Cum Medicine

Chapter 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.
