One afternoon after work, Aaron sat in the waiting room of Phoenix children's hospital. Kristy had been volunteering there in the activities program, and her car was in the shop for a few days so Aaron volunteered to pick her up. After a few minutes of waiting, a grandmotherly receptionist eventually came in to talk to Aaron.
"Are you here for Kristy?"
"Yes, yes I am. Is she almost done with her time?"
"Yes, you can go in and see her," the older woman said with a warm smile. "You must be Aaron. Kristy's talked so much about you!"
"Oh, really? Positive comments, I hope," he laughed.
"Oh, of course, she thinks the world of you. I must say, Kristy is just the sweetest little thing, just adorable. She's so generous with her time, and all the kids love her to death. There was this one poor little girl who would just sit in the corner of the playroom and not talk to anyone, and we couldn't figure out how to get her to interact and play with the others, but Kristy got her to open up somehow. No idea how she did it, she just worked her magic somehow. You're a very lucky man."
Aaron was confused. "Lucky man? Oh, no, I'm not her boyfriend, I'm her..."
He paused. He didn't know what Kristy had been saying about him and the nature of their relationship, but it clearly gave this woman the impression they were dating, so revealing he was her stepbrother might cause some complications.
"...I'm her friend. Friend. We're just friends."
The woman had a chuckle at that. "Well, with the way she talks about you, I don't expect that to be the case for long. If I were you, son, I would lock that sweetheart up as soon as possible."
Aaron smiled at what the woman had said and considered his good fortune. He was guided toward the playroom, where Kristy was finishing up her volunteer work for the day. As he walked up and stood in the doorway, he saw Kristy lying on the floor, helping a little girl of about 4 or 5 color inside the lines of her coloring book as a few other kids played around them.
"And what animal is that a picture of, Violet?" Kristy asked as she pointed at a page in the book.
"Ellfum," the little girl responded as best she could.
"That's right! Elephant! You're so smart!" she said as the girl laughed happily.
Aaron laughed at this site before deciding to announce his presence. "Knock knock," he said.
Kristy popped up when she noticed him, and walked towards him to give him a hug.
"Hey Kristy, who is that guy? Is this your boooooooooooooooyfriend?" a slightly older girl of 9 or 10 teasingly asked as she laughed.
Kristy smiled and pointed at Aaron. "Oh, this guy? No, he's my personal driver. I get a personal driver because I'm very important, you see," she joked.
"That's right. Your car is ready, ma'am," Aaron laughed.
Kristy then addressed the group of kids in the room. "I'm going to have to go, kids. You all behave yourselves, okay?"
There were some protests as they all walked up to her individually and held their arms up so Kristy could pick them up and give them hugs.
"Hey now, don't be sad, I'll be back next week!"
Aaron was slightly apprehensive about kids, but it warmed his heart to see Kristy being so great with them and brightening their day. The two of them started to walk towards the entrance, but Kristy stopped him once they reached the ward with the older children's rooms. There was a boy of about 13 whose parents went to Pittsburgh and who was a big Panthers fan, who had asked if Kristy could get Aaron to sign a football for him, which he obliged.
The two of them then both left the hospital and drove back in his car, casually chatting. As they approached an exit on the freeway, Kristy turned to him.
"There's a business complex off this next exit that closes at five and is totally abandoned with no cars by seven," she smiled.
"Oh, really, now?" Aaron laughed. He quickly got into the rightmost land to make an exit and then followed her directions to said complex. He pulled into an area completely devoid of any other cars and parked in a spot in the corner.
"This area looks completely abandoned," Aaron smiled. "Why did you want me to pull over into here, miss?"
Kristy undid her seatbelt and then rubbed her hand over Aaron's crotch. "Oh, no real reason," she said as she reached her hand to stroke his crotch outside his pants while she leaned over to kiss the side of his face.
She leaned in to kiss his earlobe, and then he turned his face to meet her as their lips met and he swirled his tongue in her mouth. Eventually, she broke the kiss and then slowly slithered her way to the gap between the driver seat and the passenger seat to crawl into the back of the car.
Kristy got stuck in between the seats for a moment as she tried to crawl through, with her shapely ass sticking up in the air, on display in her tight jeans.
Aaron gazed upon her and then used his left hand to give her ass a light and playful slap.
"Ow!" she said playfully as she crawled through and readjusted herself to lie sideways on the backseat. "Why did you just slap my ass? That's gross. You're my big brother, you're not supposed to slap your little sister's ass, you pervert! Keep your hands to yourself!"
He laughed and then got up out of the front seat of the car, walked around to pull both front seats as far forward as possible, then opened the back seat to join her. He crawled down to lay on top of her, then grabbed the back of her head and continued to kiss her as he slid his finger down the front of her pants to stick his finger in her.
Aaron knew that he had never felt anything like this before for any girl that he had been with. Not even Jessica, who at one point he was convinced he would spend the rest of his life with when they were in high school. He had broken it off with her eventually for reasons that he never fully understood, just because he eventually felt that there wasn't any romantic spark. He had sometimes thought back to that decision and regretted it, not sure if that was his best shot at love and he squandered it.
But now that he was with Kristy, he knew. Kristy was everything he had been looking for. She was so compassionate, so loving, the person he felt he could finally be himself with. It was a damn shame that she was his stepsister and they couldn't full embrace being lovers in public, but he figured they could work around that and that people would eventually understand.
Kristy reached down to grab his belt and started to pull it off. He knew that he could be in for another relatively mindless fuck session, but he decided to take a risk and make his feelings known, at least vaguely.
"Listen, Kris, before we start this, for this time at least, I had something I want to ask you..."
"It's not about asking me to stop calling you big brother again, is it?" she smiled. "I think we've both firmly established that won't happen."
"No, it's not that," he sighed. He did want her to stop calling him that, but he had sort of gotten used to it and knew it was a lost cause. "It's just that..."
