Mark was just beginning to appreciate her new form when she felt a deep sting in her mind. She fell squirming onto her bed as the mental changes began. New memories and feelings surged through her head, displacing the old ones, until she was 100% female.
Mark had no memory remaining of her previous life as a male. For all she knew, she had always been a young girl named Marcy, and she had always had an athletic older sister named Jess.
Marcy sat up again and caught her breath, wondering what had just happened to her. Suddenly, "Jess" came into her room without knocking, wearing only her long soccer socks and her smooth lycra sports bra and panties. "Hi, sis," Jeff said with a smirk.
Jeff sat next to Marcy on the bed, leaving her no personal space. Jeff leaned into the nervous Marcy and sniffed her dirty-blond hair. "You know, sweetie, I never realized how beautiful you were..." Jeff wrapped her tan, toned arms around her little sister.
Marcy was scared and confused, but an odd feeling inside her kept her from fleeing or from crying out. What should she do?
