Teru has sharp teeth. Notes My condolences to everyone except the handful of people who explicitly asked for this See the end of the work for more notes “Ah, Rei, take the meat off the heat,” Teru called from in front of his television. “Got it,” she responded, quickly turning off the stove and moving the small skillet off the hot burner. She retrieved two bowls stacked on the side of the countertop. Teru pushed himself to his feet and walked to join her at the kitchenette. “How’s the rice?” he asked from behind her. “It still needs a few more minutes,” she answered. “The eggs might get a little more cooked than we thought.” “Ahh, I didn’t get the timing quite perfect,” he admitted, reaching past her to lift the lid from the oyakodon. Rei stiffened as Teru’s other hand perched on her waist, and his solid torso pressed against her back with the reach. “Hey, Rei,” he called after setting the lid down on the countertop. “Yeah?” “Thanks for coming over,” he said. Both arms now wrapped around her in a hug, and he gave her a light squeeze. Rei already felt her heart overreacting to the gesture. They had gone on dates before, had held hands and even shared small kisses when no one was looking. But this was their first private date, and Rei was now acutely aware of their freedom to show more affection than would be polite in public. “I’m happy to be here,” she answered sincerely. Teru squeezed a little tighter and nuzzled his face into the crook of her neck, drawing a giggle out of her. “Teru, that tickles,” she scolded playfully, patting his hair. “How about something to counter the tickle?” he asked. Before Rei could ask him what he meant, she felt a stab of teeth on her earlobe. She yelped and winced, startling Teru out of the bite. “Sorry, sorry!” he quickly apologized, eyeing her ear. “My teeth are a little sharp,” he admitted. “That hurt.” “I know. Here, let me kiss it.” Without waiting for her response, he kissed her bitten ear lobe in apology for getting too carried away. The gesture was much more tingly than Rei was accustomed to feeling, but fortunately she could blame any redness in her face on the heat of the stove. When she noticed Teru leaning over her shoulder, smiling softly, trying to gauge her reaction, she couldn’t help returning a smile. Upon seeing this, Teru let his smile widen to reveal the crooked teeth that had just betrayed her. That Teru had slightly crooked teeth was oddly endearing when Rei first noticed it. It gave a bit of human imperfection to the otherwise perfect boy, and as a result only enhanced his charm. It wasn’t until just now that she learned that this cute feature could be a little dangerous when wielded carelessly. “Go ahead and get comfortable,” he told Rei. “I’ll put the food together.” She gave an agreeable hum as he loosened his hold. Being short a few furniture items in the small apartment, Teru only had his bed to offer as seating. Rei didn’t mind this so much as she did the DVD menu showing an ominously dark shot of a woman’s back hiding a knife. “You know I can’t really do scary movies,” Rei reminded Teru. She couldn’t have explained it perfectly if she tried, but she did once tell Teru about how the rollercoasters of upsetting events in horror movies did something to her powers that left her with a clinging sense of dread whenever she tried to watch them. “Don’t worry, it’s not really scary,” Teru reassured from the kitchenette. “It’s more of a suspenseful drama.” “Okay,” she surrendered skeptically. Teru soon came to join Rei on the bed, two bowls of oyakodon in hand. He handed her a bowl and sat to start the dinner and movie together. Once they were settled, he flipped the light switch off with telekinesis. The movie followed the yandere-girlfriend theme, focusing on an exchange college student to America who got swept away by the party life and entered a relationship with a girl he met while out drinking. At the very least, they were done eating and Teru had already sent their dishes floating to the sink by the time Rei started experiencing the vague unpleasant feeling she got when watching scary movies. She was unable to hold back an uncomfortable groan at one point when the protagonist’s professor appeared on screen. “How are you holding up?” Teru asked her. “She’s going to get the professor, isn’t she?” Rei asked. “It feels bad every time he shows up.” “They don’t show anything gory on screen,” he said without directly answering. “Can we watch something else? This is starting to stress me out.” “Hey, there’s less than forty minutes left, and a good five of that is credits.” He slipped his hand into hers. “You can squeeze my hand or look away if it gets scary,” he offered. His other arm reached around her back to rub her arm comfortingly. She surrendered with a sigh. Rei toughed it out for the remainder of the movie, insisting to herself that Teru seemed to really like having someone to watch movies with, and so she should be an accommodating girlfriend and deal with it. It was just a movie, she told herself; no one was really getting hurt, and so she could deal with her fiction-rattled clairvoyance acting up a little bit. Still, it would have been a lie to say she wasn’t completely relieved when credits started to appear on the screen. Teru tilted his head to get a better view of her face. “I’m okay,” she told him. He began to rub her arm again. “Thanks for watching with me,” he said quietly. He hugged her into his chest and pecked a kiss onto her temple. Rei easily pressed into the calming hold, more grateful for the comfort than embarrassed for needing it in the first place. She supposed one advantage to having a psychic boyfriend was having him understand that some things affected her a little differently, yet he didn’t blame her for it. He tilted her chin up. “Hey. I’m sorry if the movie bothered you. I’ll let you pick next time, okay?” She couldn’t resist accepting the apology. “Okay,” she agreed, a smile breaking through her defenses. Teru mirrored the expression. He descended for another kiss, this time on the lips. She took a sharp breath as he lingered, and his hand lifted to her cheek. “I’ll make it up to you now too if you want.” Rei blinked. Teru’s face was dimly lit by the rolling credits on the TV, expression visibly soft in the dark apartment. The comforting sight started to tangle with the leftover sense of dread. “Make it up how?” she asked. Teru was quiet as his hand lowered from Rei’s cheek, down to her thigh, and gave a soft squeeze. The two-armed hold now left her feeling trapped, even while she knew this was Teru, her boyfriend, holding her close. He gave a coy tilt of his head, seeming nothing but pleased with Rei’s passive stillness. “Something you’ll like,” he finally answered. He kissed her before she could give a proper response. Rei continued to try to relax in Teru’s hold, but then his hand crossed over to the inside of her thigh, forcing her to flinch. Her own hand lifted to press against his chest, and she pulled away from the kiss. “Wait,” she said. She looked away to the floor beside them. “I don’t think I’m ready to do anything like that.” Teru shushed her quietly. “You don’t have to do anything.” He gave her inner thigh another squeeze. She felt the tension between her legs responding to his touch, and she pressed them together. “Just lay back and enjoy it,” he whispered into her ear. Rei didn't answer. “Hey, look.” She met his eyes. “It's nothing too serious if that's what you're worried about. I just want to do you a little favor.” He stuck his tongue out at her playfully, and she picked up the implication. “Um,” she stammered, looking away again, gaze landing on the DVD menu now back on the screen. Teru's hand giving her thigh one last squeeze took her attention from the knife-wielding actress before it moved under her shirt to feel her belly. The gently pulsing pressure down below made her instantly miss having that hand between her legs and too compliant when Teru requested a simple “Trust me” and nudged her down onto her back. Rei watched him situate himself above her. One knee found its place between her legs on the bed; an arm propped him while the other hand remained under her shirt. She was nervous. Teru had never taken things this far, nor had he ever been this insistent about anything less innocent than paying for lunch. As he descended to kiss her again, she figured in hindsight that this kind of thing was supposed to be expected if she agreed to be alone with a boy. She remained quiet as he trailed kisses down to her neck, and she yielded to him nudging her head to the side to better reveal the sensitive skin. Again, she was looking at that creepy DVD menu. She wished he had turned off the TV at least, the last thing she needed on top of her nervousness was the anxious feeling the sight gave her. At the same time, the thought of having no light source at all made her just as uneasy. “Ow!” Teru's tongue stroked the area where he had just given her a hard bite. He lifted enough to look at her face. “Sorry,” he offered, expression far more mischievous than apologetic. “I got a little excited again.” “It's okay,” Rei managed to say despite the lingering pain. He remained close. His hand slid up her torso to grope her breast through her bra. Rei watched him explore, watched him sit up to free both hands for lifting her shirt to the top of her chest. He hooked a finger under the front of her bra curiously. “It opens in the front?” he asked. “Oh. Yeah,” Rei answered. “Here,” she continued, hands reaching to undo the clasp. “Hey, hey, don't worry about it,” Teru interrupted, taking hold of one of her hands. She stilled, allowing him to bring her captured hand to his lips and kiss her knuckles. “Like I said, you don't have to do a thing.” He released her hand. She lowered them both back to her sides. “Okay.” Teru eyed the front clasp of her bra. “I'm only wondering now, what did you have planned for the night?” Rei didn't know how to respond to the thinly-veiled indictment. So she said nothing and tried not to think so hard about how Teru knew how to open the clasp without assistance. He easily enveloped each of her breasts in one hand and groped. “I know they're small,” she said. “They're cute,” he corrected. His fingers pinched and played with her nipples. Rei closed her eyes, growing too uncomfortable to watch between her self-consciousness about her size and apprehension about having the entire situation pushed onto her. A sudden sense that she needed to interrupt him started to grab at her attention. Teru's lips pressed gently in the modest valley between her breasts, and whatever words she might have said to stop him caught in her throat. He was so intent, and she was sure he would only coax her back into submission anyway if she said anything. Teru chose a nipple to introduce to his mouth. Rei bit her own lip when she felt the wet warmth on her skin. He had been so strangely careless biting her tonight, and her trust wavered. She could feel the pointed tips of teeth lightly teasing the delicate flesh. He was being gentle now, and those irregular, sharper-than-average teeth actually felt kind of nice just grazing her skin. Rei loosed a moan that she hoped didn't sound too silly to communicate her preference for this more careful treatment from Teru's mouth. His tongue flicked her nipple before he switched sides. She kept her eyes closed. Teru suddenly bit down hard on her breast. Her head jerked up and she yelped. When she looked at Teru, he was staring at her with discomfiting fixation. “Teru, stop!” she cried out. Teru's teeth tightened on her flesh instead, pulling another startled sound from her. They raked her skin as he slowly lifted away from her breast. A final high-pitched sound left her when her nipple slipped out past his teeth. His fascinated stare moved from Rei's face to the impressions his teeth left in her skin. He dipped his head down to investigate the texture of the mistreated flesh with his lips. “That really hurt,” she told him, now fully understanding the urge she had a moment ago to try to interrupt him. She could still feel the edges of his teeth in her skin, even while his exploring lips brushed over that hurt area. Teru's fingertips replaced his lips caressing the teeth imprints on her breast. “A little pain can be enjoyable too, you know,” he said. “That was way too much,” she insisted. “I didn't like that at all.” He answered a reluctant “Okay.” His hand switched sides to give her a gentle squeeze. “What about this one?” “That one was okay,” she answered, now a little shyer. Teru smiled at the confession. He kissed her lips again before proceeding with an “Alright.” He lowered to her belly. His teeth grazed and lightly dug into the skin between kisses. She was self-conscious earlier about their perceived difference in experience, but now she wondered how much Teru was actually trying things for the first time. For all she knew, he might have had no idea how easily the points of his teeth sunk into her skin. She preferred that explanation over the possibility that he was knowingly hurting her. Teru was shifting now. He situated himself between Rei's legs, and he sat up on his knees to open the button of her pants. She watched silently as he worked them down her legs, folding her limbs upward, fingers delicately pushing both her jeans and panties up and off of her. He let them fall to the floor, and Rei instantly wished they were in the dark instead. Anxiety blossomed in her stomach at the sight of Teru looking down between her legs, and at the same time, she became hyper aware of how badly she was aching for attention. She looked at the wall. Teru noticed. He placed his hand on her belly, causing her to flinch. “Nervous?” he asked. She swallowed. “A little.” “It'll be okay,” he reassured, petting her. His hand continued downward past her navel, until it was sliding between arousal-slickened lips. “Rei,” he called, feigning shock. When she looked at him, he was pointing an impish grin at her. “You could have told me anytime,” he teased. She wasn't clever enough to think of a comeback. Teru's two fingers dipping inside of her robbed her of the clarity of mind to speak anyway, or for that matter, think anything more complex than “more.” They were gone far too soon, instead treating her to the sight of Teru sucking one and then the other, slowly and thoroughly, as if he couldn't dare wasting any of her taste. She stared up at him dumbly, still speechless over the sight after it had ended and he was descending to the mattress. He was spreading her lips. She didn’t know what to expect, but it certainly wasn’t the stinging intensity of his tongue being run over her exposed clit. She winced the first time, lifted her head the second, and called his name the third. He looked up at her, face not entirely readable in the dark from this angle, and in the middle of her saying “stop,” gave her one more overstimulating lick. Her face contorted. A smirk snuck onto Teru’s face while her eyes were shut. “Does anything hurt?” Teru asked, releasing the hold on her lips. “Um, not really,” Rei answered. “It’s-… I don’t know.” “Too much?” he asked. She nodded. “I think so.” “I’ll be gentler then. You can lay back down.” Some kind of apprehension seized her when she started to do so. She kept herself propped up instead and suggested, “Maybe we should try again another time.” Teru stroked the outside of her leg. “Don’t be discouraged, I won’t overdo it like that again,” he told her. He kissed her inner thigh. “It’s okay. Lay back down.” Rei stared down at him a moment longer. The repeated mishaps and her persistent feeling of aversion left her thinking that she really shouldn’t. But his hand glided up her belly, applying a gentle push along the way. “Trust me,” he told her again. The appeal melted away the little nerve Rei had to try to escape. She returned to her laid-back position on the mattress. She shut her eyes as she allowed him to resume. She felt his teeth on her skin first and tensed. Teru felt it; he petted the outside of her thigh, and she relaxed as he softly bit and suckled her lips and clit. Once again, this much milder graze of teeth was actually enjoyable in conjunction with the less direct contact. Still, something was missing. “Teru?” she called. “Hm?” She inhaled slowly. “Could you put your fingers in again?” He gave an affirmative hum before obliging. Rei took another deep breath after his two fingers were in and moving. It still wasn’t quite enough. “Could you put one more in?” A small chuckle sounded, and a third finger started to stretch her. Any remaining tension in her body melted under the combined sensations of Teru’s mouth toying with her clit and his fingers stroking inside her. She couldn’t decide on what sound she should make, and so settled on heavy breaths through her mouth. Teru chanced getting a little harder with his bites. Rei whimpered again upon registering something more distinctly painful, body beginning to squirm in place. Teru lifted his head from her, fingers still moving. “Too much?” he asked. “Um, actually,” Rei responded hesitantly, “that was actually… I kind of liked it.” He smirked. “Alright. You’re free to make a little noise, you know.” “I know.” She didn’t explain that she didn’t entirely know what sounds wouldn’t make her feel silly. “You already sound lovely down here,” he commented, twisting his fingers to sound off a louder squelch. Rei took an audible sip of air and arched up at the sensation. Teru returned to giving her the firm bites she was coming to enjoy. She clenched around his fingers. An unprompted foreboding hit her once more. She didn’t know what it was this time, and Teru’s fingers stroking her insides were far too absorbing for her to worry about it. Though his teeth stabbed enough to hurt, she found her reservation crumbling after confessing out loud to enjoying the pain level. He hooked his free arm around her thigh to hold her still. She tilted up to look at him, still squirming in his grasp. His eyes flicked up to hers briefly before shutting again. A punctuating bite made her jerk, and he gave a parting lick to continue looking at her. He seemed satisfied; the look on his face suddenly reminded her of the fear-like hesitation chafing at her mind. A whimper escaped her. Teru’s fingers never let up to give her a chance to think, and so she closed her eyes and let the sensation continue to climb to levels that were quickly becoming overwhelming. Her hands squeezed the sheets and she began to rock out of her own control. “Look at me, Rei,” he purred to her. Another high-pitched sound escaped her. She forced her eyes open on his command, but they focused on nothing. Control over her body had become a foreign concept. Her hips jerked, both urgent and aimless in their motion, powerless to stop or escape the tide Teru had singlehandedly brought crashing down on her. Teru’s head turned at some point in the midst of her lapse of thought. Rei was too far gone from reality to warn him before he made a vicious bite on her inner thigh. She moved before she could find words – hand suddenly on his head, pulling his hair, followed then by a cry to stop. He released the bite upon her plea, but his working fingers kept her from her senses. She folded forward, then fell back onto the bed. She reached down for his hand and took hold of his wrist. He insisted for a few more seconds, then freed her by withdrawing his fingers. Rei panted with her eyes closed. She waited for the remaining sensitivity to fade: the pain of being bitten, the intensity of her orgasm. She felt Teru’s tongue on the inside of her thigh. It pressed a deep, dull pain where the edges of his teeth must have bruised her, and it left a sharp sting where they broke her skin. She almost didn’t want to believe Teru would bite her so hard that she bled, but there was no other explanation for the sting of broken skin she felt when he kissed the bite area. “Close your eyes,” he said. “I’m turning on the light.” Rei did so, and the black behind her eyelids switched to a faintly overbearing orange. She blinked to adjust to the light before sitting up and looking down. Teru’s attention was still trained on the bite he had last given her. “I think this will leave a mark,” he said fondly. He stared at the dark red imprints on her thigh a moment longer before meeting Rei’s eyes. She also considered the unasked-for embellishment to her body. Teru’s eyes lowered to her chest for a moment. “Looks like I was just shy of leaving a mark up here though,” he commented. “It hurts a lot when you bite me that hard,” she told him. “I still really don’t like that.” “I see,” he said. Teru only continued to appear proud of himself. “You seemed to be adjusting, so I gave it one last try.” A little warning before he decided to “try” things would have been nicer. “Just. Please try to be more gentle at first,” she asked instead. “I will, I will,” he answered. “But it wasn’t all bad, was it? From what I saw, I think you liked getting hurt a little bit.” Rei looked at the wall. “Only when it was a little bit.” Teru got up to his knees. “Alright. Like I said, I’ll be more careful next time. Okay?” Rei nodded. “Okay.” He kissed her forehead. Rei didn’t immediately want to think about a next time. The thought gave her sixth sense a chill, though she offered no comment along this line as Teru gave her inner thigh a few last strokes with his finger and bid her to relax while he started on washing dishes.
