As this is the second part, I recommend you to read the first part then come back here to give more context to the story.
Ana almost finishes her contract. Before her last day, her boss asks her to have a meeting with the purpose of extending the contract. The boss can't deny that Ana is the one who makes her club packed every night. However, for Ana, it's a definite decision to finish her contract and then stop. It's too much for Ana, who was a quite conservative and innocent girl right before she worked at that club, to now become a girl who must expose her body almost naked and be caressed and groped in just a month. The boss even promised her that her uniform would be ready during the new contract duration, but Ana's decision is final. They both then agree, but before the contract finishes, the boss orders Ana to wear the g-string on her final day. As usual, Ana can do nothing but obey her boss. Besides, she has done that once when the picture of the club's ads on the big screen in front of the club was taken. It's just the final one for her.
The final day has come. Ana arrives at the club to change her usual uniform: the red very short dress, 2 cm from her crotch, tight on her stomach, strapless loose on the top, and only a g-string behind the dress, where the string is hidden in her ass crack and the bottom of her ass is shown even when she's standing. She found the stage in front of the club, which has now been changed to a mechanical bull arena. A thick padding floor with a mechanical bull at the center of it.
The boss knows that Ana is the main reason for her successful business because of Ana's exposure. With that reason, the boss thinks, What if it's not just her employees but the customers themselves that could give a "show".
On that day, the club is holding a challenge: anyone who can stay on top of the bull for 10 minutes will get free-flow beers for a week.
It was Sunday night, and people were coming early. At 7 p.m., the club is almost full. Ana is already busy delivering drinks here and there, where she faces the usual situation of flirting, caressing, and being exposed.
At 9 p.m., the mechanical bull "show" is starting.
Many people are signing up--all boys, of course--to get free drinks. After about an hour, no one can beat the bull. All the guys were getting bounced around and then thrown from the bull to the very thickly padded floor.
Then there is the first girl to come to the stage. She has very big boobs and is wearing short jeans and a white shirt. The operator swung the bull quickly back and forth and up and down to make her huge breasts swing wildly inside her shirt for the guy's enjoyment. Whenever she tried to hold her breasts with her arm, the operator would buck the bull enough that she'd have to grab for the strap and again free her breasts. She can just stay there for 5 minutes before being thrown by the bull.
Since then, more girls have signed up for the challenge, mostly quite drunk and being challenged by their group. More people are coming and surrounding the bull arena.
The next girl with a low-cut top bounces up and down quickly enough that one breast pops completely out of the top to the cheers of the crowds.
Another girl wearing a tight-fitting dress is up. The assistant helped her up onto the bull. She carefully tucked her skirt under her in the back and between her legs and securely held onto the strap before the operator started gently rolling the bull around. Suddenly, the bull lurched repeatedly forward and back, which caused her dress to creep out from under her. The bull then pitched slowly forward and back, but just fast enough to raise her ass off of the bull and cause her skirt to ride up. Each time she pitched forward, she lifted up to expose her very brief panties and well-formed cheeks from the back. She vainly tried to keep pulling her dress down as it inched toward her waist, but couldn't because the operator would give her an extra lurch sideways, which made her keep grabbing for the strap.
He pitched the bull's head toward the floor and the tail up, which threw her forward, lying on the bull's head. As he swung the bull quickly around, the force held her in this position with her skirt up to her waist, her butt raised, and panties completely exposed. As she turned, unable to sit back up, all the guys cheered loudly and got a good view. She finally slipped off and fell to the deeply padded floor with her legs spread and her skirt at her waist, giving everyone a final good show as she struggled to get up.
The bull's operator was very adept at making the bull move more gently for the girls to stay on the bull longer and was talented enough to display their attributes. No girls leave the bull without any exposure. He can move the bull in the right ways to intentionally jiggle or expose their breasts and raise any skirts. All the boys will be violently thrown out very quickly for not spending too much time with boys.
