To be fair the preview of the handjob video looked fake too and she actually did end up using her hand on him. Obviously the lesbian video and blowjob video do look faked from the previews. But given the handjob vid was real, and that fact that people expect to see Stasia actually eat her pussy and blow him in the other videos, it would be pretty ballsy to charge like $50-$75 and have Stasia fake it in camera angles.
Given the angle of her head and the fleeting glimpses of his dick in her hand under her hair, odds are she was actually blowing him. What is clear is that after the hidden bj, Stasia jerks him till he finishes and drips down her hand. People here saying she's uncomfortable are delusional. She's just demure and following the long-money, tease program. The footage of Stasia about to blow him where she says, "now it's my turn," doesn't exist in the final cut of the video.
