Mdd of ibuprofen

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.

I have to agree with the other commenters: this was very cruel.
I read the punishment sequence multiple times to make sure I wasn't missing any redeeming qualities of Joshua, and while I caught some thankfully, I'd still be worried about Beth and their relationship.
Problems with the punishment:
1. He actually hurt her (physically and emotionally) in ways she hasn't been hurt before.
2. He's destroying her psyche by isolating her from friends and confidants. Hannah works for Joshua and Angelique is her wife, and they've both known Joshua and been his friends far longer than they've known Beth. It's not like she can trust them. Meanwhile he's forbidden her from exploring her feelings with anyone else on the ship. It's not like she's going to trust him to explore those feelings, unless she's a masochist (which I got the impression she was not).
3. It's implied he made her friends participate in hurting her. After which he refused to allow her to see them off. (He at least let her say goodbye; the first time I read through, I missed that and was even more upset.)
4. He made her friends participate in her recovery. Hannah and Reggie are her friends not her friends. They are friends and employees of Joshua, but he had them apply more pain (physical and emotional) to Beth.
5. He's depriving her of sleep and emotional recovery. Slaves hate the Slave Trainer for a reason, and it's not because it keeps them awake. Meanwhile, sleep is ESSENTIAL to emotional and physical recovery.
He's not talking to her. He's trying to show that he's putting emotional and romantic distance between himself and Beth, which does no good. It's clear from conversations we aren't privy too that he really does care for and like Beth, and I'm sure there's some not yet revealed deep darkness and/or sadness to Joshua that Angelique, Hannah, and a lot of other people not named Beth know about that will eventually be revealed and redeem him in Beth's eyes, but leaving her on the out is only causing her to doubt herself and her emotions.
In terms of subdrop: I'm more of a dominant than a submissive, and granted I have my own mental health issues with MDD and PTSD already, but as someone who also studies psychology/psychiatry, I'm really worried for Beth. She's been recently hurt physically and emotionally, she's sleep deprived, she's isolated, and she's a psychologist (and in my experience, it's far harder for people to assess their own mental state than it is in others, especially if they're supposed to know what to look for).
Things I wouldn't let her do if I'm Joshua or anyone with half of an emotional brain among the military veterans or friends on the ship:
1. Go anywhere out on the deck without being secured to someone or some aspect of the ship that is physically immobile. The leash doesn't cut it. I mean she needs to be unable to move anywhere without physically pulling someone with her, if she's able to pull at all.
2. Firearms training or obtain access to where the guns and ammo are kept.
3. Have access to any cooking or eating utensils other than spoons, ladels, etc.
4. Let her tell me she's fine until she's actually had a debriefing with someone qualified and not on Joshua's payroll, and even then, psych professionals know how to lie to make themselves seem fine.
As a reader, I'm sure Beth is fine, but Joshua's issues are going to need to be resolved sooner rather than later, and hopefully before the big pirate showdown where I'm sure that people onboard if not Joshua or Beth themselves are going to get hurt.
