A/N: Nothing's violent or gore. Just a modern day Vampire AU which doesn't involve castle or bat written for the following prompt received on Tumblr:

"Your blood tastes really good and I just want one sip but you refuse me".

The sound of glass shattering on the ground made Jellal stop wiping the wine glass in his hand to raise his head to see what had happened.

"Erza, you didn't get hurt, did you?" Lucy, one of the waitresses in the club, asked with concern as she went to Erza's side.

"Ugh, I cut my finger." Erza grabbed a napkin from a nearby table and wrapped it around her injured finger to try to stop the blood from bleeding from the wound. "Could you help me to clean the place while I treat my finger, Lucy?"

"Sure! But do you need any help?"

"No, thanks, I'll be fine."

"Okay, just call me if you need my help."Lucy said before going to find the broom.

And Jellal's eyes followed Erza until the woman disappeared behind the door to the staff room.

"Natsu." He called the other bartender.

"What's up?"

"I need to make a private call. Could you handle the bar alone for a moment?"

"Of course I can. We only have a few customers at this early hour." Natsu laughed. "Go."

"Thanks."

Put down the wine glass, Jellal went straight to the staff room. When he stepped inside, he found that Erza was in the middle of rinsing the wound with running water from the tap.

He locked the door before making his way to her side.

"Let me have a look." He turned off the tap and took Erza's hand in his to have a better look of the cut.

"It's just a minor cut." Erza looked up at him with a smile before giving him a kiss on the cheek.

They had been secretly dating for 4 months.

Just like Erza said, Jellal found that the cut wasn't too deep although blood was still mildly seeping out from the wound. Such a beautiful color. He mused and his eyes darkened as they fixated on the opening from where the red body liquid was slowly running out.

Pulling her hand to his lips, he licked away the drop of blood threatened to fall from her delicate finger.

"So this is the real reason why you come to see me?" Erza asked her boyfriend with a teasing tone while taking a gauze roll bandage from the first aid box using her good hand.

"I come to see you because I'm worry about your injury, dear." Smiling softly, Jellal explained. "I'm sorry. My instinct just kicks in when I see your blood."

Borned with human genes in his blood because there were several human ancestors in his vampire family tree, Jellal didn't have to rely on the consumption of blood to survive. But it was not like his lust for blood from his vampire origin had disappeared. It was just that he was able to suppress it most of the time. And when such lust was too strong to ignore at some days like when the moon was full, he would take animal's blood instead of human's. Although the amount of blood he needed wouldn't kill a human, he preferred avoiding the trouble of hypnotizing them into submission or taking the risk of having his true identity being discovered.

However, he broke his rule when he encountered Erza.

Taking the bandage from Erza, Jellal cut out a piece of several inches long from the the roll. Cautiously wrapping it around Erza's injured finger to cover the wound, he made sure that the force he applied wouldn't hurt her but was enough to secure the fabric on her finger. He was so focus on the work in his hands that he didn't even realize when Erza leaned toward him.

"My blood tastes good, huh?" She whispered seductively into his ear.

Jellal shivered feeling Erza's breath tickle his ear. Tying up the two ends of the bandage into a small knot, he turned his head slightly to at look Erza. He couldn't help himself from smirking when seeing the sly smile on her face.

"Heavenly." He answered in a husky voice before pressing his lips on hers.

Jellal still remembered that when Erza reported duty for her first night of work in the club, he already found that the sight of her deep red hair had somehow stirred up his desire to taste her blood. He was able to feed such desire with the alternative of animal's blood at the beginning. But when he realized that he had fallen for the human woman not only for her long skilly scarlet hair, pretty face and voluptuous figure, but more so for her kind, understanding, optimistic and confident personality, his lust to taste her blood grew stronger along with his love for her every day. And how Erza often flirted with him when they were alone certainly didn't help his self-control over his blood-lust nature either.

He finally lost it and gave in to the call of his primal need when she confessed to him.

Erza cupped Jellal's cheek with a hand to bring his face closer to deepen the kiss and wove her other hand in his blue locks. Circling her waist with both arms, Jellal pulled Erza into a tight embrace feeling her firm breasts on his toned chest. He sucked on her upper lip and took the chance to slip his tongue into her mouth when she let out a small moan. Her response to his invasion was eager, rubbing her tongue against his from every angle. He moved his mouth down to her jaw when she let go his tongue to take a breath, and he left a trail of wet kisses along her jawline and neck until his lips touched the juncture of her neck and right shoulder where he had marked her with his fangs several times before.

Needless to say, the first time Jellal sunk his fangs into Erza's flesh, which was just right after he kissed her in response to her confession admitting to her that he loved her too, she cried in surprise and in pain even he had bit her in the lightest way he could. Pushing him away, she touched the place where he hurt her and stared at him in shock after seeing her own blood on her hand. He immediately regretted for letting his impulse dominate his action, revealing his true nature to her too soon without giving her any warning in advance.

"I'm sorry." Jellal apologized sincerely. Sucking in some air he was ready to tell her the truth, praying that Erza would be just as forgiving and as accepting as his human ancestors were to someone from a different and allegedly dangerous species. But her words came out quicker than his. "You are a vampire, aren't you?" She spoke in a surprisingly calm voice and even wore a small smile on her lips, having already composed herself.

The evident answer to Erza's question stuck in Jellal's throat as it surprised him that she seemed to know his origin well and he shoot her a questioning gaze in return. "I know the kind of you from my dad. He was a specialist in supernatural creatures, and vampire was one of the main fields of his research."

They spent the remaining of the day talking and really got to know each other. "I'm not taking back my confession. If this kind of relationship had succeeded before, it can be worked out between us too. What do you say?" Erza asked Jellal shyly with a reddened face after they had spit out everything about themselves. His answer? It was an unwavering "Yes". They kissed for the second time that day, only in a more needy and passionate way than the first one and finally, Jellal was granted by his new girlfriend the right to have a sip of her blood for the first time.

It was the best blood he had ever tasted in his life.

Jellal licked the two red bite marks his fangs created on Erza's shoulder for drinking her blood eliciting a sigh from the redhead. Smirking from hearing her sound, he lowered his head further to placed small kisses along her collarbone from the unbuttoned opening of her shirt and slipped a hand under the hem of the same shirt to caress her smooth back. He grabbed a fist of her hair with his other hand and pulled lightly to make her head fell back to expose her throat to him.

"Jellal…" Erza moaned softly when Jellal brought his mouth to her throat and alternatively kissed and licked her. His mouth moved up and down her throat several times before reaching for her chin and left a kiss there. She held his face in both hands and pulled him in for another mouth to mouth kiss.

Enjoying Erza dominating the way they kissed to her liking, Jellal could feel not only his pulse quicken in his groin, but also his lust for her blood surge up. Sometimes he wondered if Erza had the power to awaken his deepest desires because unbeknownst to her, someone among her ancestors was also a supernatural being who had passed down their ability to her.

"Can I…...have one sip…...of your blood?" He mumbled between their kisses as his fangs slowly turned sharper and grew longer. He couldn't take her in the staff room when their colleagues were working outside, but he still wished to at least slake his thirst for her tasty blood.

He could feel Erza smile against his lips before she broke their kiss.

"No."

Jellal's face fell immediately.

"Isn't it a bit cruel for you to leave me hanging after arousing me with your kisses?" He asked with his baritone voice which Erza loved to try again and looked at her pleadingly.

Erza only giggled and kissed him on the tip of his nose before hovering her lips near his ear. "Come to my place after work."

Jellal couldn't help but grin hearing the alternate suggestion.

"That sounds promising."

Meanwhile in the bar, Natsu looked away from the staff room door with a frown on his forehead and looked for Lucy.

"Hey, Lucy."

"What's up, Natsu?"

"Do you think we should tell Erza that her moans were quite clear to hear when she made out with Jellal in the staff room because the door isn't really soundproofing?"

"Go ahead if you want to be killed by a very embarrassed Erza."
