I was just chilling in my room when I heard my step sis moaning loud as fuck in the bathroom so I go check what’s going on and she’s masturbating in the shower!
I take out my phone and start recording her and told her I was going to show everyone I know! I blackmailed her and told her if she didn’t help me out I would post the video everywhere.
She eventually gave in and started stroking my rod and then dropping to her knees and taking it in her mouth.
Then I told her I can’t cum unless I fuck her, so I took her to the living room and pounded into her pussy until I busted in her mouth!
