Erin put her hand on Courtney's leg, concentrating on the refreshing water in the hot tub bubbling around them. Both women were leaning back with their heads on plastic cushions. Courtney's leg slipped on top of Erin's, whose hand slid down Courtney's thigh and stopped just inches from her pussy.
Courtney spread her legs a few inches wider, anxiously awaiting the familiar feeling of her young friend's fingers. But Erin was in the mood to tease today. She moved her fingers past Courtney's pussy lips, past her clit and up her body until finding one of Courtney's small, firm breasts.
She let her hand rest softly on top of the breast, bending her fingers slightly to feel the wet skin mold to the shape of her fist. She felt the nipple harden against her palm.
Erin ran her fingers back and forth across the nipple. Courtney moaned as Erin finally began sliding her hand back down, closer to where Courtney truly wanted it. Rubbing her nipple always brought Courtney closer to cumming, but it was nothing compared to Erin's delicate fingers on her clit.
The lower the hand got, the higher Courtney's hips rose to meet it. By the time Erin reached the clit, her friend's body was almost above the water line. It was only after Erin made contact that Courtney let her body relax momentarily.
Erin rubbed slowly at first. She used long, unhurried strokes, pushing back the skin surrounding the little clit. When she felt it begin to grow, she sped up. Courtney pushed her body upwards toward the hand. Erin knew it wouldn't be long before her friend came.
Erin moved her hand down and inserted a finger into Courtney. It went deeper until hitting the soft, wet skin inside the woman's pussy. Erin fucked her with the finger for a minute before inserting a second finger. Courtney urged her to play with her clit some more, and Erin complied.
Little squeals of delight indicated to Erin that Courtney was on the verge of an orgasm. She rubbed for a few seconds, then stopped. Rubbed, and stopped. Finally, Courtney cried out and began to cum.
Erin put her entire palm over the clit and rubbed hard. She listened to the sounds of pleasure, finding the clit with her finger and pressing down on it some more. Erin's frantic motions excited Courtney and she thrust her hips out to meet the hand that was driving her wild.
A finger entered her again. Then two. Courtney fucked the hand and played with her own nipples, twirling them between her fingers. Just when she thought she was done, Courtney felt Erin's mouth on her breast. The moment the woman's tongue hit her nipple, a new orgasm began. Erin sucked hard on the breast, biting the skin just hard enough to stimulate her lover.
As the orgasm subsided, Erin rolled on top of Courtney and they kissed.
That was when Erin first noticed the figure standing just ten feet behind them.
"Andy! What are you doing here?"
The young man took a bite out of an apple. "Just watching."
Andy was ten years younger than his 31-year-old sister Erin, but acted just as mature in many ways. He was certainly mature physically, which Courtney quickly noticed as soon as Erin had slid off her and allowed her to turn towards the man.
Both women stayed up to their necks in the turbulent water while Courtney's beautiful grey eyes inspected Andy's muscular legs and upper body.
"I thought you were in school?" Erin asked.
Andy chewed away. "I'm a junior now, sis. Ends up we don't have a very busy schedule. It was a nice day so I wondered what you were doing." The glee in his eyes was unmistakable.
"You better not screw up in school," Erin scolded him in her best big sister voice.
"I won't. Are you going to introduce us?" he asked, nodding toward the naked Courtney.
"This is Courtney." Erin's tone lightened. "Her daughter goes to the same school as the kids."
"Hi," Andy said with a smile. Courtney acknowledged him, resting her chin on the top of her hands at the edge of the hot tub.
He grabbed a towel from the chair next to him. "Can I dry either of you off?"
"You can throw us those suits," Erin said, pointing to a small pile of bikini pieces close by.
"Ahhh. You're no fun." Andy threw the tops and bottoms into the center of the tub, just out of reach of the women.
"You bastard," Erin shouted.
He watched as they scooted through the water to retrieve their suits and awkwardly put them on. He had seen his sister many times before in her suit at the hot tub and pool. She was, indeed, very sexy. But he was equally impressed with her shorter friend, who seemed to be enjoying the game.
Andy found out, as they talked at a round, glass table shaded by a large umbrella on the patio, that Courtney was a 34 year old widow. She openly explained how her Marine husband was killed in the Middle East and how she and her daughter were coping. He was genuinely touched by the strength of the woman.
In the back of his mind, however, it was difficult to erase the scene he silently walked in on earlier. His sister, being married to a man fifteen years older than she, often seemed restless despite her considerable wealth. Perhaps Courtney would help, and Andy was all for that.
He stayed for lunch and his attraction for Erin's friend grew by the minute. Nothing was said about the encounter Andy witnessed, but it was never far from his mind. Particularly in light of his desire to find out if Courtney still...as she must once have...liked men.
Before the women changed into clothes to pick up their kids from school, they invited Andy back to the house the following Monday. He eagerly accepted and was told to bring his bathing suit. Courtney bit her tongue and refrained from suggesting he just swim naked as she and Erin were in the habit of doing.
Courtney spent most of the weekend thinking about Erin's brother and what he had seen and, especially, what she saw in him. She liked his apparent maturity, sense of humor, and body. In fact, she couldn't get his well-toned body off her mind. And was he as interested in her as he appeared to be? Or was she just imagining it?
Monday started out as another cloudless, hot day. Most of the last two months had been that way, so Erin's pool and hot tub were a real lifesaver to both of them. Their budding relationship centered around the patio and pool area during the day while the kids were in school. Erin's husband was seldom home even in the evenings. So they felt safe in the secluded surroundings of Erin's back yard to do what they pleased. No other homes overlooked the area and the women were topless or naked as much as, or more than, they were dressed.
Sex had become a routine part of their near daily visits. Courtney was a little shorter and less curvy than her younger friend, but both women were extremely attracted to the other. Andy would soon find out, however, that men were not totally out of the picture.
He arrived right on schedule and they took snacks out to the pool area. It didn't take long for Andy to tire of the women's chatter, so he headed for the water. Erin immediately noticed Courtney's inattention to what she was saying. Courtney seldom took her eyes off Erin's brother.
"Courtney, why don't you just get in the water...like you want to," Erin finally said.
"Not yet," Courtney replied. She never even looked at Erin as she said it.
"Then pay attention to me."
The tone of Erin's voice finally registered with her friend.
"Huh? Oh. I'm sorry." Courtney smiled sheepishly.
