In this exhilarating installment of "Medical Tit Consultant," Scarlett Johnson, the insatiable vixen, returns with Preston Philips. She's a vision of depravity, her skinny frame draped in a revealing lab coat, nipples hard beneath. Preston's massive cock strains against his pants, aching for her expert touch. Scarlett doesn't disappoint, unleashing his throbbing member and hungrily swallowing it whole, her tight throat gagging on his size. She's a cock-sucking slut, her big tits bouncing as she slurps and slobbers, her pink pussy dripping with anticipation.
