Diane(Seven Deadly Sins)

The war has finally ended, and The Seven Deadly Sins were currently on vacation, peacefully spending their days together. At this point in time, Meliodas and Elizabeth had begun dating, King and Diane had also became official. Each couple would agree that they're definitely happy with their respective relationships. Meliodas continued to grope Elizabeth, while Diane and King were more of the romantic type. 

During their vacation, the entire group of the Seven Deadly Sins took a trip to the beach, where all of the girls wore their swimsuits. (Search NNS OVA 3 if you want to see what they look like). While Diane typically wears revealing clothing, seeing a giantess in a swimsuit was a first for everybody. Even though all of the men in the group had their respective girlfriends, they all had to admit that Diane was unbelievably sexy. 

When she was in her human form, she still had a voluptuous body, with large bodacious hips and a rack comparable or even bigger to Elizabeths. When she was in her regular form, however, her breasts were literally ginormous and her ass was incredibly plump too. Obviously, Meliodas was aware of these things before the beach trip. But, seeing her wearing a swimsuit was weirdly erotic. 

During their beach trip, Elizabeth actually caught Meliodas sporting an erection, thinking it was her swimsuit that caused it. While she definitely looked attractive, Meliodas didn't have the heart to tell her the reason why he was so horny was because he'd been staring at the busty giantess the entire time. Man, for once in his life, Meliodas was kind of feeling jealous of King. He knew that they hadn't done anything sexual yet, like him and Elizabeth did, but he fantasized about having sex with a giantess and it was nothing short of erotic. 

Later that evening, Diane and Elizabeth went to wash off in the hot springs. (See OVA 2) They were both completely nude, and Meliodas knowing this, casually snuck up on them from the bushes of the forests and casually hopped into the hot spring naked as well. "Captain! You perv." teased Diane as she laughed when she saw Meliodas swimming naked with the two. 'S-Sir Meliodas!" squealed Elizabeth in surprise. He swam over to Elizabeth and put her in an embrace where he jokingly lightly groped her. 

He tried to sneak glances at Diane's naked form and he begun to be incredibly aroused. Her soft skin was glistening because of the water, and he caught a glimpse of her ginormous ass when he swam in the hot springs. It was breathtaking. Not to mention how fucking large her breasts were, her nipples were practically the size of his face. Most girls would have kicked out Meliodas already, Elizabeth was shy, but they had been dating already and she's comfortable being around him like this. On the other hand, Diane didn't mind too much either as she finds Meliodas attractive, evident with the crush she had on him before she remembered her feelings for King. 

*Later that Night* 

Everyone began to sleep outside, everyone using a sleeping bag as they camped the night out. It was nearly 2 in the morning, and Meliodas couldn't seem to sleep as his mind was preoccupied with the Giantess on the squad. He tried his best to shake away his diry thoughts, and tried to remind himself he had the love of his life Elizabeth with him. But, he couldn't shake the feeling of his sexual curiosity for the attractive giant girl on the team. Would he even be able to pleasure her with his cock? Her vagina was clearly significantly larger then his penis, and she could probably barely feel it if they did have sex. 

Meliodas was definitely hoping he could run into one of those mushrooms against that shrunk people. Gasping at his dirty mind wandering around, he snapped himself back to reality by slapping his own face and shaking his head. "Must not think impure thoughts, must not think impure thoughts." He looked over across the field, and saw that everyone was sleeping. Taking a deep breath, and making extra sure nobody else was awake, Meliodas stepped out of his sleeping back and slowly walked over to Diane. 

Diane was still wearing her swimsuit, as the weather was incredibly hot and they were going to go swimming in the morning again. Meliodas began to breathe heavily as he slowly approached her crawled, sleeping form. Her ass was literally bigger than him, it was that enormous. Taking another quick peek around, he softly placed his palm on her massive buttcheek and began to squeeze. "Woah, it's really soft." he thought to himself. He was incredibly nervous as he began to slowly take his penis out of his boxers. "Forgive me, Elizabeth. Just once is all I need. You're still my favorite." he thought to himself trying to make up an excuse to trick himself into thinking this is okay. 

He slowly inserted his penis under the fabric of Diane's bikini, and rubbed his erection along the very large flesh of her buttcheek. He had to close his eyes because of how soft it felt, and continued to rub against her ass just for a few minutes. He extracted his penis from her bikini as he tried to continue his exploration of her body. 

Little did Meliodas know, but Diane was having trouble sleeping herself too. The entire time she was supposedly sleeping, she was actually awake. She thought that it was King that was touching her at night, surprised since he hadn't done that to her yet, she wanted to give him a surprise when he walked in front of her. 

When Meliodas walked around her and ended up in front of her, Diane was shocked to see it wasn't King who was touching her. "Captain?! What is he doing here? I thought he had Elizabeth.." she thought to herself. Meliodas could hardly contain himself as he stared at her large breasts. He was breathing so heavily that Diane almost laughed when she peeked at his facial expression. She hated to admit it, but a part of her still held that little crush on Meliodas. So, instead of stomping him into the ground for essentially molesting her, she let him continue for now, as this was also the first time someone had touched her like this. 

"Holy shit." he thought to himself as he slid his hand underneath her bikini top. He could see the areola of her nipple and it was gigantic. He walked up to the large flesh on her chest, and practically hugged it as he started to hump into the flesh. It was kind of hard to give himself a boobjob given the angle he was provided, since she was sleeping on her side. He didn't care either way as he begun to feel intense pleasure from her large breasts.

He noticed that Diane began to start breathing heavily, since she was so big he could practically feel a gust of air everytime she breathed on him. Having enough of pretend to be asleep, Diane slowly whispered "C-captain." Meliodas shuddered in fear as he feared that he was going to be smashed into the floor. Closing his eyes and bracing himself for dear life, he slowly opened his eyes after nothing happened the next five seconds.

"Captain. It's okay. You can keep going." she whispered. "W-what? Really?" questioned Meliodas, genuinely shocked. "Just keep it a secret, okay?" said Diane. "O-of course! I wouldn't want Elizabeth to find out either." he confessed. "Haha, Captain. You're such a naughty perv!" she teased. "That I am." he said as he rubbed his cheek. His erection was still out as Diane began to stare at it. Compared to her body, it obviously looked quite small to her. "I-is that, what a p-penis looks like, Captain?" she innocently asked. 

"Yare, Yare. Did King never show you before?" Meliodas teased. "O-of course not! He's not a perv like you, captain." she replied, defending her boyfriend. The entire time she was talking, he could feel her breath blowing against his entire body. Of course, his dick was out in the open, so her breath was sending shivers down his spine as it felt good against his penis. "Do you want to get a better look, Diane?" asked Meliodas. "Mhm!" mumbled Diane as she innocently nodded her head. 

Meliodas walked really close to her face, and was standing really close to her lips with his erection out of his pants. "It's kind of small, huh Captain?" she asked. "W-WHAT? I'll have you know, for human's this is quite larger than the average size! I'm sorry i'm not some type of giant that could satsify you!" he outbursts in a comical rant. "I'm sorry! I didn't mean that!" she tried to apologize. "C-captain. Why are you doing this to me anyways? Didn't you pick Elizabeth." she asked with a pout.

He had a slight blush on his face as he looked away when he answered. "I-its cause I thought you were really beautiful, Diane." he half-lied. She was definitely pretty, but he was touching her because of how turned on he was from her giantess body. He wanted to keep the conversation going as his penis was tingling every time she breathed on him. Knowing she was an innocent virgin, a lightbulb popped up above Meliodas's head as he got a bright idea.

Diane, in response to Meliodas's compliment, let out a little gasp as she blushed. "R-really, Captain? You really think that?" she asked. Meliodas nodded his head rapidly, "Of course, of course! Everyone thinks you're very attractive, Diane" he assured her. "Awww! Captain!" she said with excitement as she closed her eyes and stuck her lips out for an innocent kiss. 

She's given King's kisses before, but they were always of the pecking type rather than anything sexual. She understood the meaning of it, but to her, the Captain was also someone that she cherished a lot, comparable to King or maybe even more. Meliodas was surprised to see her stick out her lips like that, and had a pervy grin on his face as he leaned in to kiss her back. Her lips when gathered together like that was almost the size of his face, as the got pretty much everywhere on his face but his eyes kissed as well. 

Diane was confused when Meliodas held the kiss for longer than usual, and kind of sat there awkwardly as she waited for him to pull away. The next thing she knew, she felt a weird hard object pressing against her bottom lip. With a quite audible kissing noise being made, since her lips were so big, she pulled her head back a bit and looked curiously at Meliodas. 

"U-um, Diane. Did you know that a man's p-penis tastes really good?" he asked her. "H-huh? Isn't that what the men use to pee? T-theres no way something like that could" she stammered. "Trust me, Diane! Have I ever lied to you?" he asked with a valiant grin on his face, trying to convince Diane he was the most trustworthy person ever. When in reality, he just wanted to see what a giantess sucking on his dick would feel like.

"You-you can't tell King about this though." Meliodas whispered to her. "I-I knew it! It's obviously something perverted! It's always perverted with you" she shouted as she scolded him. "Keep it down Diane! Just trust me. If you do it for a while it'll start to taste good." said Meliodas, visibly panting from his anticipation. 

He stuck out his lips in a kissing face trying to give Diane a hint. She blushed and said "F-fine! I'll try it. If it tastes bad, I'm going to hit you ya know?!" as she formed her lips in a kissing face. He leaned towards her as he kissed her lip again. It felt weird because her lips were practically covering his face. He opened his mouth as he begun to lick her lips, Diane, getting the cue opened her mouth and slipped her tongue out to lick back at Meliodas.

Meliodas almost laughed as her warm tongue was pretty much licking the entire bottom mouth of his face. But, he stuck his tongue out and did his best to kiss her back with his tongue. As they continued to try to make out, Meliodas had to stop and pull his face away as there was just too much of her saliva on his face and he could hardly breathe. "Okay, so making out with a giantess is definitely a no-go" he thought to himself as he panted from the kiss. 

"W-was it bad, Captain? Am I a bad kisser? She frowned. She definitely tried her best in that kiss, but maybe it was a bit too passionate and lasted a little too long, as his face was drenched in saliva. "No, no! It felt really good, I just didn't want to force you to kiss any longer!" he lied. "I-im okay with it." she said as she brought out her tongue again to kiss.him. He reluctantly opened his mouth as she licked his face and tongue at the same time, before he stopped her lips with his hands and then slowly inserted his erection onto her tongue.

Diane stared at him with open eyes as he arched his back as pleasure began to flow over him. Her mouth was just the perfect size to give him one of the most unique blowjob experiences in the world. "HOLY SHIT." he thought to himself as her mouth was the most warm, wet thing you could insert your penis in on the entire planet. He started to throw his head back in pleasure, closed his eyes and slowly thrust against her tongue. 

Diane just sat there with her mouth opened, and was trying to taste his dick. It didn't taste particularly good or strong, but Meliodas did promise her it would taste better the longer she did it, so she stuck in there and started to lick at his erection. "C-close your lips around it, Diane". Asked Meliodas. Nodding and following his instructions, Diane brought her huge full lips down and closed it over his penis. "OH, my GOD! Unggg" he moaned. His entire penis, ballsack, was being engulfed inside her plus sized mouth.

She began to blush as it was apparent that Meliodas was feeling really good from just her mouth. "D-diane. Could you suck it please? And uh, start using your tongue on it" he awkwardly instructed her on how to suck a cock. She opened her mouth to speak with his cock still in her mouth as she mumbled "o-okay." Erotic wet noises was starting to be made as Diane started to close her massive lips around his entire dick as she started to move her tongue against him. 

It was the best feeling he's ever felt, her tongue was able to lick the entirety of his dick as his entire lower half was practically submerged into her warm, wet cavern. Her body temperature felt much hotter than a regular human, and this blowjob was worlds better than what Elizabeth gave to him. He completely forgot everyone was sleeping, and he just noticed how loud her lips were smacking when she was sucking him off. As unfortunate as it was, he had to end this quickly. 

Diane brought her hand to his back and started to push him towards her a bit, as she kept opening and closing her massive lips against his penis. Meliodas held onto her cheek as he started to speed his thrusts up against her tongue. "C-can you hum for me, Diane? Requested Meliodas. Diane slowly began to hum, and it caused a vibration in her mouth that intensified the pleasure he was feeling from her mouth. 

"Unnggg" Meliodas began to moan as his shaft started to pump semen onto her large tongue. "D-diane, suck my penis." he told her. Diane nodded and started to suck on his cock, tasting his semen as she started to drink her little treat. "C-clean it with your tongue." he instructe her as she opened her mouth to lick all around his dick, which ended up licking all around his thighs as well. Finally, as his eruption was dying down, she closed her lips onto him one more time trying to make sure he finishes.

"D-diane?" King questioned as he wiped his eyes, tired from randomly waking up. As soon as King woke up, all he could hear was wet, almost slurping noises coming from Diane's reaction. Panicking, Meliodas urged Diane to open her mouth. Shocked, Diane opened her mouth as fast as she could before Meliodas hopped into her crevice. "Y-yes king?" she said, voice sounding muffled as Meliodas was holding onto her tongue. "What was that noise?" questioned King, who was yawning. "N-nothing." she avoided speaking too much as Meliodas was holding onto her tongue for dear life. It was a weird experience being inside someone's mouth, not to mention that his dick was pressing against her wet tongue. Meliodas cursed himself as he found himself getting hard again, and continued to hug her long, wet tongue as she started to rub his cock against her tongue. 

At this point, Diane was communicating with King with subtle nods and shaking her head, as she was unable to talk as currently the Captain was holding onto her tongue and thrusting his dick on it. Luckily for both of them, King started to drift back to sleep. Diane opened her mouth to let Meliodas know that it was safe to exit, but he stayed back there a bit on continued to hump her tongue. He groaned as he let out another spurt of semen that sprayed on her tongue. He crawled out of her mouth and was covered in her slimy saliva. 

"C-captain. It doesn't taste that good." she glared at him. He rubbed the back of his head and apologized to her bowing down. "To make it up to you, Diane. I'll find you one of those shrinking mushrooms!" he promised her. "Why would I need that, Captain?" she asked innocently. "That way, you could feel it when we have sex!" he exclaimed with a grin. She gasped and said "C-Captain! We can't do that!" stammered Diane. "It'll be our secret, okay?" he panted.
