Caught by Rick

Kate had never seen her sister completely naked, let alone like that. It took her by surprise. She could see Jan's bare athletic ass clearly in the candlelight. Her head was bent down in Rick's crotch while her ass was sticking up in the air, partially exposing glistening wet pussy lips.

Kate looked up at Rick again. She realizes his hands are tied above his head to the bed post and there's a ball gag tied across his mouth so he couldn't talk. He had a wild look on his face as he stared down on Jan's head bobbing up and down on his crotch.

Kate stood in the doorway completely stunned. An arousal started to creep across her body. She'd seen a porno before but this was completely different. Her sister was sucking the dick of a man she'd dreamed about multiple times. She was also taken aback by how sexy it was to see her sister's naked cooch sticking up in the air. Almost instinctively Kate's hand ventured to her own crotch as she stood there watching.

Her movement must have caught Rick's attention as his eyes moved to the door catching Kate standing there with her hand between her thighs. He jumped in surprise, but his bindings held him still and the ball gag muffled his warning.

Jan lifted her head with a slurp as his erection was pulled from her mouth. "Quiet! Someone might hear you!" Then she dropped her head and went back to work on his knob.

Rick's eyes stared at Jan as she kept up her blowjob, then jumped across the room at Kate. Going back and forth, unsure what to do. He was both aroused and fearful for being on display in such a compromising position.

Kate's open mouth turned to a devious smirk. She realized Rick was helpless to do anything. He had to sit there as his wife continued sucking on his erect cock and his sister-in-law watched it all happen. He couldn't cover himself. He couldn't even warn Jan. He just had to sit there with one of the biggest erections Kate had ever seen, and try to hold off an orgasm that was guaranteed to eventually come.

Kate felt a sense of control over Rick in that moment. He knew she was there, but he was helpless to stop her from soaking in the view of his fully exposed body. She had dreamt of seeing that thick dick of his and here it was on full display as her sister kept sending him into round after round of pleasure. Kate stood there with her eyes fixed on him and a face of desire. He knew instantly that she was going to use him for her entertainment. The feeling of control bubbled up an extra excitement inside Kate.

Her hand started to rub even harder on her own crotch. It wasn't enough so she ran a couple fingers up her leg to pull aside the silk pajama shorts and lacy panties she had wore to bed. Finally, she felt her own warm pussy and she began to vigorously massage it. Her wetness began to come quickly with all the excitement as she leaned against the door frame.
