"Oh my God, Gail, this is amazing," said Amber as she walked around the machine.
"I know; we decided to go a little extra in the budget for this," replied Gail.
"A little extra. I know this machine; it's top-of-the-line. You must've maxed out a couple of credit cards for this."
"Close enough," Mitch joked.
Amber was joking, but Gail understood why. She and her fiancé went all out on their at-home gym, getting the latest and most expensive equipment.
They had a spare room in their house, which they turned into a small gym. Besides the treadmill, they had also gotten a decent-sized workout bench, a good series of weights, and a wall-mounted flat-screen TV so they could watch TV as they worked out.
"She looks just as surprised as you were when we got his machine," said Mitch. "I mean, she looks exactly like--"
"Sweetie, I get it," said Gail. "We talked about those twin jokes. Either be more original about it or don't make any jokes at all."
Gail and Amber were identical twin sisters. They didn't mind twin jokes; they were used to hearing them their whole lives and often made jokes about it themselves. But Gail had to draw the line at some of the more obvious and clichéd ones. Mitch sometimes made some good twin jokes that would make Gail laugh, but many of them fell flat. The one twin joke that always made Gail laugh was how Mitch knew what her sister looked like naked.
"I'm so jealous of you right now," said Amber.
"You know, you can use this whenever you want," said Gail.
"I can?" Amber asked ecstatically.
"She can?" Mitch asked, worryingly.
"Why not? It would be better than having to pay a big membership fee at the gym," Gail replied.
"No, I can't do that," said Amber. "Your house is too far away for me to come here three or four times a week."
Mitch felt relieved when she said that. He liked Gail's sister but couldn't handle it if she were around more often. Whenever they get together, they act like sorority girls, and it can sometimes be too much for him to handle.
"Well, if you ever do need to use this equipment, you're free to come by anytime," said Gail.
"Thank you," said Amber.
TWO WEEKS LATER LATER
It didn't take long before Amber had to take Gail up on her offer. Her gym had to be shut down for a week for maintenance issues. She uses one of the big-name chain gyms, and her membership did allow her to go to any other gym locations, but the closest one was another 50 minutes away. If she lived in a metropolitan city, they would be everywhere, but in the suburbs outside those cities, they're scarce.
Since Gail's house was only 20 minutes away, she asked to use it for a week until her gym reopened. Gail gave Amber a spare key and the security code to turn off the alarm so she could come and go from the house easily whenever she wanted.
Gail's gym didn't have everything that Amber's gym had, but she still managed to fulfill her usual workout routine. Thanks to the workout regimen that her fitness instructor helped her develop, she had a great physique as a result.
She didn't mind using a smaller gym set, but the only thing she missed about her own gym that she couldn't have here was all the cute guys she could look at while she worked out. She felt it kind of helped her get motivated to watch all those men, some of them with big muscular bodies, working up a sweat. It was a common thing in gyms, with men and women checking each other's bodies as they worked out. It was good for motivation, and all the hormones pumping in their bodies made them exercise more. It was also the reason why Amber had a few good hookups over the years at the gym, including a few times with her own fitness instructor.
She kind of wished Mitch was around to workout with her. She always thought he was a good-looking guy with a great body. She had seen him workout at the gym the few times he joined Gail when they worked out together. He was no bodybuilder, but he had good muscle tone. She had seen him at the beach too, without a shirt, and couldn't help thinking how sexy he was. Just thinking about his body was making her run faster on the treadmill.
She would sometimes joke with Gail that one day she would pretend to be her just to get into bed with him and see how well he could fuck her. Gail would punch her in the arm and start laughing at her.
Although, it wouldn't be the first time they pretended to be each other to fuck a guy. Several times back in college, they switched up to sleeping with each other's boyfriends. They only did it with guys they weren't serious about and were going to break up with anyway; never with someone either of them really liked. There were a few occasions when the guy figured out that they had slept with the sister. Not surprisingly, they weren't mad about it because they got laid and they got to brag about it to their friends.
Amber and Gail had a lot of fun back in college with the sexy twins' gimmick, which made them very promiscuous back then. There were a few times when they shared the same guy for a threesome. And a few other times, they brought two guys to bed with them, who would switch between the sisters or double-team one sister while the other watched. The sisters never did anything with each other, of course, no matter how much the guys asked them to. But they did grab each other's tits once in a while, just to titillate them.
Then Gail met Mitch after college, and they got serious with each other very fast. Amber wanted to suggest a threesome with Mitch, but after seeing how head-over-heels Gail was in love with him, she decided not to suggest anything that could ruin her relationship with him.
After Amber finished her workout, she wiped down the equipment she used. She worked up a big sweat and was in desperate need of a shower. She realized there was an added benefit to using Gail's gym set; afterwards, she could take a shower here where she knew Gail had the same shampoo and soap she also likes to use.
After the shower, she wiped herself down and took a good look at herself in the mirror. She wasn't a conceited person, but she loved how great she looked for a woman who had just turned thirty.
Her hair was still very wet, so she wrapped it with a towel to help dry it better. She realized she left her clothes in the gym bag in the master bedroom. That's where she went first when she entered Gail's house, to change into her workout clothes.
She left the bathroom completely naked, except for the towel wrapped around her hair, thinking it would be OK since no one else was home. She went to the bedroom and was about to put on her clothes before she thought about raiding her sister's closet for something new to wear. She knew Gail wouldn't mind; they did this with each other all the time. Gail would sometimes go to her apartment and raid her closet when she wasn't home either.
She pulled out a nice top and jeans and was ready to get dressed when the bedroom door flung open and she saw Mitch enter the room. She was in such shock to see him there while she was completely naked that she couldn't say anything or move at all.
"Hey babe, I didn't expect you to be home," said Mitch, before going to his own closet on the other side of the room.
At that moment, Amber realized that Mitch thought she was Gail, so she went with it.
"Oh, yeah, I got home early," said Amber.
"You had a good workout, I see," said Mitch.
"Oh, yeah... it was intense," she replied nervously. "What are you doing home so early?"
