Innocent Latina Stefania Mafra signs up for a unique research study, expecting a simple Q&A, but finds herself in an examination room, legs spread wide in stirrups. Doctor Tampa and Nurse Lenna Lux, clad in white coats and latex gloves, introduce her to a world of medical fetish. They tease her with gloved hands and cold metal instruments, making her squirm. Her natural, big tits heave as she gasps, watching them insert a speculum, revealing her pink, wet pussy. Dildos of increasing sizes are tested, filling her tight cunt, while Lenna's skilled fingers stimulate her clit. Stefania's genuine orgasms are recorded, her body convulsing, juices flowing, in this explicit exploration of pleasure and medicine.
