We're going on a graduation trip with a close-knit group of three guys and girls. I had finally decided to confess my feelings to Riho, and I thought my friend was supporting me too... But as I hesitated, I heard sweet moans and sounds from another room. Could it be...? There was Riho, giving in to a night of passion and even letting my friend cum inside her. "Why did she choose him over me?" If only I had confessed back then! Even as I felt a mix of frustration and resentment, Riho and my friend were passionately making out. She didn't even care if I saw them, moaning loudly as she indulged in the intense sex. I should have never fallen for her.
