Mrs. Watson is back!!! Today She is conducting an experiment on a male cock. She has a subject naked on Her examining table, and She begins to gather research on how the cock works. She measures the penis at rest...She takes the male's pulse....by listening to his heart, and also listening to his penis. She measures the differences that occur as She masturbates the penis slightly...stopping to re-measure. She also makes notes on his increased heart-rate as She continues to massage he penis. She observes pre-cum...and stops to write down the time it appears. She also notes that penis size, and heart-rate increase as She manipulates his balls. She then vigourously Jerks the penis until ejaculation occurs....makes note of the time...and assures the subject that his "time to ejaculate", was completely normal. She washes the cum off Her hands...and thanks the subject for helping with the research WARNING : This clip contains severe footage of a lady being in complete and total control of a boy's cock!!!!!!
