I'll teach them how to use the toys.

I watched through the screen as their initial movements lacked the intensity the room demanded. Their nervous laughter bounced against the soundproof walls, creating an echo that clashed with the gravity of the leather and steel surrounding them. It was clear that modesty still bound them, that the shyness of the forbidden held back their hands. I let that naive scene unfold for a few moments longer, savoring the power of knowing that with a single word I could transform that hesitation into absolute submission. I brought my lips to the microphone, determined to break that innocence.

"Enough touching," I intervened, abruptly cutting off their laughter. "Sofia, put your friend against the leather wall, with her arms up. I want the riding crop to find its real place."

They got into position. Sofia's friend rested her forehead against the padded panel, exposing her entire back and profile to the camera I had adjusted for a close-up.

"Not on the back, Sofia," I ordered, lowering my voice until it sounded almost imperceptible. "Aim for her breasts. I want the tip of that crop to brush the tips of her nipples first, and then... a sharp strike. Let the red of desire begin to mark her skin."

Sofia swallowed hard, but obeyed. The first strike was soft, a smack that made her friend let out a gasp of surprise.

"Harder," I demanded, while using the zoom to see how the nipple hardened from the impact. "And now you, my friend, take the whip. Sofia, turn around. I want the whip to land right on her sex. I want the leather to kiss that highly sensitive area with medium ****. Strike until the rhythm of your breathing is the only thing that can be heard."

The basement filled with a rhythmic sound: the swish of the crop and the crack of the whip striking bare skin. There was no more laughter. Their faces showed absolute concentration, a mixture of exquisite pain and a submission that was pushing them to the edge. I saw how the skin of their breasts turned an intense pink and how Sofia's legs trembled every time the whip found its target between her thighs.

"Don't stop," I told them, as I myself felt the tension in my hotel room reaching a point of no return. "I want to see those marks. I want that when you look in the mirror tomorrow, you remember exactly who was directing you from a distance."

I kept watching as the aggressiveness of the game increased, how their bodies reacted to each directed impact, turning my basement into a laboratory of sensations that I controlled with a simple voice command.

The rhythm of the strikes became hypnotic. On my laptop screen, the contrast of the red marks on their white and tanned skin was a moving work of art.

"Rotate," I ordered coldly. "Now Sofia takes the impact on her inner thighs, and you, aim for the base of her buttocks. More ****. I want the sound of leather against flesh to be louder than your moans."

They exchanged roles with a feverish urgency. Their bodies were no longer dry; sweat glistened under the red LED lights, and their chests rose and fell in an effort to catch their breath. Their arms began to fail them, the fatigue from the physical effort and the sensory overload was evident in the way their hands could barely hold the leather handles.

"Stop," I said, and the silence that followed was almost deafening. "You are tired, but the game does not allow for weakness. We are going to let chance decide the next level. Face each other."

They looked into each other's eyes, with messy hair and flushed cheeks.

"You are going to play rock, paper, scissors. The winner will be my right hand, the dominant one. The loser... will become an object at the disposal of my will. Begin."
