Clarissa sat back almost helplessly as she watched her twin continued to take Johnny's cock. He was so beautiful. So graceful and so perfectly fun and slutty. It almost seemed like Sam was.... better than her? No, it couldn't be. Could it? Could her dear brother have managed to pick up her every teachings and improve upon them? She felt a sting of jealousy hit her as she witnessed the look in both Sam's and Johnny's eyes as they were locked together.<br/><br/>Reluctantly she fell back on her rear as she spread her legs slightly. She then reached her one hand down to her womanhood and proceeded to explore and prime herself. All the while she kept her eyes to her brother, taking in every detail and movement of his. Still her mind raced at the possibility that he could now have become the teacher in their relationship. Teach me, teach me she echoed in her mind.
