We live in a nice suburb in sunny Barcelona. Apart from the neighboring houses which are mostly shielded by trees, our house is pretty secluded, and only accessible trough our rather noisy gate in the driveway.
I live with my girlfriend, Valerie, and we have a great sexual relationship. The thing is, that I have a much stronger exhibitionist urge than she does, although she'll quickly take me up on a challenge, although it's more to please me, than to satisfy any exhibitionist urge she may have. For example, flashing her breasts at other motorists while we're driving. However, I do get off on the possibility of being seen naked. Of having other people's eyes stroking my naked body and seeing my dick, when I "don't know" they're watching. I often suntan in the nude in our back garden, but that's generally about as exciting as it gets.
However, one Saturday morning, an opportunity presented itself, that had my mind working overtime. I was in the bedroom, rearranging my cupboards, when Valerie's mobile rang in the dining room. It was her mom, Karen, on the line, wanting to return some dishes we'd left at her place when we went over for dinner a few nights ago. I heard Valerie mention to her that she'd be popping in to the office a bit later, but she was welcome to just drop them off at our place whenever she was ready. Valerie's mom had a remote for the gate, because she was around so often. Not that I mind. Although Karen wasn't a 'bombshell', she exuded a strong air of sexiness and confidence. She had large breasts, and fantastic legs, with nice shapely hips and thighs, and at 48, she was very open minded and adventurous, judging from some past conversations we've had around the dinner table. Her open mindedness is precisely what got me thinking of my plan.
Although I would NEVER try anything with her, I knew that she was the type of person that would never be offended if she were to 'accidentally' see someone naked. In fact, she would probably send encouragement, blowing wolf whistles etc. She always carries herself very elegantly, but I knew she was very naughty, and I was going to test my theory, and get a bit of a thrill at the same time.
