that could pour out was more moans. You quickly gave up trying to warn her as your body convulsed, semen squirting out from your member as your entire body went weak. Further prolonging your high, Grell's pace quickened again as she desperately tried to reach her climax, thrusting hard enough to leave bruises until she let out a long, rather loud moan as a warm liquid spread inside you. Your body convulsed again at this feeling while you felt Grell do the same from inside you, leaving herself in for a while as you both came down from your highs. "See, love? Isn't it better when you just- when you accept my love and submit to me?" She spoke between small moans, pulling her member out, clearly having enjoyed herself as much as you did. You couldn't focus on anything as the world around you spun, eventually slipping into a deep pleasure-induced sleep.
