A knock on the door...it's Mom

Brian laid on his bed in a daze. The orgasm he had just experienced was unlike any sensation he ever felt. A euphoric feeling with tingles going through him as his heart rate was starting to slow down. The incredible feelings helping him ignore the fact that something still didn't make sense. So much of this felt unnatural. His enlarged penis, his thoughts about his sister, that...orgasm.

The reality is that it was only the beginning. This mysterious and supernatural 'thing' that has inhabited Brian's body was only growing its ability. While it's unknown to what its intentions fully are, so far it was lust and corruption. Brian's penis was no longer a simple organ with normal functionality. It was much more, and no longer controlled by Brian's body. His world was about to change.

While still recovering from his orgasmic daze, Brian had completely lost track of time during his new pleasurable experience. While his penis had provoked this memorable, mind-blowing, orgasm that left in panting for air his Mother, Allison had waited. It had been at least 5 minutes since she had called up the stairs for breakfast. She had the thought that she should check and make sure they were awake.

A few moments later, a knock on the door. "Brian?" She said softly.

Brian hadn't moved in over a minute since the cum eruption he endured just before it. In any normal circumstance, Brian would have leaped off the bed and concealed his softening cock. But somehow, he didn't react. His cock had sent such pleasurable waves through him recovering from his climax, he didn't even hear his Mother. The knob turned as the door opened and she peered in. She was wearing a thick blue robe with only her white cotton bra and panties underneath. It did an admiral job of covering up her body which was quite attractive at her age. She had moderate curves, and her dedication to running on the treadmill in the basement 4 times a week kept her figure tight.

"Brian? Are you up? Oh....." her eyes finally met her son's body laying on his bed. But they very quickly focused on his exposed penis laying on his hip. Her eyebrows squinted. Was that..? Could it...? But she had seen it before, it had been years but it didn't look like...that? Those were the questions went through her mind as she subconsciously walked closer to the bed. Each step closer, more details began clear to her. The shape, the veins going down the underside of it. As she took another step, she swore it slowly moved over just an inch. She blinked and tried to get a hold of herself. "He's your son, you can't look at him like that..." she silently told herself. But the next thing that caught her eye was the dark circles of wet spots sprayed around him on the bed sheet, then the white globs on his chest and shoulders. That was his...cum! Her jaw was slightly open as her feelings and confusion were taking over. The more she looked, the more this numbing feeling came over her mind. Staring at the head of his penis, as if some speechless connection was happening between them.

The cloudy haze in Brian's head began to clear when his blinked open, and suddenly his Allison was looking down at him with this bewildered look on her face directly at his crotch. In a somewhat calm but confused tone, he spoke out "Mom?"
