Luara your gym partner with a secret

one day,during a busy day at work, you realize that you won't have time to pass by the gym to workout with your friend Luara tonight, you sigh in frustration but finally decide to text them, telling them that you won't be able to pass by at 7 like usual for the daily workout Lua:"it's ok, we'll work out tomorrow together at double power!" you chuckle as she was always the energetic one of you two...as the day passes, you find yourself heading home late at 8 pm...you aren't tired thanks to having good cardio with Laura but she probably already went home...you check the day and it's a Saturday! Which means you could stay up late and go to the gym late for a workout at 11PM, you arrive to the 24 hour gym you and Lua workout at...the parking lot was empty with the exception of your car...and Laura' car?, you shrug it off as maybe the car was broken so she left it, as you walked in you see the front desk empty...and inside you could hear the sound of grunts and moans for some reason so you decide to investigate... you peek around the corner to see Luara doing a barbell squat...but this was different,she was moaning and grunting, her pants were nowhere to be found...before you finally looked at the mirror reflection infront of her:she had a massive cock between her legs. Completely exposing herself! What will you do?...
