It’s said that if you want to know how a girlfriend will turn out, you have to look at their mother. Futsuo had been friends with Nikuko in middle school. She had been trying a different diet after being pudgy in elementary school, but her mother’s genes were still strongly showing. Despite her, at the time, slender frame, she still had some of the biggest breasts in class. That was what would draw anyone’s attention. For Futsuo, it was something different.When Nikuko was stretching during PE, he caught a glimpse of her navel. School swimsuits covered up the midriff, and even the summer uniform still left a lot unseen. Catching a glimpse of a girls’ stomach was a gateway to imagining the rest of her. What her breasts or her loins might look like, each only a short distance away from the navel that opened his eyes to Nikuko’s sweaty body. He talked to her during PE, and she was surprisingly personable.When he talked about geology, she was interested in what he had to say. He helped her with science lessons, and she helped him cover for his weaknesses as well. It wasn’t long before he was invited to her house to meet her little sister and her mom, a Russian expat with a well-proportioned body. Her mother was very generous to him, and welcomed him into their house.By the time they reached high school, Nikuko took up futsal. Her metabolism had also changed. She found that sticking to her diet wasn’t making her all that satisfied with her school life. She wanted to eat what she liked, since she exercised plenty, and would be doing even more since she joined the futsal team. As she did, she began to regain her old weight, with her belly filling out over the summer to hang off her body. That’s how she picked up the nickname of “Nikuko.” Though it was a bit of a fat joke, she was surprisingly okay with it.When Futuso asked, she would say. “Well, yeah, I’m fat. So’s my mom and my little sister. We’re just naturally chunky. But that’s nothing I should feel bad about. I like my body, I like playing futsal, and I like you. You don’t have to worry about it on my behalf.”He was still paying attention to her during PE. Once again, her shirt, which was just barely big enough for her, was pulled away from her body, exposing the folds of her round, pudgy belly to the cool breeze outside the school. Futsuo’s first exposure to that side of her had been when he met her mother. Maybe it was because she was Russian. Maybe it was because Nikuko and her mother carried herself with the same confidence. But there was a feeling in himself he couldn’t shake.Ever since Nikuko had rebounded and gained weight, she’d become even sexier. Her stocky arms and legs were just as toned with muscle as they were shielded by fat when he walked arm in arm with her, and her belly didn’t seem to be a detriment at all. She kept her breasts in place with a sports bra when she was running, but her belly bounced freely. She didn’t even seem to notice. The only time it had come up was on a trip to the art museum.The class was looking at older artworks by the likes of Rubens and similar. It was explained that back in those days, chubbier women were seen as sexier. Nikuko saw herself in those artworks, and gained even more confidence, as well as an awareness of her sexuality. Now she knew that not only could her body be normal, it could even be sexually attractive. At the restaurant the class stopped by afterward, she wanted to eat more to make her belly even bigger and sexier.Futuso had been sitting a few tables away from her after she finished that meal. She could always eat really big portions, and her already large stomach was taut with food from her splurge. The only people who had really seen Nikuko’s belly before were the girls when they were changing for PE or swim class, and none of them had ever really commented on it. That Nikuko was lifting up her shirt and showing her food-bloated belly to Futsuo, and asking him to rub it, was a sign of trust that he wasn’t completely ready for.“You’re not self-conscious about it?” he asked. “It’s okay? I can touch it?”“It’s just a belly. You don’t have to be nervous,” said Nikuko.“But it’s so big. Isn’t it like a boo... a breast?” asked Futsuo.Nikuko laughed. “I never thought of it that way before. It’s soft, but it’s not exactly like those places.” She looked down at Futsuo. She noticed a part of his pants was sticking up. “I really must’ve gotten sexier. I can see your boner.”“Should I hide it?” he asked. “I’m sorry.”“What’s there to be sorry about?” said Nikuko. “Futsuo? Do you like fat girls?”He thought back to what Galko had told him. “It’s normal for people to be weird!” He thought that only applied to his love of geology, but it could just as easily apply to this situation, too. Nikuko clearly wasn’t hesitating. He had to work up the courage and answer honestly.Futuso hesitated for a moment, and then answered. “Ye-yes! Your soft, squishy body looks really sexy! I didn’t know if my crush on you would go away in high school, but it’s only gotten stronger. I love you, Nikuko!”Nikuko laughed. “I’m not squishy all over. It’s mostly around the torso. But those are your favorite parts, right?”Futsuo nodded.“That’s awesome,” said Nikuko. “My mom had a ton of admirers from her wrestling days, so I see I’ve gotten it from her. You’re in a trance rubbing my belly, but I bet you want to see my booty and boobs too. How’d you like to see all of me? I’ll show you how sexy I’ve gotten over the summer,” said Nikuko.The rest of the time was spent with Futsuo rubbing Nikuko’s belly. His hands seemed to sink into her stomach. He could hear and feel the food rumbling in her gut behind his palm. The way Nikuko’s soft, sticky flesh moved in relation to his hands kept him hard. The thought of her belly warmth on his hand kept him excited for the rest of the day. When he got home, he wanted to masturbate immediately.Nikuko worked extra hard for the futsal team the next day. Her uniform was sticky with sweat. Her overly large breasts, trapped in her sports bra, were still marinating in sweat. She wanted to get her body sweaty so that Futuso could get hard immediately when they later met in the classroom. Her sweat was not only getting trapped in her armpits, but also in her stomach rolls and the cleavage of her ass. Her sweat had a distinct odor that all the boys found kind of sexy, but Futsuo most of all.Once practice was over, Nikuko skipped taking a shower and went immediately to an empty classroom that was frequently used for sex. Galko’s sister had made it an unofficial “Virgin Breaking Club” back in her days. She didn’t get caught, but the thrill of doing so only made her cum harder when she was using it. The room had gained a reputation for raising one’s libido because, no matter how many times it was cleaned, the smell of sex lingered. That was why Nikuko chose it for her first time.Still sweaty, she was waiting in the classroom. Futsuo arrived, and locked the door behind them. Club activities were still going, so the teachers wouldn’t be coming by at this time. Nikuko lifted her uniform above her head, revealing her sweaty belly and sports bra. Even though it was a high end one, it could barely contain her massive breasts, the tips of her npples visible beneath the fabric.Nikuko reached for her belly and began squeezing it in her fingers. Drops of sweat fell form her navel and the muffin top around her shorts, staining the classroom floor with a thick smelling sweat. Nikuko lifted her stomach up and let it flop back down, the fleshy slapping around causing Futsuo to instantly become hard inside his pants. Nikuko was seducing him in exactly the way he had hoped for.“Look at you, you’re so hard,” she said. “I had no idea my belly was so seductive.”“It’s glazed with sweat. I want to lick it and touch it,” said Futsuo. “Your belly button looks delicious.”“Let me do one thing first,” said Nikuko. She removed her sports bra, letting her breasts fall onto her chest. Her nipples were wide, with bright red tips that looked gorgeous against the afternoon sunlight. “Don’t stop your licking at my belly. My nipples are all stuffy and hard, too.”Futsuo ran over and embraced Nikuko, getting on his knees. He planted a kiss on her belly button, the salty taste and scent of her sweat meeting his lips. His face was surrounded by her stomach folds, her soft, squishy girth wrapping around his face. At the same time, his hands made his way back to her butt. They were covered by her underwear and spats, yet he was surprised at just how amazing Nikuko’s butt was to the touch.It was covered in plenty of fat, of course, but the muscles underneath were strong. Her butt was tauter than he expected, and its width gave him plenty to hold onto. Nikuko reached behind and lowered her panties and spats, leaving herself wearing only her skirt. Now with her bare bottom available for his leisure, Futsuo dove in. He continued kissing and sucking on her stomach flesh, his nostrils filled with her sweaty smell.“You’re really getting into it,” she said.“I’ve loved your belly ever since I saw it in middle school,” said Futuso. “Now that it’s so pudgy, I love it even more. Your belly’s amazing!”“Don’t ignore the rest of me,” said Nikuko. “You show me yours, too.”Futsuo unbuttoned his pants and pulled down his boxers. Like the rest of him, his dick was average. Yet right now, it was erect, and larger than Nikuko had been expecting. His sweaty balls, stuffed inside his pants all day, were dripping with sweat and tight with lust. Nikuko reached her palm down and began massaging his balls, getting a feel for them between her fingers, taking in every wrinkle of his sack.“You’ve got a real springy pair,” she said. “I can’t wait to taste what’s inside.”Nikuko licked along his balls, letting her tongue make its way to the underside of his shaft. She bounced the head around on her tongue, savoring the unique flavor of the drops of precum spilling out of the tip. The flavor kinda reminded her of the protein bars she liked to eat before a futsal match. Without hesitation, Nikuko sucked the tip inside her mouth, rolling it around.“This can’t be real. The girl I’ve had a crush on for years is blowing me,” thought Futsuo. “I can see every part of her chubby body swaying as her mouth is on my dick. How did I get this lucky?”Nikuko let his dick go from her mouth. It bounced back and forth for a moment, drops of her saliva falling from the tip. Nikuko picked up her hefty breasts and wrapped them around his dick, the average stiffy vanishing into the meaty expanse of her chest. Only the head poked up as Nikuko pushed it out of her breasts, licking the tip while her sweaty chest covered the rest of him.It felt warm and squishy inside her breasts. Those breasts, normally kept inside a sports bra all day, were dangling free and being used for him. Futsuo reached down and pinched Nikuko’s nipples. Her tips were much harder than he expected. She was into this, and feeling incredibly horny. Nikuko moaned a little from the stimulation, her tongue changing its motion on top of his dick.“I thought back at the restaurant was the first time you saw my belly,” said Nikuko.“Otao accidentally caught a glimpse of the girls changing after swimming,” said Futsuo. “I think he was more focused on Galko, but he said he saw your round belly sticking out. I knew it was you. Please don’t lose any weight!”Nikuko laughed. “It’s my family. You’ve seen mom in her swimsuit when you came to visit. She’s even bigger than I am. Would you be okay if I looked like her in a couple of years?”“I’d love it!” said Futsuo.“Then let’s become lovers. Give me your cum, Futsuo,” she said. “I’ve been hungry for it all day.”Nikuko pressed her breasts in against the sides of his cock. The overwhelming pressure from her strength was too much. Futsuo sprayed a shot of cum from his glans. It landed on Nikuko’s glasses, dripping down across her nose and lips. Nikuko reached upwards and scooped it off, letting the cum that had landed on her chest remain. With her finger covered in the salty icing, she swallowed it like it was a free sample at a bakery.“Delicious,” she said. “It’s even better than I thought. Tasting your cum got me really wet. If you’re still hard... do you want fuck a fat classmate?”Upon hearing those words, Futuso’s dick became hard once again. Nikuko bent over on one of the desks. Her belly pressed into the table, squishing out and spreading outward like a stress ball. She grabbed her butt cheeks and spread them apart, revealing her pussy. She had much less hair than Futsuo was expecting. It was expected from an athlete. Only a few stray black hairs remained around her pussy, but it was enough to keep Futsuo hard. He was more entranced by her puffy lips, dripping with the nectar of arousal.“Galko’s got way more body hair than I do,” said Nikuko. “But I can let a little bit grow in if you want. It won’t affect my performance that much.”“This is fine!” said Futsuo, staring at her twitching butthole. “I-I’m going in!”“Today’s a safe day, so give me all that your dick can handle!” said Nikuko.Nikuko’s wet pussy swallowed up his cock with little hesitation. She had broken her hymen from playing futsal and masturbating, so there was little resistance to welcoming his cock. When her plump lips closed around his dick, he could feel the warmth of her folds enveloping him. With Nikuko’s plump size, her body was warmer than most girls’. He gently rocked back and forth inside her pussy, getting accustomed to her tightness. He could stay in, but she wasn’t going to let him leave.“You’re not bad,” said Nikuko. “If this is an average sized dick, I’ll be a happy girl. Come on, start pounding me!”Nikuko grabbed onto the edge of the desk as Futsuo wrapped his hands in her butt cheeks once again. As his hands sunk into her sweaty ass, his dick sunk further into her sweaty pussy. The smell coming from where his dick met her vulva, stinking of body odor and secretions, began to fill the room. The windows weren’t open, trapping the scent in the classroom. It was potent and powerful, smelling like young love.Holding onto her ass, Futsuo began to get his rocks off. His balls slapped against Nikuko’s pudgy ass, every meeting with her tush vibrating to his dick inside her. Nikuko moaned, sounding a lot like the grunting noises she made when kicking around the ball. All the fat on her body, including her breasts, her thighs and especially her belly, jiggled with every thrust of Futsuo’s cock. It was like a ripple on the surface of the water, spreading across her flesh.“I love sex!” said Nikuko. “I’m glad my first time was with you, Futsuo. If you ever want to fuck, you can come over to my house anytime.”“What about your mom or your sister?” asked Futsuo.“My sister is friends with Kibami. She said Kibami’s brothers love boobs, and I have something to do with it. She’s fine knowing about this stuff. And mom’s always been open about sex,” said Nikuko. “As long as we lock the door, they’ll let us do our thing.”“I want to rub your belly so badly!” said Futsuo, reaching his hands around and grabbing onto Nikuko’s love handles. She was surprised to feel his palms, still warm from the heat of her ass, dig into her belly, but it felt much better. Her pussy tightened up as he began to massage her belly, her breasts swaying back and forth as he pumped inside her. “It’s so good!”“You really like my love handles,” said Nikuko.“Your pussy got so much wetter when I touched them,” said Futsuo. “I love this!”Nikuko, keeping Futsuo inside her as she changed positions on the desk, moved around to start kissing him. She felt like her glasses were going to fog up from the intense heat and sweat being generated by their fucking. Futsuo’s body pressed against her squishy skin, squeezing her breasts and belly in reaction to his touch. As the two of them were getting into it, over the sounds of Nikuko’s moans, they didn’t notice the door unlocking.“Abesen said he left something in here. Is anyone...” said a voice.It was Galko. She heard heard that the classroom was sort of an extra storage room, and had been asked to fetch something for her teacher. When she walked in, she was greeted with the sight of Nikuko, nearly naked, and Futsuo, his pants around his ankles, engaged in coitus.“There’s a folder... don’t mind me! I didn’t see anything!” said Galko, hastily shutting the door.“Aw, Galko,” said Nikuko. “We’re almost done.”“This is going to get around,” said Futsuo.“Galko’s a nice kid. She won’t tell on us,” said Nikuko. “Now hurry up and cum inside me, loverboy!”As he continued massaging her belly and breasts, Futsuo’s hard cock began to throb. Being seen had made him even harder, the thrill of being watched making his balls start to tense up in excitement. It wasn’t long before he reached his climax, grunting and spurting out a hot, sticky load of cum inside Nikuko’s plump pussy. He stayed inside her for as long as he could, only pulling out when it was soft.Nikuko licked his soft cock, cleaning up the last few drops of cum. She wanted to taste more of it, and she knew she’d be getting the chance. As their bodies began to calm down in the afterglow of their sex, Futsuo made good on his promise and licked and sucked Nikuko’s nipples. Hers were puffy, with fairly big areolae that were noticeable even from a distance on her oversized breasts.“I’m really glad to have you as my boyfriend,” said Nikuko. “Where do you want to do it next? The pool? The locker room?”“Your bedroom is fine,” said Futsuo. “I barely felt like I could keep up with you.”“Then we’ll have to train you,” said Nikuko. “I can’t wait to do more!”While Futsuo’s encounter with Nikuko was kept secret, his love of fat girls wasn’t. In time, the class came to know they were an item. Knowing that someone like him was hanging out with the star of the futsal team only made their attraction to Nikuko grow even more. Now that she was getting it on regularly, her happiness and confidence only increased further.Futsuo met Nikuko at the poolside a few days later. She was wearing a bikini, showing off the curves of her belly. She was going to swim in the Olympic pool, seeing this as much of a game as a date.“Make sure you’re watching me,” said Nikuko, giving him a kiss. “We’re gonna hit the showers after.”As she walked away, her belly jiggled, and Futsuo felt a stirring in his pants.
