Your little sister is on a Skype call with her best friend, but forgets to end the call when they're finished. You watch the screen as Ella fails to notice the call still active, stripping down as she gets ready to shower. You remain hooked to the screen as she returns, freshly clean and shaved. She proceeds to oil and rub her body, getting turned on as she caresses her skin. She gets so hot that she has to stop and masturbate, first getting herself nice and wet before fucking herself to a hard orgasm with her dildo. It's obvious she's thinking about you as she cums, imagining you filling her up. You know you want to.
