I wanted a boss like this! After a drinking party, I missed the last train and stayed over at the home of my section chief Lan Hua(who works at a gal apparel company), and she kept teasing me like a slut! Lan Hua was drunk and horny, so I had sex with her at her command, but she was so much more slutty and sexy than I'd imagined, that I ejaculated instantly. When she found out I was a premature ejaculator, she played with me even more and tested how many times I could ejaculate! Her black ass' cowgirl position and sex techniques were so nasty that I unexpectedly woke up with a virility! Even after I ejaculated, I got a second erection and continued to cum from Friday night until before I went to work on Monday!
