Jerking my cock watching my stepmother

Rachel is a controlling stepmother to her stepson. She works very hard at an office all day when she returns home her stepson is waiting. She quickly tells him she is going out with her girlfriends and he is to stay home. Her submissive stepson never argues with her. Rachel tells him she is going to shower. She enters the bedroom closing her door part way. Her stepson sneaks up to the door to peek at her undressing. Rachel knows he is watching and slowly removes her tight business clothes to reveal her bra, garter and stockings. She then slowly removes those. She goes to the bathroom and starts the shower. He watches her rub her wet body with soap and jerks his cock.
