Marin Kitagawa stood outside Alex’s apartment, her fist hovering over the door as she hesitated. Anger coursed through her veins as she thought about how Alex had been tormenting her friend Gojo Wakana. He doesn’t deserve this, she thought, clenching her teeth. I’ll make him stop, no matter what it takes. Taking a deep breath, she knocked firmly, her determination outweighing her nervousness.

The door opened, and there stood Alex, a towering figure with an air of confidence. He leaned casually against the doorway, a smirk playing on his lips as he looked her over. “Marin Kitagawa,” he said smoothly. “What brings you to my place? Didn’t think we were on speaking terms.”

Marin stepped inside without waiting for an invitation, glaring at him. “You need to stop picking on Gojo!” she snapped. “What’s your problem with him?!”

Alex chuckled, crossing his arms. “Problem? No problem. I just like messing with him. The guy’s so easy to rile up.” His tone was calm, but there was a hint of amusement that only fueled Marin’s frustration.

“Well, it’s not fun for him!” she shot back. “You’re going to leave him alone, got it? Or else!”

Alex raised an eyebrow, clearly entertained by her outburst. “Or else what, princess? You think you can stop me?”

Before she could respond, Alex closed the distance between them, his large hand suddenly cupping her chest. Marin gasped, her face flushing as she instinctively stepped back. “W-what are you—?!” she stammered.

“Relax,” Alex said, his smirk growing. “I’ll tell you what. You give me your body, and I’ll leave your little boyfriend alone. Sound fair?”

Marin froze, her mind racing. She glared at him, her fists clenched at her sides. “If… If I do this, you’ll really leave Gojo alone? For good?”

“Of course,” Alex replied smoothly. “I always keep my promises.” His hand lingered, and Marin shivered, her anger and embarrassment warring within her. “Y-you better not be lying to me, you jerk!” she snapped, her voice trembling.

Alex chuckled. “Enough talking, blondie. Stick out your tongue.” His voice was low and commanding, and though Marin hesitated, she eventually parted her lips, her tongue trembling as she followed his demand.

Before she knew it, she was sitting on his lap, her lips locked with his in a deep, heated kiss. Her hands clutched his shirt tightly as her mind spiraled. I can’t believe I’m doing this… she thought, her cheeks burning. This is so humiliating…

But as the kiss deepened, she felt her body respond in ways she hadn’t expected. One of her eyes fluttered open, and her thoughts grew more conflicted. W-why… Why does this feel good? This isn’t supposed to feel good!

Alex pulled back slightly, his breath warm against her lips as he smirked. “You were into that, weren’t you?” he teased, watching as she wiped her mouth furiously. “Ugh! No way!” she snapped, her voice cracking. “That was disgusting!”

Alex leaned back, his grin widening. “We’re not done yet, blondie. Come here and show me how serious you are.”

Marin’s hands trembled as she stood before Alex, her eyes widening when he revealed himself. Her cheeks burned as she stared, frozen in shock. W-woah… It’s huge! she thought, her breath catching. I didn’t think… Guys could even be this big!

Alex tilted her chin up, his voice firm but teasing. “If you want me to finish, you’ll need to take it deeper. Don’t hold back, blondie.” Marin gulped, nodding reluctantly as her hands hesitated before following his instructions.

Her voice was muffled and shaky as she tried to speak, her words coming out in broken, nervous mumbles. “W-wike dis…? I-I can’t…” she stammered. Alex chuckled softly. “Yeah, just like that. Keep going.”

As things intensified, Alex’s voice grew rougher. “I’m close… Swallow it all,” he commanded, his grip steady. Marin’s body trembled as she complied, her lips parting as she felt herself overwhelmed. A shaky “aah” escaped her lips as she swallowed, her throat visibly moving.

Later, Marin stood awkwardly, her arms crossed over her chest as she glared at Alex. “If you don’t keep your promise, you’re done for,” she warned, her voice laced with frustration. Alex simply chuckled, waving her off. “Yeah, yeah. Now quit yapping and get on the bed.”

She lay down nervously, her voice soft as she asked, “L-like this?” Alex smirked, his tone teasing. “If you’re not going to be sincere, blondie, you can forget the deal.”

Blushing furiously, Marin spread herself, her voice trembling. “P-please… Use my holes… and leave Gojo alone…” Alex leaned closer, his grin widening. “Good girl. That’s more like it. The more submissive you are, the better this will be.”

As the night continued, Marin found herself overwhelmed by sensations she never thought she’d feel. Her body trembled under Alex’s touch, her voice breaking as she cried out, “I-I’m cummmmiiinnggg!” Alex’s voice was firm yet teasing as he replied, “Stick out your tongue for me.”

By the time they were finished, Marin lay back, her chest heaving as her thoughts raced. Woah… He really pumped me full… she thought, her hand brushing against her forehead. But Alex leaned closer, his grin never faltering. “We’re not done yet,” he said, his tone playful.

“W-wait… I need a break…!” Marin stammered, her voice shaky. “I’m still so sensitive…” But as Alex pulled her closer, her thoughts betrayed her. I might… I might actually get addicted to this…

Few days later, Marin sat across from Gojo in the university classroom. “Marin, did you tell Alex to stop bothering me?” Gojo asked, his voice hesitant. “He hasn’t done anything to me lately.”

Marin’s cheeks flushed as she fumbled for an answer. “Oh, umm! Y-yeah, don’t worry about it!” she replied, her voice rising slightly. Standing up, she leaned forward with a mischievous smile. “I took care of him. He won’t bother you anymore.”

Gojo blinked, confused. “B-but how did you…?”

Turning her back to him, Marin walked to the window, where the breeze lifted her skirt slightly, revealing a small tattoo on her thigh. “I said, don’t worry about it, Gojo,” she said with a sly smile, leaving him speechless.
