My cute childhood friend... One day, she was destined to be my bride. At least, that's what I thought. However, I wasn't able to be forthright with her. I had to put on airs... And because of my stupidity, she ended up getting stolen away by my disgusting friend... Now that I've lost, what can I do? Simply watch, and jerk off as I imagine what could have been...
