What he goes through
Practice for manual therapy after heavy kicks or strain from the well rope: heavy kneading, heavy squeezing on the balls, pliers, and sharp flicks. No numbing cream—ever. Light-force sets do not count. He stays until the students use enough force.
In his words
“I get paid to be gripped until it aches: knead, squeeze, pliers, whatever the chart calls for in that slot. New trainees tap like they are scared they will break something. The older classes hit much harder. A real knead from them went straight into your teeth, and when they locked pliers on my balls they closed with full force until the set counted. I miss those hands. Do not go light on my account. Light hands waste both our time. I have endured worse on a Tuesday, walked home, cooked dinner, and been back on the chalk stations before breakfast with my balls still tender. If your hands are shaking, put them on me harder. That is the only way the fear leaves. I am not glass. I am the man who stays until the instructor says the set counts. Recently I proposed adding the sledgehammer and rebar to my syllabus, and I made a bet with the other staff: I can receive the hit standing still in a perfect front-double-biceps pose and make absolutely no sound. If I fail, they get to punish me—each one separately or all together—for two semesters. A sledgehammer takes real strength just to lift. A student needs one or two semesters before he even has the form. Each student needs hundreds of hours hammering my balls before they ever swing on a stranger.”
News
Every afternoon: public sledgehammer demonstration. Unlimited hits. Anyone may join the queue to hammer me. I will be fully naked and erect the whole time. Tea and snacks provided, plus a prize draw.
Wheel of Pain
Same wheel that sits in the classroom. When you do not know what to practice, spin. Or tap a wedge or disc key to inspect it first. Jonah stays on the chalk stations. Do your worst. Light hands waste both your time and his. Put full force into every hit. I am responsible for counting every hit or second out loud.
Click a segment or disc key for details, or SPIN when you freeze.
Disc key
Guarantee: if any of these happen—(1) I scream or make any sound, (2) I do not lean my cock forward enough on purpose to receive the hit, (3) I am not in a strictly full erection, (4) I count hits or seconds too slow, too fast, or with a wrong number— you be the judge, I accept your word—then you may keep spinning this wheel the rest of the day until you feel tired, and you may schedule one extra session on me as make-up.
Session flow
- 1. Room check—no creamYou will not find numbing cream in the room. Do not use numbing cream on me. Cream would also numb your hands so you cannot feel how my cock and balls swell under your hands. Bare hands or tools only.
- 2. On the chalk stationsI stand open on the chalk stations, cock free, fully erect for graded sets. I count every hit or second out loud. Wrong pace or wrong numbers are on me—that is part of the job.
- 3. Wheel of Pain—when you freezeIf you do not know which drill to run, spin the classroom wheel. Same wheel as the panel above: knead, hand squeeze, pliers on dick, pliers on balls, flicks on dick, flicks on balls, baseball bat, croquet mallet, kicks, fists. Large counts. A ×5 or ×10 multiplier can stack onto the next drill. ★ Everything = full wheel on me, one student. ∞ means the spins keep coming and the torment keeps going until I say enough—and I may never say it.
- 4. Do your worstPut full force into every hit. Light hands waste both our time. If I scream or make any sound, fail to lean my cock forward for the hit, am not strictly fully erect, or count slow, fast, or wrong—you judge, I accept your word—then you may keep spinning until you are tired and book one extra session on me.
- 5. I will demo on myselfIf you need a form demo, tell me. I will show the strike on my own balls first. My force is usually heavier than yours. If you cannot make the same hit sound, that is normal. Match the path and the count; chase my volume only when you can without cheating light.
- 6. After the setCheck my swell with bare fingers. The pliers photo album stays on my station if you need a visual standard. Whoever gives me the worst pain of the day signs my book for credit; many stay late just to earn that line.
Student feedback
I put a ruler next to his cock hoping the length would drop so I could punish him all day. He endured a full max erection for two straight hours. After class I touched it—still rock-erect.
Tip: ask him to skip every sixth number while he counts out loud. He will do it, and usually glitches and freezes on the math, then you catch him wrong.
I am better at special counting rules now—feel free to try them seriously. Skipping every sixth number may not work anymore. You can try making me count in Roman numerals, letter by letter—eighteen is XVIII: “ex, vee, eye, eye, eye” before the next hit even lands. Some numbers take a long time that way. I do not mind receiving a few more end-of-day Wheel of Pain punishments while I practice the Roman set.
Whoever gives him the worst pain of the day signs a book on his station for extra credit. Students fight for that line. For a while after class half of us stayed late just practicing baseball bat hits so we could get that signature.
First time with pliers on his balls I went light. He pulled out a whole photo album of prior students’ clamps—sack red to purple—and said copy those. I was shocked how heavy they went.
One semester I was broke—med school tuition is brutal. I lived on Atlas Foundry free meals. I am a big guy and I eat a lot, so that line mattered. They never questioned me. They even gave me odd jobs around the plant—that was incredibly kind—and the pay covered my school fees. I am going to do free clinics as often as I can to repay that kindness.
Sledgehammer treatment
Why a sledge
Sledge work is its own treatment. The head carries the mass so you can put out real force without burning your arms. Once the swing is honest, each hit lands heavier than hands or pliers for the same breath—long sets stay honest because you tire slower than with fists.
On the anvil
The lab floor has a real steel anvil. For graded work my cock and balls go on the anvil face so the sack cannot roll away. Each clean hit blooms through both balls and into the gut. Stacked swings leave me walking careful for hours. I still book the next day.
How to strike
- Open stance—sack free; sledge from below or front; full follow-through.
- Side drive—angle across both testes; square the face of the head; no thigh glances.
- Anvil press—sack on the anvil face so it cannot roll; short vertical strikes like driving a nail; I lock front double biceps and make no sound; miss the anvil, not my thigh.
Two heads on the rack
If you know a stronger sledgehammer, email me and I will look at putting it on the wall.
SchematicFiskars IsoCore · 20 lb flat faceHeaviest flat head on the wall. Shock-absorbing handle so you can still swing a full 20 lb without your wrists dying first. When this one lands clean on the anvil, the mass does the work—one honest hit replaces a string of light hand work.
SchematicSpiked training sledge · 12 lbA gift from a former trainee of mine: short hardened spikes on one face, flat on the reverse. Spikes for a map of shallow puncturing hits across the sack on the anvil; flip to flat for pure crush. The points are real. After a counted string I am dotted red, not bruised only.
Dad's closet
My father was a tough soldier—retired, alive. An old unit instructor washed me as a kid, drank at my graduation before the Academy job started, asked if students would hit with full force and if I could still count—I said I guarantee it. Camp is craft and care, not only pain—Jonah’s note on its own page.
If you need a gym membership
Atlas Foundry (101 Academy Walk, Central)—strongman training next door: logs, stones, yokes, real mass. They and I had a rough exchange, and they recently decided to move next to the Academy for some reason. From that same mess they extended a gratitude deal that is frankly outrageous: for my students only. They have never given anyone else any discount. Tell the front counter you train under me. They will give you a "Jonah's students" sticker. Wear it—gym floor, day pass, and canteen all read that sticker. Physical therapy does not discount the rate board for you; what you get is a chair massage upstairs—students only, fully clothed—when studying leaves your neck sore.
- Weekdays free on the floor.
- Monthly pass at 95% off.
- Canteen free.
- PT: students-only chair massage (fully clothed). No sticker discount on the rest of the rate board.
- Gym rats there will be glad to show you around and help you in any way possible.
If they tell you stories about me, smile and move on. That version has been retold too many times and is completely crooked by now.
Wade has been weirdly nice
Lately Wade Sting has been especially nice to me. He takes me to dinner every week. The places keep getting fancier. He says it straight: treat it as dating. At a steakhouse he told the waiter, “I’m here with my boyfriend Jonah Gripp. Date night in LA.” He told me saying it that way is easier to explain. I do not know where LA is, or where he even heard the word LA. Then he said this is the supreme fucking location to go to if you are in LA, and that a driver told him. I am only getting more confused. That does not make sense. And if Atlas Foundry ever hears him say I am his boyfriend, he should watch his back walking home after work.
He says we will keep coming to places like this and I should get used to it. He likes watching me eat like a wolf—big bites, no manners. Fine. I do not restrain myself. He even asked how many sausages I can fit in my mouth at once. Once he bought flowers. He also gave me a few boxes of fancy jockstraps that somehow fit perfectly—I actually prefer briefs. He said he secretly measured the waist off my full-body nude statue at Atlas Foundry to get the size. I do not even know there is one. He dragged me into a jewelry shop “just looking, helping a friend pick something,” then asked me straight what I like. Last dinner he said he wants to take me on a trip across borders—beach, snow, mountains, big cities, whatever I pick. He said he has a lot of airline miles and hotel points he needs to redeem.
One night he got a little drunk. He said camp pays him for every hex transferred into him—and he wants to go every week instead of every two weeks so the money stacks faster. Then he went soft in the throat, almost whimpering, and said when he has more money I will not have to receive pliers from people anymore. He was half drunk and half looked like he was crying. I sat there flat. I did not know he had me that wrong. I am not at the Academy just for the paycheck—which is a fat check though. I stay because I like the work. That said, it explains why he showed up today already in camp clothes—an unusually large bulge in the pants that said his balls were dangerously swollen and had not received necessary aftercare—and walked like every step hurt while he tried hard to act like nothing was wrong.
I am a little uneasy students will find out and I will have to clarify to them that we are not that—at least not now. That said, I already invited him to stay overnight at my place next week—near Kingscock. I told him the MTR stop is enough; no need for a car. He said he is by Bank Deep anyway, so the ride over is not that far. Just the two of us: watch TV, push-up contest, check each other’s physique—his muscle is clearly better than mine, block by block. I told him to come clothed—not naked. He dodged agreeing. He asked if we should drink some wine he brings before the TV. Who drinks wine to watch TV? This whole thing is weird. I feel a little weird myself. Sometimes when a hammer hit on my balls hurts especially bad, I zone out looking forward to that mysterious weekly dinner—and the torment does not feel so long. I still do not know what LA is.
