A professor messing with a student?Career ender.Him being my stepbrother only makes things worse.

Just when I think nothing can break my boredom…My phone chimes.Sext me.Two naughty little words.The dirtiest text I've ever received.Even though it's clearly not meant for me, I'll play along.I'll pretend I'm the adventurous vixen he thinks I am.
Tomorrow, I can worry about the truth.
Number one - I'm not a student.
Number two - I'm his professor.
And the most important fact...
Number three - I'm soon-to-be his stepsister.
More than my career is at stake here.So is my heart.What can I do when there's no good choice?
