His Keyholder's Grip: A MM BDSM Chastity Straight to Gay Erotica Story

by M. Syrinx

Go ahead and move against my grip, you have my permission. I like feeling you strain for what you know you’re not allowed.

Chris knows he’s a demanding submissive. And that’s even before his roommate Aaron has him endure a long maintenance edge and tells him to open up for a deep training that has Chris swallowing everything he shouldn’t be craving.

It’s so hard to be patient and wait for permission. But with his insanely good-looking roommate as his keyholder, Chris wants to be good. He really tries.

Then something from his "straight" past catches Chris off-guard, and suddenly he's making demands of Aaron that he knows will get him in trouble.

But it's not until Aaron gets out the chains, the spiked chastity, and tells him to present for his punishment that Chris begins to understand that he’s in for the kind of pain that will have him shivering in masochistic pleasure and begging Aaron to teach him his lesson the hard way.

This 27,000-word consensual BDSM erotic story is the sequel to 'His Keyholder's Rules.' It includes bondage, edging, orgasm denial, sadism, masochism, pain play, chastity, humiliation, cropping (a LOT of cropping), CBT, impact play on very specific areas of human male anatomy, and in-depth submission training.

This was a great read with all the diabolical, delicious smuttiness I love about M Syrinx's books. It was longer than I'd expected which was awesome, and I look forward to book 3. The ending threw me because I thought (aka hoped lol) for sure Chris was going to end up earning a month long punishment but he got lucky with just a week 😂😂.

You know what’s just fucking nice? That these are always quick, dirty-as-fuck smut to read in an hour or so, but they’re—not to me (now) because I already know, but still—surprisingly deep. The characters have layers and the way they play off of each other is really fucking good. They masterfully prove that you can have full-out MegaKink and still make it more. Things don’t have to be one or the other.

4.5/5. That’s what’s just fucking nice. It’s absolutely swell. This was spicy-spicy, and I was here for their continuing journey.

Just finished this one and thought I should definitely leave a review🙂‍↕️
I’ve read a few of M. Syrinx’s books and this series is not just for smut(ahhh), but has surprisingly deep main characters.
If you are ok with chastity, bondage, edging, bratty and needy sub, mean and sweet dom(did I miss something?🫦), then go for it!
Read #1 first though.

I wish this had been more obviously a sequel because I felt like I was missing information and I was! Still an enjoyable erotica with a chastity theme.

I liked the characters, so I'm reading the series. Enjoyable escapism.
