An old friendship

EC's Erotic Fiction - www.asstr.org/~caligula97030/

The history of Emily and Monica went back almost two decades.  They lived next door to each other when they were growing up and rode the bus together.  They had an ordinary friendship until they started high school and Emily's dad built a large tree house for her younger brother.  He spent one afternoon there and never entered it again, so it became Emily's favorite hideout.  Within a few days Monica started going up there as well.  They could pull up the rope-ladder after them and close the hatch-door, so they had complete privacy.  The games they played in their new hideout started innocently enough, but that quickly changed.

Monica had a birthday shortly after the two started hiding out in the tree house.  After the other party guests had left, Emily invited Monica over to her back yard for a "special after-party surprise".  They shut the door and Monica went over Emily's lap for her first birthday spanking.  Emily was almost as nervous as Monica, so the spanking was short, clumsy, and not very hard.  But the idea of a birthday spanking stuck with Monica and she wanted more.  Over the next couple of weeks, she kept dropping hints until finally Emily realized what she was after.  The second spanking was much longer, and more importantly, delivered on the bare.

Monica and Emily both dated other people in high school, but they continued their clandestine sessions in the tree house.  They looked forward to seeing each other, precisely because they were not in a formal relationship and thus never had the chance to get bored.  When they were alone, Monica was always a "brat" around Emily, and her bare bottom paid the price.  When Monica turned 18, Emily gave her "a special outfit for my special naughty girl."

Going to separate colleges, seeing other people, and being in a profession in which they were rivals did not affect their relationship.  Their time together, no matter how brief or sporadic, was something they both needed.
