I had to go out of town for a conference for a couple of nights and that meant that I would miss our mid week workout. My wife and I had started going to the gym three days a week and it was really making a difference. I figured she would still go to the gym Wednesday morning without me and our trainer would still work her out. I was surprised when I called her Wednesday afternoon on one of the breaks and she said that she didn't go. I gave her a little bit of guff, but nothing serious.

When I got home on Thursday afternoon, she was moving pretty slowly. I asked why and she said, "You guilted me into going to the gym last night and I had another crazy workout."

"Oh, did you schedule it with Hector, our trainer?"

"No, I went in late at night again and worked myself out. Well, that's not exactly true."

"What do you mean? Did you have another late night workout with some make believe men to give me another fantasy? Let's hear it."

She knows that I don't have a problem with her having sex with strangers. We've been married for a long time and we both agreed that if we could have sex, to go ahead. And while I've had my share, she always seems to come up with more outrageous tales. I don't even know if they are true, but they are always hot.

"I went in around 9:30 and there was a younger girl, pretty hot, just heading out."

She said she was expecting some friends of hers to work out with her as they know what to do, but they didn't show so she was heading out. She had a great ass and was actually similar looking to me, just quite a bit younger.

I was wearing tight shorts, like volleyball shorts, and just my sports bra. It was kind of warm out so I didn't need anything else and I wasn't expecting anyone else in the gym. The shorts did a real nice job of highlighting my ass and rode up as I started to work out revealing a lot of cheek as I walked around the gym alone.

I got to the leg curl machine to work my glutes and hammies. I put my ear buds in and laid down with my legs ready to start the curling motion to work my hamstrings. As I said, my shorts had kept creeping up my cheeks and I just got tired of pulling them down, and because there was no one else in the gym, I just left them up leaving most of my ass exposed.

After about my third hamstring curl, I felt a smack on my left ass cheek and then immediately a smack on my right ass cheek. Not painful, but definitely surprised me and as I looked up, I saw two guys walking deeper into the gym carrying their duffle bags. I got up on my knees on the bench and then a third smack on my exposed ass as a third guy walked past and didn't say anything.

I took my earbuds out and yelled out to them, "Hey, what the hell!?"

The first two guys had already turned the corner going into another part of the gym and the third guy spun around and looked at me and got a look of horror on his face. Just then the first two guys came back around the corner and got the same look on their faces.

"What the hell was that about!? Do you guys just always walk in and smack random women on their asses?"

One of the guys spoke up, "Holy shit, I'm, we're so sorry. We were supposed to meet our friend Jaz here and we all thought you were her. She was going to work out with us and you looked just like her. She usually wears that type of attire and we thought you were her. I'm really sorry about that."

"Are you talking about that little hottie who left about thirty minutes ago?"

"Yeah. She's a cheerleader at the local university that we go to. She wanted us to work out her lower body and tone her up a little bit. We're on the football team."

It was at this point that I noticed that these three guys were pretty big and very much in shape. Two guys were white and one guy was black.

"Well, you should make sure before you go smacking someone on the ass. Wait. Are you trying to tell me that my ass looks like that of a college cheerleader?" My ego got the better of me and I couldn't help but feel proud at that point. Now I was curious as to where this would go.

"Well, the way you were laying and doing those hammie curls, yeah. But, you know, we would need to see you do some more exercises to make a for sure decision. Want us to work you over like we were going to do with Jaz?"

Like I said, my ego was in full blown go mode at this point. "Well, I am here to get a workout and you guys look like you could do that." They got the hint as they all smiled at each other.

"Alright. First thing we should do is squats. That will get a good start on your glutes and quads. Let's head over to the squat rack. We prefer free weights for this. When you're trying to tone instead of bulk, you use light weights and lots of reps."

They showed me where to stand and then the biggest guy moved in behind me and said, "I'll stand behind you and show you what movements you should do to get the most out of the workout."

He stepped in closer and I could feel his cock pressing on my ass. Actually, it was probably a little higher up and pressing on my back, but I could definitely tell it was his cock. As I lowered down into a squat, he squatted with me and if he wasn't wearing shorts, his cock would have definitely rubbed all over my back. I'm pretty sure he wanted me to feel it.

"Good, now let's do 14 more reps and then we can move to the next exercise."

By the time I finished that set, I was getting hot, and not just sweaty. His cock rubbing all over me had gotten me worked up. I knew where this night was going. My shorts were totally running up my ass from the workout, almost like a thong. I didn't bother to fix it as I thought I would start giving them a better show.

The next guy had the next exercise set up. It was back to the leg curl machine. I laid down on my stomach and put my legs under the bar and got ready for curling. As I started, he touched my ass on both cheeks and then ran his hands down my hamstrings and said, "See, you should feel this exercise in both ass cheeks and hamstrings." He kept going from my ass cheeks and hamstrings, massaging and rubbing them as I went. Several times he slid his hands between my thighs and said, "you want to make sure you keep your legs spread just a bit, it will give you a better workout." After 15 reps he had me stop. I was really getting worked up at this point and was now actually sweating too.

The third guy had what appeared to be some sort of agility station. It looked like a ladder laid down on the ground. He said, "now, I want you to do this as fast as you can. Put one foot inside the rung and then the other. Then take the first foot and move it out and up to the outside of the next rung and do the same with the other foot then. Work your way all the way up and then turn around and go back. Then one more trip to the end. This will really work everything while increasing your quickness."

I did as he told me to and realized that my ass was jiggling all over the place and my tits, even though they were in a sports bra, were bouncing quite a bit too. All three watched as I did the station and were enthralled by the bouncing and jiggling.

When I finished, he hustled me across the gym to another station that had just a small bar about eight inches off the ground. "Now, I want you to jump with both feet together from side to side over the bar. Like this," and he showed me how to do it.

Again, bouncing and jiggling and they were watching the whole thing play out. As I finished up, he said, "come over here to the bench press station and I will stretch you out. It is always good to stretch after each circuit."

I laid down on the bench and he said to scoot to the end so my ass was right at the edge and to lift my legs up. I scooched down and lifted my legs and he stepped in close and grabbed one in each hand and spread them far apart. He then started to push them up towards my head, really stretching my hamstrings. As he did this, he moved close enough that his cock was rubbing directly on my outer lips. He kept gradually pushing my legs further and rubbing a little bit harder, which was driving me nuts. He was rubbing his cock up and down my thinly covered pussy with each time he stretched me. I know he was enjoying himself as I could see his cock was erect in his gym shorts. This was fine by me as I was really worked up at this point.

He then released my legs and I was able to stand up. They got together and the guy who had the last station said, "Well. We can't tell for sure if your ass is as good as a college cheerleaders even though we ran you through one circuit of training. There's just too much material in the way for us to truly see how your muscles are moving."

I responded, "Oh, me having them riding up my ass isn't showing you enough to make a decision, huh?"

"Well. Yeah. See, we've seen Jaz's ass and we can't truly compare you to her with anything on, now can we?"

"So, you want me to go bottomless for the next circuit? Is that what you're asking me, you know, just to make a fair comparison?"

"Actually, you should probably take your top off too if you really want us to make a fair comparison. Jaz usually works out naked with us."

"Really? And what about you guys? If I'm gonna be naked, I suggest you guys drop your clothes too. It wouldn't be fair for only me to be naked, now would it? Besides, who knows, maybe you will come up with some different exercises that might be more..."

"Fun for both parties?" he said as he finished my sentence.

"Yes, fun is the word I was looking for," I said as I started to pull my sports bra up and over my head and then moved to my shorts and removed them as well.

They didn't hesitate and when I looked back up, I had three nice hard young cocks standing at attention for me.

"Well, it looks like you boys are ready for the next circuit, I see."

The black guy laid down on the bench for the bench press and said, "come over here and straddle me. This circuit we will do a little more isometric workout. Why don't you guys grab the leg squat bar and remove the weights."

As I straddled him, I could feel his cock slide up between my ass cheeks. Not penetrating me, but sliding easily between my cheeks.

"Now, I want you to hold the bar on your shoulders and do slow up and downs with little weight. You won't be able to go down all the way, which will actually work your legs more than a full squat."

As I did the first few, his cock slid up and down rubbing my anus. It was driving me nuts. "What if I were to put your cock in me while I did this? Would that give me a better workout? Why don't you hold it up so I can see if it will go in."

When I stood up, he lifted his cock straight up for me and I could feel the head of it lined up perfectly. As I lowered myself down for the next rep, he easily entered me and was able to release his hand from it. I couldn't go down as far because it was so big and he let out a nice moan. After several more reps, I was able to lower myself almost all the way onto it and he was starting to push up. We developed a nice pace and I was really getting in to it. Sliding up and down on this young studs cock was driving me towards an orgasm.

Still holding the bar across my shoulders, leaving my tits completely exposed, I told him to play with my nipples. He didn't waste any time and started to pinch, tweak, twist and pull on my nipples. It didn't take me long to get over the top and have my first orgasm of the night. As I was still riding his cock and riding the waves of my orgasm, he pushed in as far as he could and started to unload his cum deep inside me. When we both finally calmed down, my legs were like jello and I don't know how many reps I actually did.

The next guy, had me line up next to the ladder on the floor again. "You know the drill, get to it."

As I started doing the ladder drill, my tits jiggling and ass wiggling, the other two guys were on each side of me smacking me on the ass driving me to go faster. When I was done, my ass was bright red and stinging like a mother. "Good, now get over to the low bar and do the hop drill."

As I walked over to the next station, I could see them in the mirror following me with their two hard cocks bobbing and bouncing behind me. As I started to hop over the bar, they both stood in front of me and watched my tits bounce all over. They were truly enthralled watching me.

After ten hops, I stopped and said, "that's all I can do," as I was standing there huffing and puffing.

"Okay, head on over to the massage table and we'll stretch you out one last time."

He positioned me across the massage table bent over. Without warning, he stepped in behind me and slid his cock right in and pushed to the hilt. it caught me by surprise and I opened my mouth to say something, and the other guy had stepped in front of me and took the opportunity and stuck his cock right in my mouth. I had no choice but take it.

The guy who was fucking me from behind said something to the black guy, I couldn't hear what he said, but then he addressed me. "Jaz loves when we work out like this. Make sure to give that cock in your mouth a good blow job and make sure you swallow. I know you are married and probably don't do that anymore, but Tom isn't pulling out, so you might as well accept it."

I was so into it at this point, I moaned my acceptance and started to suck and lick that cock for all I was worth. I was so into it that I didn't feel the baby oil being applied to my anus until I felt him pull his cock out of my pussy and slide it up and push in to my ass.

He started to fuck my ass while I was sucking off his friend. "The only true way for me to know if your ass is as good as Jaz's is for me to cum in it, just like I do with her. So, you're going to swallow Tom's load and I'm going to cum in your ass. You probably don't even let your husband do that anymore, do you?"

He didn't let me answer as he didn't care what the answer was. He started to really pound my ass faster and faster until he was fucking it at a fevered pitch. He finally pushed in all the way and held his cock inside of my ass as far as he could as he started to shoot his cum inside my ass. As I felt him shooting his load, Tom pulled my head all the down on to his cock and shot his load down my throat. He was so deep that I didn't even have to work at swallowing it, it just went down. Thinking about taking a stranger in my ass and swallowing another strangers load was all I needed to push me over for my second orgasm of the night.

As the three of us were riding the waves of our orgasms to completion, the guy in my ass said "Yep, your ass is every bit as good as Jaz's. So, I would have to say that you have the ass of a college cheerleader."

Tom pulled his cock out of my mouth and I licked it clean for him and then the other guy pulled out of my ass. I was whooped. Having done a really good workout and getting fucked like I did, I just laid on the massage table while they got dressed and left. I finally recovered and used many wipes to clean up the mess and the equipment.

Julie looked over at me and said, "I can tell by your massive erection that you found my little tale entertaining. But, I'm too sore to help you right now. I suppose I could give you a hand job, but everything else hurts."

"Julie, I'm not sure if you really did that or not, but that was quite the story. It definitely got me wound up."

Just then she got a text. She looked at it and actually kind of blushed a little as she read it. She typed a response and had a grin like a chesire cat.

"Who was that?"

"Oh, that was Walter, the owner of the gym."

"Walter? What did he want?"

"Oh, he said that he was watching the newly installed security cameras from the gym and noticed that I had worked out last night. He said that some of the things I did were very interesting and if I wanted another late night workout that he could put together a group for me to work out with in the future."
