Good son: sniff your mom´s panties
From Create Your Own Story
You take your mom´s panties from the chair and imediately dive right into it with your face. You inhale deeply, taking in your mother´s pussy scent.
You get your penis out of your pants and start to masturbate. You can´t hold on long and quickly wrap the panties around your dick before you explode. A huge amount of your cum shoots out soaking your mom´s underwear.
You can hear someone in the hallway and quickly put the panties back from where you got them and hide yourself.
You wait for a while and then sneak back to your room.
