Embarrassing Erection at Nude Beach

I've always been easily aroused, even from the sight of my own hard-on: it points straight up, it throbs, and when I was younger I imagined that girls would be embarrassed for me if I got a boner, and they'd find it sexy/funny.   It wasn't until later that I realized it made them wet between the legs!

With my fear of getting an "inappropriate" erection (and the high likelihood that I would), in the early 1990's when I was still in my 20's I used to love going to our local nude beach, a cliff-protected cove south of San Francisco called Grey Whale Cove.    If I could find a few hours to spare, I'd go there to be nude in the sunlight, and to see if I could be seen without getting an erection (in that context, getting hard *would* be embarrassing). The beach wasn't usually crowded but there were usually five or ten women, sometimes there alone, along with the usual smattering of gay guys and saggy old men.

I'd lay my towel down at one end (the beach was about half a mile long), ideally within sight of a woman but not so close to be intrusive.   Once I'd gotten "accustomed" to being nude--a process I had to go through on every visit--I'd "dare" myself by walking nude along the surf, without my towel.   If I ever stopped to chat with a woman for more than a few seconds, I would surely pop a boner.   But (whew!) it was always just short greetings.
But one day, when I had walked nearly the whole length of the beach, there was a really beautiful girl, about my age, walking in the surf nearby--maybe 50 feet from me.   She had firm, tan breasts with the kind of nipples and areolas that I just love--like pink pencil erasers surrounded by half-dollar-sized pink aureolas.   Just RAVISHING. And she was wearing a really sexy, gold lame' bikini bottom, with no top  . The fact that she wasn't completely naked is what got to me, since I was completely nude.

To my genuine embarrassment, I got an immediate and impossible-to-hide erection.   I was imagining (I couldn't help it!!) the contrast between her pussy hidden by her bikini, and my naked and very stiff penis.  And I was imagining her coming up to me, breasts dripping wet, nipples erect, and her seeing my cock so hard that even she could have given me her bikini bottoms so I could hide my "shame," my cock would poke straight up and her bikini panties would only half hide it.   I was that hard!!!
I was so embarrassed I immediately sat down in the sand right where I was.   Well, she didn't notice me, but two women nearby did!   One of them gestured to the other and they both looked at me sitting pathetically on the sand, my knees up in a vain attempt to hide my stiff penis.   Oh god!   I hoped that my cock would relax as I sat there, but it never did.   I sat there just throbbing.   And my towel was all the way at the other end of the beach!!
I sat for five or ten minutes and my boner never went away.          

                                                                     I realized I would have to take a completely mortifying "walk of shame," the most embarrassed I've ever taken in my life, with my stiff cock bobbing for all to see.   But I was also very excited, to the point where my stomach was trembling with butterflies.   Halfway up the beach, as I walked back to my towel, this very sweet-looking girl, younger than me, got a shocked look and put a hand to her mouth.  I was too embarrassed, honestly, to look her in the eye.

When I got back to my towel my dick was just glistening with pre-cum.  My "neighbor" was a 40-something woman on her towel about 20 yards away.   She was reading and didn't notice me when I came back.  By that time I was so out of my mind with excitement that I lay half on my side with my erection in clear view so she could see it if she looked toward me.   And before long, she spotted me.   To my excitement she locked eyes on my cock and grinned slyly.

I was so wildly turned on I started gently running my fingers up and down my cock, teasing myself.   Before long I could control myself no longer, and did something I had never, ever done--I decided to masturbate in public.   I rolled onto my back and just very very slowly started stroking my rock-hard cock.   I couldn't see her (she was behind my right shoulder as I lay now) but I knew she was directly watching me.   I gently gripped my cock and started fucking myself slowly with my hand.   Almost instantly I had to arch my back and started to thrust into my hand.   I let out a groan and just shot out spurt after spurt of cum.   The first blast hit me square on the mouth, the second spurt hit my chin, and the rest of my cum formed a big warm puddle on my chest and stomach.   Oh god!!   It felt soooooo good!!!!!!   I was absolutely spent but so, so thrilled that she had willingly watched me masturbate.
I waited a minute or two then got up to wash off in the surf.   When I came back she smiled warmly and came up to say she thought it was wonderful.   It really made my day.   It made my year!!!   And it still makes me SO hard thinking about it!
