It would happen again tonight she knew. It had happened every night for the last two weeks. That's when she had learned about her son's nightly ritual, which had in turn led to her own. She waited in anticipating for the door to open.
She looked at her reflection in the mirror next to her bed, the moonlight coming in from the window revealed her naked form in the mirror. She saw the look of anticipation and excitement on her face, reveling in the physical responses of her body, while still being amazed as to why.
She had thought of removing the mirror not that long ago. It had been a painful reminder of the times she had watched herself, and her late husband David make love in the mirror. These were happy times, she had thought they would never return. That was until the night she saw her son in the mirror.
(Two weeks ago)
She had woken up to the sound, it was a familiar sound, but one she hadn't heard in over 6 months. The sound of a man orgasming, it was low and guttural, like an animal. Her eyes had opened in the mirror, she saw her body exposed as often happened in her sleep, the sheet having fallen down exposing her breasts, her feet sticking out at the bottom of the bed. In the reflection she saw behind her the image of her 18 year old son Frank.
He stood just inside the door, Frank's eyes were closed and his hand wrapped around his cock, it wasn't overly long, but easily as thick as a can of soda. At that moment it was pulsing, shooting huge amounts of cum onto the sheets on the empty side of the bed behind her. She quickly squinted her eyes as to appear still asleep. Unsure of what to do she continued to watch, and surprised felt her body start to react to a man cumming, just from the mere sight of her.
