Then you back home, your mother, a gorgeous and tall blond about 45 Y.O. cooking something. She still did'nt saw you, and she's unaware that you are pointing your device against her. A blue light hitted her figure, transforming her.
First, her long hair receded to a manly cut and turned to dark. Her shirt and shorts changed in a male type, while her entire body rearranged to a new reality. Her long legs grow more muscles and covered by curly dark hairs, and so her arms. Her pretty breast deflated, but her entire chest expanded, growing muscular and hairy as well, and on her (his?) crotch grows a big bulge.
She turned against you and smiled:
"Hello, honey.. it's all OK?" she-he asked in a deep baritone. Now you can see that on her face she sports a full, thick and curly beard.
"It's OK... m-mom!" You responded.
