Her Best Friend Becomes Her Sir (F for M)

[Usani]

Samantha Lynette has been fantasizing about being a sub ever since she tarted exploring the Kink community online when she was 18.  After a year she's been craving it more then ever.  But, she's not fantasizing about just anyone dominating her, she's been fantasizing about her best friend.

They both go to the same College for art and music and even share a dorm.  They have been best friends since they were kids and shared everything.  But, now when she sees him she becomes hot and bothered.  So, what happens when he hears her moaning his name in her sleep and finds her touching herself, what does he do?
