I stumble upon my stepsister pleasuring herself in the bathroom and join in with a handjob, which escalates to a blowjob until I reach climax

I walk in on my stepsister in the bathroom, and she\'s already on her knees, stroking my dick. I\'m taken aback, but she doesn\'t hesitate to take me in her mouth, giving me a wild blowjob. The intensity builds as she continues to suck, and I can\'t help but cum, covering her face with my hot load.
