Why this happens ?

[rickishi]

I have a hot co-worker at work place ,she is half an inch taller than me and bigger too and so for obvious reasons I am into her

Usually I flirt with her by touching or playing with her hair while she is seated ,but today I started ransacking her workplace for fun when she was not in her place. when she saw that from a distance she came menacingly towards me, she came very close towering on me (she was on heels) and forcefully held my palms tightly and with a dominating tone asked me "how dare you ? "

friends at that moment I went weak on my knees and I guess my facial expresion changed too ,I was really dumbfoundedand my heartbeat went fast. Does this happen with all ?
