Take a peek.

An uncontrollable urge washes over Alvin. Images of his naked mother enter his thoughts seemingly from nowhere in particular. Her long, blonde hair; large, shapely chest; hourglass-like figure; and round, plump rear. These are thoughts that normally he would think uncomfortable, vile and disgusting, however, something inside him told the opposite.
He was entranced by her forbidden allure and needed have her for himself.

Approaching the door, Alvin peeks inside. As his eyes adjust, he sees a shape hiding beneath bundles of blankets. Without hesitation, he slips in for a better view. Alvin creeps within a foot of the bed. Alisa turns to face him, very much ignorant of her son's presence. From this close, he can see her youthful face. Her lips waiting to welcome his. Although, her lips could also be awaiting something else entirely different.
