Cum Medicine - S01 E01

Read Story: SEASON 1 EPISODE 1

My wife Kellie and her sister Kristin sat in the doctors office waiting for him to return with results for Kristin's recent blood work. She had been losing weight recently which wouldn't be a big deal if she wasn't already so petite. Kellie was worried enough that she had demanded that Kristin see the doctor.

Kellie was shocked when the nurse had weighed in Kristin at 87 pounds when they arrived. She seemed to be losing an addition pound every week or two. She was very short, under 5' tall and was so skinny you could see her ribs. She had a tiny, cute butt, and very small tits that we're little more than perfectly shaped 1/2 tennis ball-like protrusions from her small 28a chest. She was in nursing school currently but didn't have a very busy work schedule, as she was in between semesters.

Kellie, on the other hand, was taller at 5'4", and while also very skinny, with a rib cage and chest that were also very small at 32b. Both girls were blonde and had very cute faces. They were only 2 years apart in age, with Kellie being the older of the two at 26.

The doctor entered the room with a folder and a concerned look on his face. After sitting and clearing his voice he spoke, "Kristin, after doing your bloodwork and looking at Kellie's previous bloodwork, it appears you both have a genetic disorder. Kellie, it seems that you don't have any symptoms which we have a theory about. I'll get straight to it. Kellie, I believe your husband's ummm... dna... has been helping keep you healthy. The odds of his dna being a perfect match to counteract your condition are simply incalculable. We'd like to run some tests on him as soon as we are able. Another donor like him might be a 1 in a million occurrence."

Kellie Interrupted, "that is good to hear doctor, but how does this help Kristin?"

The doctor paused before saying, "Well... it doesn't exactly... but there may be some non traditional ways to improve her condition. We can do a bunch of further tests, but I suspect... that your husbands... well... sperm... might be allowing your body to process nutrients that it would normally reject. I realize that this is difficult subject matter.. if you're ok with it I'd like to ask a few questions to verify our theories are correct."

"Wow... ok... Of course, doctor, anything to help my sister!", Kellie replied.

"Excellent. Again, some of these question might be awkward, but it is in your sister's best interest if you answer truthfully. Now, how many times per week do you and your husband have sex?", the doctor finished.

Kristin turned her head slightly toward Kellie, very curious as to the answer. She was a virgin and had always been attracted to Ethan, Kellie's husband, and now she was going to get some exciting insight into their sex lives. Kellie responded, "well... ummm... do you mean... Intercourse, doctor?"

The doctor replied, "yes, we'll start with traditional intercourse." He sat ready with a pen and paper to mark on a chart on his desk.

Kellie, blushing a bit, looked down at her knees and replied, "maybe 3-4 times per week"

Kristin couldn't hide a slight smile. She had suspected they fucked a lot.

"Excellent. Very healthy.", the doctor replied. "Now then, do you ever engage in anal sex, and if so, how often? You see, as with suppositories, the absorption rate of medicines in the anal cavity is nearly 5-7 times greater than ingestion."

Kristin's eyebrows raised and she stopped smiling. She had no idea that she would get these kinds of insights today. She was sure her sister didn't allow Ethan to fuck her ass.

Kellie closed her eyes, still looking down, reminding herself she HAD to be honest, "ummm... well... yes, doctor, I'd say we do that... well... once or twice per week."

Kristin couldn't help but allow her jaw to drop slightly as her eyes opened wider. she thought to herself.

The doctor made a note in the chart and replied calmly, "Thank you Kellie, I know the subject matter is difficult. I'm just trying to get a sense of how you're absorbing his DNA, which is keeping your symptoms at bay. Just a few more questions. Now again, we're trying to establish a pattern of ways you are absorbing your husband's sperm, as I believe his DNA has been keeping you healthy. How often do you perform oral sex on your husband?"

Kristin started to feel aroused imagining what the answer might be.

Kellie sighed. This would be much easier to answer if her sister wasn't in the room. "Well... I think.. maybe once or twice..."

The doctor interrupted, "excellent thank you. Once or twice per week." He began marking it down when Kellie interrupted him.

"No doctor, I'm sorry... I meant... well. I meant... once or twice... per day..." Kellie corrected, quite embarrassed and visibly blushing.

Now both Kristin AND the doctor looked shocked.

*...Excluding foreplay from intercourse." Kellie finally finished. She felt she might pass out from embarrassment as the doctor marked his chart after a shocked pause.

Kristin also couldn't hide her shock. Then she started to feel angry. She spoke up, "Kellie... this sounds like abuse. He shouldn't be asking you to do that so much. Maybe you could use some counseling...?"

Kellie corrected her quietly and almost guiltily, "No Kristin, I'm the one that initiates it each time. In fact, there are some times where he seems too tired, but he knows I get upset if he doesn't let me do it."

Kristin stopped talking. Her sister was a sex addict?! This didn't make any sense! She had only dated a few guys before Ethan, and didn't even have a single boyfriend in high school! She wasn't exactly the town slut before she got married!

The doctor interrupted her train of thought. "Kellie, In nature many species crave things that are necessary for their survival. It is highly probable that subconsciously you have been craving the cure for your condition. Now just a final few questions."

He continued, "First, how often did you perform oral sex on previous partners?"

Kellie thought for a second out loud, "I only had 3 boyfriends before Ethan... and I didn't really enjoy oral sex back then. Not often at all! It just that I enjoy it so much more with Ethan."

Kristin was beginning to feel flushed and her pussy felt tingly, she could also feel her nipples getting hard. She glanced down self consciously at her shirt to see if it was noticeable. Thankfully she always wore extra padded bras to make her chest look bigger.
