"Hi, birthday boy!" Step-Mom said cheerfully. "I'm so excited!" Beside her sat your step-sister who was not so enthusiastic about your birthday considering Step-Mom had made her get dressed in just her lingerie.
Step-Mom explained that, because you were at that ripe and prime age where you were starting to go through some changes in your body, she had a special surprise for you. "And for your birthday, Step-Mommy has decided to give you your step-sister!" she smiled.
Of course this was news to Akira and she started to throw a fit - she couldn't believe what she was hearing. "Your step-sister is going to comply if she wants to keep her bad boy boyfriend," Step-Mom clenched her teeth. She wanted to make sure your first full-on sexual experience was with someone safe. "I think we should keep it in the family," she told the both of you.
