She just smiles

You should know by now, I looove to be the brat. After I sit down on the machine, she leans over to my ear to whisper
And I love your way of punishing me. Fucking me like a cheap slut and use me just the way you want. I can feel my dick getting hard in an instant. I look and her and start my set. I can feel her hand on my chest.

Such a strong man. She whispers again and I finish my set. Your turn. I put my towel infront of my shorts to hide my erection in the gym but Luna clearly knows what's happening. She starts with her set as I lower my lips to her ear.

Continue like that and I will punish you. Afterwards I will take you home so we can fuck all night. I stand up but feel her hand on my cock. She massages me a bit behind the towel as her hand grabs pretty tightly around me while she is training. My eyes wander around the gym. Quiet a lot people left so mostly the hardcore people who are always here, not just around New Year are still training. I enjoy her small handjob that only lasts as long as her set.

Are you still having your period? I ask quietly while still watching the gym. An idea forms in my mind and with any second going by, I know I want to make something real out of that idea.

Nope, ended yesterday in fact, why are you asking?

I look down onto Luna. Her eyes grow wider the more I can feel the smile on my face.

I don't know if I want to like that smile or if I should be afraid. I hear Luna say before guiding her to the lockerrooms and showers.
