This was requested by: @_DhangerDhaddy_ , you better enjoy you fucking sinner.

You propped your feet up on the coffee table in front of you, satisfied that the pain killers had finally started to work, although the pain was still there, just a bit more tolerable. You hated getting your periods with a passion, but life was life, and life was a fucking bitch. The only thing that usually cheered you up during shark week was your boyfriend, Shuu, but he had some business stuff to attend today meaning you had to deal with cramps, cravings and soreness all by yourself. Like you said, life's a bitch.

You mindlessly flipped through the channels on the TV, wondering just when Shuu would be back, or if he would be back today. You hoped so. You really needed someone to brighten up your (crimson) day.

Hearing the door to your apartment open and close, you smiled brightly. "Hey, Shuu!"

"Bonjour, mi amore!" The man called back, although he didn't instantly show up in the living room. His trip to you took a few more seconds, leaving you puzzled as to why he'd hesitate at the door today.

Once he did appear in your field of view, however, he had a grin plastered on his face. "You surely smell good today." He said, eyeing you up and down a few times before his intense gaze went back to your eyes.

"That's maybe because I'm on my period." You sassily said, turning back to the TV. "Might smell good to you, but it's still an intolerable pain to me."

Shuu's lips fell at your words. "I'm sorry, chère. Is there anything I can do?" He asked, walking over to tug you out of your comfortable position on the couch and onto your feet. "Anything at all?" He questioned, a slight tinge of... Something else in his voice.

"For one, you didn't need to pull me out of my comfortable position on the couch." You retorted.

"Aren't you moody this time around?" Shuu teased, hands leaving your own to wrap around your waist and pull you closer to him. He nuzzled his face into your neck, taking a deep breath to inhale your scent. "I think I know what would help you out." He hummed before his lips kissed your jugular.

Getting a hint of what he was saying, you furrowed your eyebrows. "I'm on my period, Shuu."

Tsukiyama pulled away from you to give you the most filthy glance you had seen on his face in a good while. He did a once over of your body before his eyes landed on your lips. "Do you really think that's a bad thing?" He asked, subconsciously licking his own lips before his gaze went back to your eyes, a glint of lust shining in them.

"I promise I'll be good." He breathed before leaning forwards and crashing his lips on yours in a heated kiss. You slightly jumped at the intesnsity. Usually, Shuu was a passionate, gentle lover. He would take his sweet time with you and make sure to take things slowly. This lustful side of him was completely new, but you weren't complaining. You probably had your period to (thank) blame.

The man in front of you did not waste any time to pick you up by the thighs and lift you up, lips still moving feverishly against yours. You had no idea how he could still navigate through the house, but you weren't about to interrupt your kissing to ask him.

Once you were in what you assumed was your bedroom, Shuu dropped you on your bed, causing you to yelp when your back hit the soft mattress. The man above you simply chuckled before leaning over you and trailing open mouthed kisses on your jaw, and down the side of your neck. Once he arrived at the bottom of your throat, he pressed his tongue flat against it before dragging it up to your chin, humming in pleasure.

"You taste so good." He muttered before kissing his way down the other side of your neck while his hands trailed up your waist, causing your shirt to ride up.

"You know, I've learned to take that as a compliment now instead of a creepy, ghoulish remark." You shakily whispered, stopping his hands from going any further up by intertwining your fingers with his and placing his hands on each side of your head instead, making Shuu's smile of contentment turn into a frown.

"No matter how many times I've seen all of you, you're still insecure?" He asked, eyebrows furrowing in concern. "When will you see yourself the same way I see you?"

"You mean like a snack? Might take a while, Shuu." You sassed. You weren't trying to kill the mood, you'd happily go down on him if that's what he desired, but your stomach was bloated due to your periods, which meant that the stretch marks and scars there were more visible, and if those were more visible, they made the scars and stretch marks on your inner thighs visible as well. It wasn't a very pretty sight to you.

Shuu simply sighed. "You're not a 'snack'." He sternly said. "You're a beautiful individual, and honestly I couldn't imagine a better person to be this intimate with. I'll repeat it as many times as it takes for you to keep it in mind."

His hands slightly twitched in yours. "Now, can I..?" He asked, begging you with his eyes.

You sighed before slowly nodding, heart beating slightly faster when his hands let go of yours and went down to the hem of your shirt to pull it up. You sat up so he could take it off completely, before falling back heavily on the bed and keeping your eyes on the ceiling. He might like your body, but you still felt a bit uncomfortable about it.

"Hey, (Y/N), mon amour, look at me." Shuu demanded, smiling when your eyes went down to his. He pecked your abdomen, making sure to kiss and lick at every mark you had while his hands ghosted around your hips. All you could do was shudder at the pleasurable feelings he was giving you and watch. "I love you. All of you." He whispered before his face went lower and dangerously close to your crotch, inhaling the intoxicating scent your blood gave out.

"Are you sure you can control yourself?" You asked when his fingers started prying at the waistband of your pants.

"Positif. I wouldn't dare hurt the one I love." He seriously said. "And are you sure you want to do this?"

"Yeah." You breathed out.

That was all it took for Shuu to pull down your pants and slip them completely off your legs. His lust from earlier was back in full strength.

He briefly glanced up at you, searching for a bad reaction. Seeing none, he decided to take the last item of clothing off of you, smirking widely when he finally took in your naked sex.

His fingers trailed between your navel and pubic mound, causing you to shiver in pleasure. You felt your insides contract at the soft touch of Shuu's fingers and you basically felt the blood oozing out of you.

He couldn't wait anymore. Seeing the red liquid leak out of you was what did it for him. The man dipped his head between your legs and trailed his tongue on your inner thighs, gathering the sticky substance on his tongue and moaning out at the wonderful taste you left in his mouth. Thank goodness it was you, because if it wasn't, he would have taken a bite out of your inner thigh already.

You let out an unexpected moan when Shuu's mouth covered your lower lips, tongue darting through your folds to get as much blood as he possibly could. The fast and desperate pace he set made you completely forget about your cramps or your insecurities. You simply parted your legs wider and your hands found their way to Shuu's hair, gripping it like it was a lifeline, causing Shuu to let out a sinful groan that sent vibrations right to your core.

When you started rocking your hips against his mouth, Shuu couldn't ignore how uncomfortably tight his pants became and started (not so subtly) grinding his hips down on the mattress while his tongue kept skillfully lapping at you to get as much of your fluids as possible.

Your moans and groans mixed with his own as the pleasure he was giving you became almost unbearable. Your grip on his hair tightened even more and your legs pressed tightly against his head as you felt your climax near.

Shuu pressed his face even closer to your core, desperate to get every last drop of you. The results in his actions caused his nose to brush against your clitoris and the delicious friction was enough to send you over the edge.

Your back arched as you screamed out what would have been his name if your mind wasn't so focused on staying conscious at the moment. You gasped and panted as Shuu kept stimulating you until you had to push his head away, yelping at the painful overstimulation.

"Sorry." You breathed, chest heaving up and down as you tried to regain your breath. "I'm just really sensitive right now..."

You sat up, watching as Shuu panted and licked his lips. God, his disheveled hair made him look so much hotter than he already was...

Noticing your gaze, the male smiled innocently at you. "Thank you." He said before pulling a finger into his mouth and sucking it.

"You think we're done?" You asked, glancing down at the obvious bulge in his pants begging for attention. "Because I don't think we are. I need to repay you for the favour, no?"

"Only if you feel comfortable, mio caro." Shuu calmly said. "You did say that you were still a bit sensitive, after all. I'm satisfied with what I got, trust me."

"Yeah, no." You muttered, leaning forwards and keeping intense eye contact with your boyfriend. "You're not leaving this bedroom until you cum, Shuu Tsukiyama."

With that, you kissed him with such force that if he were human, you were sure you would have knocked off the bed and onto the floor. Luckily for you, he wasn't human and he was able to kiss you back with just as much passion.

You straddled his lap, slipping your tongue inside his mouth as your hands worked on the buttons of his shirt to free him of his clothes.

The two of you battled for dominance for a while until you gave up and let him inside your own mouth while you slipped his shirt off, hands trailing down his chest and abdomen, stopping at the waistband of his pants. You fumbled with his belt and the button on the garnement, making sure to get a few moans and groans out of him by 'accidentally' putting pressure on his erection.

Once you got rid of his pants and underwear, you broke the heated kiss and leaned away from him, causing Shuu to quietly whine at the loss of physical contact.

"I'm just getting a condom, don't worry." You said, laying flat on the bed to lazily reach your nightstand and open the drawer, looking for the square wrapper.

"We both tested negative though." Shuu stated, watching the way your body deliciously stretched and flexed while you were reaching for the condom.

"I know, but I still don't wanna risk it since there's blood." You explained, sitting back up and carefully tearing the wrapper open, smirking at Shuu. "That is, if you're still in the mood for this." You teased, giggling when your boyfriend gave you a glare.

"Do I not look in the mood right now?" He growled before grabbing the back of your head to pull you close. "Put the damn thing on me already. J'en ai assez d'attendre." He breathed against your skin, kissing and nipping at your neck

You complied and wrapped a hand around his dick, hiding your smirk when the man tensed up at your actions. He groaned out while you slowly rolled the condom on, teasing him as much as you could with the simple act.

Once it was on, Shuu pulled your upper body closer to him while you positioned yourself above him, resting your arms on his shoulders while his were gently lowering you on himself.

You both gasped once he was inside you. You kept sinking down until your hips met his and you nuzzled your face into his neck, already heavily breathing.

"Whenever you're ready." Shuu groaned out, trying his best not to give into his lust and flip you both over to go at his pace, which proved to be extremely difficult when you kept tightening up around him like you were.

You nodded, letting him know that you heard what he said loud and clear before starting to slowly grind down on him, shuddering. While you quickened your pace, you found the odd discomfort disappearing and soon a pleasurable feeling replaced it.

Shuu moaned out, his head falling into the crook of your neck while you quickened your pace furthermore, clinging to his neck while doing so. His arms found their way to your back, pulling you towards him so you were both chest to chest, the feeling only adding to the tension building up in your groin.

While you were moaning and groaning, Shuu muffled his own sounds by licking up the sweat that had started to coat your body, causing you to tighten around him once again. He couldn't last much longer like this...

Your back arched, a telltale sign that you were nearing your climax too. You were gasping for air and nearly screaming at this point, desperately slamming down on him to push yourself over the edge.

Shuu's hand slid from your waist to your abdomen, slowly trailing its way down where you both knew you needed it most. You leaned into his touch, keening when it finally found your clit, rubbing the sensitive nub to push you over the edge.

After ten seconds, you were screaming, your thighs were trembling and you tightened up around him, causing him to succumb to his own orgasm, groaning and lightly biting into your neck while he spilled into the condom.

Once the two of you had rode out your orgasms, you fell back heavily on the bed, slightly cringing at the odd feeling pulling out had given you. You glanced back at Shuu, who was carefully taking the condom off, eyeing the bloody thing.

"You are not licking the blood off of it when I'm here, Shuu." You warned. Sure, you knew he enjoyed it but there were limits to period sex and that was crossing one of them.

Shuu slightly pouted before tying off the latex condom and pushing himself out of the bed to throw it away in the bin while you simply looked around for your underwear before slipping it back on, not caring about still having the same slightly bloody pad in them. You just didn't want to have to change the bedsheets right now.

Satisfied with your solution, you climbed back in bed and made yourself comfortable, feeling the exhaustion of sex finally crashing onto you.

You felt the bed dip behind you and lazily turned around, flashing Shuu a small, tired smile.

"Is the pain a bit more tolerable?" He asked, lying on his side and lovingly tracing random patterns on your arm.

"Can't feel it anymore. Thanks. This was way better than taking painkillers." You admitted, kissing his nose.

"It was a pleasure." Your boyfriend hummed in response. "Quite literally, too."

"Ah, shush." You chuckled, placing an arm under your head. "I'm too tired for puns right now." You muttered.

"Right, right, désolé." He apologetically said before pulling you to his chest. "I'll let you rest now."

You snuggled closer to him, letting yourself fall into a well needed slumber.
