After a long night, my girlfriend and I were exhausted. We had sex, but we were both so tired that neither of us could cum. We decided to take a break on the balcony. My balcony is upstairs and covered with plants, so it's very private. There's really only one neighbor to our right that might be able to see us if he peered through the plants, but I doubt he ever would. We grabbed our robes and proceeded outside.
We sat in our chairs facing one another in our robes. I let my robe slip open to give her a little tease of my cock. She opened up the top part of her robe - exposing her perky nipples to me. I opened up my whole robe and started rubbing my chest and stomach. I was pinching a nipple with one hand while the other hand slowly made its way down to my cock. Meanwhile, she completely opened her robe and started rubbing and pinching her nipples.
The sight of her rubbing her boobs like that turned me on instantly. I started to slowly caress the shaft of my cock up and down very gently. She matched my every move and began rubbing her clit with one hand while cupping her breast in the other.
Our pace increased. Seeing my girlfriend over there fingering her own pussy while she watched me stroke my cock was a huge turn on. And when she started moaning, I couldn't wait any longer. A long stream of cum splattered over my chest and stomach as I convulsed in my chair. I used my cum to lubricate my cock and continued caressing it while I watched her feverishly rubbing her pussy and fingering herself. About a minute later, she climaxed with a loud moan.
We laid back in our chairs totally spent, relaxed, and satisfied. We chuckled about how the neighbors probably could have heard what we were doing out there on the balcony and went back to bed.
