Your penis is STILL massively swollen from those sketchy pills you took, so Mom has finally agreed to let you see a doctor. Since it's hard for you to even stand up with such a large cock, Dr. Nash pays you a house call. Dr. Nash is a straight-shooting professional who manages to control her shock at seeing such a huge dick, but she tells you honestly that this is the most extreme case of penile swelling she has ever encountered. After checking your heart and lungs with her stethoscope, she declares you to be otherwise healthy. Dr. Nash puts on latex gloves, removes your underwear, and begins a preliminary examination of your penis. While touching the swollen organ in various places, she asks about the sensation, the intensity of your orgasms, and the size of your ejaculations. She tells you that she needs a semen sample to send to the lab, and she proceeds to lube you up. Dr. Nash puts you at ease, continuing to chat while she masturbates you. After several minutes, she apologetically confesses that she didn't schedule enough time for this appointment and asks if there is any way of expediting your ejaculation. When you tell her that Mom always shows you her tits to make you cum, Dr. Nash suggests that it might be enough if she were to show you her bra. She removes the top of her scrubs, revealing a pretty but conservative bra, and continues to massage you. When you don't cum after a few minutes, she agrees to remove the bra and show you her tits. Having already crossed this line of professionalism, she barely resists when you ask to tit fuck her. Dr. Nash gets on her knees and wraps her DDD's around your super-sized shaft, pushing her tits together with latex-gloved hands. When it's time to cum, she has you blow your huge load into a jar. That's one impressive semen sample! Dr. Nash, a bit flustered now, puts her clothes back on while she assures you that you're probably fine, but she definitely wants to see you for a follow-up appointment, just to be safe.
