Johnny waited patiently as he felt Clarissa's nice, soft strokes and listened to Sam's sweet begging voice. He whimpered and trembled, and the sound of Sam's nervous voice made Johnny's shaft throb in Clarissa's hand. He kept his eyes on Clarissa's, listening to her sweetly helping her brother beg. Her voice was so alluring, and he was already picturing all the things he was sure she would be saying later.<br/><br/>"Go on Sammie. Help your sister stroke my cock." He emphasised the sentence with a strong grasp at Sammie's leg, his calloused grip rough against his soft skin. Her soft skin? Johnny didn't care much, right now he wasn't sure how he saw Sam. But he had always felt there was a great deal of femininity about Clarissa's twin. Sammie had a good sound to it.<br/><br/>He waited for Clarissa's hand to stroke down before moving his hips up a little, shifting his gaze from Clarissa's to Sam's and watching his eyes. "C'mon Clarissa, let's watch Sammie be a little slut like you are." He briefly checked Clarissa was watching with him, wanting to see her enjoying the view. In many ways her excited, hungry reactions to teasing Sammie were spurring him on. He wanted Clarissa as excited as possible later. "Look at me when you stroke it Sammie. Be proud to be a good slut." This time his grip at Clarissa's thigh tightened, as if congratulating her for already being a 'good slut'.
