Daiki Tachibana, from Class 2-D, was a member of the track and field club and also Yui Obata's boyfriend.
They hadn't been dating for long. He had only successfully confessed and started dating her recently. Yui Obata was a member of the girls' basketball team. Daiki Tachibana had seen the girl's cool demeanor several times and gradually fell for her.
That's why he took the initiative to confess.
He was thrilled for a long time after the successful confession. However, Yui Obata seemed very busy lately, and they hadn't seen each other much. He didn't know that Yui Obata wasn't just busy; she had been targeted by another dangerous individual.
Of course, he realized it now.
He had just witnessed the scene with his own eyes. His girlfriend, the girl he loved, had leaned in and kissed him? And it was a kiss on the lips… Honestly, seeing that, Daiki Tachibana felt his veins almost explode.
Yui, what are you doing?!!!
And now they are still hugging, not letting go! You two, let go of each other!!!
Daiki Tachibana roared frantically in his mind.
"Yui! Who is he?! What is your relationship?! What exactly is your relationship?!" Daiki Tachibana's shouts were hoarse and edged with desperation, his eyes bloodshot.
"Daiki, what's wrong with you?" Yui Obata, under Hypnosis, didn't understand her boyfriend's excitement. She frowned, turning to look at the boy beside her, her expression conflicted. "Alex and I…"
What was her relationship with Alex?
Yui found she couldn't answer. It seems like I don't have any specific relationship with him… Even Mom was his Mistress, having a master-servant relationship with him. What about me? It seems like I'm nothing.
"Alex and I are just ordinary friends."
After saying that, a wave of resignation washed over Yui Obata. The girl felt empty and disappointed.
"Ordinary friends?" Daiki Tachibana was not calmed down. He was even more agitated than before. "Ordinary friends, why, why, why would you… Kiss him?!"
"Eh?"
"I saw it all!!" Daiki Tachibana gasped for breath. A Kiss! Even I, your Boyfriend, haven't done that!!
"Is there anything strange about that?" Yui Obata didn't understand why her boyfriend was so worked up. "The kiss was just a greeting between friends. Isn't that normal?"
Normal…
Daiki Tachibana was dumbfounded. He never expected his girlfriend to say something so bizarre.
What is going on? How could she say something so strange?
"Ahem," Alex coughed, having to interrupt the two. "Um, you're Yui-senpai's Boyfriend, right? Please don't misunderstand. Yui-senpai and I are truly just ordinary friends."
"As for that kiss just now," Alex kindly explained, "Normally, friends shouldn't do that—"
"Alex…"
Glancing at the nervous girl beside him, Alex suddenly smirked, changing the subject. "But, Yui-senpai is different. Yui-senpai is a Nymphomaniac, after all~"
"Alex," Yui Obata glared at him playfully, sounding a little hurt. "Where am I a Nymphomaniac? To say that about me… Calling me a Nymphomaniac is so mean!"
"Isn't it?" Alex put his arm around her slender waist. His hand smoothly glided along the girl's curves, reaching her ample Breasts right in front of Daiki Tachibana, gently kneading them.
"Ugh~ Alex, don't…"
The girl shuddered, trying to break free from Alex's advances, but her body was soft and utterly incapable of refusing him. She could only lean on his shoulder, panting with her lips parted, the blush spreading from her face to her ears, enduring the boy's transgression.
"Yui!!!" Daiki Tachibana roared in front of them, his eyes bloodshot, watching the scene.
"Don't you want it? Yui-senpai, your body is already feeling it, isn't it?"
"Ugh…"
"Still claiming you aren't a Nymphomaniac? You get like this from just a little touch. I bet you're already very wet under your skirt, aren't you?"
Yui Obata clamped her legs shut, glaring at the boy in shame and anger. Her large eyes were watery. "It's all Alex's fault. I only get this way because it's Alex…"
"You bastard! Let go of Yui!!!"
Daiki Tachibana watched with bulging eyes. He finally lost control and charged forward. Alex, still holding the beautiful girl with one arm, delivered a light kick. The Cuckolded Boyfriend's eyes bulged, and he collapsed to his knees, clutching his stomach.
"Yui, I didn't want to use force, but your Boyfriend is too agitated. Are you going to be mad at me?" Alex blinked innocently.
"I know. I'm not mad at Alex," The red-haired girl looked at her Boyfriend on the ground and pursed her lips. "Daiki, why did you hurt Alex? He's my good friend. How could you do that?"
I'm clearly the one being hurt!
"Yui…"
Daiki Tachibana looked at the girl he loved with disbelief.
Alex felt Yui Obata was Playing the Innocent Card, though he was the cause. "Yui-senpai is right, Senpai. You shouldn't be so emotional. Even though Yui-senpai and I have Kissed and touched, she is still your girlfriend, isn't she? It doesn't affect anything."
"By the way," Alex suddenly lowered his voice, "I spent the night at Senpai's house last night. Senpai, your girlfriend… is very wet and makes me very comfortable."
"Y-You're lying! Yui, he, he's lying, right?!" Daiki Tachibana couldn't believe it.
"Daiki, what Alex said is true…" Yui Obata's cheeks flushed. She touched her abdomen. "This time is my fertile period, and that bad boy even Finished everything inside me…"
"!!!"
Daiki Tachibana broke down!
What? What did she say? Finished inside her… Yui, what have you done? What are you doing?! Why, why would you do this?!
More than the physical pain, Daiki Tachibana was overwhelmed by the psychological blow. His pupils constricted. He looked at his girlfriend, pale, watching her cover her abdomen in shame, leaning in that person's arms, having her Breasts fondled.
His body trembled.
He was on the verge of going completely mad!
His own girlfriend, she was… with someone else…
"Tsk, Yui-senpai, is it okay to say such mean things to your Boyfriend?" Alex asked, glancing at her.
"It's fine. Daiki is just a Boyfriend. We have no other relationship, and I haven't let him touch me."
"Tsk tsk, you say that as if you don't even like him… That's cruel."
"I…"
Yui Obata opened her mouth, suddenly speechless. The truth was, she didn't have strong feelings for Daiki Tachibana anymore. They hadn't been dating for long. Although she had accepted his confession recently.
Her feelings weren't deep.
Compared to Daiki Tachibana, she was far more preoccupied with Alex after spending the last few days with him…
But if I say that, will Alex think I'm a bad girl? As Yui Obata hesitated, Alex's hand on her Breast suddenly tightened. He hugged her close, smiling wickedly. "But I'm very happy."
"Eh?"
"You are mine now. No Boyfriend or anyone else is allowed to touch you," Alex curved his lips. "So, I'm quite pleased."
"Alex, you're so dominant," Yui Obata said softly, but her eyes shone. "I… Am I Alex's person now? Just like Mom?"
"Just like her."
Her heart pounded. The girl's heart melted. She said happily, "Alex… Can you come back to my house tonight?"
"Not tonight. I have to go spend time with the other girls."
"Woo, I'm jealous~"
Watching the two flirtatiously walk away, seemingly forgetting all about him, the abandoned Boyfriend lay on the ground, heartbroken. "Yui? Why, Yui…"
