Her eyes widen in surprise as she watches her boyfriend approach, his expression dark with anger and jealousy. She can't help but feel a thrill of arousal course through her at the sight of them together like this, their bodies pressed so close. As he pushes his hardness inside her, she moans softly, arching her back to meet his thrusts.

Her hands grip your shoulders tightly, feeling the heat and strength emanating from you as you continue to thrust into her ass.

Her breath comes in short gasps as she feels the pleasure from all three cocks inside her, filling her up so completely. Her body shudders with each thrust, her moans mixing with those of her boyfriend and the stranger who had dared to touch what was once hers alone. The sensation is overwhelming, but in a way that leaves her aching for more.

Her eyes close tightly, trying to focus on the sensations coursing through her body as she moves her hips against each of them in turn.

She extends her arm, offering the stick to you. "Will you..." she whispers, her voice cracking. "Will you look at it for me?" Her hand is shaking so badly that you're not sure if it would even register as positive or negative.

Do you take the test from her and check the results?

You carefully remove the pregnancy test from her shaking hand and inspect it, trying not to let your own emotions cloud your judgment. After a few tense moments, you look up at her with what you hope is a reassuring smile. "It's positive," you tell her gently.

Her eyes widen in shock before they begin to water. Tears stream down her cheeks as she throws herself into your arms, sobbing with relief and joy. "I can't believe it!" she cries, hugging you tightly.

"Oh, god!" The gyaru cries out in ecstasy, her body tensing and shuddering beneath you as she comes undone around your cock. You feel her walls contract rhythmically as she rides out her orgasm, moaning and whimpering with each thrust from both of you.

As the old man nears his own climax, he growls, "You're a dirty little slut!"

The gyaru laughs breathlessly, her face flushed with pleasure and shame. She glances over at her boyfriend once more, still too far away to notice what she's doing. "Yes," she pants, "I am." Her body trembles as the old man finally reaches his peak, filling her ass with hot cum.

With a satisfied groan, he pulls out of her and turns back around in his seat, leaving you to enjoy your victory lap inside the gyaru.

As she walks away, she can't help but steal glances back at you over her shoulder. There's a mix of guilt, desire, and longing in her eyes, a silent plea for you to understand the turmoil she felt in that moment. She knows what she did was wrong, cheating on her boyfriend like that, but the intensity of her attraction to you overwhelmed her rational thoughts.

Once she reaches her boyfriend, she slips back into her role as his devoted girlfriend, smiling brightly and leaning into him affectionately.

"Hey, babe!" she coos, nuzzling his ear with hers. "I'm so sorry about getting separated from you earlier. Are you okay?" she asks innocently, still trying to process what just happened between her and the stranger on the train

Her boyfriend looks at her confusedly, unaware of the seductive encounter she just had. "Ah, yeah, I'm fine. Just got jostled around by the crowd," he replies, smiling reassuringly.

She nods, relief washing over her face once more. "Oh, good.
