Gb's stepsister, Jc, finds herself alone and horny. She doesn't mind her brother catching her masturbating, in fact, she enjoys the thrill. She teases him, touching her pussy, stroking her clit, and moaning loudly. Jc knows her brother is watching, and it only turns her on more. She wants him to join her, to touch her, to fuck her. But he holds back, torn between desire and fear of crossing boundaries.
