MIAE-243 Mari Takasugi got an erection when she saw her childhood friend who was helping me being raped by a bully.

My childhood friend Mari has always come to my rescue whenever I've been bullied. - Even after graduating, that hasn't changed and he still came to help me! - But when she gets revenge, she becomes lewd. - Now it's my turn to muster up the courage and help! - Oh...I have an erection. - Even though my precious benefactor is being raped... - I want to see more... - Cry more... - Ah...that's great... - I can't believe I get to see my favorite Mari like this... - It's frustrating that I feel great right now... - Benefactor NTR! - Scum erection!
