All your clothes were either in the wash or in your own room, therefore you had absolutely nothing to wear for bed, nothing of yours anyway. You took one of Erwin's shirt out of his nightstand and lifted it up to your body admiring it, surely he wouldn't mind you wearing one of his shirts for the night. You placed it on the king-sized bed you and Erwin shared when you stayed in his quarters and jumped into his private shower to clean off the remnants of your day.
You welcomed the heat of the water as it splashed against your skin, and you wasted no time in lathering your body up with soap. You began humming your favourite song as you washed your body and hair, letting all the stress of your day melt away as the soap drifted down the drain. You sighed contently as you rinsed yourself off and hopped out of the shower, now fully clean. You wrapped the towel around your body and made your way back to the bedroom.
When you entered the bedroom, you were greeted with a waft of the cool summer air that came from the bedroom window you had left open while you went for a shower. You smiled to yourself as you dried your body off and threw Erwin's shirt on. It was little too big on you, the hem of the shirt hung just below your knees and the sleeves could act as gloves as you held them in your hands. You didn't mind it though, it was awfully comfortable and right now comfort is what you needed. You sprawled out on the bed and closed your eyes, waiting for Erwin to come home.
Erwin opened the door to his bedroom quietly. Usually you would have greeted him outside, but since you hadn't he assumed you were asleep, therefore he tried to be as silent as possible. Erwin turned his attention to the king-sized bed situated in the middle of the room and saw you curled up in a ball, sound asleep. He smiled and began to take off his Survey Corps uniform, stripping himself until he was just in his boxers. Then he turned his attention to you again, this time realising you were in one of his shirts. His throat went dry as the realisation hit him. He gulped.
Erwin had realised rather early on into your relationship that he had a size kink. One in which he was huge and you were, well, in comparison to him, tiny. The thought of you wearing his clothes had always turned him on and up until now, it had always just been a fantasy. You turned over in your sleep and opened your legs slightly revealing your exposed cunt to Erwin. He sighed shakily, trying to ignore the aching erection that was growing by the second at the sight of you. Not looking at the ground beneath him, Erwin moved closer to the bed to get a better look at you only to trip on one of his boots. He hit the ground with a hard smack but stood up quickly. The sound had you shoot up on the bed, fully awake and alert at the intruder.
"Erwin!" you cried out when your vision focused on him. "You scared the shit out of me!"
"Sorry my love," he chuckled. "I didn't mean to wake you up."
"I'm glad you did," you smiled softly at him. "I missed you today."
"I missed you too sweetheart," Erwin responded as he climbed onto the bed with you.
You sat on your knees and moved to kiss him, pressing your lips against his softly. You were swimming in his shirt as it covered your entire body and although there was no skin on show, Erwin couldn't help but feel his cock twitch in his boxers.
"How was your day?" you asked, pulling away from his lips and staring into his eyes.
"Long," he replied with a slight chuckle. "Very long."
"You're home now," you smiled pecking his lips once more. "It's good to have you home."
"It's good to be home," Erwin smiled at you, grabbing your hips and pulling you on top of his lap so you were straddling him.
You grinded against him slightly to get comfortable, but then you noticed his growing erection pressed against you. "Oh hello," you smirked, cocking an eyebrow and wrapping your arms around Erwin's neck.
"Sorry," he whispered, looking away from you. "You just look so good in my shirt."
You couldn't help but chuckle and chase his lips with your own. "I'm sorry for wearing it without asking," you said into his lips.
Erwin shook his head. "Don't worry sweetheart."
He kissed you once more, pulling you closer to his body. You couldn't help but grind against him once more as he did, earning an involuntary moan to escape Erwin's lips. You smirked devilishly and grinded down again, this time harder and slower. "Does that feel good, Erwin?" you asked teasingly. The huge man below you couldn't help but nod as you continued the motion.
You lifted Erwin's shirt you were wearing up, so it was bunched around your hips exposing your lower half to your boyfriend. Then you placed your pussy directly onto his bulge and began to grind again. "Baby," he whispered into your ear as you continued your movements. "I need to fuck you, now."
Before you were unable to say anything in response, Erwin had threw you off his lap and onto the bed so you were on your back. You couldn't help the giggle that escaped your lips as the giant climbed on top of you. Erwin pressed his lips against yours hungrily, thrusting his clothed cock against your folds. You let out a moan which was happily swallowed by Erwin's kiss and bucked your hips up in excitement. Erwin pulled away from your lips and looked down to see a wet patch on his boxers: his pre-cum mixed with your juices. He felt dizzy from the sight alone and his breathing intensified. You looked down to see what he was staring at and blushed, muttering a quick "sorry" beneath your breath. Erwin simply shook his head to dismiss your apology and attached his lips to your neck greedily. He began sucking and biting at the sensitive skin near your jugular vein, hard enough to leave marks in the morning. Erwin did love to mark you - it let everybody around know that you were his. You let out a gasp at the initial bite, your hands automatically flying to his hair and gripping tightly. You threw your head back and allowed him better access as he dipped a hand down to your pussy, stroking you with one finger.
"Oh baby," Erwin moaned between your neck when he felt the wetness between your legs. "You're soaking wet for me."
You hummed in response and nodded your head. Erwin continued kissing and biting at your neck as slipped one of his fingers inside of your core. You bit your lip and threw your head back as the initial stretch of his finger burned slightly. "Shit," you moaned out.
Erwin ignored your profanity and began to thrust his finger in and out of your cunt slowly. Occasionally, he would curl his finger inside of you, hitting the sweet spot that made your toes curl. Without warning, he inserted a second finger and you gasped loudly. Wasting no time, Erwin continued his movements inside you as he sucked on your neck. "'M going to mark you," he whispered huskily. You nodded enthusiastically, eyes half-lided with pleasure.
Just a few seconds later you felt your stomach clench, the muscles inside of you contracting as your release neared. "Erwin," you gasped out, eyes now wide. "I'm going to cum."
Erwin nodded against your neck before he pulled away to look you in the eyes. He was certainly a fan of watching you come undone. With a few more thrusts of his fingers, his name ripped from your throat as your legs began to shake violently beneath him. You weren't sure how it happened, but you found yourself squirting all over the bedsheets. You turned your head away from Erwin in embarrassment, but he used his free hand to bring your face back to him. His eyes were wide with lust and marvel. "Where did that come from?" he asked playfully with a smirk. You shook your head in uncertainty. Yes, he'd made you cum plenty of times before with both his fingers and his cock. But you'd never once squirted. "I liked it."
"Erwin, I need you to fuck me," you stated. Your chest rose and fell dramatically as you attempted to catch your breath.
"But before that," Erwin started, taking his fingers out of your cunt and placing them against your lips. "Taste how sweet you are for me, my good girl."
You nodded and opened your mouth wide enough for Erwin to slip his fingers in. You swirled your tongue around them, savouring the tangy taste of your release which coated them and stared directly into Erwin's eyes. Something about the lewdness and intimacy of it all had Erwin shivering with anticipation. He couldn't wait any longer. He pulled his fingers out of your mouth with a pop and pulled down his boxers, erection springing free of its restraints. Cock standing to attention, you marvelled at it. You reached your hands down to the hem Erwin's shirt, the one you were wearing, and went to pull it off in one swift motion but your boyfriend had other ideas.
"Keep it on," he said lowly. "I love the way it buries you."
You looked down at the shirt and nodded once more, a blush rising to your cheeks. In one swift movement, Erwin was hovering above you. His arms were on either side of your head as he towered over you. He bent down and captured your lips in a sweet kiss as he lined his cock up with your entrance, slicking his tip against your folds to cover it with your juices for lubrication. Erwin's eyes met yours and you nodded, signalling you were ready for him so, he pushed into you slowly. When he reached halfway, Erwin stopped and allowed you time to adjust to his length. You nodded again giving him the go-ahead and he pushed his remaining inches inside of you, completely bottoming out. Once he was fully sheathed, Erwin let out a groan of pleasure, one that erupted from his throat. Erwin closed his eyes for a second in an attempt to stop himself from cumming straight away. The feeling of your warm walls constricting around him was a feeling he had become addicted too, one that felt too good for him to even fathom during moments like this.
"Please Erwin," you begged, squirming beneath him. "Fuck me."
This was twice you had asked him, and twice you had asked so nicely. He didn't need to be told again. Erwin began rutting into you slowly, savouring the feeling. You let out a slight moan and Erwin picked up the pace. He bent down to kiss you, trailing down to your jaw and then to your neck where he continued his ruthless assault on your skin. With each thrust came a new bite or suck, one that would be sure to leave marks come the morning. He then turned to the other side of your neck, making sure to give each side an equal amount of attention.
"You feel so delectable around my cock Y/N," Erwin groaned. You wrapped your legs around his waist, pushing Erwin further inside of you. You both let out a moan as his cock reached a new depth inside of you. You scrunched your eyes shut and threw your head back in pleasure as Erwin picked up the pace, eager to please you.
"Fuck Erwin!" you cried out.
Erwin's eyes darkened and he moved away from your neck to look down at you. Through your closed eyes, you felt him shift his weight so he was balancing on one arm when you felt a sting on your cheek. He slapped you. Your eyes shot open and a silent moan fell from your lips as your eyes met his. "What's my name?" Erwin growled, returning his hand to the side of your head so he was balancing on both arms once more.
"Sir!" you called out, scrunching your eyes shut again. The pleasure began building up inside of you once more and there was no denying you were going to squirt again. "Sir, I'm cumming! I'm cumming!"
"Circle your clit," Erwin barked at you. You nodded enthusiastically and reached a hand down to your clit, circling the sensitive bundle of nerves quickly. You were desperate to feel that immense pleasure once more. Before you knew it, you reached your limit. Squirting all over Erwin's torso you let out an earth-shattering scream, one that the other members of the Survey Corps passing-by the Commanders room were bound to hear. But you didn't care and neither did your boyfriend. Erwin couldn't help but smirk as he felt your release drip down his stomach and pool at the bottom of his cock. You removed your hand away but Erwin stopped still inside of you, raising an eyebrow. "Did I say you could stop?"
"It's too much!" you cried out.
"I don't care," Erwin snapped. "Play with your fucking clit again."
You moaned and returned your fingers to your now sensitive, throbbing clit. "Too much sir."
"I'll show you too much," Erwin said, retracting his cock from your cunt. You whimpered at the empty feeling and propped yourself up on your elbows as you watched Erwin lean over to his bedside table. Your eyes widened when you realised what he was doing and you shivered in excitement. From the bedside table he pulled out a black vibrator, turning it on and staring at you with a devilish smirk on his lips. He pushed you back down again and attached the vibrator your clit. Almost immediately your legs began to shake and Erwin wasted no time in pushing his cock back inside of you, desperate to feel your warmth once more. "Hold it," he ordered, shoving the vibrator in your direction. You nodded languidly and took hold of the vibrator, keeping it pressed against your clit as Erwin returned his hands to either side of your head. His thrusts were careful, calculated, as he looked down at you. That damned shirt he thought. Erwin couldn't help but feel his heart swell at the sight before him. Your hair fanned out on the bed below, eyes scrunched up with pleasure and lips parted perfectly as a string of moans escaped them.
"Sir," you whimpered. "Too much! Too much!"
"Tell me what you want pretty girl," Erwin cooed against your neck, sucking at the marks that were forming. Tears began to stream from your eyes. The pleasure from his cock and the vibrator was too much and you felt yourself reaching yet another orgasm. Your legs shook and you were cumming before you could even warn Erwin. "Did you just cum again?" he asked.
"Yes," you croaked out. Erwin couldn't help but smirk as pride filled his chest. Only he could make you cum three times within the space of a few minutes.
"Tell me what you want," Erwin repeated. This time he sounded more serious.
"Want your cum," you cried out.
"You're such a good girl for me," Erwin smiled sweetly. Sweat threatened to spill from his brow as he continued his ruthless pace into you, now nearing his own orgasm. "I'm going to breed you now."
"Yes sir," you said hoarsely, turning the vibrator off and throwing it to one side to deal with later.
Erwin folded you easily into a mating press and began long, hard thrusts. Thrusts that were so strong, it sent shockwaves up your body. You ignored the dull ache in your body and just focused on the feeling of your boyfriend pounding into you at an ungodly speed. Erwin began to loose control, his thrusts becoming sloppy as he felt his own orgasm finally coming to a close. He wrapped his arms behind your head and brought you up to kiss him deeply as he shot ropes of his cum deep inside of you. He chanted your name like a prayer as he shivered before flopping down on top of you, his energy completely spent. "Wow," was all he could manage to get out.
"Wow indeed," you breathed deeply catching your own breath.
"Y/N," Erwin said, lifting his head up to admire the purple marks forming on either side of your neck.
"Yes Erwin?" you asked, smiling at him sweetly.
"And also, feel free to wear my shirts more often."
You couldn't help the hearty laugh that escaped your throat. If it meant having mind-blowing sex like that every time, then you most certainly would.
