A cruel trick

As I stumble into the locker room I smell a deep bitter smell. It's so different than I'm used to, it's body odor and sweat. I feel a pang of fear hoping no girls are here. My fear is very warranted.

"Oh wow what do we have here... If it isn't onii chan"

My blood runs cold as I realize who is speaking. It's my younger sisters friend josie... She always tries to tease and mess with me. I found out one time she had been cumming in my face lotion for a week!... Least to say she wasn't allowed to come to the house anymore.

She is only 5'6, with dark skin and a petite body. Her hair is short in a raven cut and is pure white. She has on a tight black sports bra and black baggy basketball shorts. Her dark green eyes always look angry when she see's me.

"I... Just leave me alone josie... The teacher said I could... Change here .."She snickers as I try to walk away

"You know.... I have proof your sister cheated on the exams..." Her eyes look intense and serious at mine. I'm shocked by such out of nowhere statement.

The words linger in the air. There is no way it can be true... My sister???... She is so intelligent it is impossible.

"Show me proof... She wouldn't do that!" I hold firm.

Her tiny cute face brakes out in a grin showing her golden braces "oh no boy I don't need proof!... If you love your sister you will crawl to me begging... Otherwise she will never get into college... Such a shame...." She says this all with a cold yet excited tone. She approaches me and I can't help but notice how small she seems... More than a foot shorter than me.

"Get on all fours and clean the smegma from my dirty cock... If you do a good enough job cleaning it I will consider letting your sister off the hook... Oh and don't forget my nuts it's been a week since I've showered and they need a deep clean."

My head is reeling, is she serious? I can't possibly do something like that! She is always lying, I can't trust a word..... But if she isn't?.... I close my eyes as I consider what I might have to do....

"Don't worry you big oaf we have 30 mins until the classes come back... If you give me 100 percent I promise we will be done before then.... Hell I promise to help you with the teachers!"

I slowly lower to the tile floor... It feels cold and dirty... As I look up josie is rubbing her cock thru her shorts... Her green eyes flare as they look onto me with cruel lust.. it looks massive but I can't fully make it out.... What have I gotten myself into?

"Oh onii chan....do you like the taste of fish?"
