Sam could feel the hand on his ass getting more insistent, and he could feel Clarissa's hand in his getting more excited. And it all was just so overwhelming. He was glad he was taped down so tightly, not only because he didn't have to admit how he felt about this but also because of how it might ruin things before they start. Clarissa deserved this. He'd rarely ever seen her so happy, and he loved her so much. And then....oh that hand on his ass.<br/><br/>The more rough it got the more Sam smiled, the more he gave Johnny shy little glances that quickly looked away. And when the pinch came a little yelp that caused him to press himself into both Johnny and Clarissa more as his body tried to jump away from it, a wiggling little gesture in his high heels that nearly made him trip and fall, although he recovered with another nervous giggle, that turned into a blush as he was called one of a pair of perfect little sluts. He glanced at Clarissa with a little smile at that. They'd accomplished what she'd set out for when they started this. She wanted them to be fun and slutty when they went out. Now they were perfect!<br/><br/>He cleared his throat and whispered "Clarissa's<em>really</em>good." With both a loving smile to her and an enticing one to Johnny. "She's the best." He gave his sister a loving squeeze and leaned in and kissed softly at her neck.
