Email to "Cavegirl" cavegirl@brtdata.net We used to go to the beach when the girls were littler, but hadn't in almost two years, because it was such a long drive. But we decided one day to pack up and head for the ocean for a few days, and little did we know we would end up staying for over a week. We packed our suits, blankets, a tent, sleeping bags, and lots of sun-block. After a long 12 hour drive, we arrived and rented a small cottage right on the edge of the sand dunes, and about 100 yards from the ocean itself! There were three other cottages in a row, but judging from the lack of footprints in the sand around them, they were for at least today uninhabited. But of course it was Wednesday, so I was sure they'd fill up before the weekend. Until then we seemed to have a whole beach to ourselves. The girls were so excited that they left me to unpack into a very small but cozy cottage, while they sprinted for the ocean to feel the warm salty water on their feet. The weather was beautiful, and the promise for a good vacation was looming. I unpacked all of our clothing and locked up the cottage, then wandered down to the beach. It was starting to get dark, so we just walked down the beach one direction looking for shells and splashing each other. We got carried away and soon all three of us were soaked. It was only natural after that to start pushing and pulling each other into the shallow waves lapping at our knees. Jari, now 9, is short for her age, maybe 4' tall at the max, and I just picked her up and threw her into the deeper water. She just stood up and ran for the dry sand with Kari on her heels. Both girls stood there and looked at me guiltily, whispering to each other, then started stripping their clothes off. Before I could even offer my opinion on being out here on this public beach naked, they were both running back into the surf without a stitch on. I looked around both ways and there wasn't another human in sight, so thought nothing of it. That is, until the girls swarmed me and pulled my trunks down to my ankles, and Kari engulfed my cold-water-shrunk cock into her mouth. Jari joined in and was massing my ball sack, and soon I was sporting a rock hard cock pointing at the sky. I continued to nervously glance up and down the beach while the girls continued to service my swollen member, and if I wasn't nervous enough, Jari said "Fuck me right here on the beach, pleeeeeez?" The words were hardly out of her mouth and she lay down on the beach, stuck her skinny legs high into the air, and pulled the puffy labia of her vagina wide open to show me her very moist pussy. Dammit, she knew that never failed to get a reaction from me. It was getting pretty dark, so I decided to just fuck her, and I was just about to just about to kneel between her legs and I remembered that the girls are always a little competitive in these circumstances, so I glanced at Kari who still had my cock in her hand, and she just nonchalantly followed me down to a kneeling position between Jari's out stretched legs, and guided my cock into her sister's inviting pussy. Then she looked into my eyes before letting go of my cock and said "Go ahead daddy, but I want fucked on the beach tomorrow!". So I lowered down between Jari's legs and slipped the head inside of her. Unlike grown women who when fully aroused you can just drive into them in one stroke, I'd never been able to with Jari or Kari, they were just too tight. But within a minute I had stroked my way fully into her, and her hips were thrusting against me as usual, and within a couple more minutes our hips were slapping together and my cock engorged a huge quantity of cum deep inside of her cunt. I lay there gently on top of the spent little girl, wishing that I had enough to give to my other sweetheart, who knelt beside us watching every inch of the action. But she seemed satisfied that I had promised I'd fuck her on the beach tomorrow. It just occurred to me that I was so enthused with boning my 9 year old that I had stopped watching the beach for other people. Looks up and down the beach found them empty, much to my relief, but when I looked up towards the cottages a football field length away, I saw a woman standing beside one of the empty cottages. When she saw me she turned and disappeared into the brush behind the cottages. I was grateful that it was getting pretty dark, and perhaps she hadn't seen anything very clearly. All of our clothes were soaked and sandy and impossible to put back on now, so I raced the naked little girls up to the cottage where we showered and dressed. I was now worried about that woman. That night I made sure the girls were both well serviced with my tongue and fingers, and tucked them into their own sleeping bags. The long drive and a beach screw were all we needed to put us to a long deep sleep. The next day I woke up late to find the girls already down at the beach. As per my stern instructions, they were not to go into the water unless I was present. As I peered through the cottage window, I could also see several other people combing the beach for shells, including a boy and a girl, apparently with their mother. The boy looked to be about 10 and the girl, about Jari's age. The woman was a slightly heavy blond, maybe 35 years old and about 5'9". The clothes didn't match the woman I saw the night before, but I wondered if it could have been the same woman. Thankfully the girls had bothered with clothes, so I put on some shorts and my sandals and wandered out towards the girls. As soon as the spotted me, instead of running to give me a good morning hug as was traditional, they immediately headed for the water and by the time I reached the waters edge they were swimming. The woman and her family had set down a large blanket about 100 yards from us and close to the water, so I splashed my way along the shoreline in her direction. I hadn't gone 10 yards when the girls sneaked up behind me and tackled me from behind, where I landed in the shallows on my back and both girls pummeling me with their soft bodies. Thinking this was just an innocent little wrestling match, I playfully fought them off, when I suddenly felt a hand go inside my shorts between the girls and I, and Kari whispered in my ear "Remember, I get fucked on the beach today - you promised!" As she was saying that the hand stroked my cock to full hardness, as they always did. I looked around to make sure no one could see the girls hand in my crotch, and just when I was comfortable with the notion of no one seeing her molest me, another hand joined in and I soon had two little soft hands stroking me. I rolled a little towards the ocean and let them play. They truly enjoyed making me hard, and just as suddenly as they had tackled me earlier, they pulled their fingers from around my hard cock and jumped up and back into the water to swim. So now I lay there awkwardly alone and with a huge hardon. I laid there as long as I could, hoping it would go down, but the watching them frolic in the surf, their tight little bodies running to and fro, and the thought of fucking Kari on the beach tonight kept creeping back into my head and it just wouldn't go away. I was laying there still for almost 5 minutes when I noticed a shadow approaching below my feet. I rolled over and looked that direction and saw the woman walking towards me alone. She smiled as she approached, and I smiled back. I didn't want to look too silly laying there in a fetal position on the beach, so I lay back as if to catch some rays. That was a huge mistake, for my hardon, much to my disappointment, was still at full mast. As soon as I could feel the fabric of my shorts pressing hard against my cock, I turned quickly on my side to try to conceal my horniness. Trying to hide my embarrassment, I introduced myself and we started talking, and after a few minutes she sat on the sand beside me. Her name was Cindy, and she was here on a weeks vacation. Her husband had custody of the children usually, but the divorce gave her the kids for the summer, and she decided to spend a week here for some sun and fun. At lease my hardon had gone down. But not completely. She was rather pretty, and maybe 10 pounds overweight. But she looked happy and healthy, and best of all, very friendly. We talked on and off for a couple of hours, with brief interruptions from my girls and her kids, and we decided that we should all have dinner together at a local pizza parlor tonight. "Are you going to fuck her daddy?" was the first thing out of Kari's mouth when I told them we'd become friends and would be having pizza together. "Kari, I barely know her! And you don't want to let on that you girls and I are lovers; she probably wouldn't understand, and report us to the police." I had lectured them both several times about revealing our sexual antics beyond us three, and they both had kept their promises to be discrete. I told the girls that it might be a lot of fun to have them to play on the beach with. After Jari made a remark about the boy being cute, I also told them that the boy was of an age that he might be attracted to them, and that since the boys were old enough to produce sperm, any sex with them now was out of the question because it could get them pregnant. That seemed to put a slight damper on Jari, but she got over it quickly and we got cleaned up and drove to the pizza parlor. While gulping down pop and pizza and playing video games, the 4 kids slowly warmed up to each other and were already teaming up for beach games the next day. I welcomed the idea, since I could finally get some peace and quiet on the beach for a few well deserved naps. Cindy and I talked for a long time about our past lives, and I could see we would get along just fine. On the way home I reminded Kari that tonight was the night we would fuck on the beach, and once we arrived at our cottage, right next to Cindy's, we sneaked out into the darkness and down to the beach, with Jari wanting to stay inside and read. Kari and I walked hand in hand to the surf, where I knelt before her and removed her clothes, then carefully laid her down on the warm damp sand and let my tongue explore her moist opening. Two minutes hadn't passed when she was pulling on my ears and begging me to slide another appendage inside of her. Not one to disappoint a nympho with a tight pussy, I knelt between her legs and slowly worked my cock into her bald vice-like pussy and stroked her slow, then fast as she started to come, and I dumped a hole day's worth of horniness into her receptive cunt. She had come hard, and was laying there limp as I my cock made a plop sound as I pulled it from her pussy. I then lifted her into my arms and carried her up to the cottage to clean her up and put her to bed.
