I've had a convenient 'nurse on call' since three years ago! My encounter with the nurse Mina happened when I was hospitalized. She was sucking an old man's dick in the emergency staircase at night. I immediately used that to blackmail her, and she quickly gave me head too! Since that day, I've been training Mina, who is weak to pressure. I make her play with my sensitive and delicate nipples and give me a blowjob until I cum, using the big-breasted nurse for sex education!
