My Stepbrother Jerked off on me again while I was Washing up in the Shower

This time, our hot step-sis, with her petite figure and small tits, is caught off guard by her stepbrother while she's busy washing up in the shower. He's been watching her for a while, and his curiosity simply gets the better of him. As she turns around to grab her shampoo, she finds him standing there, already starting to stroke himself. She's taken aback but also a little curious herself. She doesn't say a word, just watches him as he starts to stroke faster and faster. His cock is rock solid, and she can't help but lick her lips. She knows she shouldn't be doing this, but the sight of him is too much. She reaches out, wrapping her hand around his shaft and starts to stroke him too. He moans, his eyes locked onto hers. They're in their own little world, just the two of them. She leans in, taking his head into her mouth, swirling her tongue around it. He groans, his hips bucking forward. She takes him deeper, letting her spit mix with the water from the shower. She doesn't stop until she feels him come, the hot cum spurting out of him and into her mouth. He pulls out, his cock still hard, and she swallows every last drop. But it's not over yet. He turns her around, slamming her against the shower wall. He bends her over, his hands on her small tits, and she pushes her butt back against him. He smacks it, hard, and she gasps. He rubs his cock against her wet pussy, teasing her. She's so wet, she can feel it dripping down her thighs. He slides his cock inside her, and she moans, her body arching against his. He starts to fuck her hard and fast, his cock sliding in and out of her tight pussy. He grabs onto her hips, pulling her back against him, slamming his cock deep inside her. She screams out, her body shaking as he comes again, filling her up with his cum. She collapses against the shower wall, her body spent. He leans in, kissing her neck, and she smiles, knowing this is just the start of their steamy little game.
