"What? Seriously?! I can't get the vibrator out of my pussy... (sweat) Help me!" My sister, who has been abstaining from masturbation, is having unexpected vaginal spasms after masturbating with a vibrator for the first time in a long time! My sister is taking a bath and asks my brother for help, but he suddenly bursts in! My brother is excited by the sight of his sister naked and has incestuous sex with her in the bathroom!
