PRED-837 A black gal sister is treated like a masturbator in a lewd pose that shows her body's sensuality

[Making my big-breasted, tanned, dark-skinned gal sister do humiliating, perverted poses!] One day, my gal sister, who was doing poorly in school, asked me to do her homework to avoid failing a year...! "Please! I'll do anything!" She usually looks down on me, calling me a loser and a virgin... but I'll unleash all my desires on her with this chance! I slowly made her cum while she was in a lewd pose with her pussy fully exposed, and she gradually became my obedient slave... I turned her into a submissive fleshlight that I could cum inside of whenever I wanted!
