Tent Camping at the lake

I set up my small cabin tent, just big enough to stand up in, and the view out the front door was towards the road between the boat ramp and the other sites and showers. The holiday weekend brought out families with teen daughters. I soon realized they all walked to the boat ramp and to the showers frequently. I was sitting on a camp stool in my tent nude and wiping off with moist towelettes and I saw two teen girls in bikinis walking right by my tent. They had short cut through my camp. After they passed I heard them giggling out my side window and saying how huge my junk was. I looked out the side window and followed thier sexy bikini butts until they reached the boat dock. My cock was swelling as I put on my speedo bikini swim suit and I went outside to work on my camp some more and check the girls whereabouts at the dock. After a while sat down at the picnic table in front of my tent to enjoy the shade of the shelter. When I saw the girls returning my cock got hard. I was sitting on the picnic table bench leaning back with my elbows on the table and my legs open wide. The girls saw me there and slowed down to wisper to each other. But they continued walking straight towards me and my cock was stretching my speedo and I didn't even try to hide it. One of the girls looked just like Miley Cyrus with long lean legs and a high and tight butt and tiny tits. They were looking down at my bulge as they got within a few yards of me then they veered around behind me as they passed. The other girl looked like Selena Gomez, black hair, pretty face, round butt,and with huge full tits that sloshed in her bikini top as she walked. SHe was short though, barely five feet tall. Her butt cheeks snapped with each step. They were talking in hushed tones but I could here their voices shaking as they said I was older than their dads and they described my massive boner in my speedo. The Selena Gomez girl spun on her heels as she took another long look and her fat tits were jiggling and swinging in her bikini top. I watched their sexy teen butts walk away and I got an over the shoulder look from the Miley one too. I watched them go into the shower house to wash the lake water off their precious bikinis and out of their hair. I thought about being in the mens shower next door and hearing them over the wall talking about my big cock. It would be so hot if I was in there jacking off real hard and loud and my wet balls were slapping my ass and fist and hearing them saying,"OH... MY... GAWD..., sounds like someone is jacking off in there". I was ready to go in my tent and jack off but saw the girls returning. Now I studied their tits and hard flat bellies as they approached. They were doing their best runway model walks and were right in front of my picnic table when I told them they could sit here in the shade any time they wanted. They stopped and I rubbed my hardon under the table as I leered at their sexy hard nipples through my dark sunglasses. Selena girls eyes were darting downward and she knew what I was doing under the table so I told them I would stand up so they could look at my bulge up close. They looked at each other so I stood up and it was throbbing. My hand was rubbing the head through the thin fabric as Miley girl asked how big it was. I told them I was over eight and a half inches fully hard. I said I was going in my tent but they could wait there in the shade as long as they wanted. I turned and ducked into my tent leaving the flap wide open and watched the girls sit down at the table. I peeked around left and right out my door opening for other campers then looked at them and slid my swim suit down so I was standing there nude and rock hard. The girls were watching and moaning, "Oh... fuck yeah. Thats a huge dick. Look how thick it is". I jacked it up and down for a couple minutes then sat on my camp stool where they had first seen me and I held it upright for them. Then the Miley Cyrus look alike said quietly, "Fuckin beat it Mister, you dirty fucker". I jacked it hard my big full balls were swinging and bouncing on the stool seat with loud thuds. Selena girl said, "Damn Man, what a nasty old fucking pervert. Jacking off in front of girls." I told them they loved watching and I loved them watching me. I stroked for them with my legs spread wide and soon I was feeling my balls aching to cum, but then the girls got up and said their dad was waving them to the boat at the dock. I stood up wagging my hard cock and asked them to please come back later after dark for another show.
I sat in my tent after dark waiting and looking around for the girls. I stayed semi hard thinking about them and I took off my speedo again and stroked it to a full erection. My cock was pouring precum out and sliming down my shaft so i had to stop and I went outside and sat at the table in the dark wearing only a large t-shirt that fell well below my hips. I finally saw in the darkness a flashlight coming my way. The girls walked into my camp and sat at my table across from me . They were both wearing large t-shirts also as coverups. I told them to turn off their light and I got up and went to their side of the table and lifted my t-shirt a little until my dick was exposed. I let them watch it grow fully hard. I said I was going to cum for them and they could watch with their flashlight. My throbbing hard cock was between the two girls shoulders and I stroked it. They both turned and looked at it. I jacked it hard to bang my balls around and said to them, " I know both of you want to touch my big cock. Don't you." Then the girls got up and went to my tent door. I followed, went inside and stood in front of them and I asked if they would spit on my cock so i could use it to lubricate it. The Selena girl leaned forward and spit several times. I slicked it up and down my cock for a couple minutes and my cock head flared out. My cock was swollen so thick and long and felt fantastic. I took off my t-shirt and was nude. I told her I needed more spit so both of them spit and I drooled it down my cock. I said I was so turned on fantasizing about their hot nude bodies and I was going to cum a lot. Miley said, 'I've never seen an older man jack off before. It's hot." Then Selena told me they were nude under their t-shirts and asked me if I wanted to see them nude. My cock stiffened even more watching them take off their shirts and stand before me nude. I asked for more spit. Both girls bent over and spit several times on it until it was slimy and dripping and I stroked it fast until the cum arced out to the cooing and encouragement of the them telling me, "Shoot that load... cum hard, Mister. We want to see lots of cum." It splattered on the tent floor with loud thuds one spurt after another. As the girls shined their flashlight on my cock and cum puddle I told them I wanted to jack off again, to their nude bodies and to meet me in the shower house in about 30 minutes. I said I wanted them totally nude and maybe cum on their tits. They asked me if they could feel my cock and I let them grab it and pump it. Cum and spit flipped off it and on Selenas thighs.
