Forgot to turn off the camera, stepsister got caught fucking her pussy

Forgot to turn off the camera, stepsister got caught fucking her pussy, I left my go pro in my stepsister's room, when I got home, I looked at the recordings on the camera and saw how my stepsister was fucking her pussy with a vibrator. After I took out my penis and started jerking off on my step sister, I haven't had such an orgasm for a long time. Now I leave the camera on purpose
