Waking up startled when seeing a colleague "riding a horse" with me

When he woke up, Ono was surprised to find himself in a hotel room, feeling dizzy. Looking to the side, he saw a naked girl lying next to him!!! The girl was Sakura from the company's reception desk. He remembered attending a welcome party for the new company employee, who happened to be him. Being offered drinks from one glass to another, he quickly got extremely drunk and passed out, not knowing anything else. Waking up, this is what he found. "No way!". That was Ono's thought at the time, because he had a girlfriend and couldn't do this with such a beautiful girl.

To prove themselves, they had sex, and Sakura showed Ono his filled pussy with his sperm. It was late, impossible to go back, and Sakura kept seducing him, making him have sex with her throughout the night. Sakura continuously drained Ono's sperm, he could hardly even close his eyes. The result was that the next morning, he couldn't go to work. Later, hearing from colleagues, Sakura always participated in welcoming parties for new employees, she always helped that employee get home, and it was almost certain that the next day he wouldn't be able to go to work...
