One day, I accidentally caught a glimpse of my crush, Ms. Hongou, having sex on the stairs. Since then, my days have been filled with her teasing me with glimpses of her panties, breasts, and sex. She seems to enjoy seeing me aroused, but for some reason, she always leaves me hanging. Even though it's frustrating to see the girl I like being taken by another man right before my eyes, I can't stop myself from being aroused today either.
