Shizuo knocked on the door. "Come in!" He heard from inside, his girlfriend's cheerful, bubbly voice rising over the low murmur of some kind of TV show. He opened the door and entered. She was waiting for him in Alex's dorm, which was already bad enough, but when he looked inside his mood got even worse when he saw them. Eun-ae, his girlfriend, was half-sitting, half-lying on the couch looking very comfortable as she smiled at him, taking her eyes off the TV in front of the couch. Too comfortable in fact, because her legs were completely bare and she wore only her frilly, pink panties and a T-shirt. It was pastel-pink, with some kind of cute animal print on the front. A dog, or maybe a bear. He noticed her nipples subtly poking through her shirt, and realized she wasn't wearing a bra!

Normally he wouldn't mind seeing his girlfriend dressed so in a private setting, but they were not alone. And sitting beside her was Alex, the one Shizuo hated the most. He was an old friend of Eun-ae and a complete bastard, with a cocky grin plastered on his face as he draped one arm around her and she rested her head against him. He was tall too, almost dwarfing Shizuo’s petite girlfriend, and he was wearing only a white shirt that was tight on his chest, showing off his impressive physique, and a pair of white underwear. And Shizuo noticed, with a lurch in his stomach, that Alex had a sizeable bulge showing in his underwear. He looked only semi-hard, yet he was still almost twice Shizuo's length when fully hard. 'It's not fair,' thought Shizuo. 'How come he is so big? She must have noticed by now, right? How is she ok with this?'

Eun-ae gave him an innocent smile as she waved her hand. "Hey honey! We're just finishing this episode and then we can go, ok? I really love this show."

"Yeah, we both love this show," said Alex, flashing him a cocky grin as he pulled Shizuo's girlfriend closer to him, like he owned her. And worse, she didn't even protest, giggling as she nestled on his toned chest, her eyes back on the TV screen.

Shizuo frowned and gripped the door handle tighter. "What am I supposed to do then? Sit here and watch you two?" He asked, coming across as more annoyed than he first intended. He was never good at masking his irritation around Alex, even while his girlfriend refused to see reason.

Alex didn't mind Shizuo's tone. "Yeah, sit here. I'm sure this show would be your kind of thing too."

"But Eun-ae," replied Alex in a playful tone. "I was having such a good time, just like old times. You were so soft, too."

"Hey!" Shizuo interrupted.

But Eun-ae simply laughed. "Oh Alex, is always joking around. Don't mind him, Shizuo," she told her boyfriend. "He is my best friend after all," she said, giving him a light peck on the cheek. "You are a lot of fun, Alex, but Shizuo is my boyfriend." She turned to Shizuo then, giving him her most innocent expression. "Don't worry, honey, he is just flirting. You know he is gay."

"That's right" replied Alex, giving Shizuo a knowing smirk. "See? Nothing to worry about. Besides, even if I were straight, she is your girlfriend, I wouldn't do anything to her... Even if she is ridiculously hot. Am I right?"

"Uh-huh. Well, we're going now," replied Shizuo, not bothering to hide his skepticism. He felt his face getting red, his anger rising. He didn't want to cause a scene, but he wasn't about to stand there and let Alex flirt with his girlfriend like that!

"Wait, don't you want to finish this episode with us?" asked Eun-ae in a whiny voice. "It's a great show, and I am sure you'd love it too."

"I doubt that. Besides, you said you were going to be ready when I got here. Are you not ready?"

Eun-ae looked down, her expression sheepish. "Well, I got a bit carried away with the show. It is really interesting! You can sit down and watch with us, really, you'd like it."

"Yeah... You know how it is," shrugged Alex. "It's easy to get carried away when you're having fun." He gave a lewd grin as he said it, and Shizuo caught the double meaning immediately.

He gritted his teeth. "No, I'm not going to sit and watch some show with you and him. Come on, we are going." He looked at her with a stern expression, trying to get his point across.

Alex chuckled, then turned to Eun-ae and said in a mocking tone. "He sounds like a jealous boyfriend, Eun-ae. You should go with him. We can finish this episode later."

"Alex!" Eun-ae chided, turning to Shizuo. "Honey, you're not going to make a scene now, are you?"

"Me? I am not the one who is being indecent here," he replied, anger seeping into his voice.

"Oh please," replied Alex, standing up and stretching his arms, showing off his toned body. "We are not being indecent at all, it's nothing any of us hasn't seen before! You are just being too uptight."

"You don't even know what you are talking about," replied Shizuo in an annoyed tone.

"Really? It sure looks to me like you are the jealous type. And it is not fair, is it? I'm not doing anything wrong by being the way I am." He flexed his arm, making his biceps bulge. "Don't take it personally, friend. Wouldn't want to make you feel... Inadequate next to your girl." Alex sneers as he says inadequate and Shizuo swears he can see Alex's cock twitch inside his underwear, the fabric straining to contain the python between that asshole's legs.

"You know what," said Alex. "You seem really angry, I'm afraid you may have a heart attack or something. I'm only trying to make this more fun for your girlfriend, but you seem so upset that I think we should just drop it."

"I know you were just joking," said Shizuo sarcastically.

But Alex ignored his sarcasm and turned to Eun-ae instead. "Sorry for not being more considerate, Eun-ae."

"No, I'm sorry, Alex!" She replied, her face worried. She got up from the couch and gave him a tight hug, her small body completely enveloped by his muscular arms. Shizuo gritted his teeth as he watched that, his eyes going to Alex's underwear and the outline of that enormous cock. 'She must have noticed that already. She can't be blind,' he thought. 'I wonder if she secretly wants his cock inside her. No, don't think like that! She wouldn't do that. But still…' He couldn't stop his imagination from going there and he could feel his own erection growing as he watched his girlfriend hug the guy she always said was her best friend, and the same guy he always thought was a creep.

"No, you are so nice to me," said Eun-ae. "I love being here with you. It's always fun when we're together."

"I'm glad," replied Alex with a smile. "You know I love being with you too." He squeezed her small frame tighter and she giggled again. Shizuo could feel his anger and arousal growing in equal parts, and he didn't like it one bit.

"You always make me feel better," said Eun-ae as she squeezed him back. "You are such a great friend."

"Yeah," replied Alex. "The best, right?" And then he ran one hand down her back, until he could give her ass a squeeze and she jumped a little in surprise.

Shizuo opened his mouth to protest. "Hey! What the fuck do you think you're doing?!"

"Alex! That's not nice," replied Eun-ae with a pout as she moved his hand away from her ass.

"No, sorry, I was just joking. You always told me you wanted to do that too, right?"

"I did?" She looked at him in confusion, her innocent face a complete contrast to Alex's cocky expression.

"Or did I misunderstand? My mistake then," said Alex with a cocky smile. And then he did something that made Shizuo even more angry. He slipped one hand inside Eun-ae's shirt, his fingers disappearing under the fabric as his arm moved up and down in an obvious motion, groping her._ His face was stoic as he looked at Shizuo, but his eyes were laughing, mocking him as he groped his girlfriend'_s bare breasts and she moaned softly.

"Right, this is what you wanted, right?" He asked her. "You said you wanted me to feel them and tell you what I thought of them."

"Oh yes," replied Eun-ae after a moment, blushing. "I did say that, didn't I? You are so manly, Alex! I just wanted to see how it felt."

"Yeah. And? What do you think?"

"It’s… nice," she replied in a soft voice, blushing a little. "Your hands are so big and rough."

"And you have such nice tits too, Eun-ae!" He replied, his voice loud and booming. "Such nice, large, perky tits."

Eun-ae giggled and looked away. "You're embarrassing me," she said with a blush on her face.

"No, I am not," he replied. "I am just speaking the truth. Help me out here, Shizuo, I need a straight guy's opinion. She does have nice tits, right?"

"You're... You're not supposed to," stammered Shizuo.

"C'mon man, say it. Your girlfriend has nice tits."

"Yeah…"

"Well, that's good. You know what? I think you should feel them too. Maybe it will help you relax a little bit. Come on, feel them."

"What? No!" Shizuo said, taking a step back.

"Oh? Sorry, didn't mean to upset you honey!" Eun-ae said after a moment, her face flushed red with embarrassment... or was it lust? She pushed Alex's hand away from her breasts and reluctantly moved away. Alex let her go, his arms falling limp to the side.

"Oh, I'm sorry. I guess that was a bit much," he said, sounding unapologetic. He had a devil-may-care grin on his face, his expression mocking as he looked at his girlfriend and Shizuo.

"I am sorry, Shizuo," said Eun-ae with an innocent expression on her pretty face. "He was just joking, you know he likes to joke around like that. He wouldn't mean anything bad by it, you know?" She walked closer to Shizuo until she was standing right in front of him. "I'm sorry," she repeated.

"Yeah… It's fine."

"You know he is just my friend, right?" She asked, her voice pleading.

"Yeah, I know."

"Really, I am sorry. He was just being silly."

"Yeah."

"But he is my best friend! And he is gay, you know that!" She added in a louder voice, turning her head to Alex, who was still grinning at them.

"Yeah," said Alex. "I am. But you know, I really don't mind. If your boyfriend doesn't want to do it, I would gladly grope your tits instead."

"Hey! Why do you always have to say that?" Shizuo replied, raising his voice. He clenched his fists, trying to control his temper. He felt like punching Alex in the face, but he didn't want to cause a big scene in front of his girlfriend. "Can't you just stop with all that perverted stuff?"

Alex looked at Eun-ae, then back at Shizuo, his grin briefly vanishing. "Seriously man. You have to take good care of your girlfriend, give her lots of attention.. If you don't? Another guy might satisfy her instead of you." And to Shizuo's horror Alex idly began rubbing one finger against the head of his cock, over his underwear. He did it in view of everyone, even as he wrapped his other arm around Eun-ae. Shizuo saw his cock visibly throb and grow even larger, now slightly lifting the waistband as his underwear struggled to contain his cock. It was definitely twice as large as Shizuo's, at least. Probably more. And thicker too. But Eun-ae didn't seem to notice, only looking at Shizuo with her wide, innocent eyes. "You have to up your game if you want to compete, buddy." Alex grinned.

"I am not competing against anyone," said Shizuo. He turned to look at Eun-ae. "Come on, let's go. Now."

"Yeah, I'm so sorry, Shizuo!" She replied. "I think that would be for the best. I need to get dressed anyway."

"No!" He said quickly. "Don't bother. Let's just go."

"What?"

"You heard me."

"But I can't go outside like this!"

"Well, you can wear a jacket or something. Just go outside, and we can wait for a taxi or something."

"That sounds embarrassing. People will think we did something."

"Well, we didn't! And I'm not waiting here. I am leaving, and I am taking you with me. I'm going to your house."

"No!" She replied with a look of distress. "I… I will get dressed. Just give me a few minutes, OK?"

"But…."

"Shizuo!" She pleaded with him.

"We're leaving. Now."

"I'll wait outside," he said after a moment. He looked at Alex. "Make sure he doesn't come with us."

"What do you think I am, a babysitter?" Alex asked.

"Stop it, you two," said Eun-ae.

"We are going home, I told you."

"No, you are waiting outside."

"Huh?"

"Get out," said Eun-ae, pointing to the door. "Go. I'll get dressed and we can go."

"But I am not leaving you with him," he complained.

"I told you," said Alex. "We are just friends. Besides, it's my place."

"We're leaving, I told you! She will leave too," insisted Shizuo.

"Yeah, but she is not dressed," said Alex. "Let her get dressed. If you're so mad you can just wait outside."

"See? He has a point," said Eun-ae in an excited voice. "You should wait outside, Shizuo. I'll be out in a moment."

"But… Fine," said Shizuo bitterly.

"Good. We'll see you soon," said Alex.

"Yeah," replied Eun-ae. She hugged him and kissed his cheek. "Thank you, honey. I'll see you soon, OK?"

* * *

Eun-ae closed the door after Shizuo left and immediately turned around. She looked at Alex and smiled. "Thank you so much."

"No problem," he said, a big grin on his face.

"I really appreciate it."

"Yeah. Sure you do. Your boyfriend seems to get really riled up by it though. Is it worth it? Are you sure he won't just break up with you?"

"Of course not!" Eun-ae replied with a confident tone. "And that's what I want! He gets so jealous and worked up, and then we have amazing sex."

"Wait, wait, wait," replied Alex. "I know that. That's the only reason I agreed to help you, you know. I get why you would want to play around. But are you sure it's safe? I mean, you are making him pretty jealous of me. If he tried to fight me there's no way any of us is coming out looking good, right?" Alex smirked.

"You're not that funny," replied Eun-ae bitterly.

"Yeah, right. Anyway, I'm serious. Are you sure it's worth it?"

"Yes. Yes, I am."

Alex raised one eyebrow.

"What?" She asked.

"No, nothing. But I would hate to be the reason you get dumped. I mean, I want you to be happy, I just worry that playing with fire is dangerous."

Eun-ae scoffed. "Oh please. I'm not cheating on my boyfriend. We have been together for three years and he has never been happier. Or me either."

"Yeah, but… Why don't you just tell him what you want?"

She sighed. "He's just too nice. Too considerate. I like it, but sometimes he's just too gentle. He never wants to do fuck me as hard as I want... Unless I encourage him a little."

"That's pretty devious." Alex chuckled softly, but his expression was affectionate, friendly. "He must really like you to deal with your bullshit and not break up."

"You went along with it, don't act all innocent on me" she replied, smiling as she pulled her skirt up.

"... Fair enough," replied Alex. "Besides,he's a nice guy. I don't know him very well, but he seems nice.

"Oh yeah!" She said, smiling brightly. "He's amazing in almost every other area. So getting him riled up now and then? It's all worth it!" She looked at Alex and smiled a little. "But you're really cool yourself. And a great friend. Just... Too bad you're gay."

"I'll take it as a compliment," Alex replied stoically while pulling up his pants. Eun-ae bit her lip, her eyes shining with curiosity. "Hey. Can I see it again? Just for a moment."

"Uh…"

"Pretty please?" She pleaded in a sweet voice.

"… Yeah. Sure." And he pulled down his underwear again, letting his cock swing free. It dangled, still large and menacing, but before her eyes it was already shrinking and growing flacid. It was still impressive, of course, but...

"Going soft already?"

"Yeah. It's not like I can hold it forever," he shrugged, smiling. "And sorry but you don't do it for me, no matter how pretty you are."

"What a shame," she chuckled and gave him a lewd grin. "If you weren't gay... I bet you could make a lot of women very happy. Or at least break a few bitches in bed."

"You think?"

"Yes, I do," she said, smiling at him. "You're gay though, so I guess you'll be making a cute guy your bitch instead, huh?" She sighed.

"Yeah, well… Maybe not so much. It's so hard to find a guy that wants to bottom for me." He clicked his tongue, annoyed. "Doesn't help that I broke up with my boyfriend."

"Oh, I'm sorry to hear that…" She said, and meant it. "Was it a messy break-up? Or am I being nosy?"

"Not too nosy, don't worry," he said with a sad smile. "It wasn't messy, really. But… We're not seeing each other any longer. That's about it." He shrugged, his smile becoming bitter. "Now I am all alone again and it's back to trying to make friends all over again."

"I know that feeling. It sucks."

"Yeah." He sighed, his shoulders slumping. "That's life. You got your boyfriend though. At least you're doing well, so that's a plus."

"Yeah. It is," she smiled, finishing putting on her skirt. "I better go, he is going to get impatient." And she walked past him towards the door. "Thanks again. I owe you one."

_"Yeah. No problem," he replied, a small smile on his face a_s waved at her. "Have fun."

"Bye!" And she opened the door.

"Bye."

And he watched as she left the room. Once she was gone and the door closed, the smile vanished from his face. He looked tired now. He walked over to his desk and sat down in front of his phone. He sighed, staring at it. He hesitated for a moment and then dialed a number and lifted the phone to his ear. He waited, his eyes on the ground. "Hello? You are not answering?… Fuck," he cursed and hung up. He looked dejected, and he sighed once more before putting the phone down. He looked at the closed door for a long time, then finally stood up and walked away, feeling like an idiot. And he went to his bed, pulled his pants down and laid down on his side. He started playing with his cock idly, absentmindedly rubbing its head and shaft. He closed his eyes and sighed, feeling himself getting hard again. "Fuck," he murmured. "Shit." And then he sighed again and began stroking his cock. He would have to find another boyfriend soon, he thought. Maybe a freaky and eager twink, ready to worship his thick rod with stars in his eyes and an easy smile on his lips, as he wrapped them around his head...

Alone in his room, Alex fantasized of a hot guy sucking him off, as his breathing grew ragged.

* * *

Back at Eun-ae's house, Shizuo was pushing her against the bed. She was dressed now, but Shizuo was pulling at her skirt and shirt, his hands eagerly feeling her up. She gasped, biting her lips as his hands went to her breasts. "Mmm! Oh, Shizuo…"

"Shh…"

He pulled her bra down and her breasts spilled out. Her nipples were hard and Shizuo lowered his head to kiss and nibble on them, and she moaned in response. She spread her legs and let him grind his cock against her crotch as he groped and kissed her breasts. She bit her lip and moaned, feeling him getting hard against her. His hands went down and lifted up her skirt and then she was pulling her own panties down and they rolled down the bed to the floor, and now she was only dressed in her shirt, bra pulled down and her skirt rolled up to her hips. She laid down on the bed and spread her legs, and Shizuo pulled his pants and underwear down and his cock sprang up. She stared at his hard cock for a moment, her mouth dry and her heart pounding in her chest. It was painfully hard, and while not as big as Alex's she still eagerly admired as it drooled precum on her pussy. "Fuck me," she pleaded. "Please…"

"Yeah. Yeah, I will," he groaned and pushed into her. She felt his cock stretching her pussy and she moaned loudly, wrapping her legs around his waist. She bit her lips and moaned as he started fucking her, hard and fast. He was fucking her with an animalistic, frenzied passion. His hips moved fast and hard, pushing his cock into her in a frenzy of lust and jealousy. He grabbed her breasts and squeezed them, moaning loudly as he fucked her hard. He was rougher than usual and it was exactly what she wanted. She wanted him to fuck her like an animal, she wanted him to fuck Alex out of her system.

"Ah! Ah! Yes! Yes, please!"

He fucked her in missionary, her legs wrapped around his waist and he kissed her as he rammed his cock into her, again and again. She moaned into his mouth and kissed him back, feeling her pleasure build up with every hard thrust. "Yes, yes! That's it, baby!" She moaned.

Eun-ae came, moaning loudly as she wrapped her legs around Shizuo's waist and pulled him into a kiss as she orgasmed. Her pussy clenched around his cock and he moaned into her mouth, fucking her faster. He fucked her through her orgasm and then he pulled out and came on her breasts, groaning loudly. They were both covered in sweat and panting loudly. She looked at him and smiled. "Good," she said. "Very good."

"Yeah," he said. "Tell me how good it was. Tell me again" He whispered, looking down at her while breathing hard. Pleading with his eyes.

Eun-ae giggled, her face flushed, before she ran her fingers over her breasts, smearing his cum and her sweat all over them. "You were amazing," she whispered.

Shizuo couldn't help but smile. "Thanks." He hesitated, but it wasn't worth it spoiling this good moment. "You're amazing too."

"Aww, I love you!" She pulled him closer and gave him a passionate kiss on his lips, which he eagerly returned.

"Yeah. I love you too," he replied in a tired voice. He pet her hair and laid down beside her, closing his eyes.

* * *

_In his dorm, Alex groaned softly. He was stroking himself, his eyes closed. He bit his lip and moaned softly, his legs spread wide open and his hand working his cock up and down. He was rubbing the tip of his cock, his thumb rubbing the precum around. He bit his lips and groaned, his heart pounding, his breath ragged. He moaned and sighed, stroking himself until his body went tense and he came. He grunted and came on his hand and stomach. He sighed and shivered, then slowly opened his eyes. He laid on his bed for a while longer, then he cleaned himself up and got dressed again. Then he laid back down on the bed, and rolled around until he was comfortable. He stared at the ceiling for a moment, then turned off the lights. He was alone in bed again. He sighed. "Maybe next time I'll find someone who can appreciate this," he murmured in the dark as he closed his eyes and tried to fall asleep. _But sleep, stubbornly, refused to arrive, forcing Alex to notice the silence in his dorm as he lay in bed.

He shivered and hugged a pillow for comfort.
