Ibuprofen and prostaglandins

The reason to overlook this penis in uterus absurdity is because it's pretty obvious she isn't entirely human anymore and since he isn't human his ejaculate isn't the same.
With normal humans there are a couple problems with it. The cervix and prostaglandins. Yes the cervix can dilate enough to pass a baby thru it, but it's generally a slow and uncomfortable process requiring the right hormones to begin. Prostaglandins, found in seminal fluid, introduced into the uterus within just few minutes cause nausea and vomiting, fever, diarrhea and cramping. Interestingly it is also prostaglandins which are used to initiate cervical dilation.

Medical stuff:
Fracture = broken. We have lots of terms to describe the fracture, but a fracture is a break.
People can walk on a broken ankle if they are tough enough to take the pain and the tibia is not where the fracture is.
She would have had an x-ray about a week after the surgery to confirm it was well healing.
Plaster? We more often use water activated fiberglass these days. Less heat as it cures, sets quicker.
Very likely she would have been put in a walking boot.
Advil = Motrin = ibuprofen. Each pill is 200mg, so three were a good choice, four a bit better. Redose after six hours if the pain has returned.

Loved the story - but just as an aside, aspirin actually prevents liver damage. Acetameniphen (Tylenol) is what is traditionally known as dangerous for the liver, and non-aspirin NSAIDs such as ibuprofen have recently been linked to stroke/heart attack risk increase. lol I know this has nothing to do with erotica, and your story is fantastic - but if it were me writing this? (and I do write a ton - I'm actually a professional author), I would have had Jack (the athlete) share his prescription pain killers with his victim, since he's most likely on them (athletes are always getting hurt) and since opiate prescriptions, added Tylenol not withstanding, are the only things that don't increase the risk of liver damage and heart attack/stroke. Plus... let's be honest. They're also the only medications that actually work. And also - it's the very least Jack owes him. ;)

I like your story. Your caveat about discontinuities at the top was way too understated, they were jarring, but I get it. I've been there myself, but please remember to come back and clean up later, you're going to throw a lot of people off.
OK, big problem: Never, ever, ever take Advil and Tylenol together! Ever! Tylenol is Acetaminophen, it's a blood thinner. Advil is Ibuprofen, it's an anti-inflammatory that will also irritate your stomach lining. So between the two, you'll end up with a bleeding ulcer. I think the standard recommendation is to separate them by at least twelve hours, though I just stick to one. So unless you're TRYING to mess Hayley up even worse than she already is (bruised, battered, hung over), PLEASE stick to one or the other.
PS: Yes, this is a pet peeve. Yes, I've personally had a problem with both drugs. Google it if you don't believe me.

When you refer to lifelong I think some more explanation is due. Did you lack the sexual cravings that almost all adolescents have? Did you masturbate before having sexual contact with another person? Not intercourse per se, but kissing, fondling..etc? Have you ever experienced an orgasm, with or without a partner? Does your vagina lubricate when you are exposed to sexual situations? As far as males with low libidos, often that's a result of another underlying physical, or mental anomaly. Please don't scare people, exogenous testosterone creams carry little risk. Most that find themselves in need of these creams are not under forty years of age, and usually older than than that. While I wouldn't recommend them to anyone who has had prostate cancer the risk is minimal. Taking over the counter medications such as Advil, Motrin, which are both ibuprofen, can cause severe kidney damage in large amounts, yet are safe minus pre-existing kidney problems, when taken properly they provide effective and safe relief from pain. The same can be said for exogenous or injected testosterone and estrogen provided it is used correctly. HSDS can, and does come with life changing effects. It has the ability to prevent and kill marriages. So if pharmocological therapy can eliminate or reduce the aforementioned effects, it should be understood that it remains a viable and safe option in the treatment HSDS.

Telling others that you were abducted is a quick way to be dismissed as crazy. Giving blood regularly would be one way to end up in a laboratory: blood donations are not truly anonymous in the United States as they can be tracked via testing. Hurting your girlfriend during cunnilingus means your techniques suck, it has nothing to do with tongue length. The same with sex, unless you have a micropenis, because the G Spot is less than 2-3 inches deep in virtually all women and their vaginal depth (opening to cervix) is less than 5-8 inches.
If the aliens had trained him or given his cock(s) some sort of auto-adjustment and autopilot mechanism to optimize length and girth, and target the G spot and cervical opening for any woman, then it makes more sense for him to suddenly become a sex god. Adjusting his testosterone and pheromone production, as well as the biochemistry of his semen to have much higher anti-depressant/mood-elevating properties would have a greater effect than any size increase would. (It's true, semen can have antidepressant and mood-elevating properties for women, but it's mostly through vaginal and anal absorption, since oral absorption rates are extremely low and the stomach would break down the prostaglandins and hormones.)
It is true to some degree that bitterness is often a reflection of diet, but the increase of sweetness is actually a reflection of blood serum sugar levels. Avoiding bitter vegetables and too much meat can improve semen taste quality, but being in good health, eating a healthy diet, and avoiding seminal and urinary tract infections through good hygiene would do more to improve semen quality than eating pineapple could. I shouldn't even need to point out the miniature pineapple nonsense. You could have just said that they adjusted his semen quality to be much more appealing and beneficial to women and that would have covered it all.

God damn give it a rest. Repeating the same fucking things over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over again!!! STOP!!!!!
