The fire door allowed a good view into my brother's attic bedroom.

Sitting back in his chair, his jeans at his ankles, his girlfriend on her knees before him, head bobbing up and down in his lap.

Sensing me, she glanced at the window her eyes locking on mine.

She held my eyes as she continued her efforts, then held up one hand, making the ‘wanking’ gesture, she pointed at me.

Opening the door, I stood watching her efforts, masturbating my hard cock.

Now her eyes stayed locked on my cock, watching, waiting until I spurted.
