He walks by. Let Sabrina continue

The man in the trenchcoat walks by without looking into your car, and Sabrina breathes a sigh of relief, her body relaxing. The train begins to move again, pulling away from the station.

"Oh my god John he almost caught me!" Sabrina whispers excitedly. The close brush with being caught has clearly excited her, and her hands are already sliding back down into her panties. You're still recording as she finally starts to push her panties to the side, her delicate pussy coming into view. You groan internally as you watch Sabrina start to rub herself again, wishing you could reach out and take a piece of her.

"Fuck John this is so hot, I feel so turned on, oh my god," Sabrina whispers softly, her eyes closed as she nears an orgasm. Her legs start to shake as pleasure overcomes her and she moans softly, trying her best not to be loud. "Ahhhh, I'm comingg," Sabrina says, her head tilting backwards and her legs spreading as she fucks herself with her fingers through her climax.

You keep recording as Sabrina comes down slowly from her high and opens her eyes to look at you. There's lust in her eyes, and you wonder if you can pounce on the opportunity...
