I don't quite know where to begin. My name is Mary and I'm a junior in college. To make a little extra money I got a gig babysitting for a nice couple. Their son is polite and well behaved and we have a lot of fun. And once he's in bed, I've got the house to myself until they come home. And the money is pretty darned good for what's a pretty easy job.

I mainly deal with the Mr. - he texts me to ask if I'm available, usually a couple days in advance. They go out at least once a week, but on random nights. Still, it used to be no big deal, since I didn't really have a whole lot of a social life at the time.

But then I met Tom. He's on the lacrosse team and in pre-law. He's smart and funny and... well... he knows just how to turn my guts inside out, if you know what I mean.

Of course, Tom knows about my gig and I've told him that I've never turned them down and he's been fine with it.

I guess where the story really starts was the last time I sat for them. After I put the kid to bed I got on my phone and started texting Tom. Well, that sort of turned into dirty talk and that sort of got me going. He tried to invite himself over, and of course I said "No!" At least... I did at first... But he kept talking about how much he wanted to fuck me and... well... I broke down and said, "Fine, but it's got to be quick before they get home."

He made it over in record time, and, well, he bent me over their couch and we both came. We cuddled on the couch for a little bit, and then I told him we were gonna get caught if he didn't high-tail it and sort of playfully kicked him out."

I thought it was the perfect crime.

The next day, the Mr. texted me that he needed to talk to me and wanted me over Saturday afternoon. I read that text and a big ball of fear knotted up in my stomach. He had never done anything like that before. Did he know? I started typing a huge confession and apology... but then stopped and erased it. This could be nothing. I started to reply again, this time saying that I'd be there.

The next couple of days I didn't really think much more about it - I had classes and homework and all the rest. I didn't get to see Tom. Looking back, that was probably for the best. Saturday morning came and I had nothing on the calendar except that one appointment, and that brought the entire thing back into focus. Was this about having Tom over? What else could it be if it wasn't? There was no way to know other than to go and find out.

I got there on time and rang the bell. He welcomed me in and brought me into his study and had me sit down.

"Mary, this is pretty serious. I'm not going to beat around the bush. Watch this."

He turned to his desk and clicked a key on his computer. A video opened up. It was a view of their living room I'd never seen before. And I walked into view with Tom behind me. As soon as I saw it my entire body turned cold and I felt like a trapped animal. I wanted nothing more than to crawl into a tiny hole and hide.

When he spoke, his voice was more sad than angry, "I'm deeply, deeply disappointed in you, Mary. Do you honestly think it was acceptable to bring a stranger into our house while we were gone?"

I looked down at the floor. My voice didn't work properly when I replied, "No."

"What's that, Mary? I didn't hear you."

I looked back up at him, my eyes misty, and I choked out "No, sir."

What he said next... I've never felt so guilty about anything in my life.

"What am I supposed to do about this, Mary? We can't trust you now, can we? Our son really likes his evenings with you and we really were at ease leaving him with you. And now we have to throw all that away?"

It wasn't losing out on the extra money. It wasn't even so much that I disappointed them. It was that I was potentially going to disappoint their son. I couldn't just couldn't have that happen.

"Oh please, give me another chance. I've been going with Tom for a while now, and I... well... I wanted to..."

He shot back, "You wanted him to fuck you on our couch?"

I was devastated. I realized what I had really done, and how stupid it was.

He sighed, "Mary, I don't want to fire you. But if you're going to keep sitting for us, there are going to be consequences."

I looked back up at him. A thousand emotions flew around in my brain at the same time. There was hope - he wasn't immediately firing me. Maybe this wasn't going to be the end. But consequences? That brought fear to the forefront.

"I'm going to give you a no-nonsense, bare-bottom spanking. If you accept that, then we'll put this whole messy business behind us. If not, then it's goodbye."

Oh my God.

I tried to process it. I had never been spanked, but I had heard from school-friends about it and it sounded painful and embarrassing, and that filled me up with fear and foreboding. But what choice did I have? Moreover, I felt like I deserved it. And in the end, that's what made my mind up. I would do it because if the situation were reversed, I'd want to punish me for what I did too. I swallowed hard and nodded my head.

His voice was firm and commanding. "Stand up, Mary."

I slowly stood up. He moved towards and past me, and I stepped aside to make way. He sat down in the chair, and I turned to face him. He reached out to my waist and roughly unsnapped and unzipped my pants and started to work them down my hips. My knees felt wobbly and I shivered. I couldn't remember ever being so embarrassed. It was all I could do to use my hands to hide my crotch from him while I felt the heat in my cheeks and forehead.

Next, he grabbed my elbow and dragged me over to his right side and then over his lap. I fell gracelessly across him and grabbed at the legs of the chair to steady myself. My field of view was limited to the floor in front of me, and I felt his left arm firmly hold me by the waist and his right hand land on top of my bottom over my panties. In a flash, the embarrassment was pushed aside, and raw naked fear was front and center.

"This is going to hurt, Mary. It's going to hurt quite a bit. You can stop any time and walk away, but if you're really sorry for what you did and want to stay on with us, you'll take your punishment like a good girl. Now, are you ready?"

Now the fear was joined by guilt, and I heard my own voice give its assent, "Yes, sir."

The first swat was more of a surprise than anything. I heard the sound of it and felt it, and my voice made a noise, but what I remember the most was the heat that followed. And then the next one came on the opposite cheek and the burning fire started to build. I tried to move, but he held me firmly down. I kicked my legs in a futile attempt to do something, anything, to calm the fire he was stoking in my bottom.

After far too many swats to count, he paused for a moment, and I felt his hand tugging at the waistband of my panties as he exposed my bare bottom, and the embarrassment welled back up again I felt like every part of my body was on display now, and I started to cry in earnest.

He started spanking again, spreading the fire around every part of my bottom. My entire world was reduced to the steady rhythm of his hand, the fire and heat and the crying. And then there were a dozen slower and harder ones right where it hurt the most, and then he ordered me to stand up.

I got back up on my shaky legs, and all I could do was rub my bottom with my hands and move my feet to try and soothe the burning fire while I just cried my eyes out. When I finally came to my senses, the first thing I noticed was he was still sitting in the chair watching me, seemingly waiting for me to calm down.

Then he stood up and said, "We're not quite done yet, Mary. You're going to take a dozen from my belt, and then we'll be finished."

I was crestfallen, but at least there was a light at the end of the tunnel. He stepped to the side and gestured at the chair. "Stand here, Mary, and put your elbows on the seat of the chair."

I stepped to where he wanted me and bent over and rested my forearms on the seat of the chair. Once again, my field of view was limited to the back of the chair directly in front of me.

"Move your feet a little bit further apart."

I walked them outward as far as the pants around my knees would allow. I heard a little metallic tinkle behind me and a soft swishing noise as he pulled the belt out of his pants. A second or two went by, and I felt the belt tap my bottom, and it made me flinch.

And then there was nothing for just the briefest moment. And then there was an intense line of fire across the center of my entire ass at the same time as a loud crack filled the air. My mouth let loose with a loud wail before my mind was even aware why. When my lungs ran out of air, I just started crying harder than ever. The next line of fire arrived and the next and the next, and once again my entire universe was reduced to the crying and the fire. I had no idea whether he gave me a dozen or a thousand before he stopped.

"Alright, Mary. Your punishment is complete."

Relief.

That was the only thing in my mind: relief that it was over and that I had paid for my crime. The relief flooded over into gratitude, and I ran to him and threw my arms around him. In the cold light of day, the gratitude makes no sense at all. Was I grateful that he allowed me to atone for my sins by striping my ass with his belt? Was I grateful that he stopped? But none of that mattered. He held me as I cried on his chest and just kept repeating, "I'm sorry, I'm sorry..."

He returned my hug gently and in a soft voice answered, "It's ok, Mary. You took your punishment and it's all over. It'll be like this never happened. You're never going to bring anyone into our house again without permission, are you?"

I blurted out, "Oh no, sir, no, never. I promise!"

"Good girl. Now, put yourself back together again, and you can wash your face in our bathroom if you like."

I blushed as I suddenly realized I was naked from the waist down in front of my employer. I reached down and pulled my panties up quickly to restore my modesty, then repeated the operation far more gingerly with my pants. The heat in my bottom flared up, trapped in by my clothing.

I wiped the last tears from my face and turned and walked out to the bathroom. There I dabbed some water on my eyes and grabbed some toilet paper to blow my nose. I looked in the mirror. I was still me, despite my eyes being a little bit red. I suddenly wanted to see how bad the damage was, so I lowered my pants and panties and looked at myself turned around in the mirror. My entire ass was flaming red, with a whole bunch of darker red welts that must have been left by his belt. I moved my hands back and felt the heat that was still flooding out.

And then... out of nowhere I felt a little twitch deep in my groin. I squeezed my thighs together and shook my head clear.

I pulled my pants and panties back on and went back out into the hall. He was standing there, so I gave him a hug and reached up on my tiptoes to kiss him on the cheek.

He smiled. "Promise me you'll be a good girl from now on, Mary."

I smiled and felt a little flush in my cheeks. "Yes, sir."

I walked out the door and over to my bicycle, which I had left leaning by the front door.

Well, that's not an option today, is it?

I grabbed it by the handlebars and started pushing it back towards my apartment.

As I walked, I started thinking about Tom. He's not going to be able to smack my ass next time he fucks me, I guess.

But then my mind conjured a different thought. An image of me, naked over Tom's knee while he spanked me. Maybe not quite so hard... Maybe...
