I’d had quite a hard day at the office running around and was pleased to be home. I’d changed out of my work clothes and was wearing my denim skirt with a plain white T shirt and no bra as I thought I would be hanging around at home. I went into the kitchen and started unloading the dishwasher. My son’s friend, Brad who was at college with him was sitting on the sofa in the kitchen drinking a glass of water.

“Hi Brad,” I said, “I didn’t know you were here.”

“Oh, John’s gone to work and I’m just waiting for my sister to pick up the phone so she can come and get me,” he said.

Brad was eighteen at the time and had known my son for a few years so I was pretty comfortable with him being around. He had turned into a handsome young man in the last couple of years with a reputation for being a little uncomfortable around girls.

As I kept bending down to pull crockery from the dishwasher I noticed Brad looking sideways at my feet as they flexed off the ground. I was barefoot as I often am around the house.

I do have really great feet. size eight and slim but not narrow and I am used to them being the object of affection as Scott likes them a lot. So I thought, “let’s see if that’s really what he’s looking at.” I moved across to the other side of the kitchen to near where Brad was seated, sat on a chair and picked my foot up to look at the sole, saying, “I think I stood on something... oh well, may be not.”

Brad’s eyes almost jumped out of his head as he got a full view of my sole and I could feel my nipples start to harden slightly under my T shirt.

Even better still, I could see from in his shorts that he was enjoying it, not much, just a small movement. I thought, “what the heck, let’s see if we can make this interesting.”

“Brad, would you like me to give you a lift home?”

“If it’s not too much trouble that would be great…. my sister seems to have switched her phone off.”

“Sure, no problem, let me just put this in the garage first,” and I grabbed the nearest thing to me which was a pile of newspapers. As I walked into the garage I threw the newspapers in a pile and got on to my hands and knees to look for a small stone or a piece of gravel. Found one!

Fortunately I'd had much practice, so it was the work of a moment to take off the dust cap of my rear passenger side tyre valve, put the stone in it and screw it on just tight enough for some air to start coming out. As I heard the rush of air and smelt the rubbery odour of the tyre air I started to get that warm feeling deep inside me that usually leads to a great evening.

“Are you ready? Meet me out the front,” I called to Brad and jumped in the car, hit the garage door remote and reversed onto the drive.

He came out the front door and jumped into the car next to me.

As we drove off I could start to feel my Focus just gently pulling to the right and I made sure that Brad had a great view of my feet working the pedals. He moved his hands onto his lap and left them there.

As our deflating tyre started to pull the car a bit more I said to Brad, “I think there may be something wrong with the car. It seems to pull a bit,” and as I let go of the steering wheel the car pulled off towards the curb.

As the tyre got to the stage where it was starting to make the really sexy rumbly noise that is where you can see it outside the car clearly and feel it inside the car, I thought let’s make this spicier, so as we drew up to stop light I took off my flipflop put my foot up on my leg and said to Brad, “can you rub my sole I’m sure I have something stuck on there.”

He carefully left one hand on his lap and gently caressed the bottom of my foot. My nipples went hard against my T shirt and I could see that one hand wasn’t going to cover the bulge in Brad’s shorts for long.

“No, it all feels good,” he blushed and added quickly, “I mean I can’t see anything in your foot!” As we drove off I felt the car start to wobble on the flattening tyre and my D cup tits start to bobble in my T shirt.

“I think we have a flat,” I said, “let’s stop and look.”

I pulled over and got out of the car as Brad did the same trying to cover the mound in his shorts. And yes, it was definitely nearly flat. I put my foot on it and pressed and Brad almost passed out watching my bare foot on the hissing tyre.

I squatted down by the tyre and made sure Brad could see my feet lifted off my flip flops right next to wear he was standing.

“Hey, look at this," I said, and as he bent down with me I pulled my T shirt down slightly so one of my breasts just popped out the top. “Touch my breast, touch my feet,” I said.

"I can’t,” Brad said quietly, “I’ll have an accident.”

“That’s the idea,” I said and picked his hand up and moved it caressingly around my heel.

“But what about the flat tyre,” he said breathlessly," do we change it or what?”

“No,” I said, “let’s leave it like this and go for a drive, I couldn’t be bothered to change it today!”

When we got back in the car the air had all gone from the tyre and it thump thump thumped its way down the road as I eased car back onto the road. As it was a nice quiet road, I gave Brad my foot to hold and gently eased him out of his shorts with the flat gently thrumming away underneath us it only took moments for Brad to come repeatedly.
