I caught my stepsister at work web cam she fucked herself and squirted from her pussy

In the evening, my parents left on business, I wanted to go into my half-step sister's room. Her room was surprisingly quiet, going to the balcony, I was shocked, my step sister was fucking herself with a toy in web cam chat with some guys. I took out my penis and started masturbating on her. In the end, I finished at the same time as her squirt.
