You break into Emma's e-mails to find out how she got your sister to agree to everything

You are very curious how Emma convinced your own sister to fuck you. You dig through Emma's texts and don't see any clues. You check her Facebook messages and nothing. Then you break into Emma's emails to find what you are looking for.

You see the email Emma sent to your sister.

I apologize if this is out of line, delete - forget about it, if it is. Continue if you dare...

Remember that night when you told me your fantasy... I know you were VERY drunk... so maybe you don't remember. but you told me about how you were jealous of me... about John...

Well it's been weeks and I haven't been able to get that conversation out of mind. I have some ideas of how... maybe we could all have some fun. John's been asking me about a threesome... and with the help of a blindfold John wouldn't ever even need to know it was you.

love,

Emma

Your sister's rely was simply, "I'M IN."
