Holes or No Holes

Adm Note: I post a few pictures that can not be posted here almost every day to ourbottomsburn.bdsmlr.com. New logins to bdsmlr have been closed for months, and I have no idea if they will ever allow new registrations again. However, a few of the lastest posts will be displayed.

It was nice to be able to post any content to the ourbottomsburn website. But what turned out to be a $200 a month cost to me was a little much.

Written by a loyal reader:

Since I am not an expert at Physics, I went to the expert. The answer below is from Artificial Intelligence. I phrased the question to ensure no Kink filters were activated. 

 

 Question Posed:

 Regarding the physics of a flat body such as a wooden plank striking a surface, does the plank strike the surface harder if there are air relief holes in the plank?  

The Answer returned:

At the speed of a normal human arm swing (roughly 10–20 m/s for a fast strike), the presence of air relief holes in the plank would make a small but potentially noticeable difference in impact force, though not dramatic. Here’s why:

Factors Affecting Impact Force

1. Air Cushioning Effect (Minimal at Human Swing Speeds)

   • Without holes: When the plank gets very close to the surface, air is momentarily trapped and compressed, which slightly reduces the impact force.
   • With holes: The holes allow air to escape more easily, reducing this slight cushioning effect, leading to a marginally harder impact.

2. Aerodynamic Drag (Negligible at This Speed)

   • At 10–20 m/s, air resistance is present but not a dominant force.
   • If the plank were moving at very high speeds (like 100+ m/s), reducing drag via holes would matter more.
   • At arm-speed velocities, drag reduction from holes would have an insignificant effect on the plank’s speed before impact.

3. Mass and Structural Integrity (More Important Than Air Resistance)

   • Adding holes reduces the mass of the plank. If mass is reduced significantly, momentum (p=mv) decreases, which could actually reduce impact force.
   • If the structure weakens due to too many holes, the plank could flex or deform, dissipating some impact energy.

Final Verdict

• Small Holes (Properly Spaced): Might allow slightly harder impact by reducing air cushioning.
• Large or Many Holes: Could weaken the plank and reduce impact force.
• At Human Speeds: The difference is minor, but in extreme cases (large surface area and very fast swings), the effect might be perceptible.

So, while air relief holes might slightly increase impact efficiency, their effect at human arm speeds is relatively small compared to the plank’s weight, stiffness, and how it's swung.

I made several paddles as gifts, like the one on the second from the right. I used  Popular wood which is "light". I blindfolded my three "nieces" and paddled them several times with and without holes. It was, at best, a coin toss as to which paddle they thought I was using.

A human might detect a difference for a long wide frat-style paddle.

Based on the evidence presented, I claim holes in paddles make no discernible difference.

A Dancers Ass

Over the years, we have spent months near the little town of Silverton in Colorado. It was a principal mining town in the late 1880s. Left are hundreds of miles of Jeep trails that allow you to tour the colorful San Juan Mountains. The main street in town is paved. The other four are not.

An excursion train follows the Animas River from Durango to the town daily to deposit a hundred tourists for lunch in the several restaurants and shops.

There is one bar that features a drink that I have never been able to recall the name of.  The favor of the drink comes from a large glass bottle above the bar. Objects float in bottle. It's named something like Black Death.

One year, our waitress was tall, thin and had an ass that could crack walnuts. I noticed this feature before she served my first Black Death.

All the buildings were constructed in the 1800s. This one had a cellar accessed by something too steep to be stairs but not quite a ladder. There was a door in the floor to access the cellar.

Our waitress bounded with the precision and grace of a mountain goat up and down the stairs. Bong, bong, bong. Her tight dress hugging her ass.

I had to chat her up. It was a summer job for her. She was a ballet dancer.

I ordered another drink.

Damn, not one picture of the dancers ass.

This one is just as tight.

Her Slipper on HIs Thigh

This is my Valentine post for the traditionalists. The Princess is spanked.

Now to my post.

I was going through my stash of F/M spanking videos this morning. I tripped over one that I downloaded in 2011. I do not recall it.

It's home made. Very poor video quality. I have never been a fan of the slipper. I never thought they packed enough punch to warrant experimenting with one. [I may have made a mistake]  She uses her bedroom slipper on him - pink fluffy top with a flexible plastic sole.

You know both of us like to have our thighs spanked. She not only uses her slipper on his bottom, but devotes several minutes to slapping the front of his thighs with it. You can tell that it really gets his attention with his yelps and a rigid member.

What makes this video for me is that she smiles through out. She knows she is putting sting in his legs and she keeps on smiling. A good spanker. None of that stern, strict BS.

No stills from the video or from Bacall slapping my thighs. This is the best I can do.

Her legs will be stinging for some time

The Brits version of a slipper is a gym shoe. Much more substantial. A sandal with a wood sole is whole nother thing. It has almost as much sting as a hairbrush and so handy in the warm months. Sand, sundress, sandals and hot bottoms.

I remember from grade school that girls could pass notes and whisper without being caught. They continue as adults. How many flashes have you missed when it happened right next to you?

THIS is the cutest girl in the world

I know this is from a pro shoot. [I don't care who they are] I like that they are both well dressed. No ink, metal or unnatural hair color. Based on the watermark, she will be the one feeling the wood. She seems pleased with the choice.

This 1954 picture of Grace Kelly in Rear Window defined female beauty for me my whole life.  Pearls and high heels.

If Grace Kelly assumed the position, it would look like this.

You have something better to do today?

50's room, 90's ass and new straps

Before I die, I would like to know why girls cover their mouths. Feigning embarrassment?

Kelly Payne lays her strap on hard. And dresses for her role.

The famous Goosenecks in Arizona. This place is covered in people from dawn to dark. So this photo is fake.

When you can't find the stairway to heaven, but hope to make the cut anyway!

Spank or be Spanked

 

I have posted this before. All I see is the gal on the left. I am enchanted by her expression and the shape of her boobs.

Waiting

Perhaps her wait is almost over
