When my partner and I lived in a flat a few years ago, a new neighbour moved in next door. She was hot! She taught paddle board lessons at the beach and her body definitely showed the results of that.

We introduced ourselves to her and would say hello as we would pass by. She was nice and always smiling.

Over the next couple of weeks I began to notice she would always stick to herself. Being as hot and fit as she was I expected her to have a partner of her own or at least a fling here and there. But, none.

My partner and I would have sex 5-6 times per week. Maybe once or twice in the week but we definitely made up for lost time on Saturdays and Sundays. Our bedroom shared a wall with our hot neighbour. We weren't loud and the insulation between our units was decent as we couldn't really hear anyone else other than furniture moving but our bed would sometimes bang against wall, in a tell tale rhythm. And our bodies would slap together making it sound like a round of applause in our room which mixed in with my partner moaning, it was obvious what we were doing if you put your ear to the wall. We weren't trying to put on a show or be heard but some this are inevitable when living so closely.

Eventually, during one of our weekend sessions during a bathroom break, I heard a faint buzzing noise. I put my ear to the wall and it was louder, but I could also hear my neighbour moaning. She was masturbating, using a vibrator, I thought!

The thought of this turned me on as I thought she was listening to us a few minutes earlier. I was hard as a rock and pounced on my partner upon my return to continue our weekend fuck fest. I made extra effort to moan a little louder myself and smack my girl's ass more frequently as well.

I noticed this carried on over the remainder of us sharing a wall nearly every weekend. We'd fuck, and then I'd hear vibrations. It was such a turn on to know someone so hot was getting off to the sound of us fucking.

We'd often bump into our neighbour in the parking lot passing by and she'd be a friendly as ever not giving away any signs.

I wonder if she knew I knew she was cumming while we were cumming? Still didn't see any partner of her own the entire time we lived there so i guess she was satisfied with our sex life.
