The next 24 hours became a blur for Jack. Exhausted by the constant cycle of erection, stimulation and ejaculation, the medical staff quickly decided a drip would be required, so now he had a tube in his arm to contend with as well. He also finally started producing urine, which he had to put into a bottle so that the volume could be measured. Jack initially protested, but given the other option was a catheter and bags so he quickly conceded.
The following morning he was scanned, prodded and probed once more, as well as further blood tests. By late morning he was feeling more like himself and was ready for his chat with Dr McKellar. Jack immediately noticed that she was wearing a rather short skirt, ending a few inches above her knee, though that was probably as much to do with her long legs than anything else. He spent a few moments vividly reimagining one of his fantasies of the past week, which resulted in an involuntary twitch in his cock. The Dr spoke breaking the spell.
"Mr Spencer we have a few things to chat about. Firstly we're happy that the surgery appears to have gone well, with no post op infections to worry about. Your blood pressure is slightly elevated but not a significant concern, but it would explain why you might feel a little flushed at times". Jack figured his eight spontaneous erections over the past 24 hours might also have something to do with that.
She continued "You've lost almost 3 kilos in body mass from just 2 days ago, which is unusual, however it would appear that the combined therapy is burning up your excess fat cells. We've noted your bowel movements would appear to almost match this, and this will require close monitoring for a few days until it settles down. But I think we need to talk about your state of arousal."
Jack knew this was coming, how could he not. He'd spent most of yesterday and last night masturbating in front of a procession of nursing staff, who duly bottled his ejaculate and took it away. "We'd like to do some additional tests, and we'd like you to have daily chats with Miss Collins to properly understand the psychological component. Your semen is in good shape, with high quality sperm and no blood in the emissions. The volume and quantity has, of course, been unexpected."
No shit Sherlock thought Jack. There followed a lengthy discussion, about his sexual habits (he'd not had a partner in over 2 years), and of course his self pleasuring routines, including his sources of stimulation. It was about as embarrassing a conversation as he could remember, and while the Dr was thoroughly professional, he sensed she didn't enjoy it either.
Jack finally got around to the questions he was worried about. Why was he so easily and often aroused! They hadn't discussed any of this before the procedure. He spoke of the vivid dreams, though he elected not to mention that she had figured prominently in them and that this has all started from when he took the medication. "Also Dr, I think my penis is bigger than it was before we started treatment". The silence hung in the room while that waited unanswered.
"Actually Mr Spencer part of the therapy is designed to enlarge the blood vessels and free the urinary tract from the pressure that was causing your pain. So some changes there are to be expected. But let's pay attention to that too" Jack's cock liked that idea and started to swell with the idea of the Dr's attention, tenting his gown in a way that could not be ignored. "Are you aroused now Mr Spencer?" Jack could only nod. The Dr carefully lifted the gown and looked at the stiffening cock in front of her. For a moment Jack swore she licked her lips, but she got up , had a conversation out of the door and a nurse returned with what looked like a measuring tape and some type of callipers.
She used the instrument and tape, made some notes. "I hate to ask this Mr Spencer, but we're going to need to measure your penis in it's flaccid and aroused state for the next few days."Jack understood the need for this and nodded his assent. He'd never measured the girth of his erect cock, but as a younger man had taken the time to know his own erect length. The Dr's note showed 6 3/4" and while he hadn't done it recently, Jack was sure he'd never been more than 6" long.
His reverie over the growth of his cock was broken when the Dr spoke. "Can I ask what prompted your arousal just now Mr Spencer?" For the tenth time in that conversation Jack blushed. " I think it was when you mentioned paying close attention to my cock... I mean penis Dr." He swore he could see a smile briefly flit over her lips and she quickly suppressed it. Her hand brushed her hair behind one ear while she scribbled a note. "I'll do my best to keep our conversations clinical Jack. I don't want you to be uncomfortable." She placed her hand on his forearm, but Jack was immediately aware that was the first time she had called him by his first name. "For now I'm going to ask you to keep capturing your ejaculate in the sample jars for me." He swore there was a little emphasis on "me", at which point Jack reached for the jar beside him just in time to capture the spontaneous eruption. She took the jar, sealed it, made yet more notes and left the room and Jack reached for the packet of baby wipes that he'd been given to clean himself.
