Melvin stood in his underwear as he folded the last piece of laundry from the basket. His father and new stepmother were away on their honeymoon, leaving the house under the supervision of him and his stepsister, Anna.
Forever the people pleaser, Melvin adhered strictly to his father's solitary rule of 'no parties' and was working tirelessly to spruce up the house for their return. He loaded all the neatly folded laundry into the basket and bent over his lanky frame to pick it up. His first stop was Anna's room. On the way, he heard Anna shut the door to the upstairs bathroom and the shower begin to run.
He began unloading her laundry onto her bed. As he set down the neatly folded pile of her panties, he mumbled to himself,
"you are full of surprises, Anna."
They were all incredibly skimpy, which Melvin found inconsistent with her reserved personality. After unloading the last pile of Anna's clothes, he grabbed the basket and turned to leave, when suddenly, he noticed something in her desk drawer that had been left ajar. He quietly slid the drawer open further for a closer look. It was her journal! He picked it up and his eyes quickly darted to the door as he listened for the sound of the shower. It was still running, but he knew his eco-conscious sister was not one to waste water, so she wouldn't stay in for long.
He quickly began thumbing through the journal, skimming as fast as he could. Most of the content was rather boring, containing several entries about boys she liked at school and rants about drama in her friend group, until Melvin started spotting some words he didn't expect. Passages containing 'Cock'... 'Pussy...' 'Cumming', just to name a few, demanded further inspection. He gave one of the entries a closer look and was astonished to realize he was reading one of Anna's handwritten erotic stories!
