All week in Washington the meetings lasted til the wee hours of the morning. And they started up again at eight. Sheer torture. Finally, on the last day of this blasted convention, they let us go back to the hotel "early", 9 PM, so we can call the airlines and tell them we missed our 4 PM flight home, and to book us for another, about noon on Saturday. Rushing back to my room, I put my suit on and rushed up to the 38th floor pool, hoping to have a nice relaxing swim before hitting the sack. These twins on the elevator, however, had different ideas. As soon as the elevator doors closed, one of the twins took her robe off and asked if I thought she had a "cute" figure. Her braces and cute pixy haircut said she was about thirteen, but her body said more like sixteen or seventeen. The white halter top covered her budding breasts quite well, but the lights were so bright, that I saw the pinkness of her nipples, begging to be kissed. Her waist was ever so thin, flaring into the best looking pair of legs I could ever remember. Her bikini was one of those with sort of a belt of material around her hips, and was adjustable, sort of like curtains, so she could adjust how much of her bare little bottom was in view. Just as she turned her bottom towards me, her fingers reached behind her, I suppose, to cover up more of her behind. My cock almost tore a hole in my trunks as, instead, she revealed as much of her bare behind as the bikini would allow. Her legs had a deep tan, which stopped abruptly at the crack that separated her legs from her behind, which was pure virgin white. Then she backed into me, rubbing most of her bare bottom on my legs, and at the same time I could look down her top and see that her milky white breasts were just as smooth and cuddly as was her bare behind. Just then, the elevator began to slow down, and quick as a flash, she had her robe back on, and the three of us walked onto the deck of the pool. The lone teenage lifeguard looked at us, and assuming the girls were my daughters, said, "Officially the pool is closed, but if you promise to keep your eye on the girls, I'll lock the doors and you can swim as long as you like. Just turn off the lights when you leave." With a click of the lock he was gone. There I was alone with twin virgin princesses. Missy announced that since she was 20 minutes older, so it would be her "turn" first. Turn? Turn for what, I wondered. I didn't have to wonder long. The second twin quietly let her robe slip to the deck by the diving board, and revealed that her sun kissed figure was every bit as sexy as her twin's. She dove in the pool, and after what seemed like forever, came to the surface just a few feet from where I was standing. "I think we better call him, 'Daddy', in case the lifeguard comes back. Is that OK with you, Daddy?", asked one. "I suppose", I replied, "but what are your names?" "I'm Missy", responded the dry twin, "and my sister's name is Krissy. We're members of the Olympic Diving Team, and we are eighteen." I knew better, but if they were only sixteen, that was good enough, because we were in Maryland, and a sixteen year old is old enough to do whatever she wants to. Then Krissy called out, "Daddy! Will you help me? When I dove in, I lost the bottom of my suit!" Quickly I dove in and swam up to the nearly naked twin, I put my left hand next to hers on the lip of the pool, and my right hand around her bare waist and felt down to her soft round naked behind. "You certainly did lose your suit", I replied. Then Krissy wrapped both of her legs around me and begged, "Please don't spank me Daddy, I didn't mean to lose it." The look of despair and the tears in her eyes were genuine. Meanwhile my hand was doing a lot of cuddling and caressing, and had found its way between her cheeks to her almost hairless pussy. "Oh Daddy!", Krissy squealed in delight as I stroked her most secret parts. Figuring out the game they were playing, I decided to join in. Out of the water", I ordered in a gruff voice. Krissy swam over to the ladder and climbed out. My cock felt like it grew to about eight feet long as I watched her climb out. I remember getting turned on as a teenager, watching girls climb out of a pool, seeing a bare-bottomed thirteen year old was too much. She faced me and put her hands in front of her pussy, to conceal her shame as I got out of the pool. I noticed she was blushing all over, but her sheepish little grin told me she was in heaven! "That's not fair", interrupted Missy. "I said it was my turn first!" "If you interfere with your sister's spanking young lady, I'll paddle your bare bottom next", I scolded in a playful voice. Then I dove into the pool, retrieved Krissy's bikini bottom, and ordered both girls into the sauna. The sauna had been off for quite some time, but it was still warm. I took Krissy over my knee, and positioned her so that my cock was rubbing her bare, hairless pussy. Then I unhooked the top of her suit, and reaching around her, began to feverishly caress her bare breasts. Someone had left some baby oil in the sauna, and I squirted some on Krissy's round, squirming bare behind. With my right hand caressing her bare breasts, my left hand began slapping her naughty little bottom. I ran my middle finger up and down the crack of her bare butt, and everytime I touched her near her pussy she moaned with pleasure. Finally I began to try to insert my finger between her lips, into her love canal, which by now was dripping with lots of home made honey. Just as my middle finger inched its way in, Krissy exploded. I moved my right hand from her breasts to hold her little bare bottom, to try to keep her bottom from bouncing off the ceiling of the sauna. A minute later her climax became more controllable, and I inserted my well oiled thumb into her bare butt, and Krissy exploded in my arms for a second time. Meanwhile, Missy has been doing a little striptease for me trying in vain to get my attention. Now that Krissy is too exhausted to move, I picked her up and laid her down next to me, when she surprised me and said, "Please hurry and spank me, I can't stand the suspense!" Then she crawled over my lap, and I put my finger back in her hairless pussy, my thumb back in the hole of her bare round bottom, and began to spank and alternately caress her cute little butt, with my other hand. Seconds later Krissy begins squirming again, and in no time is she is having her third violent orgasm. Finally finished with Krissy, I notice that Missy is now lying on her tummy, fingering her pussy, working herself up into quite a little frenzy. So I quietly sneak up on her, and began to fondle that cute little bare bottom that I first became aquainted with earlier. Kneeling down, I insert my tongue into her virgin asshole, knibbling my way to her pink slit. Missy is begging me to slam it in, "Fuck Me, Fuck Me, Fuck Me!!!", so I sat on her milky cheeks and inserted my dick in her little baby pussy. I could feel the head of my dick at her tonsils! Slapping her pussy with my balls, I exploded inside Missy, then I collapsed on top of her. After a while, we got up and dressed. Heading for that very same elevator, both Missy and Crissy put their hands inside my shorts, and when we got inside the elevator, well, you know the rest.
