20m, last year my Father had to visit Spain where another company wanted to merge with his. Having been on the rocks with my Mother at the time he thought it would be best to bring her and myself with him. Thinking this would bring the spark back into their lives he booked a five-star hotel for the month. My Mother and I were more than excited having never been there or Europe in general. We did not know what to expect at all. The moment I found out about this I began looking up things to do while there. Making a list at the very top was to hit some beaches since it was the middle of summer there. My Mother had the same idea packing a carry on bag of just bikinis and towels. When we got there it was everything you seen in movies plus so much more. The first two weeks my Father would be meeting his potential partners during the days working with their company to see how they function and stuff. So it was just my Mother and I, which was much better than their bickering all the time when he was around. Our first day we decided to find a beach so she had me look up the closest one. Telling me she can’t wait any longer to get in the water she didn’t care how nice the beach was only that it was the closest. I found a highly rated one on google and we called a taxi and went straight there. It was mid day on a Monday so there won’t be a lot of people there the driver told us. She was even more excited about this since crowded beaches aren’t relaxing. When the driver dropped us off my Mom had me pay him as she ran off to the beach. When I caught up to her standing at the edge I soon realized what she had moments before. Unlike the U.S. this was Spain and it was very very normal that this was a Nudist beach. My Mom’s face was red and not from the sun and I too started to blush as mature men and women walked around with their privates freely flopping in the wind. She smiled awkwardly at me and I shrugged telling her I had no idea this was even a real thing. She said we should just go out there in our bathing suits and act as if its a normal beach ignoring the other people since there really wasn’t anyone there. I accepted and we found a nice spot pretty much secluded to ourselves. My Mom didn’t waist any time running to the water and diving in as I laid out looking at all of the old women in the distance. I had never seen mature women completely nude in person so seeing their unfit bodies was new to me and surprisingly a turn on. I think that was because it was so new and raw that my body couldn’t say no. Once my Mom got back from the water she laid down beside me to get some sun telling me how nice the water is. I could care less about the water at this point trying to make my half hard dick unnoticeable to her. A few minutes passed and I saw two older men walking our direction. The one was fat with his stomach completely overshadowing his dick and the other very average. They came straight over to us and began talking to us. Unable to understand Spanish my Mom told them and they repeated themselves in English for us. The average guy said, “this is a nudist beach and you must know it is very disrespectful to the rest of us that you wear your bathing suits.” Standing there with very aggressive looks they made it a point that we must either strip or leave. My Mom looked at me with a disappointed look as she tried to reason with me on why we could stay. Telling me she didn’t mind if I didn’t I then agreed. She said to the men that was fine we will strip so they can go back to enjoying themselves. They then shot me some mean looks before going away. Mom then smiled at me and said, “I guess it is no big deal seeing your mother naked”, as she untied her top straps. Watching her ample tits bounce out of the top was more than amazing having always wondered what they looked like. Stunned I never imagined they would be so amazing though. She has a thin waist from working out a lot and around 5'7" with 32DD. She then continued to take off her bottom and looked to see if I was doing them same. I froze since my dick was now hard as fuck and I feared what she would say. She seemed to notice my embarrassment and told me she will go to the water now so I could undress in private at least. Watching her walk away as her ass switched from side to side did nothing to help my problem. So I just pulled them off so those two guys wouldn’t come back. I tried to find a comfortable way to hide my dick, but nothing worked as it struck a flag pole pose. I bet if my Mom looked at it from the water she could have (not saying I am huge) it was just that obvious. A palm in the desert. Soon after she started to come back and I decided to roll over on my stomach. I could feel her walking up from behind me and her voice call to me, “cute bald ass hun”. I couldn’t help but laugh since she was probably used to the site of my father’s hairy body. We hung out for a while like this and no matter how much time passed my dick wouldn’t go down. Buried in the sand beneath me I could feel it twitch at the sight of every naked woman passing. My mom must have figured something was up as she watched my back change from pale to crab red. Telling me she was going to take a nap she also turned over onto her stomach looking the other direction. I took advantage of this moment and rolled over feeling the sand stuck to my chest and stomach. I decided to head to the water thinking it might be best to cool down my manhood. As I walked up to the water it was super cold on my feet so I took my time getting in. This was long enough for a couple of mature women to approach me asking if I was alone. Watching as their eyes flashed from my dick to my face I knew they were after a young eager guy like me. Feeling flattered they were so flirtatious I played along to see what would happen. They were both easily in their 50’s with bodies to match. Tear drop breasts and average aged bodies I never thought I would find them attractive until now. Must be a mixture of curiosity and hormones. This did nothing to help with my manhood problem as they continued to flirt and one even gestured her hands while talking, which slightly grazed the tip. They continued to do this while asking me all about men in the States. The one even went as far as grabbing the shaft one good time giving it a slow stroke while asking if we like experienced women. I allowed this since it needed some attention anyways. We talked for a couple more minutes as they now tried to get me to come lay with them. Very tempted we were interrupted by another as my Mom come walking right up next to me. Surprise by her presence I nearly forgot I was with her. She shot dirty looks to the women who were much older than her as she took me by the hand asking me what they were talking about. I just told her they were wondering where I was from as she looked back at me knowing full well I was full of shit. She then asked if I would come back and put lotion on her back as the older women got the hint walking back to their spot. I followed my Mom to our spot where she handed me the bottle of cream. She smiled and said, “wow I never imagined my own Son would be a target for such mature women.” I told her it was nothing to worry about as I caught her eyes locked on my hard dick. Looking up she blushed and told me she could see why they were so interested. This was like gas to the fire as my dick twitched having never heard something so provocative. Hearing my own Mother say that drove me so wild I felt my dick swelling more as she glanced at it several more times. I almost busted at the thought of this all. She then laughed and said, “maybe you don’t need the cream, seems like you have enough of your own.” I then glanced down at what she was looking at to see a stream of precum pouring from my dick. Looking up at her my eyes drifted up her thick legs to her stubbly pussy then around her round tits and juicy lips. By the time I got to her eyes I could feel my dick throbbing again and more precum was surely leaking out. She saw my lust growing and then asked, “can we act as if we are not Mother and Son for just today?” I nodded my head slowly unable to speak as she crawled closer reaching out for my dick while keeping eye contact. Feeling her hand grab it drove me insane as she bent down putting it straight into her mouth. I collapsed as she took my length. Swallowing my dick like I have never had it sucked before she was so passionate. I couldn’t believe what was happening as she cupped my balls with her hand and swirled her tongue around my tip. She told me that it has been nearly a year since she has done this with my father and much longer since she had sex. The sound of that word was like lightning through my body. She crawled on top of me and lined my dick up with her pussy. I could feel it dripping wet as she slipped my tip past her lips. My heart slammed as I zoned out on her. She slowly slid it in sitting down on it as I could feel inside of her. It was amazing how tight she was and no surprise since she works out so much and hasn’t been taken by a man in such a long time. I am not going to lie all of the energy passing through me was so overwhelming that I couldn’t last more than a minute before I had to come. She pulled me out and stroked me as I came all over my stomach and her hand. I never came so much and she never seen so much come as she told me this laughing with excitement. Squeezing the last few drops out she complimented me on how hard it still was. I then asked her is she still wanted to continue and oh did she! Climbing on top of me without another word she started riding me again this time much harder. The cum was now spilling off of my sides as she bounced around. She even laid down on top of me rubbing her huge tits all over my chest covering herself in my cum. When she rose back up I could see strings of my sticky cum band from our bodies as she rubbed it into her tits. She was wild and going crazy as she then slid her fingers into her mouth tasting me. I could feel her pussy tighten when she did this as she began to come on my dick. Grinding harder now she moaned with her finders in her mouth while her other hand slid across my stomach only to scoop up more cum to taste. Feeling her pussy surging she came and I couldn’t help but cum with her. Trying to warn her it was far too late I unloaded inside of her. I am not sure if she knew so I kept my mouth shut scared she might flip. When she finished she looked down at me with a bright eyed smile and said, “come let go get clean in the water”. I followed her down to the water where she and I washed the cum from out bodies. I was so happy to see how cool she was about what just happened. We left the beach soon after and spent the rest of the night with my Father. Every day after while my Father was working we went back to the beach and continued our fun as a couple. In the end my Mom convinced my Dad this trip saved their marriage so he made the deal and we now spend half the year in Spain.
