This is a fictional account with everyone over eighteen. Sorry for the long rest. Just very busy and needing a break. Next chapter coming quick.

Friday was a disappointment. I wanted incredibly to get together with Anna again, but Penny dragged her off to the mall because she needed some things. Anna promised we'd get together later, which apparently wouldn't happen either, as she texted me her parents announced they were taking the whole family out to dinner. I was feeling sexually frustrated despite the hot sex Anna and I had the day before. I tried to be constructive, going to the store myself for college supplies.
When I got home, I could hear fairly loud music coming from the basement. I figured Darci was home. I dropped my purchases of notebooks, pens, and other school supplies on the stairs leading to the second floor. I'd wanted to play some Wii anyway, so I bound down the stairs fully expecting to find Darci alone. To my surprise, Katie was with her and they were playing with my Wii.
Darci spotted me coming down the stairs and yelled, "Hey, brother."
"Hi."
"Oh hi, Davey," Katie said looking my way with a smile as she took her turn at golf.
"Hey, Katie," I replied, glad to see her again.
I flopped down in a chair and watched Katie work the controller. She had a quiet grace the way her body moved. I checked her out, admiring every curve in her cute body. She was a good four or five inches shorter than Darci's nearly six feet. She was not as thin as Darci, but her figure was well defined in all the right areas, with breasts close to Anna's in size, an ass to die for, and nice long blonde hair approaching the middle of her back. Cute and sexy were definitely good adjectives to describe Katie.
"Want to play with us when we finish this game?" Darci asked.
"Yeah," Katie said, as she ended her turn with a bogey on the hole.
"Sure," I replied.
Darci and Katie each took one more turn then decided to quit their game so we could all play. We switched games to Mario and each took a controller.
We played Mario Kart, racing for a while all together, and then switched to tennis. Katie had trouble with the swing for tennis so I demonstrated how to do it. She still had trouble so I showed her my standing behind her as I guided her hand. As close as we were, I could breathe in her perfume and the scent of her shampoo. Her amazing ass moved below my crotch but that didn't stop her from wiggling against me with her back too as she tried to perfect the swing. She wanted me to keep showing her with my hand on hers. As I did, the motion of her body rubbing against me had my cock reacting. She eventually got it and I was able to step away.
I tried to discreetly look down and see how bad my reaction showed. I thought I might be safe but when I looked up, Darci was looking right at me with a big smile. I began to think they'd played this game with me on purpose when Darci announced she wanted me to show her the swing too. I was forced into repeating the same procedure with my sister, but this time her height had her ass directly rubbing on my shorts.
I'd decided earlier in the day to wear basketball style gym shorts to the store with just a t-shirt on top. That decision was proving difficult now as the stimulation from the girls wiggling bodies was more effective against me in these thin shorts. I had the sense that they knew it too and were teasing me on purpose. Unfortunately, knowing that they intended to arouse me was little help from preventing it from happen. It might have even added a measure of eroticism to think they were trying to get me hard.
Pretty soon Darci got the hang of the swing and I was able to back away. This time I didn't need to look down to know I had a problem. I looked over at Katie sitting on the couch and the smile on her face left little doubt about her recognition of my dilemma. I excused myself to the bathroom.
In the bathroom, I dropped my gym shorts and boxers down to free my raging hard-on. I wasn't completely hard, but hard enough that taking a leak took a good while just standing over the bowl before my dick began to subside enough for me to go. I had just finished when Katie knocked on the door.
"Hey, I need to go too. You need a hand in there?"
I could hear the giggle in her voice as she said it and I replied, "Give me just a minute."
"OK, Davey...a minute it is."
As I washed my hands I checked out the bulge in my shorts in the mirror. Fortunately, my dick was beginning to subside despite the delicious thoughts of Katie's ass rubbing against me running through my brain. Remembering Darci's ass wiggling against me too caused me to have to will my mind to focus on other things.
I opened the door to find Katie grinning at me. She stepped slightly aside to let me out.
"Everything okay, Davey?"
"Fine," I lied.
"OK," she mused as she brushed by me to enter the bathroom. Her hand accidentally on purpose brushed across the front of my shorts.
When I reentered the sitting area of the basement, Darci smiled at me from the couch. She sat Indian style with her long legs under her.
"Your turn," she said.
I took my turn and finished just as Katie returned. We each took several turns, but the mood of the game was more somber. After a few more rounds Darci asked Katie if she wanted to go swimming. My Dad had spent the better part of the last few days setting up an above-ground pool in the backyard. I'd helped him with some of the preparation of the ground underneath and some of the assembly. It wasn't fancy, like an in-ground pool would be, but it was practical and large enough for many people.
"I didn't bring a suit," Katie lamented.
"I might have something that will fit you," Darci claimed.
"How about you, Davey? Want to go for a swim?" Katie asked.
I looked at Darci to make sure I wasn't intruding on their time together, but she seemed content with me joining them.
"Sure," I said, immediately wondering if I'd left myself open for something more.
Everyone parted to get their suits on. Naturally, I was the first at the pool so I spent the first couple minutes skimming a few stray leaves off the top. I'd just finished when Katie and Darci appeared out the back door in bikinis. I tried to act busy and not stare, but stole several glances as they dropped towels on nearby lounge chairs and proceeded to the ladder. They looked hot in their tight fitting bikinis.
The water was cool, bordering on cold, not having hardly any time to warm yet in the early summer sun. I'd managed to get in to my waist only so far, with the top half of me still dry above the water. Katie and Darci climbed over the ladder only to be stopped by the first touch of the water. Katie was first and squealed at the cool water. Her reaction gave me reason to laugh and stare at her trying to descend the steps with Darci's urging.
"Hurry up, sissy," Darci accused.
"It's fuckin' cold," Katie protested.
I watched her sweet ass drop below the waterline. She bobbed up and down as she tried to get use to the water. Her movements made her tits wobble sexily in the top of the bikini, which looked a size or two too small for her already. I could definitely see the defined protrusion of her nipples against the thin fabric of the bikini top. Despite the coldness of the water, my cock began to react again.
Katie had made it far enough out of the way that Darci was able to descend the steps, but she stopped on the last step as the cold got her too. My gaze reluctantly shifted from Katie to watch my sister's long slender body finally drop off the last step. Her nipples poked out the front of her suit like erasers on pencils.
"Oh, geez, it's cold," Darci complained.
"I told you," Katie quipped despite her own shivering and bouncing around.
