Poseidon had no idea why he stood still, why he let the girl get the upper hand on him. In thousands of years, he had only let a few women ride him and he was usually fucking them. He snorted and pawed the ground, trying to shake her off although he was trying halfheartedly. She smelled wonderful and the way she was holding onto him was an incredible turn on for the ancient god. She is my employee, don't even think about it. Jeremiah was grumpy that they had been caught. Didn't want to be in the situation with a potentially damaging situation. He cursed Poseidon and mentally kicked him. Stupid gods and their stupid desires.
Poseidon was grinning madly. He had a woman on his back and a growling mortal in his head. It was amusing. Make me. He said quite clearly to Jeremiah and to the girl as well even though she couldn't understand it.
He took off at a dead run, ignoring her grip and her nudges. The stallion had it's limitations and she could force him to slow down if she tried but he knew that he was going to make her work for it.
