Rob Piper, Valentina Nappi Star in 'My Personal Trainer' for Dark X

LOS ANGELES — Rob Piper provides a very particular workout for Valentina Nappi in “My Personal Trainer” for Dark X, now streaming.

Nappi is a “beautiful, bored and rich housewife who loves to tease and flirt with her personal trainer (Piper),” a rep said. “During a workout session, Rob is trying to be serious but cannot help but give into Valentina’s seduction by banging the daylights out of her, burning more calories than any boring cardio can.”

Piper praised his costar and studio. “It’s always a pleasure to work with Dark X and I couldn’t ask for a better workout partner than Valentina,” he said. “She truly is gorgeous and extremely sensual. We had a fantastic time together and it shows.”
