We have an apartment in another city for work purposes and since we
haven't met any of our neighbors, we feel a bit more adventurous to do
things like occasionally walk around the apartment naked or sleep with
our blinds open. Our windows overlook a courtyard and most of the view
from the other units is blocked by a large tree, but we can see and be
seen from 3 other apartments across from us (about 100 feet total
distance). We've never seen the blinds open on one and not even sure
it's occupied, and another appears to be a single guy in his 20s or
30s, but he constantly keeps his blinds closed. The third, which
happens to be on the same level directly across from us, is a couple
that we guess to be in their 30s. They're both attractive (at least
have nice bodies) and we've definitely seen each other walking around
in our underwear before.

Last Saturday morning, we were laying in bed with the blinds pulled up
and happened to catch a glimpse of the cute couple in their room. We
couldn't tell what they were doing, but she looked like she maybe had
a towel wrapped around her as if she just came out of the shower. I
got really turned on hoping she'd drop her towel for me to see and
within a few minutes we were both watching with our hands on each
other talking about how hot it would be to swing with them. She was in
and out of the bedroom a few times, but he was on bed and seemed to be
shifting positions like he was looking over at us whenever she would
leave the room.

We were horny as hell fantasizing about them and knowing that at least
he was probably watching, so decided to go for it and pulled the
covers fully off of ourselves as I went down on her. I licked her
pussy while she told me how our neighbor was lying in his bed watching
us as she lay there naked and exposed. I pulled her on top of me
hoping he'd get a nice silhouette view of her tits to get really
turned on. I also wanted a better view of him watching and was still
hoping to see his partner strip the towel so I could see her naked. Or
better yet, for them to reciprocate with a good show for us in return.
Pretty sure he was rubbing his cock at this point, but he was laying
on his side face us and with the way the light was coming into both of
our apartments, I think he had a better view with the morning sun.

When she rolled off of me, I grabbed her hips and flipped her over and
pulled her ass up to me. Knowing he was watching had me too turned on
and I started fucking her hard from behind. Most times, I'll stop
before I get too close the first time to savor the sex a bit more, but
this time, she was moaning hard as I was getting deep inside her, and
I just felt like I needed it right then. I fucked her right to the
edge before I pulled out, but knew it was too late. I grabbed my cock
and came right on the small of her back.

After I finished and collapsed beside her, we laid there for a minute
watching our neighbors shadowy silhouette. He was super still now and
potentially not trying to be obvious or creepy about it. But, Mr.
317C, we hope you were watching, hope you enjoyed it, and would love
to watch you enjoy it next time. Also, if Mrs. 317C is into, feel free
to come knock on our door sometime if you see us laying around bed
naked!
