This is a little side story about one of my favourite pairings ever, Natsume and Sasayan from Tonari no Kaibutsu-kun by Robico. Based on Chapter 47 of the manga during their 3rd year summer camp, with elements from Chapter 32.
I have left the Japanese honorifics in for this story, as I find it quite difficult to translate to a comparable meaning in English. If you don't know what they mean, definitions are very easy to find on the internet.

"I say, Sasayan-kun"
Sasahara Souhei, more commonly known as Sasayan, had just changed into some comfortable shorts and t-shirt, and zipped himself into his sleeping bag when he heard a faint whisper from outside his tent flap. Thinking he was just hearing things, and as he was very tired, he ignored it and settled down to a more comfortable position in his sleeping bag.
"I say, Sasayan-kun, Sasayan-kun! Open up!"
The whisper came again, slightly louder and more urgent this time. Sasayan unzipped himself from his sleeping bag with a sigh and crawled on his hands and knees in the small tent till he reached the foot of his sleeping bag at the tent entrance. Opening the tent flap revealed a very attractive girl of his age crouching outside his tent, wearing a thin striped jacket, black gym shorts and simple white beach sandals.
"What took you so long Sasayan-kun!" Natsume Asako sulked as she moved towards the tent entrance, "There are lots of bugs out here."
Sasayan moved aside to let the girl in, a look of surprise on his face at this unexpected late night visit. Well it wasn't all that late, but as there was not much to do at this river once the sun went down and as everyone was tired from playing all day, they called the night in early.
"What's up, Natsume-san," Sasayan asked while stifling a yawn, sitting cross-legged near the head of his now open sleeping bag, as he watched Natsume awkwardly take her sandals off before crawling onto the foot of his sleeping bag to take up a sitting position, hugging her arms around her knees to her chest.
"Uhh…Well you see Sasayan-kun…I couldn't show you earlier today…and you seemed like you really wanted to see…but all the Kaimei boys were there and teasing me…so you see I couldn't…but I really wanted to show you…" Natsume rambled on, staring at him uncomfortably as she hugged herself tighter.
"What are you talking about, Natsume-san?" Sasayan yawned while watching her with quite a puzzled look on his face, and wondering if he had to listen to another of Natsume's nonsensical rants before he could go back to sleep. Natsume raised her head to look at Sasayan straight in the face.
"I wanted to show you my bikini, Sasayan-kun." Natsume replied softly, a slight blush appearing on her cheek as she looked down at her feet. With that said, all signs of sleep rapidly left Sasayan as he processed her words. As with most healthy high school boys, the mere mention of 'bikini' is enough to capture their full attention.
"Whatt…what?" was all Sasayan managed to reply in puzzlement, wondering if he had misheard her.
"You were very happy seeing it last time…so I really wanted to show you this time ..and I look really cute in it as well," Natsume continued on, voice gradually becoming smaller and smaller.
"That is true…but here? Now?" Sasayan replied, still a bit anxious.
"Yeh, I wasn't able to take my jacket off in the river today because of all those Kaimei boys, so now's my only chance." Natsume replied, almost matter-of-factly. "Is it…no good?" She asked, a bit apprehensively.
"Na..it's fine," Sasayan replied, still not fully grasping the situation. But as a healthy high school boy going through puberty, he wasn't going to say no to an attractive girl in a bikini, particularly the very girl he likes.
"Ok good," Natsume smiled contently, and began to unzip her jacket. Sasayan's eyes were riveted to her fingers, appreciating her graceful collarbone, and took a sharp intake of breath as the pearly white skin of her cleavage appeared. The tent dimly lit by the moonlight basked her skin in a soft glow as Sasayan watched her cornflower blue bikini top revealing itself, adorned with violet flower patterns on the undersides of the breasts. Sasayan could see her breathing heavily and looked up to see a slightly apprehensive look on Natsume's face. Feeling a bit embarrassed himself now Sasayan averted his gaze.
"You don't have to do this..Natsume-san," Sasayan asked, a bit concerned.
"Na I'm ok, it just suddenly feels so embarrassing with you watching so closely." Natsume replied.
"But I thought you wanted me to see? And plus, you look really good in it." Sasayan replied truthfully. "I can look away then." Sasayan added, hoping to make her feel more at ease.
"No don't look away, I really want to show you." Natsume exclaimed, confidence coming back into her voice. With that she shrugged the jacket off her slender arms and dropped it in a heap on top of Sasayan's bag and day clothes next to his sleeping bag. Next she positioned her hands at her waist band as she began to pull her shorts off. Sasayan, suddenly feeling really self-conscious himself, tried really hard not to avert his gaze as her matching blue bikini bottom with the same violet flower patterns on the sides was revealed, followed by the creamy white skin of her elegant thighs. Sasayan watched awkwardly as she slid her shorts the rest of the way down her slender legs and off her feet till they followed onto the heap of her jacket next to the sleeping bag.
"How is it?" Natsume asked questioningly, with a hint of anxiousness in her voice.
"It looks…very nice," Sasayan replied, feeling a hot flush in the face as he waged an inner battle with himself as to where to look. The very scantily clad Natsume sitting just an arm's length in front of him, or the much less stimulating corner of the small tent.
"Yay, I am very confident in how I look in these," Sasayan heard Natsume reply happily. He had decided to focus on the corner of the tent while periodically darting his eyes back to the eye candy in front of him.
"You're very brave…Natsume-san…or silly..aren't you worried I might push you down or something?" Sasayan replied, not being able to think of anything else to say. "Didn't you say you think all boys are beasts?"
"It's fine if it's you, Sasayan-kun, I trust you" Natsume replied, her voice a bit softer than before. Sasayan was just pondering whether to be happy that she trusts him or disappointed that she doesn't consider him a threat, when he suddenly heard her ask questioningly, "What's that you have there, Sasayan-kun?"
Sasayan looked to where she was pointing to his lap, and saw to his horror; he had developed a very visible tent in his own shorts. Sasayan quickly reached over to his bags to grab his jacket to try hide it, but accidently brushing against Natsume's clothes with her still lingering warmth on them only exacerbated the problem.
"It's a very normal male thing to happen, particularly during puberty, when a very pretty girl is showing a lot of skin right in front of me!" Sasayan exclaimed, covering himself frantically with his jacket. Natsume looked at him bewildered for a while, before her mouth dropped open in comprehension.
"Oh my!" Natsume gasped, her hand moving to cover her open mouth. "Is that your-?"Natsume asked. Sasayan winced, and then nodded. "Did you get a-?" Sasayan nodded gingerly again.
"Yeh.." Sasayan muttered nervously, not knowing where to look or what to do as panic clouded his mind. Was that disgust in her voice? Perhaps she'll hate me forever now, and never speak to me again? Sasayan thought all these to himself, with a dozen other depressing scenarios running through his mind. He dared not look up at Natsume's face and only kept his eyes fixed on the tent corner.
"Can I see it?" Natsume suddenly asked. Out of all the possible scenarios playing through Sasayan's head, this was not one of them.
"What?" Was all he managed to reply.
"Can I see it..? Your..thing!" Natsume replied, looking quite a bit embarrassed. "I spend a lot of time on the internet, and some of the commenters on my blog talk about their boyfriend's…and it made me very curious…"
"What?" Was all he managed to reply again.
"Oh come on, please, Sasayan-kun! I showed you my bikini!" Natsume replied pleadingly.
"But you wanted me to see your bikini! This is different!" Sasayan managed to retort.
"Pleeasee!" Natsume pleaded again.
Sasayan sighed to himself, weighing his options. Compared to his original scenario of Natsume hating forever him playing in his head, this was a much better option. "I suppose.." Sasayan muttered anxiously. With that Sasayan removed his jacket he had covering himself, to again reveal the tent in his shorts. "There! Happy?" Sasayan declared.
"No not that! I want to see it, your pe-…penis." Natsume uttered out those words with great deliberation. Sasayan, caught quite surprised at her use of the word, looked up at her face to see if she was joking, but seeing the great determination in her eyes, he moved his hands to his own waist band.
"Seriously?" He asked, with his hands poised at his waist band. Seeing Natsume's affirmative nod, he inwardly took a deep breath, and began to pull of his shorts along with his boxers.
Natsume's eyes opened wide as she saw his member become revealed. Sasayan, feeling incredibly self-conscious and very exposed, could only sit there with his manhood jutting straight up in front of him as he determinedly look into the tent corner and anywhere else apart from Natsume.
"It looks so swollen.."Natsume commented to no-one in particular. "Does it…hurt?" She asked Sasayan questioningly, as she examined the red mushroom head and the patterns of the veins lining his shaft.
"No" Sasayan replied, still very determinedly looking at the tent corner. "It's just a bit uncomfortable…." Suddenly Sasayan jumped as though sparked by electricity, his eyes darting back to his lap to see Natsume's delicate hand wrapped around him.
Natsume, as though in a trance, had almost subconsciously reached out to touch him, but had quickly let go when Sasayan jumped.
"What are you doing! Natsume-san!" Sasayan gasped, scooting further back away from her.
"I wanted to try touching it," Natsume replied apologetically, "I thought it was how guys made it more comfortable, by touching it…and since I caused it…I wanted to help make it go away….is that wrong?"
Sasayan was quite taken aback for a moment, before lowering his guard a bit. "No…that's how I usually make it go away…I just never had someone else do it before and it really surprised me." Sasayan wondered to himself why he was telling her so much.
"Can I try touching it again then..?" Natsume asked, peering anxiously at Sasayan. Sasayan looked at her apprehensively for a while, before sighing to himself again, then cautiously moving himself forward in front of her in a cross legged position and then leaning back a bit, supporting his weight on his hands. Out of all the weird things that's been happening tonight, he thought to himself 'what the hell, and decided it wasn't a good idea to deny himself his first hand job from a girl.
Natsume reached out with her hand again, before tentatively grabbing his penis. The contact made Sasayan jump again a little bit, despite expecting it, but not enough for her to let go.
"I've done some research online, and it seems like I just stroke it up and down…is that right?" Natsume asked, experimentally stroking her hand with the skin on his penis as she asked.
Sasayan was trying very hard to think of a coherent reply, as every touch of her hands was sending bolts of electricity right to his head. "Yeh…" he managed to murmur out. "I usually do other stuff as well…such as playing around with the balls.." again Sasayan wondered to himself why he was giving her so much details. Experiencing for the first time someone else's hands on his penis was making him lose many of his thought processes. Her hands were much softer and delicate than his, and touched him in an entirely different way to what he was used to doing to himself, and it all felt incredibly good, new and exciting.
"Tell me if I do anything wrong," Natsume said as she gave another few experimental strokes to his shaft, Sasayan could only nod briefly in reply, his eyes riveted to the movement of her hands sliding up and down his shaft. He then saw Natsume using her other hand to cup his balls and give it a firm squeeze. Sasayan winced.
"Oww!" Sasayan exclaimed, pulling back and covering his genitals protectively with his hands.
Natsume panicked and removed both her hands entirely from him. "Sorry! What did I do wrong!?" She asked, very anxious.
"Na it's okay...what you were doing felt really good…it's just that you can be firm with the shaft but have to be very gentle with the balls.." Sasayan replied, getting more and more embarrassed at his own words. Natsume thought for a moment, processing the information, and then gave him a small nod.
"Can I...try again?" Natsume asked, looking at the head poking shyly through the gaps of his fingers, and reached her hands out tentatively. Sasayan hesitantly removed his hands and held himself towards her again. Natsume again wrapped her hands around his shaft gently and began to stroke it. Seeing the pool of liquid appearing at the tip, she used her fingers to rub it around the opening at the head, eliciting a groan out of Sasayan. Natsume, encouraged by this gripped his shaft firmer, and used her other hand to gently cup his balls very gently as though they were cupping bird's eggs and it all felt incredibly good for Sasayan, bringing out another little groan. The tent was suddenly feeling incredibly hot and he was sweating into his shirt as all the sensations of her hands went straight to his head. First she was just stroking his shaft, next she was lightly rubbing the head with her thumb, all the while using her other hand to cup his balls gently. What sort of research has she done online? Sasayan thought to himself.
Natsume continued her administrations for a while, enjoying the different expressions and responses that Sasayan was giving her from the different things she did. After a short amount of time, Natsume saw Sasayan grip the fabric of his sleeping bag really hard with both his hands as he alternatively looked at her hands on his penis and looked at all her exposed skin right in front of him. Pretty soon Sasayan could feel himself nearing his climax.
"Stop..Natsume-san, I'm gonna come." Sasayan warned, trying to pull himself away from her.
"Isn't that the whole point of this?" Natsume asked, only pausing for a bit before continuing what she was doing.
Sasayan, accepting her logic without much thought, resigned to his fate and leaned back again, gripping the sleeping bed with both his hands and concentrating entirely on the sensation he was feeling in his genitals. He was watching her cleavage intently and from the angle he was at could almost see down the bikini top, which only heightened the sensations she was giving him with her hands. Soon he could feel his climax bubbling up from deep within his balls and managed to warn Natsume of his impeding climax.
"Gonna come! Natsume-san!" Sasayan cried out. Natsume only continued her efforts, using both hands to focus entirely on the shaft stroking rapidly up and down, occasionally tickling the slit where his precum was oozing out in copious amounts. This was too much for Sasayan and he felt his balls boil over feeling his pelvic muscles contracting in pleasure as his climax took a hold of him, shooting spurt after spurt of ejaculate into the air. He could feel his ejaculate landing on his shirt, on his stomach and on his thighs, soiling himself, but all this was overshadowed by the feeling of Natsume's hands on his penis stroking him all throughout his orgasm and the immense pleasure they were bringing him.
"It's more comfortable now." Was all Sasayan managed to breathe out as his orgasm subsided. Natsume had let go of him entirely and was watching him happily.
"That was exciting" Natsume commented, "although is it always this messy?" Natsume asked, looking at the globs of his ejaculate on his shirt and on his thighs, even a little bit had landed on her own thigh and she was experimentally prodding it.
"Yeh sorry..I usually use some tissues to clean it up," Sasayan replied looking around for some tissues, but realising he was in a tent with very few of his home comforts, he decided to take off his shirt as it was already soiled anyway, and first offering it to Natsume to use it to wipe herself off. Natsume refused, instead opting to examine the glob some more, so Sasayan shrugged his shoulders and proceeded to clean himself off. Little did he know that while Sasayan was doing this, Natsume was giving his ejaculate a few experimental tastes with a thoughtful expression on her face.
Natsume watched him wiping himself off for a bit before reaching for her clothes and sandals and crawling towards the tent entrance, unintentionally swaying her behind tantalisingly at Sasayan. "I think I better get going now." Natsume said as she undid the flap.
"Okay…" Sasayan replied awkwardly, not really knowing what else to say.
Natsume stood up outside the tent flap and looked back at the shirtless Sasayan watching her leave.
"You know Sasayan-kun…I wouldn't have minded if you had pushed me down." She murmured softly, and once she said that she turned to leave.
Sasayan felt all of his blood rise up to his head when he heard her say that, and watched her retreating figure as she walked away. He remembered her scantily clad behind wiggling as she crawled towards the tent entrance just moments ago, and made a decision right there and then.
"Wait, Natsume-san" Sasayan called out. Natsume turned her head back questioningly, the moonlight illuminating her face in a pearly glow, dazzling Sasayan.
"What is it?" she asked him softly.
"I..I want to push you down. " Sasayan murmured hesitantly, looking at her beautiful face. Natsume smiled, turned around, and walked back towards Sasayan's tent.
