Queen x a1 checkmate

The black queen's eyes widened, watching the white rook approaching her claimed territory.
"They can't be so foolish", she whispered. Apprently they could.

Standing right before her, the 3 male warriors, guardians of the rook, aimed their spears directly on the majestic queen, threatening her life.
"Surrender now, or you will regret it!", the most cheekily of them shouted out.
"Show us your boobies!", another one exclaimed.

The queen burst out into laughter. "You stupid morons!" she said full of contempt. "How dare you to insult ME, THE MAJESTY!"
The queen looked left and right, checking one more time that there was no other piece on the board near enough to help the rook. Confidently she waited for the order she knew was about to come:

"Dear Queen, please go to a1 and destroy that rook!", the soft voice of the goddess above the battlefield sounded.

After finally getting her approval, the black queen stepped foreward. She closed her eyes, concentrating and gathering the magical power she was able to release in special situations.
Then, in a flowing movement, she touched the walls of the rook with her fingertips.

At first, nothing happened. After a few seconds, a tiny crack appeared on the wall starting from the queen's touchpoint. The small crack branched out into a spider's web that quickly encompassed the entire wall. Then, the cracks began to widen and the rook started to tremble.
The guardians screamed in panic, trying to escape from their fortress, which was now threatening to become their grave, but it was too late. With a deep rumble the tower collapsed, burying its guardians between the stones.

Nothing happened for seconds. The black queen was already about to turn away in victory and take the place of the destroyed tower, when the stones finally moved and three battered figures crawled out of the rubble.

But all will to fight has left the men, who were so cheeky a short while ago. Instead, they looked up to the queen with eyes widened in horror, an aura of invincibility surrounding her.

The leader of the guards finally found his voice again first. Submissively, he threw himself on his knees before the queen.

"Your Majesty, we implore you. We were fools and thought we were a match for you - what a terrible mistake. Please forgive us and spare our forfeit lives. We will do whatever you command us!"

The other two tower guards immediately followed their leader's example and threw themselves into the dust before the queen.

An evil smile stole onto the lips of the black lady. She nodded her head in homage. "So be it. I can very much use your service for my next performance!"

A little later, a disturbing picture presented itself to the present spectators. All three men were naked. Two guards knelt side by side on the field. Around each of their hips a rope was bound, which was connected in the middle and held the two together at a small distance.

The two ends of the rope disappeared between the legs of the men to tie off their genitals including testicles. The penises stood out tightly pointing downward, and were erect to the painful.

The ropes ran together behind the men and joined to a common rope, which the leader of the three held between his teeth. Perched on his exposed rump was the queen in an elegant black dress, as if sitting on a low riding horse. She had strapped on a frighteningly long, curved dildo, the tip of which now disappeared into the leader's butthole. In her hand she held a whip with which she could steer and maltreat her improvised carriage at will.

Satisfied with her work, the queen clicked her tongue. "Off to the east, my naked horsies!" she exclaimed, and gave the guards in front of her each a welt with the whip on their white buttocks.

A loose movement of her hips also made the guard horse beneath her groan as the dildo drilled deep into his body.

Moaning heavily, the carriage turned right on the white base row and headed directly toward the white king.
