"The more violently she's treated, the more she enjoys it" True masochistic sister. My little sister eagerly licks and sucks my erect cock, slathering it with her saliva. Her head is grabbed, and my erection is brutally shoved down her throat until it feels like it's piercing through the back of her head. My sister tears up and sobs, but she smiles happily back at me. She's erotic, obedient, and has a true masochistic personality. Truly the ideal little sister.
