The leader is tightly bound on the operating table, legs spread wide unable to close. The super large silicone penis is fully inserted into the body, deeply pressing against the most sensitive spot. The leader continuously emits suppressed moans of pleasure, green gloves continuously dig and expand the anus, cooperating with vigorous thrusting to forcibly stimulate the prostate. The semen extractor tightly wraps around the experimental subject's continuously swelling and purpling slutty penis, mouth overflowing with "about to cum". Full protection, solely to safely collect the milky white virus about to spray.
