A beautiful female dermatologist, Yui Hatano, whose erect penis was seen by the doctor during a diagnosis (MMGH-004)

I want Dr. Hatano Yui, the beautiful dermatologist, to examine the skin of my penis! Dermatologists don't usually have the chance to look at the skin of an erect penis, so I want her to have a good look at it! Plan (1): Schedule the last patient of the day. Since there are no other patients, there should be plenty of time! Plan (2): Go to the clinic on a non-STD basis. Since I want to have sex in the end, I want the doctor to examine my healthy penis properly! Plan (3): Keep an erection throughout the examination. Doctors don't usually look at penises, so seeing an erect penis should excite them! According to the plan, Dr. Hatano is examining my penis, and the way she applies the medicine looks like she's masturbating! Has she already had a full orgasm!? After the two of them are alone in the examination room, I take off her white coat and we start having sex!
