About: you had one of those off-days and on top of that you are on your period. You decide to forget all of your problems and go to sleep, but the God of Mischief wouldn't let that happen and cheers you up. 

Warning: period sex 

It had been a long and dreadful day at the office and you were thankful to reach Stark Tower by the end of the evening. New deadlines had been fired at you through the day and it had you stressed and on edge for the majority of the day. Your emotions were all over the place, you were irritation by your collegues forcing everything in your hands and the way they threated you. 

And it didn't help that your period just started. 

As the moon took the place of the sun, you clicked your keys in the key hole and flicked the lock, clumsily getting into your room and making your way towards your small bedroom. 

You dropped all of your belongings at the door and padded over to your bed that looked especially heavenly after a long day. You sighed, briefly closed your eyes and peeled off your jacket. 

You pulled the covers of your bed back and went to your small, but sufficiant bathroom. You quickly singled out a few towels out of the closet and brought them with you to spread them out on your bed. 

You sighed once again, admiring your handy-work with tired eyes. With a convincing nod, you unbuttoned your jeans and slid them off your lean legs, taking your black lace underwear with it. The same goes for your shirt and bra, now discarded on the wooden floor of your bedroom. 

Your hand searched between your thighs to the thin thread as you pulled out the tampon and quickly threw it in the bin next to your desk. All you wanted to do was forget about this awful day, your co-workers, the terrible cramps and go to sleep. 

While crawling into bed, you undid the ponytail in your hear and put the elastic on your nightstand, taking the covers with you and falling back against the mattress. The cool fabric welcomed you and clung against your naked body. 

Your eyes closed and you swiftly drifted off to sleep. 

A flick on the lock made you eyes flutter, but you were simply too tired to acknowledge the sound, so you turned and rested on your stomach, face firmly planted into a pillow. 

Drifting away from the world again, you lay peacefully, until the bed dipped. 

You moaned, cursing the intruder, forgetting how less you wore when the figure straddled you from behind, slowly putting all of his delicious weight on you. Strong muscular arms snaked around your waist and raged breathing filled your ear. 

But it was the hardness pressing between your legs that alerted you. Eyes snapping open you looked over you shoulder and a smug pair of emerald eyes met your panicked gaze. 

What was he doing here now? Your thoughts wandered off to the bloody mess between your legs and you swallowed nervously. Hesitant about your next words, or how you were supposed to greet the man, he made the first step. 

"Hello again," he drawled in that midnight purr. You wanted to melt, but stopped yourself. Stop it, YN, you scolded yourself. No sex tonight. You're on your period. 

"L-Loki?" you squeacked, trying to close your legs,but his knees prevented that from happening, they were firmly pressed between your legs, exposing you. Your hearbeat sped up, as well as your breathing. His lips brushed against the shell of your ear, tongue teasingly flicking across the skin before nipping at the lobe. You sighed, eyes falling closed. You relaxed into the mattress as he tangled a hand in your hair, pressing you down. 

"Why are you here?" you asked, trying to ignore how his hand ran down your spine, making it feel so good. You shivered. He chuckled darkly in your hair, his hand coming to a halt just above your ass. 

"Why not?" he replied smugly, a grin curling against your bare shoulder. You bit your lip. His voice was getting hotter by the second, and something between your legs harder. 

This was so wrong.  

"You're always barging in on the wrong occasion," you said, defeated. You felt yourself willing to succumb to his dalliance. His hand sneaked under your chest, cupping your breast and teasing the nipple. You squirmed, biting your lip to keep the moan from rolling off your tongue. 

"I disagree. I thoroughly enjoy our encounters. And you, do too," he said, smirking against your neck, nipping at the spot. "Especially the times when I catch you in the shower." A blush dusted your cheeks. 

Oh, yes, how you reminded how he fucked you against the showerwall. You moaned as he grinded into you, but snapped back to reality as you realized the state you were in. Altough you were quite certain of what his answer was going to be, you decided to ask it anyway. 

"Why are you here?" 

"Ehehe," he laughed against your jaw, making you writh beneath him. "Because if you are on your period, all the towels in the bathroom suddenly disappear." He cupped your cheek rather hard then. "And I intend to fuck you." 

Normally, you would be all for it. Sex with him was devine. 

Before you could utter a word, he forced his thumb between your lips, caressing your tongue, and as on insitinct you started sucking. He moaned. His other hand took yours and brought it above your head, fingers entwining with yours. He withdrew his thumb. Your heart sped up, the flame in your stomach growing. 

"Loki." 

He immediately stopped, popped himself up on his elbows and pushed a few strands of hair out of your face. His worried gaze met yours. 

"What's wrong?" he whispered. You adverted your gaze, the blush worsening. 

"I'm on my period," you repeated his former words. "Its's going to be- It's going to be messy and-" He interrupted you by placing a kiss on the top of your head. 

"If it were to make you less uncomfortable, making love to you while you're on your period is one of my many fantasies. And I don't mind things getting messy." He gave a slight chuckle, that tightened the coil in your stomach. "We can jump into the shower together right after." Truth to be told, you really wanted him now, and he knew it. "Turn around, darling." 

You licked your lips, doing as he told you. 

Your eyes met, and a part of the uncertainty left your body, replaced by something else. His hand went to caress your face, tracing the bridge of your nose before he pressed a kiss to your temple. 

His mouth placed kissed on the corners of yours, before descending on your lips, taking them in a heated kiss that made you moan. You hooked your arms around his neck, wanting to feel him closer, and all you could think about, was him. 

You needed him, now. 

The coil in your stomach tightened uncomfortably, begging for release. You squeaked as he bit your bottom lip, nipping down at the delicate skin and then sucking on it, giving it a flick of his tongue before his hand disappeared between your bodies. His skilled fingers played you masterfully, toyed with your nipples until they become a rosy shade. Bending down he plastered kisses all over your chest, dragging his tongue along your breasts, biting down softly every now and then before he grasped your hips firmly, halting all movement. 

You moaned out in frustration, glaring at him in the leftovers of the evening sun. 

You were met by a smug facial expression. His hands loosened around your hips and you frowned. 

"Loki, I swear to God if you stop now-" His nails dug into your waist, pulling you against his hardness it rubbing heavenly against your heated, dripping core. 

He groaned, eyes leaving your face and focussing on the ornament between your legs. The tip of his cock sank into you wetness and you squeaked, hands gripping at his upper arms, back arching. The peculiar sensitivity already had you squirming in his grasp. You closed your eyes in ecstasy, biting your lower lip and thusting your hips forward. 

He groaned, head rolling back, but eyes focused on your core firmly squeezing around his cock. 

"Look at it," he rasped. "Look at us." He grasped your chin, your eyes landing on your joined bodies, watching wide-eyed how his cock slipped free from your pussy, glistening in your wetness and blood. A blush dusted on your cheeks. "Don't be embarressed, it feels so good." His voice strained, and he leaned in to kiss you, his tongue dipping in your mouth as he thrusted inside you to the hilt. 

You screamed against his mouth, the feeling in your stomach untamable at this point. 

Your hands roamed his naked back and you intentially dragged your nails across it, knowing he liked it, especially when he groaned in your ear, hitting a deeper spot inside you that made you arch against him. 

Keening lewdly, you placed a hand on the side of his face, placing kisses on his razor sharp jaw as he continued to thrust as a excrutiatingly slow pace, circling his hips so his pubic bone served as a blow to your clit. 

One of his hands tangled in your hair, forcing you to face him. His face contorted with pleasure, and his lips desperatly searched for yours, as if you were the only medicine that could cure this mad bliss. 

Breath growing raged, he picked up his pace, tearing his lips from yours and placing his forehead on top of yours. 

"I'm so fortuitous that you are my girlfriend, God, I love you, Y/N," he moaned, thrusting into you while gritting his teeth, taking your hand in his and pinning it to the mattress above your head. Your heart did a silly flip, a welcoming warmth spread inside your tummy. You inhaled shakily, wrapping his legs around him, heels digging into his ass, wanting to pull him closer. 

He had you wrapped around his finger, winding you tight, until you snapped. You screamed his name, back arching and you core gripping on his lenght. He moaned sensing you were close. If it were possible, he fastened his pace even more, sending you over the edge. Your head rolled back and you moaned out his name, kissing his neck. 

His hot seed spilled inside you just as you reached your peak and you clenched around him, wanting each drup inside you. His ragged breath filled your ear as his hand pressed against your cheek to caress it. He pressed a soft, caring kiss on your cheek before rolling off you, face facing the ceiling as he lay next to you, the both of you catching your breath. 

He took your hand, his thumb stroking your knuckles. A grin spread across your face and you faced him with a toothy smile. You didn't care if you looked silly. Your heart fluttered as you looked at him, smiling back at you with a questioning look on his face. 

"What?" he chuckled. You shrugged, rolling over so you laid flat against him. You bit your lip. 

"Am I your girlfriend?" you asked, trying to hide the excitement in your voice. "Do you love me?" Hope spread in your chest, accompanied with the warmth in your tummy. He licked his lips, the smile leaving his lips as he went to scratch the back of his neck. 

"I - I - yes, I love you. Are you, are you not my girlfriend?" he asked, his voice growing more silent with every word he spoke. You smiled, your fingers fondling his cheek. 

"You never mentioned it." Your eyes met his emerald ones. "But I honestly like the sound of that. And I love you too." Your pulse raged through your veins, anticipating his answer. The nerves slowed down as he smirk up at you. 

"Alright, that's settled then. You're my girlfriend. I'm yours, you're mine." He placed a hand on your shoulder, dropping it again to caress your arm, zoning out while staring at you. You admired his beauty, those sharp facial features, those eyes -

He snapped out of it, a sly grin tugging at the corner of his mouth. 

"Now, if I'm correct, I promised to clean you up in the shower?" Your grin mirrored his, you got up and pulled him up from the bed, the both of you hurrying towards the shower, chuckling like two puppies, madly in love.
