Lacy loved how it felt as she swam; slicing through the water gave her a feeling of freedom. That feeling was one of the few things that gave her an escape from everyday life.
Looking over, she saw Stacy and her brother in law Wes, talking and having some beers. She and Stacy were the last of their family and both women enjoyed it when Lacy visited. Stacy never got in the water anymore; her therapy for cancer just sapped all the energy out of her. Wes sometimes did.
Stacy could tell her husband was watching Lacy but couldn't really blame him. She hadn't really been able to take care of her husband's needs for some time. Plus her sister had a nice body and enjoyed showing off.
Wes had positioned himself so that he could see Lacy swimming. Stacy had her back to the pool. Wes pretended to listen to what his wife was saying but his attention was on his sister in law. Lacy was 5'5" with jet black hair and large hazel eyes. He figured that she didn't weigh much, maybe 100 pounds. She liked to wear a really skimpy bikini and her 32c breasts were practically hanging out.
Lacy got a thrill flirting with men. Every girl knows the look of lust men get and she liked giving it to them, but nothing else; to tease but never to please. She swam on her back and casually glanced over at her brother in law. Yeah he was staring at her breasts. Wes was pretty good looking. At 5'9" about 200 pounds and blond hair, her sister had done all right. She knew that Stacy was on a long road to recovery which left Wes unsatisfied. That didn't mean Lacy was above trying to give him an erection.
Lacy had a few guys she dated, but wasn't serious about any of them. She just used them for sex. Her brother in law was trying to hide that he was practically undressing her with his eyes. Lacy hoped that her sister didn't notice.
Being as he was staring at her chest anyway, she swam on her back to give him a good look. Lacy was an old hand at this game. Glancing over every now and again she would catch him leering and the expression of guilt he got always made her smile. Sometimes she would stop and just stand in the water facing him. She would play with her hair and absently rub her breasts. When he got the look that said he was about to explode, she would turn and swim away.
Wes was in a bad way and there was nothing that was going to help. He had always thought Lacy was hot. Before Stacy had gotten sick if he had been worked up, his wife would be there to take care of it. This wasn't the case now, he would be doing it himself later.
Finally Lacy got out of the pool and joined them at the table. The wind had come up so she took a seat in the sun to keep from getting a chill. She reached for the beer that Wes handed to her, making sure to push her chest out, "Thanks."
"You're welcome." His eyes had been drawn to her breasts again and he moaned under his breath.
Stacy was not feeling well and stood to leave, "Thanks for taking me tomorrow for my therapy."
Even though Lacy liked being a prick teaser, she really did love her sister. "That's okay sis, I don't mind."
"I need to lie down," and she walked away leaving her husband and sister.
As he watched his wife leave, Wes felt a pang of guilt for having lusted for her sister. "I'm glad you offered to take her, I'm all out of vacation time."
Lacy placed her hand gently on his, "I'm happy to help."
Wes felt electricity where she was touching him. Her towel had slipped showing her barely contained 32c's.
"Lacy stood up, "I guess I should go change and go on home. I'll be back in the morning to take her to therapy."
Wes waited for his sister in law to leave, and then headed for the bathroom. He needed relief before he went to bed. He and Stacy would watch television until they got tired.
--------
The next day Lacey drove her sister to the hospital. Stacy realized that she would be tied up all day. It was silly for her sister to just wait.
Stacy told her she would go home and that Stacy could call her to come back later. As she drove off, Lacy chuckled at her own joke. She hadn't said she would go to her own home.
She went to Stacy and Wes's home. She'd had a key made just for this reason and no one knew she had it. Parking in the driveway, she could barely wait until she was inside and took her clothes off. Once inside, she ripped all of her clothes off and headed for the pool. A sunny day, a pool and no one around was something she was going to take advantage of and no one would ever know.
------
Damn! Wes was pissed off. The city had a power outage and his work was affected. They exec's at work had determined to just close the plant until tomorrow and send everyone home. The trouble with that decision, Wes was hourly, and if he didn't work he didn't get paid. They had said that everyone could put in for vacation time to cover it, but he was all out.
-------
Lacy swam with nothing on. She just did laps and actually enjoyed herself more than when she had trying to show off for Wes. After several of those, she climbed out of the pool. She had brought her own towel, which was one of the reasons Wes and Stacy didn't know she came in when they were gone.
Stretching out on the towel she just relaxed in the sun, working on her tan. By the time they got home she would be long gone.
Even though he was still mad, Wes had spent the drive home trying to figure out what he could do so he wouldn't just waste his day. He saw her car long before he got to the driveway. "What the fuck is Lacy doing here?" Then he got worried. Was something wrong with his wife? He parked beside her car and ran into the house.
"Stacy?" He didn't get an answer. "Where are you?" As he hunted for her, he was getting more and more worried. Wes happened to look out the window of his bedroom and saw his sister in law lying by the pool with nothing on. He ran out to his back deck. "Where's Stacy? Is she all right?"
The warm sun had felt so good Lacy had fallen asleep, and woke up screaming. She saw her brother in law admiring her and scrambled to cover herself with the towel. "Stacy's at the hospital getting her therapy."
"How did you get in here?"
Lacy had to think quickly. "Ah - she gave me her key and told me I could swim until it was time to come and get her."
Wes knew that was bullshit, "Stacy gave you her key? Let me see them." His wife had a teddy bear key that Wes had given her as a gift. He knew she would never let it out of her sight.
Lacy knew she was caught. There was nothing to do but just tell the truth. "Oh, all right. I had a key made and sneak in here every now and then to swim, when I know I will be alone."
Besides being attracted to Lacy, Wes had a fantasy that he would catch his sister in law in a compromising situation and could use it to black mail her and fuck her. He walked over to her. "I think you should fucking leave," and he jerked the towel off of her.
Lacy screamed again and reacted by trying to cover herself. She grabbed the towel back, "That's mine."
Wes nodded and let go of the towel, but not before getting another good look. His sister in law was hot, her breasts were a nice and full, her nipples a dark pink. She kept her pubic hair trimmed, probably because of the bikini she wore. "You know that I have to tell Stacy about this."
"Yeah, I know." Her sister would never understand why she had broken into their house. "I guess she'll probably be pretty upset with me."
"Why didn't you just ask?"
"She would have said no. She hates the idea of anyone being in her home with her not there."
Wes already knew that about his wife and hadn't really expected an answer. He put one hand on the towel and gave a gentle tug. "You know," he paused for affect, "I don't have to tell her."
The first thought that ran through her brain was how could she let herself get into this? She got the message loud and clear as she felt him pulling at the towel again.
