A/N: Another lewd! This is a Klein x Asuna lewd because the friend of a harem protagonist needs some love too. For too long have they been regulated to comedic relief!
Warning: Contains Cheating and Netori, though not the stupid degrading one about turning the female lead into a bimbo. I can never get into Bimbo. I like my woman with at least some brain.
Ryoutarou Tsuboi, Kazuto Kirigaya, and Asuna Yuuki, known as Klein, Kirito, and Asuna respectively, were spending a warm summer day at Ryoutarou's place outside of their favorite Virtual Reality game. There were supposed to be more people present, but everyone either left already or was too busy to make it.
Eventually, it was time for the couple to head home too. They left hand in hand, laughing and joking together.
"Oh, I forgot my phone at Tsuboi-kun's place. I'm gonna go back and get it. I'll call for a ride so you don't have to wait for me," Asuna said, stopping in her tracks.
"I don't mind waiting. I'll walk you back to the apartment," Kazuto said, stopping alongside her.
"No, no. You're going to miss the train if you don't hurry." Asuna smiled and pushed Kazuto forward. "If you're late, Suguha'll get angry, you know."
"Oh, well, if you're sure..." Kazuto agreed, reluctant to part with her but understanding that she was right. "Call me when you're home, okay?"
"Yeah, see you later."
Asuna gave him a quick kiss on the cheek. Kazuto's face flushed at the open affection. She smiled again and waved, then turned on her heels and walked back toward Tsuboi's home. Kazuto watched her retreating figure for a second before turning to leave without a second thought.
A few minutes after Kazuto and Asuna left, Ryoutarou heard knocking at his window. He opened it, and there she was, Asuna, with a mischievous smile on her face. She climbed through the window, and the moment her feet touched the floor, she pounced on Ryoutarou with a giggle. They fell onto the bed, their lips meeting without hesitation.
"I missed you, Klein," Asuna said after breaking away for air.
"You were here a few minutes ago," Ryoutarou said, his arms wrapped around Asuna's slender frame. She only called him Klein outside the game when she wanted to play around. It was their little "code" for when she wanted to have fun with him.
"That's different. I was with Kirito then, but now..." Asuna let her sentence trail off.
"It's just us," Ryoutarou finished. He knew what she meant, of course. His hand ran down her side, over her stomach, and under her skirt. He was surprised to find it bare of any underwear. "You really can't wait, can you?"
"Mmmm, I was feeling a bit needy today." Asuna kissed him again. They stayed that way for a while before Asuna's hand snuck up Ryoutarou's shirt, undoing his buttons one by one.
When she was done, she slipped her hand under his clothes, feeling his abs. They were defined but not overly muscular. She pulled the shirt over his head and threw it to the ground. She then pulled off her blouse and tossed it aside as well. Like her bottom, her top was bare underneath.
"Kinky~" Ryoutarou teased, bringing his fingers up to pinch at her nipples. They hardened under the touch. He took her left breast in his hand, squeezing gently and running his thumb over the tip. His other hand continued to caress her crotch, feeling her getting wetter with each passing minute.
Asuna moaned softly as Ryoutarou played with her body. Her hand began to unbutton his jeans, and he lifted his hips to let her pull them off. They soon joined the pile of clothes on the floor. Asuna brought her head down and kissed him on the lips again. Her tongue explored his mouth as her hand gripped his stiff member. She pumped him slowly but firmly.
Ryoutarou broke the kiss and started sucking on her neck. His teeth grazed her delicate skin, and she let out a stifled cry. His tongue flicked out over the area where he bit, and then he licked her neck and moved up to her ear.
"I still remember you protesting when we first did this, A-su-na," Ryoutarou whispered into her ear. Asuna trembled at the way he spoke her name.
"Shut up," Asuna replied with a blush and pout. She tightened her grip on Ryoutarou's shaft and began stroking him faster. "I was so angry with you. I just started dating Kazuto, and you raped me."
"And yet here you are, stroking my cock and letting me mark you—"
Asuna stopped moving her hand and pushed Ryoutarou completely against the bed. She undid her skirt and kicked it off along with her shoes before straddling him.
"—when did it change, I wonder?" Ryoutarou finished.
Asuna put on a thinking face as she started grinding her bare crotch against Ryoutarou's member.
"I don't know. Maybe it was after that time you took me at school, or after you won the tournament and made me your "prize" for a day, or perhaps it was from the thrill that time you made me suck you off while you were talking with Kazuto. Or maybe..." As she listed each incident off, her face grew more flushed with lust, her breathing becoming heavier. "...maybe it was when you stuffed your fat cock inside of me for the first time outside the game and made me cum more times than I could count."
"So since the beginning, then," Ryoutarou said, moving his hands to Asuna's waist and groping her rear. His fingers dug into the flesh of her firm ass, and he lifted her up.
"Maybe~" Asuna replied, sticking her tongue out in a cute way. She gripped Ryoutarou's member in one hand and guided it to her wet opening.
"All I know is that I can never get enough of this," she said as she lowered herself onto his cock. She gasped and closed her eyes as the familiar sensation filled her up. "You feel so good, Klein..."
Asuna moved her hips in a slow rhythm as Ryoutarou kept his hold on her ass. Her hands rested on his chest as she began to pick up her pace. She could feel his hot cock sliding in and out of her folds as she bounced on his lap.
"Heeeehhh...aaah...so good, so good, Klein...aahn..."
Ryoutarou smiled at the sight of Asuna enjoying herself. He watched the bounce of her breasts, felt the heat of her body, heard her soft moans, and smelled her sweet scent. He knew he would never grow tired of this. He thrust upwards into her as she came down on his cock, and Asuna gasped loudly.
"Ahhn...Kleiiiiiiiin...haahn!" Asuna was overcome with ecstasy as she felt the tip of his cock push against the entrance to her womb. She let out a long, high-pitched moan. His cock stretched her open, pressing against her inner walls. It felt so good that it took all of her willpower not to cum right there.
"You're so hot, A-su-na," Ryoutarou said with a husky voice. His fingers dug into her ass again as he pulled her down onto him.
She shivered at the sound of her name on his lips. She leaned against him and rested her head on his chest as he lifted her ass up and started thrusting into her.
"Ah-ah-ah-ah-ahh! Klein-ah! Klein-ah!" Asuna could only moan as her body was racked with pleasure. She felt a tingling sensation in the pit of her stomach, growing hotter with every movement. "I- OOOOOHHHhhhh!"
Asuna couldn't help herself as she climaxed. Her body shuddered as a powerful orgasm washed over her, her juices flowing out onto Ryoutarou's member. Ryoutarou held her close and thrust into her a few more times before stopping to let her recover.
Then, right as she stopped shaking, he flipped her over onto her back, captured her lips in a kiss, and began pounding her again. Asuna broke away to let out a startled cry.
"Ha-ahhh! Haaaaa-aaaahn!" Asuna clung to Ryoutarou as he started pounding her again. "K-Kleiiiin! I-I...aahn!"
Asuna could do little else but cling to Ryoutarou as he ravaged her for what felt like hours. She let out a squeal when he pounded into her especially hard. Her fingers dug into his back as he continued to thrust into her. She was being mercilessly pounded by this beast of a man, and she loved every second of it.
"I'm going to fill you up with my seed, Asuna," Ryoutarou growled in her ear. "I'm going to pump so much of it into your womb that you'll be pregnant before the day is over."
"Ngh-aaaaah!" Asuna cried out at the thought, her body on fire with arousal.
"You like that idea, don't you? I can feel you getting tighter." Ryoutarou gripped her ass harder as he continued his pounding.
"N-no! I...aahhn! c-can't...a-a-ahhhn!" Despite her protest, her legs were wrapped tightly around Ryoutarou's waist, not letting him pull away. She wanted his cock so bad that she couldn't help herself.
"Here it comes..." Ryoutarou grunted as he felt his orgasm approaching. He pushed into her one last time, pushing against the entrance to her womb, and unloaded into her.
Asuna cried out as she felt his hot cum flood her insides. She couldn't help herself and she came with him, her inner walls clamping down on his shaft as if trying to keep every drop of his seed inside of her.
She was drenched with sweat as they both panted, exhausted from the sex.
"Ah-ah...ah...haaa..." Asuna's eyes fluttered open as she came down from her high. She leveled a glare at Ryoutarou without any heat. "I hate you...so much..."
Ryoutarou chuckled and kissed her lightly before rolling off of her and onto the bed. "Love you too."
"Tsk...I hate that about you too." Asuna turned on her side and scooted close to him, resting her head on his shoulder. Ryoutarou wrapped his arm around her and pulled her closer.
They sat in comfortable silence for a few minutes before Asuna spoke up.
"I mean it. I hate you. I hate the way you treat me. I hate how you make me feel. I hate how much I want you. I hate the fact that I'm falling..."
Ryoutarou said nothing and just held her tightly. He knew better than to respond when she spoke like this. He waited patiently until she was done.
"..." Asuna stopped whatever it was she was going to say and snuggled into him. She felt that if she continued, she wouldn't be able to turn back, that she could no longer lie to herself and say this was only a fling. Her fingers intertwined with his and she squeezed them softly. She was silent for a few seconds before speaking up again.
"I love Kazuto. I love him, not you. I'm dating him, not you. I'm just...letting you do this because it feels so good, but I can never love you the way I love him." She told him, but to him, it sounded like she was trying to convince herself. She nuzzled up against him again and sighed. "I don't know why you're so obsessed with me, but I just want you to know that."
"I know," Ryoutarou said, resting his chin on her head. "Whatever you decide in the future, I'll support you."
Asuna stayed silent.
They stayed that way for a while before she broke away from him.
"I should get going soon. It's getting late. Kazuto might get worried if I don't call him soon," Asuna said.
Ryoutarou pulled her into bed.
"Then call him. That doesn't mean you need to leave. Besides, he has plenty of girls to worry about right now."
Everyone knew about the dozens of girls pinning after Kazuto, even in their group alone. He wouldn't have time to worry about Asuna, not unless the girl disappeared for days on end or something similar.
"Tsk. I hate you. You're a terrible man," Asuna said, but she didn't resist him and instead snuggled close to him, resting her head on his chest.
Eventually, she did call Kazuto... in the middle of another session because he "forced" her to, but she stayed the night with him regardless.
