- Hey honey, what is the plan for tomorrow?
- Hmmmm, we are meeting Laura and her kids in the afternoon, and that's about it. May need to do some shopping in the morning for lunch. Why?
- Was thinking we could check if there is any gym around to go for a quick workout, been at your parents for almost a week and haven't done too much.
- Ah yeah cool, let's check something later!
Rachel and Mark lived far from her family, and so once or twice a year they set some time apart to go and visit them for a week or so. Rachel's parents lived in the north, the weather in the winter months was cold and harsh if you were not used to it. Rachel and Mark lived in the south though, were winters were mild and there was still plenty of sun.
That night, before heading to bed, they checked and found a gym in a nearby town. After talking to her parents to see what their plans were, they decided that they would head out after having some breakfast, so then they would be back home for lunch with family.
- Rach, did you see my gym shorts? Can't find them.
- Yeah, they are in the suitcase, under my staff -she replied from the shower.
Mark walked towards the suitcase, and could not help but have a look at Rach while she was showering. She was shaving her legs getting ready for the day after. He stared at her for a bit longer thinking of how hot she was, and then pulled himself together and grabbed the suitcase. While he was looking for his shorts, he saw some of her underwear, and noticed a tiny black thong he especially liked on her. He took it out and left it on top of the bed clothes she had prepared to wear after the shower. He then headed back to the room and sorted everything for the day after. Once done, he laid in bed reading a book he got hooked with a few days ago. A few minutes later, Rachel came to the room. He looked up and saw her wearing a long wide t-shirt and smiling.
- What you smiling about?
- You like that one, don't you?!
- What do you mean?
Rachel walked towards the bed and before getting in, she pulled her t-shirt out and turned around, letting Mark see that thong on her while smiling. He put the book down, and smiled back at her.
- I do like that thong, especially when you are wearing it...
Rachel crawled into bed and went up to him. They started kissing while he was sliding his hands all over her body, until he reached her ass and grabbed it firmly. She looked at him with a playful look, and slowly worked her way down to his cock. He was already hard when she took it all in, and did not take long for him to finish in her mouth. She went up to him and kissed him with a smile and her mouth still dripping some of his cum.
- That was quick baby!
- Yeah... Been a few days since the last time we fucked, and when I see you on that thong I can't help it.
He grabbed her gently and turned her around, so she ended up sitting on his lap both facing towards the wall. Mark started kissing her on the neck while touching her body gently. Her boobs were small but firm, and reacted to his touch getting even firmer. He kept one hand playing with her nipples, while moving the other one down until he reached her pussy. When he slipped his hand under the thong, she gasped slightly and arched her back letting him comfortably massage her clit. She did not say anything before, but she could also feel the lack of sex of the recent days due to the trip, and how as days passed by, she was feeling hornier and hornier. As he felt that her breathing was becoming more and more agitated, he picked up the pace with his fingers massaging her clit, but when he felt she was close to the orgasm he stopped.
- Why would you do that?!
Mark smiled and kissed her without saying anything.
- Mark! Why would you do that -Rachel said with a tone of anger in her voice.
- I got something in mind baby, I know you wanted to cum badly, but I thought you could hold it for today, and...
- And..?!?!
- Tomorrow in the gym... Maybe we can play a bit around, you know... There will surely be sexy people over there, so we can have some fun..
- Hmmmm... -Rachel was still not fully convinced, but the thought of what Mark was mentioning turned her on as well.
They both laid next to each other, and before falling asleep, each one fantasized about the next day. Didn't take long, as both of them were pretty tired, before they fell deep in their sleeps.
The morning after some neighbours unexpectedly came to have a coffee together, so they did not even have time to talk about what had happened last night. They got up, quickly dressed up and headed to the kitchen to meet with the others. After some chattering and some nice breakfast, the neighbours left, and Rachel and Mark made themselves ready before heading to town.
- Hey Rach, you got everything in the sports bag?
- Yeah, I packed it all don't worry, even this... -and she looked at him naughtily while slightly pulling her tight gym shorts down and letting him see the same thong she was wearing last night.
- Hahahaha, you dirty fucker, I love it! -Mark said while kissing her and giving her a soft spank in her ass.
Once they got to the gym, they signed up for a day pass, made themselves ready in the changing rooms, and went to the main room to start their workout.
- So I think I'm going to warm up a bit in the treadmill -Mark said
- Yeah me too, let's go!
They headed together to the cardio area of the room. There were plenty of treadmills, so they picked two empty ones and started some soft jogging. The treadmills were in one side of the room, so from there they had a pretty good overview of the rest of the room and the people. It was not packed, as it was a weekday, but there was a fair amount of people working out. After warming up for a bit, they headed to the machines area.
- Alright, I think I am done with the treadmill, gonna go and do some legs.
- Yeah you go, I will do some upper body. Make sure you show around that nice thong... -Mark said playfully while kissing Rachel and biting her gently in her lip
- Yes sir! -she replied while kissing him back and purposely grabbing his cock with her hand for a second
Rachel headed to the leg machines area, and after having a look around she picked up one and started working out. While resting in between sets, she had a look around. There are some pretty hot guys over here, she said to herself while smiling. She noticed that not cumming the previous night had been annoying, but at the same time the horniness had carried over to that moment, and along with the comments from Mark, she started to feel aroused. While caught in those thoughts, and about to start with a new machine, a guy came close to her.
- Hey sorry, do you mind if I jump in that machine while you are resting?
- Sure! Let me do my first set and then you can jump in.
- Sweet, thanks.
Rachel noticed that even though she had been working out for a while in the gym, that machine that she picked up was a bit different to the ones she was used to, so it took her a bit to adjust it and get the movement right. Once she was done with her set, she smiled, picked her towel and stepped aside.
- All yours, even though I'm not really sure I have done too well! - she said while laughing
- Yeah.. I did not want to say anything, but now that you mentioned it, you need to make sure your hips are aligned while pushing back, otherwise you can hurt yourself. Let me show you!
Rachel observed how the guy set up the machine, and how effortlessly he made it look when doing his set. While he was at it, she had a proper look at him and noticed how hot he was. Before she had time to stop staring, he turned and kind of caught her. She immediately blushed and started mumbling some nonsense about his hips position. He smiled and asked her to go back to the machine so he could help her with the next set until she got it right.
- Alright, so hold those two bars with your hands to make sure your body is still, face forward with your hips, and now push back with your right leg. Do not load the machine too much until you get the movement right.
- OK, let me try that - Rachel said still feeling a bit nervous
- Much better, but do you mind if I adjust your hips a bit?
- Yeah of course, go ahead.
As the guy got closer and gently grabbed her hips to adjust them, Rachel noticed how nice and warm his hands were. She started pushing back again, but could not let go the feeling of his hands on her waist. While working on the set, she noticed how wet she was getting, and that turned her on even more.
- There you go, much better! -he said
- Yeah, by the time I get it right it will be the last time I use this machine!
