Amy and Ron were lying on a double-wide chaise-lounge on their backyard patio when they heard the doorbell ring. They waited, motionless, his tongue lodged between the moist labia of his sister's vulva, while hers lips encircled the thick shaft of his erect penis. After a few moments, the doorbell rang again.
Amy reluctantly withdrew her brother's penis from her mouth.
"Shit!" she exclaimed. "Oh, well...I'll go get it."
She got up and grabbed a beach towel, wrapping it around her body as she headed into the house.
Opening the front door, she gasped in surprise when she found her friend, Nicole, standing there.
"Ohmygod! Nicole!" she cried. "I forgot all about having invited you over for a pool day, today, when our plans fell through for us, yesterday!"
"Oh? Did you make some other plans for today?" Nicole asked, noting the towel wrapped around her friend's body. "It looks like I just got you out of the shower."
"Oh, no!" Amy smiled. "My brother, Ron, and I were just out by the pool." A thrill ran up her spine as she thought about what she and her brother had just been doing a few moments before. However, being the polite and considerate young woman that she was, Amy quickly decided to forego her own pleasure and honor her invitation to her friend. "When I invited you over, yesterday, I didn't expect him to be around today, but if you don't mind, you can c'mon out and join us!
Nicole looked a bit hesitant. "Oh...uhhh...I don't know...I thought it would be just us girls. The bathing suit I wore is kind of...uhhhh..." she stammered.
"Oh, don't sweat it, Nickie," Amy encouraged her. "I'm sure it can't be any more revealing than what I'm wearing! C'mon," she said, taking her friend's hand, "I promise Ronnie won't be any bother."
She led Nicole through the house to the patio doors and called out, "Hey Ron, my friend, Nicole, is here!"
When they reached the pool she was relieved to see that Ron had a towel tied around his waist.
"Ronnie, this is my friend, Nicole. Nicole, my brother, Ron," she introduced.
Ron smiled warmly at the new girl and nodded hello, while she did the same, checking out the well-tanned young man lying on the lounge chair before her.
"Nicole's the girl I was supposed to spend the day with, yesterday," Amy explained. "I forgot all about inviting her over here for a pool day, today, when we found out her mom needed her yesterday."
"Forgetting something like that is quite understandable, considering everything that's been going on around here," Ron said, sounding satirical to the new girl, but actually being quite accurate.
"Oh, Ron!" Amy said, playfully punching her brother in the shoulder.
Amy turned to her friend and said, "Sit down and get comfortable, Nicole. The sun is really delightful this morning."
"Yes, it is," Nicole agreed, nervously fiddling with the buttons on the sundress she was wearing. As her eyes shifted back and forth between Amy and Ron, she finally managed to unbutton her dress and, hesitantly slipped it off.
"Oh, wow!" Ron murmured, barely audible, as he looked up at Nicole. The lovely young girl was a bit taller than Amy and just as slender and youthfully fit as his sister. Her breasts, covered by small triangles of brightly colored fabric, appeared to be slightly larger than Amy's, as well. The girl's pretty face was framed by long, light brown hair which fell past her shoulders. Her waist was long and slender, flaring to shapely, but not too broad, hips, and slender thighs. Low across those shapely hips stretched a thin strip of material, supporting another tiny triangle covering her crotch.
Nicole blushed at the boy's reaction and his penetrating gaze. She unsuccessfully tried to hide some of the considerable expanse of skin her tiny bikini left exposed and quickly sat down to hide her discomfort.
She muttered, "Uhhhh...I would have worn something a little more conservative if I'd known there were going to be more than just us girls here."
"Relax, Nicole, he's just my stupid brother!" Amy reassured her friend. "Besides, you look absolutely stunning!"
"I'll say!" Ron agreed. Nicole blushed again and squirmed nervously in her seat.
"Put your eyes back in your head, big boy!" Amy admonished, laughing as she punched Ron on the shoulder again.
"Well, I'm going to get us something to drink. Why don't you guys get to know each other?" Amy suggested.
When Amy returned with a tray of glasses and a pitcher of lemonade a few minutes later, Nicole seemed to have relaxed a bit, lying comfortably in the warm sun, no longer trying cover herself up. They were talking about what she was planning to do, following her recent graduation from high school. Amy poured everyone a drink, then pulled up a lawn chair and sat down, facing the other two.
As they talked, Nicole inquired about Ron's experiences with his first year in community college, Amy smiled in approval, thinking that Nicole and Ron seemed to be getting on well with each other. She noticed that her brother seemed to be getting an eyeful of the other girl's shapely, bikini-clad figure. Amy could discern a bit of a bulge in the front of the towel tied around his waist.
Gazing at the others as they talked, Amy's mind wandered, and images from Ron's magazine passed through her mind. In the pictures she imagined, however, the faces of the models were those of Ron and Nicole. And when she came to the set involving the two women and one man, Amy saw her own face on the second woman. She felt her juices trickling through her cunt-lips and she squirmed in her chair.
Finally, Amy stood up and announced, "Whew! I'm getting hot here in the sun. I'm going in for a swim."
As the others looked up at her, Amy untied the towel that was wrapped around her body and let it drop.
Nicole gasped and her eyes nearly popped out of her head as she saw her friend standing there before her, as well as her own brother, totally naked. Her mouth hanging open in shocked surprise, Nicole's eyes flashed back and forth between Amy and her brother. She was shocked, even more, by the lack of surprise on the boy's face. He just gazed calmly at his sister's naked body, nodding and smiling.
Amy tossed her towel onto her chair, turned, and, with a wiggle of her cute little ass and a flip of her long, blond hair, ran to the edge of the pool and dove in.
Nicole let out the breath she had been holding with a whoosh.
Ron glanced over at her and smiled at the look on her face.
She looked at him and gasped, "Amy just jumped into the pool, naked!"
"She sure did!" Ron replied. "That's one of the perks of having your own backyard pool."
