sisterly bonding

"Oh little sister you've got yourself into a world of mess." she sits on your chest pinning your arms to the floor with her knees. "You know what you're gonna have to do if you dont want me to tell mom and dad what I caught you doing."

Try as you might you couldn't push her off of yourself. "No!

"Come on, it'll be fun. Just like old times."

"I won't do it!"

"You know I could totally make you right? It's just more fun when you beg."

You tried to throw her off again but failed. "Ask me why I was coming to your room then." She stood up allowing you to sit up. Her evil smile never leaving her face.

You hadn't even thought about why she was coming to see you in all the excitement. "Why were you coming to see me?"

She smiled wickedly "Well last night I was out at the mall with the girls and this really cute guy told us all about this little house party not to far from the mall. So of course we went and who did I see getting drunk and cozy with a boy?"

"No."

"Totally did little sister." She traced her hand along your face. "I saw little sister go into a room with her boyfriend." She saw the look on your face of fear on your face "So being the good big sister I am I went to check up on you two."

"Oh god the girl who walked in-"

"was me." She laughed remembering the look on your face when she barged in on you two.

You swallowed hard "Well it doesn't matter because no one will believe you."

She smiled again and pulled out her phone showing pictures of the two of you, your hand around his hard cock his lips pressed against yours. "And before you get any bright ideas I have copies saved and hidden. Now unless you want me to show this to mom and dad isn't there something you want to ask me?"

Not seeing any way out of this you had **** but to do as she demanded. "...help me be a girl." you said defeated.

"What was that sis? I couldn't hear you."

"Please help me be a girl." you begged more enthusiastically like she expected.

She giggled and gave you a great big hug. "Oh of course I will help you be the girl you always were."
