My childhood friend Mari, who always stood up for me when I was bullied. Even after graduation, she remained the same, coming to my rescue once again. But this time, the situation is reversed—she's the one suffering, exposed in a lewd and helpless state. Now it's my turn to find courage and save her. Yet, inexplicably, my body reacts. Even though my beloved savior is being violated... I want to see more. I want to hear her cry out in pain. Ah... To finally see the Mari I've always loved like this... This moment feels unbearably euphoric. NTR of my benefactor! My cock betrays me!
