Miranda, late in her pregnancy

A very pregnant belly walks through your door, followed by the woman it's attached to. She's a pale woman, in hair and skin, though her cheeks are flushed. She's wearing a floral maternity tea dress and flats, and carries a purse to match.
"Miranda Anderson?" You ask.
She nods.
"Come have a seat over here." You pat your examination table.
She walks across the exam room, and you see a long, hard erection dance from side to side in her dress from beneath her belly. She sits on the paper of the table.
"What brings you in today?"
"Um, well it's. . .Ah. . ." She sighs, and simply pulls up her dress in resignation. With her dress drawn up to her pert breasts, she looks down in embarrassment at her rock-hard cock standing at attention, drooling precum into its pink, translucent condom. It's a foot-and-a-half long, and it matches the curve of her belly nearly perfectly, pressing up against it. Her kiwi-sized balls rest heavily on the table. "It won't go down."
You study her gorgeous penis with a clinical manner. "Your erection won't stop? Oh, you can lower your dress."
She looks up at the ceiling and grits her teeth. "Well, it's not that really. I keep getting them. The baby keeps putting pressure on my prostate, and it's driving me fucking crazy. I'm not taking anything to keep my penis soft, because I don't want to hurt the baby."
"Yes, that's a fairly common problem." You take some notes. "There's not much to be done about the stimulation, but I have a cock softener I prescribe for pregnant women. While you're here, I'd like to perform the regular exam."
She jumps and gives a soft grunt. The baby must have kicked. "Yes, that's fine."
You wash your hands and put on your gloves. "We'll start with the genital exam. Open your dress, please."
She unbuttons her dress and stands holding it open as you sit on the stool in front of her. Erect penises are always easier to examine. You peel the condom off of her penis and drop it into the wastebasket. She flinches, but maintains her composure. You palpate the shaft, draw back the foreskin, check for rashes, and it all looks good. Then you produce your speculum, and insert it into her urethra. She sucks air through her teeth. You apologize. "I'm sorry, I know this part isn't fun." You shine your penlight down her dickhole, and check the walls for abnormalities. It's very tight, due to the erection, but you're confident that it looks healthy.
Suddenly she grabs her belly "Ah fuck!" she cries out, and her dick spasms. A huge glob of cum shoots out and hits you right in the forehead. "Oh my god, I'm so sorry!" Her dick is still twitching, pumping out semen.
You try to console her. "That's fine, that's fine. It could happen to anyone. I suppose that's the root of the problem, isn't it?" You wipe off your forehead, remove the speculum, and then clean off her penis. "Well, that's the genital exam complete. Everything looks just fine. If you'll please, turn around and assume the position for the rectal exam."
She turns around and leans over the examination table, hiking up her dress. Her lily-white ass is thrust into the air, atop her long, graceful legs. Between her spread legs hangs her slowly swinging balls, and behind that her huge belly with her erect dick straining against it.
You apply lubricant to your gloved finger. "Just gonna check around the area." You pull her cheeks apart and look for abnormalities around her pink asshole, rimmed with delicate, blonde pubes. "Okay, I'm going in." You press your finger against her anus, and gently push in. She whimpers softly. You check the walls of her rectum, then push forwards and make contact with her prostate. You press down, and she cries out and arches her back. You watch as her balls draw up and drop down rhythmically. "Sorry, you must be pretty tender."
"Aaauhuh. . ." is all she says in response, and more semen drips from off her belly. She clenches her asshole down on your finger and begins rocking backwards and forwards, grunting when your gloved finger hits her prostate.
"We're almost done."
