It all started innocent enough. Just a few years ago and with just an honest mistake. Back then I lived on the beach, with my girlfriend of four years, in a beautiful two story house that my girl's god father had let us stay in for pretty cheap. So while we had this amazing place, we weren't exactly rich, but nor were we poor. We'd been there for about a year at the time, both of us in our mid 20's, loving our room on the second story over looking the ocean, and its beautiful deck that looked down at our own "backyard" which featured little more than a fenced in pool, a hot tub and a sauna, each of which we used constantly. On the other side of the fence was the boardwalk. Then the beach.
One morning my girlfriend Jen had gone out to the beach with her best friend and I'd stayed behind in order to sleep a little longer and eventually head out for a run. That morning I felt particularly lazy though, and decided not to seriously take my time before running anywhere, fumbling through a slow morning routine of waking to the world. After catching up on sports highlights I got up and stood naked in my room listening to my iPod in order to have some good old motivational rock and roll to get me ready for the run. Before I even found my shorts though I took an obligatory stroll to our full length closet mirror, in the small hallway between the doorway and our room, and looked over my naked body. So I stood there as silly as can be with no inhibitions (I was alone, after all), making faces and flexing my muscles to the music, when Jen's best friend rounded the corner wearing just her bikini and stopping only a feet from running into me.
The first thing I noticed, just before her gasp, was how poorly concealed her breasts were underneath her top. She is tall, just about my height at six feet, and since they're that much closer to eye level than most girls tits, so it's even harder to avoid staring at them every now and then even if she's wearing a sweater. I felt bad about that being my first thought, but I couldn't help it. She has amazing breasts, and I'd always admired them. Then came her gasp, and with it I caught the same soft jiggle of her breasts that had played itself out in my fantasies so many times... Then I realized the situation. There I stood, completely in the buff about five feet in front of one of Jen's best friends and she was letting her eyes roam, taking my dangling cock in for all it was worth while I went from flexing to standing stiff and awkward. I was glad I'd stayed in shape and only felt like a sloth. In those first few seconds, she just couldn't hide it, she just stared at my dangling member in all its glory before she ever tried to look up into my eyes in order to mutter an apology. When I think back on it, on that first stare, I almost shoot my load immediately. I love the look on a woman's face when she first sees a cock. When she did finally look me in the eyes though, it was evident that neither of us had prepared for this, at all. I stood facing her, iPod in one hand, my other hand held up in surprise, completely naked and shocked.
"I'm sorry, I thought you were out, I'm so sorry."
"Uh... it's okay," is all could stammer as she turned her back to me and bounced back out of the room as quickly as she'd arrived. Her ass looked so round and perfect as she went away.
"Let me pull on some shorts, shit, what did you need?" I called after her.
"Oh my god, I'm sooo sorry" she said again, "I just needed to grab a beach towel from the dick, I mean deck, I really had no idea you were in here. Jen said you'd be running. I called out. I didn't hear anything." I sprinted to my shorts and threw them on hoping the mesh could contain my cock enough to try and salvage the situation.
"It's okay; I've got shorts on now. I'll grab the towel, and we'll just laugh about it. Come on in, it's no big deal."
She came back in red in the face and giggling awkwardly. I stood before her in my running shorts, no boxers, and her in her bikini. She had her long black hair tied back in a pony tail.
"Gosh I'm so sorry"
"No big deal, we're adult. Let's get you a towel."
As I spoke I remained admiring her bikini clad body, she was an athlete in college and had remained a workout fiend ever since, leaving her with a well fit voluptuousness. But I particularly couldn't help myself from sneaking another glance at her breasts, and I felt myself growing hard in her presence. Her face had grown red and the deep maroon of her cheeks reminded me of what she'd just seen, and there was nothing I could do when the erection started up.
"She said there'd be some out on the deck"
"Sure" I said, turning away from her and opening the deck door, moving to the side to let her out. She passed by but the entrance wasn't that wide, and her hip bumped the semi-erection I'd desperately been trying to conceal.
"Ooops" she whispered nervously almost as if she had a hoarse throat, glancing quickly into my eyes as she passed, but keeping her focus on the towel hunt. I knew my growing fatness was visible from the way she tried to avoid looking at it as she went about getting the towel. When finally grabbed one from the rail and turned to face me, but I'd already retreated to the bedroom.
"Hey wait, come here so I can show you where we're seated."
I stood back at the door and she finally looked down directly and hard at the tent in my shorts. Something had come over her and she smiled.
"Thought so," she giggled, "I bet you need a cold shower now huh, haha."
