Julie finds another letter from the blackmailer.

Julie closed her bedroom door behind her and quickly locked it. She reached into her purse and removed the photograph the blackmailer had shoved down her top. She wondered how many pictures the man had, and what he was going to make her do to get them. Julie slipped the picture into her diary then put it back in it's hiding place under her bed. When she stood up her eyes caught a white envelope on the bed. It looked the same as the one from her text book. Slowly she opened it with trembling hands, she was afraid and excited at the same time.

The letter was another one from the man. This time the instructions were different. She was half way through reading when a knocking on the window made her freeze. Standing at her bedroom window was a man wearing a black ski-mask. It covered his entire face and completely concealed his identity. He pointed to the letter with one of his fingers. Julie read the remaining part of the letter. The blackmailer wanted her to lay on the bed and masturbate for him to watch. Julie heard another knock and this time the man was holding 2 pictures up to the glass. The girl nodded her head in a silent yes.

Mark watched with excitement as Julie slowly undressed. First she pulled her blue sweater off over her head, her breasts bounced as she removed the sweater. He continued to watch, now he felt his cock beginning to grow, just like the first night when we had watched Julie give her boyfriend a handjob. Julie took down her pants and underwear at the same time, revealing a completely shaved pussy. She unsnapped her bra and it fell forward, her large tits popped out.

Watching was getting to Mark, just staring at her naked was enough. He quickly unzipped his fly and began to tend to his raging erection. His hand moved quickly up and down the shaft as he watched Julie climb on to her bed. Then she rolled on to her back and spread her legs. She made sure to face her open pussy toward the blackmailer. Julie's fingers massaged the outer lips of her vagina, then she slid one finger into the opening. She spread the lips and felt her wetness, she was surprised to be so aroused by the situation. Julie was discovering that she had a little exhibitionist in her. The thought of being watched while she finger-fucked herself drove her on.

Mark worked his cock while watching Julie playing with herself. Now she had one of her hands on her breasts. She was pulling at the left nipple, rolling the hard, pink nub in her fingers. Her other hand rubbed hard and fast over her swelling clit. She pushed her head back into the pillow and moaned aloud. Even through the window Mark could hear her pleasure filled sounds. His hand was stroking faster now and he felt an orgasm on the verge. He came quickly, shooting his hot, sticky cum all over the side of the house.

He cleaned up and looked back in the window. Julie was going at it hard. Her eyes were closed and her mouth was wide open, her body rocked back and forth on the bed as she rammed her fingers deeper. Mark felt a trace of life in his dick again, but resisted the urge to play with himself again. Instead he placed the two pictures on the window sill and took off. Julie finished masturbating with a huge orgasm, that sent chills through her whole body. She laid on the bed for a while, shivering from the pleasure before she fell asleep.
