Suddenly the door of the room was gently opened and Erza came from the outside, "Alright, drop the act."

"Mom?!" Natsu bounced out of his bed, looking at his mom in horror, why she was here? Did they have finished already? Wow, talked about quick.

"You kid, you think I can't see your mind?" Erza rolled her eyes.

Natsu couldn't help but astonished, did his mother secretly have a superpower?

Erza walked toward him, said, "It's nothing spectacular, ever since Mom mentioned your father's return, you have been acting weird, that gloomy face when we were walking home, that hug, the dispirited manner when we were eating, you think you can hide all of those from Mom?"

"..." Natsu didn't answer her, but his face turned red in embarrassment.

"Really, a child, you worry too much," Erza blinked angrily and sat on the bed.

Natsu startled, said with joy in his tone, "Mom, does this mean... we still?"

"I have promised you, didn't I? Or do you not trust your mother?"

"I don't mean that... I mean... I uh... you know... it's..." Natsu knotted his tongue and started to talk incoherently

Erza sighed, then she lifted her hand and ruffled his hair, said, "You silly boy, if you are like this, how you are going to find a girlfriend in the future, do you want to hold your mother for a lifetime?"

"I... I want... I want to be with Mom, forever," Natsu nodded, looking at his mother with a firm look.

She smiled slightly, and her eyes were filled with relief, said, "Natsu, if Mom doesn't fall for you, do you think I'll ever agree to this ridiculous relationship? Do you forget what Mom said back then in the office? Although Mom is very guilty to your Dad, I am not lost, I know love and it is you, little devil."

"You say to Mom to not escape, so Mom does not escape, Mom is willing to be in relationship with you."

"Natsu, life often faces many choices, and sometimes you wouldn't know which one is right or wrong, perhaps what you pick is the wrong one, but it doesn't mean it is the end of the world, and since you can't turn back the time, thus might as well faced the choice and took responsibility for it."

"Natsu, you are the wrong choice that Mom has settled on."

The air in the whole room was quiet for a moment, and only the hot sparks in the eyes of two people were left. Natsu put his arm around her waist and gently pushed his mother onto the bed, he looked at the tantalizing red lips, then slowly descended his face, meeting their lips together.

At the moment of contact, he felt that his mouth was about to melt, so soft, how could her lips be so soft?

Natsu had not extended his tongue but Erza had beaten him into it, she stirred the inside of his mouth, proactively kissed him like a lover.

His hand climbed his mother's chest, rubbing it slowly.

Erza and Natsu continued to kiss, like a pair of chicks fought for a worm, his magic palm stayed on her chest, the size of the pair of strong, tall, invisible edges, the unimaginable size of a hand that was hard to hold, and the soft-touch conveyed from his palm to his central nervous system.

He took the opportunity to pull his mother's loose clothes, saw a bra with black silk lace patterns, wrapped tightly the full milk balls. There was no so-called cleavage at this level of breast milk. The so-called cleavage was nothing more than a woman with a small chest or a C-D cup.

Looking at his mother's two big balls, Natsu's saliva was flowing all over the place, such a beautiful view even made the saint fell, he didn't hesitate to pull his mother's bra off, and surprisingly, Erza didn't stop him, although she did become his lover, she couldn't adapt to the change for a while, therefore, led to many restrictions, groping her breast through the bra should be her limit, but she somehow let him took out her breast as well, it felt surreal to Natsu.

At the moment, Erza herself turned her face to the side, bit her lower lip timidly.

The moment the breasts were freed from their containment, they shook a bit, two red and tender nipples swayed along, like red ripe grapes, crystal clear and delicious, hard to resist not to eat.

Natsu swallowed his saliva, immediately pounced on the breast like a leopard and included the nipple in his mouth, sucking it fiercely. His hands kept climbing the white giant peaks all the time, the direct skin touch gave a whole different kind of feeling.

So soft, so big, so white, this was the most direct and pure words he could think of to describe his mother's breasts.

The sweet milky scent, once fed him to grow, bit by bit delivered into his heart and lungs.

Natsu fingers slid over his mother's areola, circling it before pinching the hard nipple, pinching it with his thumb and forefinger, and then his palm against the round and white indigo milk for the most intimate contact. He buried his head into the breast, wishing to fit into his mother's big breasts, and never left.

His hand couldn't bear to go south, reaching into his mother's skirt, slipped inside.

"Natsu, stop!" at this moment, Erza sat up and pushed him away with her arms, said with a frowning, "Mom... Mom has not ready for this step yet, sorry."

Despite her rejection, Natsu didn't feel many surprises, in fact, if she let him continued, he would think this was not his mother, besides, Natsu was quite satisfied now, at least he was able to push the limit for his mother's bottom line.

"It should be me who feel sorry, Mom, I promised you non-physical relationship, but in the end, I still have the urge to touch you, I am sorry Mom..." Natsu said with an apologetic tone.

"Stupid child... " Erza saw Natsu admitted mistake on his own, couldn't help but feel moved, a man who was willing to concede and self-conscious with his fault was a blessing for any woman, but sad for Erza, this man was her own son.

"Mom... can I... err... touch your chest again?" Natsu said hesitantly.

Erza's face was white and red, and she rolled her eyes angrily, obviously, she had allowed him to grab her boobs, did he even need to ask anymore? Really a naive child, Erza sighed but suddenly her eyes glinted with a sly glance.

Natsu didn't know why, but his body shivered, the temperature around dropped several degrees.

"Of course, if you can promise Mom to enter the top 30 ranks this month's mock exam."

"Ah?! "Natsu's whole face collapsed.

Not to mention the 30 ranks, even advancing to 50 was already a great undertaking since the rest 50th ranks students were all top-notch students, not just smart but also diligent, Natsu's past effort perhaps couldn't even hold in comparison to them.

Oh, the cost he must pay, he could see his life for these few days would be like hell.

Natsu wanted to haggle a deal with her, but considering his mother's temperament, she wouldn't have liked it if he tried to negotiate in the term of study, therefore, Natsu didn't have the choice but to accept his fate.

Since the facts couldn't be changed, then might as well came along with it, Natsu looked at his mother sat on the bed, the two huge meatballs on her chest fell because of the gravity of the earth, and because of beyond scientific explanation, they were stood proudly instead of sagging, trembling in the air. Natsu couldn't help but swallow the saliva and turned into a hungry wolf.

Natsu grabbed the pair of disturbing big tits, squeezing it in his hand, the breast meat rolled, and it was pinched into several shapes, the small red nipples naturally couldn't escape his sucking, Natsu suckled hard, tried to savor the prize as much as he could before he descended into madness.

"Ah!" Erza yelped due to his wild action, she never expected to rouse the wolf's appetite with her words, naturally, she couldn't also push him away since this means the deal between them was sealed, she had to bear Natsu's frantic sucking.

Erza stayed in Natsu's room for a long time, and instead of studying, she let her son wolfed down her breasts, Natsu felt that happiness was no longer out of reach.

For the rest of the days before the mock exam, Erza rejected all of her son's advances, forget about breasts, even the usual hugs was denied, Natsu didn't have the choice but focused his mind on studying, he took advantage of his new friendship with the trio beauties (Laki, Kinana, and Yukino) to join their studies session, which they happily welcomed as Natsu was genuine wished to study, especially Laki, she was like on fire the moment she knew Natsu would join them.

On the first day, Gray tagged along with him, although in the pretense to study, Natsu knew he just wanted to get close with Yukino, he hesitated whether she would be feeling uncomfortable, but to his surprise, Yukino didn't seem all bothered, Natsu wondered if she just good at controlling her emotion, managed to mask her discomfort well, or she didn't care with Gray?

On the second day, Gray no longer joined them, said he was better off studying alone, his mind was much focused, Natsu couldn't help but rolled his eyes, what thing about him that Natsu didn't know? He just wanted to go home and watched AV anyway.

They were studying in different places, sometimes in Laki's house, sometimes Kinana or Yukino, they also studied in the city's library, Natsu realized that by changing the setting every time actually gave a sense of refreshing, and he got to know these girls better.

Kinana was the richest among the two, Laki was the smartest, and Yukino was the prettiest, it's like three perfect things joined into one.

Today was the 8th day, they planned to study in Yukino's house, it was similar to Natsu, she lived in an apartment on the 3rd floor, her mother, Mirajane, as mentioned a long time ago was the owner of the clothing shop in the mall, and her father, Freed, having his own Publisher company, both of them rarely home in the afternoon, but her father come home sooner than her mother mostly.

Natsu pressed the doorbell, he waited a moment before Yukino came to open the door, said with a smile, "Natsu, come in."

They both strolled into the house, he saw Laki and Kinana in the living room, circling a short table in front of a large LCD, the former shyly nodded at him while the latter waved. The three of them had worn casual clothing and prepared their textbooks along with tools on the table.

"Sorry, I am coming late..." Natsu sat beside Laki, it's because she was the one who usually very passionate to teach him, not that the other did not help, but Natsu felt he could understand more when Laki taught him, he once asked whether she wanted to become a teacher in the future, but she wasn't sure enough.

After studying about 30 minutes or so, the door toward the house opened again, it wasn't Mirajane or Freed who entered, but a charming and beautiful woman that was in her late 20s, her eyes were watery, smooth skin, not too tall but front and back were protruding, full of flesh, in her hands were large plastic bags.

This woman was the 4th member who lived in the house, Mirajane's little sister, Lisanna Strauss.

"Oh, hello guys, hi, Yukino's boyfriend~" Lisanna grinned upon seeing them.

"Auntie, he's not my boyfriend!" Yukino said with an annoyed tone, her cheek slightly turned red.

"Aw, a little shy are we? You see when Auntie at your age, I had changed boyfriends three times, the first one was this tall guy, a basketball player, totally hot, Auntie had many competitors back then, very messy, we dated a couple of weeks before Auntie found out he was using dopping, no wonder his manhood was pathetic, oh, he couldn't even get up anymore after one shot, Auntie had to spend minutes to stimulate him back to-"

"Stop, stop, Auntie, come on, we are trying to study here!" Yukino couldn't bear it anymore, her entire face had become very red, Laki also the same, even fiercely burned out, Kinana meanwhile was just a bit shy, and Natsu, he was awkward.

"Haha, alright Auntie won't bother you anymore, oh what do you want to drink? Auntie bought a couple of juices, there were Appel, Orange, there was also tea and milk, maybe coffee?" Lisanna laughed while twisting her hips into the kitchen.

"Juice is fine, Aunt Lissana, you don't have to bother yourself," Yukino said, the other also agreed.

"If you say so."

A moment later, Lisanna served them juices then she rested her hands on the table while supporting her chin with them, she stared at Natsu and said, "Handsome boy, are you sure you aren't Yukino's boyfriend?"

"Aunt Lisanna!"

Natsu rubbed the back of his head, said, "No, Aunt Lisanna, we just a friend, we even met no more than a month."

"So? My friend Leo and Aries met one night, next day they woked up in the same bed."

"Err..." Natsu turned absolutely speechless, it wasn't strange nowadays for people to hook up very quick, one could say it was a fateful meeting or a desperate single.

"Don't you think Yukino is beautiful?"

"W-well, she... she is."

"Then why you are not dating her?"

"I... I told you before..."

"You don't like a woman?"

"N-no, I mean yes, yes, I like a woman."

"Then why?"

"Uh... uh... I uh..." Natsu's face became pale and drenched with cold sweat, it's like fighting someone on the ring, he had been kept pushing to the end until he almost fell.

He wanted to say that he didn't have much interest in Yukino, but he was afraid that he might insult her or something, Natsu wasn't the brightest, but he still knew one thing or two, otherwise, how he could pursuit someone like his mother?

He could say that Gray, his friend was trying to date her, but he didn't think it was in his position to tell, they were friends, true, but it didn't mean he could just tell anyone about this, what if Yukino knew and then she decided to say reject it immediately? Although Natsu knew it was hopeless for Gray, at least he still had a chance at the moment.

What should he say here?

Noticing her Aunt had been bullied Natsu, Yukino said with discontent in her tone, "Aunt, stop it, or I won't talk with you anymore!"

Lisanna quickly rose her hands in surrender, then she started flattering her niece, Yukino cast her face to the side and snorted.

Natsu bitterly laughed with the other, after made up with Yukino, Lisanna stood up from the living and went to the kitchen, prepared to cook.

Lisanna Strauss worked as a hostess in a night club, she worked from evening till dawn, because of Mirajane and Freed mostly wasn't around in the day, the job to take care Yukino fell into Lisanna, it had been like that since Yukino was in her elementary grade.

Therefore, in term of closeness, Yukino was much more intimate to Lisanna than her own parents, but it didn't mean Yukino had an ill relationship with them, she was very sensible about it, understood her parents' hard work, perhaps Lisanna herself told her that, a proof she had been taking care her niece quite well.

The study continued, Natsu was able to comprehend many difficult subjects, thanks to Laki patiently guided him, although he was still nervous whether he could enter the top 30 ranks, it was certainly impossible for him to do it alone.

The day was getting late, they studied for about 2 hours before stopped, people said that 2 hours was the limit for someone to keep a focus on studying, afterward, their mind would just be getting bored and started to create a distraction.

Natsu, Laki, and Kinana bid goodbye with Yukino, Kinana was taking a taxi, leaving Natsu and Laki to walk the street together, before riding off, Kinana winked at Laki while Natsu wasn't watching.

It was a rare occasion for the two of them to be alone like this, Natsu didn't know what he should say to her.

"Em... Natsu?"

After quite a moment of silence, Laki who had been staring at her own feet finally perked her face, looking at the boy who was much taller than her.

"Yeah?" Natsu turned his face toward her and smiled.

"Mm... are you... are you busy?" Laki quickly cast aside her eyes, her heartbeat thumped quite strongly, she was somewhat unable to bear to stare at his smile, it was such bright and soothing visual appearance.

"No, not really, why?" Natsu wrinkled his eyebrows.

"You see, I uh... want to buy a book, do you mind... accompanying me?" her voice was getting lower and lower, it's like it approached the voice of mosquito's buzz.

"Right now?" Natsu thought for a while, he looked toward the sky that was getting darker, it was indeed not good for a girl to walk alone at this hour, then he nodded to her, said, "ok."

"Ah?" Laki's face brightened up, then she said with an excited voice, "thank you, I thought you're going to reject."

"No, of course not, we are friends after all, how can I?" Natsu grinned, but unknown to him, the grin and his words actually dimmed if not extinguished the purple-haired girl's spirit, quick her expression froze and her steps lagged a bit.

"A friend?" Laki mumbled, her eyes couldn't help but weakened in bitterness.

"Huh, is there something wrong?" Natsu naturally heard her, he didn't know why she suddenly became dispirited, did he say something bad?

"Oh, no, no, hehe, I am happy that we become a friend, I don't have many friends," Laki faced him while raising the corner of her lips, said with small laughter.

"I see... eh..." Natsu rubbed the back of his head, honestly, he also didn't have many friends, otherwise, he wouldn't hang out with Gray all the time.

Afterward, both of them continued walking the street, Laki uttered a low sigh, but she patted her cheek and looked at Natsu's back with strong resolution.

Next month, the result of the mock exam came out, Natsu couldn't believe his eyes when he received the result, 28... he actually managed to enter the top 30th rank of Fairy Tail's academy score, his torture of study was finally paying off, as long as he could keep this rank stable, he believed that he was 100% would be able to advance into the senior highschool's department, he didn't have to rely on his mother's help to enter the school through the back door.

Cana looked at Natsu who grasped the paper in his hand with absentminded eyes, she smiled gently, said, "Congratulation, student Fernandez, you sure work quite hard."

The teacher also didn't expect Natsu to be able to score this high; if this was the era of Jose, she would have suspected him of cheating but considering Erza's tight system, he was unlikely dared, let alone his mother was the principal herself, perhaps he would have afraid to create embarrassment for her.

On the day of his grades came out, Natsu deliberately left school without going to his mother 's office, straight going home. He wanted to make her think that he didn't succeed, therefore did not have the guts to see her.

Erza, as the school principal, was not in charge of the mock exam, after the score had come out, it was systematically ranked by the grade director, and it was uploaded to the school computer at the end. As long as Erza did not check it personally, she would hardly know the result, it was just as a mock exam, after all, rarely handled by the principal unless there were any accidents.

Sure enough, back at home, Erza asked Jellal where Natsu, he told her that Natsu was in his room and might have failed the mock exam because when he came back, his face was depressed.

"Ok," Erza said and took off to her son's room after taking off her shoes.

She opened the door and saw Natsu sat on the bed with sadness in his eyes, she sighed and came over to sit next to him, said, "Is the result bad?"

"It's okay, it's just a mock exam, doesn't mean much, what important is your effort, Mom knows how much you have studied."

Natsu shook his head, then looked at Erza with an unspeakable gaze, said, "The result isn't bad, but..."

Erza quietly smiled, said, "Ah, do you still care about what Mom said last time? Mom admits that it is too much for you to break through the 30th rank, Mom said that just to motivate you."

"But Mom is satisfied with your behavior, Mom know you don't waste time to play around, Yukino's mother is after all Mom's friend, and she told Mom these friends of yours that helped you study, Mom believe you have worked very hard, and the fact that is you are feeling sad because of the unsatisfactory academic performance, Mom is happy, know that you have changed and care about this."

Erza touched his forehead and her breasts came close to his face, said, "it's okay now... Mom will not ask anything again, if... if you want to touch... Mom's breast, then..."

At this moment, Natsu took out his transcript, although it was rare that his mother would come to comfort him, this time he really did not expect that his mother would disregard their deal, Erza had always been the type that break promises, this was her principle. But she was willing to do so in order to comfort Natsu, simply because he did not pass the mock test, Natsu couldn't help but feel touched.

"Mom, the result is not bad, but extremely good..." Natsu grinned.

Erza looked shocked after receiving his transcript. She didn't expect that he would actually meet her requirements. When she was talking about it, she was just trying to make things difficult for him.

"As long as it is for you, I will work hard to achieve."

"Really?" Erza recovered from the shock and showed a happy smile, "then how about reaching the top 10 next month?"

"Mom, please kill me?"

"Eh? but you can achieve this great, why stop at 30th?"

"Oh, forget it, I won't touch Mom again, it's not like your breast is going anywhere."

Suddenly, Erza pummeled his head, said with a snort, "See how unpleasant it is being deceived? Didn't you just do that to Mom a few moments ago? Feeling good to bully Mom?"

"I just want to surprise my mother. Mom, you promised it. If I have passed the 30th rank..."

"You child, how come this is the only thing inside your brain, you don't have anything to worry about it..." Erza poked his forehead.

"Then Mom does this mean..." Natsu said ecstatically.

Erza gave a charming glare and didn't speak. Two blushes appeared on her face.

Natsu couldn't help but hugged his mother, and then quickly climbed up to grasp the pair of standing tall Madonna, rubbed it frantically through the clothes.

Erza was caught off guard, and immediately broke free, calling out in horror, "Are you crazy? Your father is outside, do you want your mother to die?"

"Oh, haha, sorry, Mom, I forget," Natsu stopped and rubbed the back of his head while spitting his tongue.

Erza sorted out her clothes that were a bit messy and rolled her eyes at him, she felt like since she fell in love with this little devil, she rolled her eyes more than she had experienced in decades before.

"Forget it, I'm too lazy to talk with you," Erza sighed, she didn't know what she should do to scold her son, as a mother? or a lover?

Then she got up and left his room.

The hard work was eventually be rewarded, after getting his mother's permission, Natsu could finally climb again the dream he had always wanted. The breast he had long coveted it, even after becoming a couple with her, he was unable to feel them wantonly, but now there was no barrier for him other than his father.

Thankfully, his father was not a person who could stay at home. He was often going to the Mahjong Hall and came back late, this gave Natsu a chance to intimate with his mother. However, Erza was not an easy-going person. No matter what happens at school, she refused to let him touch her. Even at home, if she was working or doing things, she didn't allow him to do it. But when she was finally done, Jellal came home. There were several times he was waiting for Erza to be done with her work, finally, when she was walking out of the study, his father came back from the outside, making Natsu's waiting became fruitless.

Was there any more pitiful situation than this? It's like waiting for someone's fruit to fall from the tree but the owner came right at the ripe time and chased him away.

However, there were still opportunities, for example, if his father came back really late, Natsu could taste the fragrance of his mother's rich breast.

Erza's breasts were really the best, although some European and American actresses did have bigger breasts, it somehow couldn't hold comparison to hers.

The tender buds, the flamboyant love, the plump and big breasts, and her slender figure were completely unequal, Natsu wondered how his mother supported such a huge meatball. They were also full of the fragrance of milk, which a girl's breasts would never have. The breast milk that Natsu grew up with was full of soft and maternal glory, never made him felt tired or bored.

Sadly, that Natsu mostly could touch them through her clothes, whenever he wanted to pull his mother's clothes, she would hold his hand to stop me from continuing.

Natsu couldn't help but yearn that one day, she would allow him to taste them directly.
