My sister in law owes my wife a ton of money and she’s been working it off around the house.

Little things like the dishes, vacuuming (we have a dog, so this is a frequent thing) cleaning our storage closet, etc.

But what really got me was this morning. She was mowing the lawn. Which first off, is sexy as fuck. I love when a women does a man's job. Especially when she's in a white tank top and short shorts.

I've never looked at her like this. But it's hard not to. I was walking about the kitchen window and instinctively looked out. She was glistening with sweat. I felt bad at first. I wanted to come out and tell her she didn't have to do that. She is so sweet. But then my animal brain noticed the slight bumps of a nipples wanting to break free.

I took a sip of coffee and watched her mow my lawn. The whole scenario caught up to me. She owed us money. She owed me money. And she was sweating for it.

I felt myself getting hard. I leaned against the counter to feel something against it.

She was mowing away from me now. Her juicy ass swaying from side to side.

I was slowly letting my dick slide against the edge of the counter. Fully erect. She was coming back my way now. Her pink sunglasses made her look so sweaty. Her blond hair pulled back in a pony tail.

As I saw her bound breasts bouncing and I absentmindedly reached down with my left hand to squeeze my cock hard.

And that's when she waved at me.

I nearly dropped my coffee cup. It's a window, you moron, it goes both ways.

She turned off the mower and came in.

Fuck.

The shock made me lost an inch or two, but I was still pitching a tent when she came inside.

With a smile that could sink the titanic she said hi. Because of the way th kitchen is setup there was still a counter between us. She couldn't see what she did to me.

She was asking how I was doing. We made small talk. I made her laugh. And then she asked about the keys to the shed and I said they were right in this drawer. Not thinking she would come around to check.

I opened the drawer quickly. Covering my bulge beneath.

If my wife would've walked in from the other side of the room, it would've looked like her sister wasn't digging in a drawer, but in my pants. Stroking me like it was her job.

The idea made my dick Twitch underneath the open drawer.

And then I could smell her. Like flowers and the perfect kind of body odor. Pheromones have to be real because it almost awakened the beast in me. I wanted to push her down against the counter top and …

That's when she closed the drawer. Saw my fully erect bulge.

"Oh!" She said.

"Uh…"

"I'm sorry , I …" she stammered. Looked away.

But then looked back for a second.

"I'm on new medication it uh…"

"I totally get it," she said. "I better get back to work."

Her face was a little red. And she smiled and I could almost hear a giggle?

And I've been hiding in my man cave in the basement ever since.
