A younger family moved into a house in my street. They were a husband and wife, who would have been in their late 30's, with a young son and they led a fairly quiet life.
We would occasionally chat in the street and a couple of times I returned their dog after it got out of their yard. Just general good neighbourly stuff.
It was a warm day, so I decided to head to the beach, which I would do several times a week. This day I decided to go to the 'clothing optional' beach, which I would occasionally do. The beach was long and isolated, so I would usually walk past where the majority of the people were, so that I could enjoy the nature and solitude and the invigorating feeling of being naked out in the open.
The beach was also used by dog-owners, who would enjoy the freedom of allowing their dogs to roam free, along with other 'clothed' beach walkers. Usually I would walk along the beach, occasionally stopping for a swim along the way. Passers by (clothed and unclothed) were usually quite friendly and would smile and say hello and sometimes have a bit of a casual chat, especially if there was a dog in a playful mood, though I usually only chatted with women, generally not making eye contact with the men.
Occasionally when my hormones were on fire, I would enjoy the thrill of masturbating out in the open once there was no-one around. This day, I hadn't been to that beach for a few weeks, so I was feeling a little extra invigorated getting naked and walking along -- feeling aroused and not far from an erection. In the distance there was a woman, fully clothed, with a dog walking towards me and I was thinking that once I had passed them, I would look to relieve the tension that my hormones had been building in my balls. My mind was wandering as I approached the woman, until she came out with "Hello neighbour!"
I snapped out of my daydream to look under the hat and behind the sun-glasses, to realise that it was my neighbour Jane and her dog!
"Ohhh... ummm.... Hi Jane" I stammered. "I.... Umm... probably shouldn't be meeting you here like this!" I tried to explain.
"Isn't it a beautiful day to be out here" she smiled.
"Ummm... yeah it is.... but you probably shouldn't be seeing me here like this" I continued to stammer, my mind racing.
"Hahaha... that's cool" she said. "Nothing I haven't seen before" she laughed, looking down at my exposed cock. "I've always wanted to come here and swim naked, but my husband won't come and I have never been game to strip off just by myself -- a woman on her own..." she smiled.
"Ummm... yes... it is nice" I smiled, slowly regaining my composure. "You should try it, there is no-one around at this part of the beach, and you can see people coming long before they get to you" I added.
"Would you mind if I joined you for a swim?" she asked. "I would feel safer with you around" she added.
"Sure -- if you are comfortable with that, why not? The water is beautiful today" I smiled to her, feeling a stirring in my cock at the thought of her getting naked.
We walked up the beach to put our things on the sand and Jane quickly stripped off her t-shirt and skirt, revealing her bikini, as I patted her dog, trying not to watch her getting undressed.
"Oh well... here goes... " Jane giggled nervously, and I looked up to see her undoing her bikini top and exposing her small breasts, our eyes meeting. I couldn't help noticing that her nipples looked a little aroused and I could feel my cock stirring.
"How does that feel?" I smiled to her.
"So far, so good" she giggled, tossing her bikini top onto the sand.
She then slid down her bikini pants, revealing a thick patch of hair between her legs, and I felt my cock growing hard at the sight of her stripped naked. As she tossed her bikini pants next to her top, her eyes took in my growing erection.
"Ooopsy!" I giggled. "I'm not used to having an attractive woman undress in front of me" I grinned nervously, not sure what her reaction would be.
"It's nice to know my 'mum-body' can have that effect" she giggled, sub-consciously brushing her fingers over her firming nipples.
"Shall we swim?" I asked her, heading towards the water and wanting to get in the water to conceal my erection, before I scared her off.
It was incredibly invigorating walking down the beach with an erection, next to my naked neighbour, and I quickly dived into the waves, with Jane not far behind.
"How is that?" I asked her, as she appeared from the water next to me.
"Wow!" she grinned. "Very exciting!" she giggled.
We chatted and laughed as we stood around in the waves, with her regularly diving under the water and my eyes watching her ass.
"The water is quite refreshing" I smiled to her, my eyes drifting down to her very firm nipples, our eyes meeting. "Which is lucky for me!" I laughed, implying that my erection had subsided due to the cold water.
"I was quite enjoying the view" she grinned at me cheekily.
We left the water and I closely followed her up the beach watching her shapely plump butt and felt my cock stirring, but not to the same level as before our swim.
"Do you mind if I walk back to the car park with you?, I asked her.
"Only if we can do it naked" she giggled mischievously.
"Sounds like a deal" I laughed, noticing that her eyes were drawn to my slightly aroused cock.
We walked back towards the car park, chatting and laughing, and stopped for a last swim before we got too close to the 'crowd'. I discreetly fondled myself as we were in the water, wanting Jane to see me in an aroused state before we got dressed to leave. We faced each other, watching each other getting dressed, her eyes fixed on my partially aroused cock.
"It looks like you might need to take care of that when you get home" she giggled.
"Maybe.... " I chuckled back to her with a mischievous grin.
We said our goodbyes and headed off to our cars. I needed to do some shopping on my way home and replayed the time at the beach with Jane -- my thoughts fluctuating between how amazingly erotic it was, to guilt and "what the fuck have I done" As I arrived home, I saw that Jane's car was in their driveway and thought that I needed to go and speak to her to make sure that we were ok.
I knocked on her door and after a bit of a wait Jane appeared at the door with a nervous smile, her face looking flushed and wearing the same t-shirt and skirt from the beach, though her nipples were firm and clearly visible through her shirt.
"I... umm just wanted to make sure that we were ok" I said nervously. "It wasn't right for you to see me at the beach like that and I hope it wasn't too inappropriate for you" I continued.
"Hahaha" she giggled. "Yeah... we are fine" she smiled. "I loved it" she added, ".. and yeah, we should probably keep it to ourselves" she giggled.
"Hahaha... deal" I smiled, relieved at her response. I couldn't help lowering my eyes down to her firm nipples protruding through her shirt and as we chatted, I noticed inside behind her that her bikini was on the floor beside the sofa.
She nervously noticed my glancing at her nipples, and looked behind herself to see that I had seen her bikini laying on the floor. "You weren't the only one that was excited at the beach" she giggled nervously.
"Oh... I hope I didn't interrupt anything" I smiled.
"You did... but that's ok" Jane giggled. "I was just thinking about how exciting it was watching you getting aroused as I got undressed at the beach" she smiled cheekily.
"You were surprised?" I smiled flirtingly.
"I was... I didn't expect it... and it was a bit flattering seeing that reaction" she smiled.
"It was no surprise to me" I grinned, feeling myself growing in my pants. "An attractive young woman getting naked in front of me... what isn't there to like about that?" I laughed, looking again at her firm nipples.
"A woman with a 'mum body" she laughed.
"Well... you saw what I thought of your 'mum body'" I smiled.
"Yes, I did" Jane grinned. "And I liked it.... and I'd like to see it again" she grinned, looking down at my pants. "Or have you already taken care of it?" she joked.
"Haha... no I haven't, but now I know that we are ok, I have a clear mind and maybe I will" I grinned. "And I can let you get back to what you were doing" I smiled, my eyes glancing towards her bikini on the floor.
"Maybe you could show me just one more time, to help refresh my memory" she giggled nervously.
"What would you like me to show you" I teased her, feeling my cock growing firmer in my pants.
"Ummm... if you still have the same reaction to my mum body" she giggled.
