Notes See the end of the work for notes “Hey Mob-kun, hang back will you?” Shigeo looked up from the free weight he was struggling to lift, attempting to make his way to the rack. A bead of sweat rolled down the side of his face, his chin, caught on his white shirt and blossomed. “What is it, Tome-san?” His arms were shaking under the meager 5kg weight and blessed Hiroshi took it from him and put it in its place. “Just wanna talk to you for a second,” the girl said, her legs kicked up onto the table, crossed over one another. Tome flipped a page in her magazine, not looking at Shigeo or anyone else. The other members of the Telepathy Club were already packing their bags, slinging them on, cleaning up snacks, wrapping up their DS and Switch chargers. Shigeo made a small sound of confirmation and made his way over to where he and the other Body Improvement Club members had settled their bags. He had to set Onigawara’s aside, to which he got a nervous “Oi!” from the boy who was still so touchy, so gun shy, so scared, but he was able to dig around and find his cellphone with some ease. Squatting on overworked legs, Shigeo flipped it open and typed a quick text to the top of his few contacts. Shishou, something has come up at school. I’m going to be late. I’ll let you know when I’m leaving. Shigeo remained in his squatting position, waiting for Reigen’s approval. The Telepathy Club members were the first to leave, wishing Shigeo a good day as they passed, which he returned without looking up from his small screen. The Body Improvement Club continued to clean up around him, wiping down equipment and making sure everything was in its proper place. Musashi was the last to finally trail out, vacuuming up the crumbs the Telepathy Club left under the table. After one of the longest waits Shigeo had ever had to endure when it came to his master speaking, just as he was trying to formulate a way to politely reject Tome’s offer of one-on-one time, Reigen replied. Yeah, no problem. It’s slow today anyway. He’d been sleeping then. Shigeo closed his phone and put it back in his bag, standing on weak legs, his knees almost giving out, threatening to collapse him back to the floor. Musashi grabbed his arm as he passed, helping Shigeo steady himself as his blood pumped back to his dizzy head. “Careful, Kageyama-kun,” he said good naturedly, offering Shigeo a large, warm smile. Shigeo returned it, grateful to his friend who never judged him, always supportive and pushing him in a positive way. Musashi reached behind Shigeo and picked up his own bag, holding it away from his sweaty body. Shigeo knew the other club members typically went to the gym for a quick shower and change, and in the periphery of his mind, Shigeo longed to join them and shake the smell off. “Have a good afternoon, both of you.” Musashi was gone after that, leaving Shigeo and Tome alone in the small, shared club room. When Shigeo turned around to join Tome at the table, he jumped with a startled sound to find her standing right behind him, magazine discarded. “Uh- um- I-I,” Shigeo attempted. “Wh-…” “I wanted to talk to you about something personal,” Tome said, a fist on her hip, cocked to the side. She wore the same bored, passive expression she usually did, her voice carrying the same deathly serious tone as when she talked about espers and aliens and government conspiracies. She pointed straight up, and Shigeo looked. When he saw nothing, he struggled to figure out if she was talking about space again or if she was just gesticulating. When she then pointed at Shigeo, head lolling to the side, he realized it was the later. Blunt as always, Tome asked: “Do you touch yourself?” With a choked sound, Shigeo felt an electric shock run through him. His hair shot straight up before falling back down to smack against his heated face. He thought, feared, for a moment, he was going to pass out and ??? would take over to save him from this situation in a way that would lack more tact than if Shigeo had been left to handle it alone. As Shigeo fumbled for words, Tome continued. “It’s fine,” Shigeo knew it was fine, but the issue was in her asking! So boldly and in a public setting no less! “I asked because I wanted to know if you ever thought about having someone else help out.” Shigeo wasn’t very good at reading situations, but Tome didn’t need to explain any further for him to understand what she was going towards. He covered his burning face with both hands, hair bobbing gently at just above his ears. He could hear the free weights rattling in their rack. “Have you ever heard of something called ‘friends with benefits’?” Truthfully, Shigeo shook his head, still hiding behind his hands. He thought friendship was the benefit, the benefit of braving social situations, of putting himself out there, of pushing himself to grow. In exchange for his hard work, he made friends. Clearly there were still many things about society he didn’t fully understand. Tome clicked her tongue and Shigeo heard a rustle of fabric. When he peeked nervously, he saw that she had simply dropped her arm, straightening up a bit. She was older than him, more comfortable with herself, and apparently her body, but not by much. Shigeo chanced a glance up to her face and saw a blush forming on her own cheeks. The sight helped release some of his nerves and he didn’t notice that the window had been rattling in its pane until it stopped. “Right,” Tome said, clearing her throat. She found Shigeo’s single eye from behind his long, skinny fingers, and met his gaze. “It’s when friends who don’t have feelings for each other do-“ and here she fumbled, voice cracking on the next word, “s-stuff together. Just for fun, not for anything else. Just because- because…” she cleared her throat again, finally averting her gaze. Her fist remained at her mouth, hiding. “Because they trust each other.” “Y-you-“ Shigeo’s voice came out hoarse, broken, an octave higher than usual, “you want to do s-stuff like that….wi-with me?” His hands were shaking. Was this real? Tome’s face reddened further. “Only if you want to,” the words came out rushed. She still wasn’t looking at him. “I want to- to try that sort of thing, but you’re the only one-“ her voice dropped, quiet, Shigeo had to strain to hear, “the only one I-…I trust with it.” There was a long pause in which Shigeo didn’t know it was his turn to speak and he felt his heart skip guiltily when Tome took it the wrong way. “Like I said-!” She was back to her usual overbearing yet somehow still passive demeanor. She made his head spin; it was like talking to a weird combination of Reigen and Ritsu. “It’s only if you want to! We don’t have to do anything you’re not comfortable with. Sorry I asked, I just figured…” she trailed off, trying to get a read on a face Shigeo wouldn’t show. Her eyes darted up and he was made keenly aware that his hair was still floating. “Well. Whatever, doesn’t matter.” Tome turned away from him, going back to her original spot at the table. Stooping down, she grabbed the strap of her bag from where at some point in the day it had fallen underneath the table. It wasn’t until she was finished packing up her things and adjusting the strap on her shoulder that Shigeo realized he’d just been silently standing there for upwards of five minutes. “Okay!” he blurt out. Tome looked up from her backpack strap, embarrassed flush still dusting her cheeks. There was a thick air hanging between them, an air Shigeo had quickly learned was what awkward felt like. “What?” “Okay,” Shigeo said a bit more secure. Slowly, he lowered his hands, worrying his bottom lip and averting his gaze. “Okay to- for us- to you know…” he fumbled, fingers twisting together at his chest, in his shirt. Tome didn’t finish the thought for him and he realized he was going to have to make himself clear. “We can…try doing stuff like that. T-…together.” For a long, long moment nothing happened. Shigeo was nervous that he had inadvertently ruined something. That in waiting too long to accept, he had violated something unspoken and fragile between him and his friend. He feared that maybe this heavy air would never leave, that they would be tainted. He didn’t think so, but there were claws against the lobes of his brain, critical. The longer Tome went just staring at him, the more and more the tension felt like spoiled clothes, sour with dried milk. The more the rattling of the free weights, and now the window again, sounded like Kageyama-kun don’t you like me. The more the silence, the inaction, felt like watching the blood of his only friend splatter under white sneakers, felt like gravel digging into his face, palms, felt like the mewls of a cat— “You’re shaking pretty bad.” Tome’s voice was cool, soothing. Her hands were soft as they ran against his own. “We don’t have to.” “It’s not that,” Shigeo choked out, relieved to see that when he traveled far, far away from this moment, she had set her bag down and moved closer again. “I- it’s not that…” the words were softer the second time, his eyes on her hands, grounding. He hadn’t messed up, he hadn’t ruined it, he wasn’t in trouble, not yet at least. She was waiting again, and this time Shigeo realized it was his turn. “I was just scared.” He swallowed. “I-I thought you were mad at me.” She snorted, rolling her eyes, opening her mouth to speak, but Shigeo knew that if he stopped now he wouldn’t recollect the courage to finish. “I want to. T-to try at least.” Heart wrenching pause before: “Okay.” The word was a whisper and Shigeo lifted his eyes too late to not be caught off guard by her leaning in closer. She wasn’t that much taller than him, but in that moment, he felt as though he was standing at the foot of a mountain. His tongue dart out to lick his lips the same moment she tried to press against them and she wound up kissing his tongue. Tome laughed, pulling back only a few inches. “Wow.” At some point she had pulled his hands from his shirt, from each other, and was holding them between them. “Well they do say first kisses are usually pretty awkward but that was…” Shigeo felt shame run through his already cold blood, heard something fall with a clatter behind him. Tome didn’t even look, too used to his powers by now. Wanting to make it up to her he tried again, letting his lips settle on hers. Was this still her first kiss or did he ruin that for her? Did it even count if they didn’t have feelings for each other? Tome’s hand at the back of his head kept him from spiraling too far outside of himself. Even though she was pulling him up, pulling him closer, his now freed hand hovering in mid-air, suspended, unsure, Tome didn’t deepen the kiss. It remained chaste, if more firm. He didn’t know if he was allowed to touch her. But he found that it didn’t matter just yet because he soon had to pull away, gasping for breath. Despite her previously firm hold on his head, she allowed him to move without much resistance. “Jeez, Mob-kun,” she said, “you’re supposed to breathe out of your nose.” Shigeo was left with the shocking worry that maybe that hadn’t been her first kiss. She was a year ahead of him, she did have a fair number of friends in Shigeo’s eyes. Maybe she’d messed around with people before. The thought of her in this very room, with another Telepathy Club member, or at a small party, shy and awkward and chiding some other boy- some other girl maybe even- Shigeo couldn’t think about that. Tsubome was always the first girl his mind conjured up, even if he was still reeling from his rejection. The thought of Tome and Tsubome kissing as part of some game or dare at those parties Ritsu warned him about where kids would drink alcohol and smoke- It was getting him too hot, he had to lock that away. He came back down from the clouds at the gentle pat pat of Tome’s hand against his cheek. “You gonna live?” Shigeo tried to say “yes” but it came out as a throaty, guttural grunt. Tome laughed again, shifting, and Shigeo realized they were still pulled up close to each other. And that made him realize, with fear and shame and embarrassment, that maybe the kissing, maybe the thought of Tome and Tsubome together, had gotten him a little hotter than he had realized. His first instinct was to pull back, drop to the ground, and beg for forgiveness, but at the first twitch of his body Tome held more firmly onto him. “It’s okay,” she said, “isn’t that what we’re trying out?” Shigeo’s head was spinning, he couldn’t see straight, he couldn’t believe Tome wasn’t disgusted by him, wasn’t pushing him violently away, wasn’t running off to tell everyone about what a pervert he was, wasn’t telling the other boys he attacked her, wasn’t riling them up to jump him in the bathroom, in the hallway, in the parking lot, after school between classes walking home— “Can I touch it?” “A-ah-?” Tome motioned between them, trying to keep her face passive but her blush giving her away. “Can I touch it?” “Ngh-“ The inflection of whatever word he’d tried to sputter out was enough for Tome and she slowly, so slowly, reached her hand down and pressed against the erection straining against the front of Shigeo’s gym shorts. He gasped, hips stuttering, and Tome’s hand in his hair kept him grounded, kept him from embarrassing himself too much. At first, she was only pressing the heel of her hand against it, fingers wrapped loosely around his thigh, but the longer they stood the more confident she grew in his consent and then Shigeo really thought he was about to die because there was a girl holding his dick. Tome gave a few loose-fisted strokes, humming softly. “I thought they were bigger than this.” Shigeo was too busy seeing stars to feel insulted. She didn’t stop stroking him, growing more confident as he doubled over, leaning his forehead against her shoulder, panting heavily. “I guess it gets bigger as you grow, like tits.” Shigeo opened his eyes blearily, realizing how close he was to her tits. “Ca-can I-?” “Yeah go ahead.” Shigeo reached up with the hand that Tome had first left dangling between them, not even realizing he’d just been standing in the position she left him in like a total freak. He cupped her breast, head spinning again as he gave a gentle squeeze. Tome’s boobs were nothing to write home about, smaller than even Shigeo’s small hand, but god it was a boob and it was a girl’s boob and it was real and Shigeo thought he was dreaming. As Shigeo gave a few emboldened squeezes, Tome sucked in a breath and Shigeo realized that Tome was not wearing a bra. He realized this because, as his fingers slipped over the soft cotton of her school uniform, he felt her nipple pressing firm against him. He really was going to pass out. Instead of that, however, his knees buckled and thankfully he was leaning mostly against Tome. She was able to catch him easily, hissing in annoyance. “Come on, Mob,” she chided, “haven’t you ever watched porn before?” He had but he didn’t think he had the strength to defend himself. “You’re not being sexy at all right now.” Tome practically dragged him over to the club table, Shigeo’s legs kicking uselessly under him as his feet tried to find purchase on the waxed hard wood. She rest herself against the edge, not quite sitting but not quite standing, letting Shigeo recover from his boob-touch induced delirium. “Alright,” she grunted, patting her hand on his back and Shigeo hadn’t even realized she’d let go of his dick, “you clearly don’t know what you’re doing.” Sitting up, Shigeo blurted out: “Have you had sex before, Tome-san?!” His hair was standing completely on end again, and in his periphery he could see things floating aimlessly about the room. “What?! No! Of course I haven’t! God, Mob, I just know a thing or two!” Get a clue get a clue get a clue “Come on I didn’t mean in like that come here- Look I’ll help you out okay, I’ll tell you what to do and by the time we’re done here you’ll be an expert! As your senpai and club president it’s my duty to teach you everything I know!” “I’m not a part of Telepathy Club, Tome-sa-“ “That’s not the point!” Tome beat her chest with her fist, pumping herself up in a way that matched her smug, determined expression, careful of Shigeo who she had tucked up against her. “The point is, I’m going to teach you so you don’t embarrass yourself when you get with a girl you’re actually trying to impress!” “O-oh…” Shigeo’s hand fidgeted against Tome’s shirt. “But I am trying to impress you.” “Yeah well,” Tome returned to her usual expression, letting her arm drop, “you’re not doing a very good job.” Tome shifted them, making Shigeo support his own weight for the first time in what felt to Shigeo like ages, tangling their legs together and having Shigeo lean his hips against hers. “There, now j-just-“ She took hold of his hand, hesitating, nervous, the blush was back. With dawning realization, Shigeo’s eyes widened. Tome had touched him, now he was going to touch her. His throat tightened up, all the blood in his body splitting between his face and his dick, which he noted with absolute horror was pressed up against Tome’s smooth, pale thigh, right below where her skirt ended. His fingers twitched around Tome’s hand, both tense and just on the brink of losing composure. Shigeo only had a barely working understanding regarding vaginas. He’d seen them in porn and in his sexual health textbooks, but it wasn’t like either of those sources gave a play-by-play demonstration of how you were supposed to jerk a girl off. Dicks were simple, easy, just grab it and hang on. Shigeo could do that, once he’d learned how to reel in his powers enough to handle it, at least. And this didn’t have anything to do with being an adult, so Shishou hadn’t taught him, and this didn’t have anything to do with being socially apt, so Ritsu hadn’t taught him, and this didn’t have anything to do with being God, so Dimple hadn’t taught him, so when Shigeo mustered up all courage he could scrape from within his heart and stuck his hand under Tome’s skirt, pressing against her soft, damp underwear, he had no idea where to begin. Tome let out a startled yelp, hips stuttering against Shigeo’s. His first instinct was to yank his hand away, and he would have been able to if Tome didn’t have an iron grip on his wrist. “B-bold,” she stuttered in such a way it almost sounded chiding, but Shigeo could tell by the look on her face the tone was directed at herself. Shigeo didn’t know if it was funny or insulting that Tome felt bested by him of all people. But her eyes were closed and her jaw was jutting out to hide how her lips were trembling and she continued to keep his hand there, so he decided to just let it go and focus on the fact he was up a girl’s skirt. Keeping a firm grip on his hand, Tome adjusted herself against him, having to open her eyes a crack as she did so but making sure to keep her gaze downcast. Shigeo felt the softness of her underwear against his skin, feeling the way it caught against one of his nails, how damp and warm it was. He was panting, rocking his hips back against hers, hand gripping tight against the table. “Right there,” Tome said breathlessly, positioning Shigeo’s hand where she wanted it. “Just, you know-“ her eyes finally flit back up to his, and she could see through the half-lidded haze he was less present than he normally was, “just- rub it.” So Shigeo rubbed it. The keen Tome let out as she arched backwards into the desk, twisting one leg around one of Shigeo’s, grip tightening around his wrist- the keen was enough to cause Shigeo to snap his head to the club room door. He knew the student counsel was roaming around, making sure students were gone and club rooms were properly cleaned. The student counsel. God. Ritsu. What would his little brother say if he caught him in such a compromising position? He was brought back to the girl holding him in position when the nails of her free hand dug into the fat of his arm. There was a flicker of other nails, perfectly manicured and painted, neat and just long enough, digging into clothing, skin, hair, but Tome sounded so good and felt so good and smelled so good that the memory of Minori was gone as quickly as it came. Shigeo bent downwards against her, feeling her chest heaving against his. He was panting against her neck, warm and wet, sucking back in his own stale breath. The table below them was shuddering and jumping with every twitch of Tome’s body as Shigeo rubbed her off, humped against her sharp, jutting hip bone. It was Shigeo’s turn to yelp out in surprise as a shaking hand wrapped around his erection. The hold was too firm and uncoordinated (and that was saying something considering it had been well established Shigeo was not an expert when it came to sex), but he wasn’t complaining. In fact, he proved that Tome’s inexperienced jerking was greatly appreciated by the way he moaned her name against the damp spot on her school uniform. In addition to his lacking sexual prowess, Shigeo was also not exactly shooting massive, thick loads. But that didn’t mean he totally appreciated the mess he made in his underwear. Underwear he didn’t have a fresh change of. Underwear he was going to have to put back on after his shower, wear during work, and walk all the way back home in. Maybe even though dinner, if Reigen decided he didn’t want to be alone. Even still, Shigeo made absolutely no attempt to pull away from Tome’s hand as he came, stilling every movement except the weak, distracted pawing at her underwear. “Senpai,” he whimpered when he’d finally managed to suck in enough breath. “You’re doing so good, Mob-kun,” Tome panted, one hand rubbing soothingly at Shigeo’s back. She was still panting, squirming. Shigeo hadn’t noticed just how sweaty he was until now, how badly he must stink. “Come on, keep going, I’m- I’m almost there.” Shigeo tried to steady himself, sitting up so his weight would be off of her and he wouldn’t be tempted to grope at her boobs any more. He placed his weight on one arm, shaky from the work out and the waves of pleasure still occasionally drifting through him. The right thing to do would be to keep his eyes open, to look at her and watch for her reactions, to learn how to do this right, to know if she really came or if she faked it for his ego like he heard some boys in his class whispering about. Shigeo knew himself better than that, though, so he felt barely any shame when not even five seconds into that he squeezed his eyes shut, face hot. It only took a few more minutes of careful, steady rubbing before Tome finally reached her own peak. Once again she was arching up into Shigeo, gripping him tight, coiling around him. He’d always been a mouse in her grasp. Shigeo learned that he didn’t need his eyes to know this; it was like sensing an aura. Not literally, of course, because Tome was completely normal, perfectly typical. But he could feel the minute ways the hand on his back twitched, the way her legs tightened and loosened around his, how her body was winding up, hips instinctually twitching to guide him into a pattern, a rhythm. He could hear how her voice hitched, how she tried to stifle moans that snuck out half way as sputtering little sighs and gasps, trying not to pride himself with her humming Mm’s that maybe could have possibly been the start of his well-warn nickname. Using these subtle but powerful cues, Shigeo knew that he’d been able to do what some of the other boys claimed was totally impossible. Tome came back to herself much more quickly than he had, sitting up and looking at him, tired. “Did I do it?” “Yeah isn’t it obvious.” “No, I mean,” Shigeo chewed his lower lip, glancing away for only a second, “did I impress you?” Tome stared at him quizzically for a beat, two, before Shigeo saw realization flash in her eyes. She laughed and ruffled his hair. He hadn’t noticed it had bent back to the will of gravity until that moment. “Yeah,” she said, “you did.” They didn’t jump back away from each other like they’d been burnt, and there was no awkward disengaging. Tome and Shigeo simply untangled themselves fluid and natural, an organic end to a forced coupling. Tome returned to her backpack, straightening up her uniform and looking for stains. Shigeo went to his backpack and gym bag, riffling through the clothes, desperate to see if he’d forgotten to unpack what he’d warn the previous day with no luck. Shigeo sighed, resigned to his come-sticky fate. Maybe if it was really as slow as Reigen indicated he’d be able to go home early. Maybe skip all together. “That was nice,” Tome said from somewhere above him. Shigeo stood up, taking a bag in each hand. “Yeah, it was.” The two smiled at one another and with a quiet, almost shy set of goodbyes, they turned in opposite directions out the door.
