My sister, dressed in clothes that kill virgins, makes a devilish invitation: "Do you want to take a sex video to post?" I get a full erection from the temptation of her panties, so I attack her with the electric massager and vibrator she brought with her. My sister roars like an animal, desperate for my dick. I transform into a carnivorous man and thrust hard, and my sister's body arches backwards, spasming and roaring in response. I clean up the sloppy dick that has ejaculated into my mouth with my mouth.
