The next day (Chapter 6)

Chapter 6: The Workout

You had scheduled the following day as a day off from work, which was easy considering you were one of the owners of the company. Of course, you still toyed with Tracy from home, using the vibrator app on your phone to bring her to the brink of orgasm repeatedly throughout the day. Thankfully, she managed to control herself and avoid any misfortunes. To start off your day, you decided to have a workout in your home gym, figuring you could use the cardio given how much fucking you'd been doing the past week or so and how much more you had planned. Come to think of it, Tracy could probably use some cardio herself given how exhausted she had been following the gangbang and even just having a train run on her yesterday. You were pretty much in full control of her life now, she was your sex **** and obeyed whatever command you gave her. However, looking around your gym, you saw the opportunity to be creative present itself. Perhaps you could provide her with a fun incentive to inject some enthusiasm into her workouts. Once you finished your own workout, you got to work, preparing a little surprise for your slut when she gets home.

When Tracy did finally arrived home, she walked into the kitchen to greet you, looking just as dishevelled as she usually did. Her yoga pants were drenched with her leaking juices as a result of the constant stimulation provided to her by the vibrator. Spotting you sitting at the table on your laptop, she lowered herself to her knees and crawled over to you, crawling under the table. There she unzipped your pants and fished out your cock whilst greeting you.

"Hello sir, how was your day off?"

"Pretty good thanks slut, I took some time to prepare a little surprise for you."

She gives you a look of surprise and contempt. "Have you finally thought of my punishment for cumming without permission?"

She had clearly had the thought of your punishment weighing on her mind ever since you told her about it. Perhaps that was greater torment than whatever you would actually end up deciding on for her. Or perhaps the masochistic slut was eager for whatever punishment she would be receiving.

You give her a light slap on the face. "You'll get your punishment when I tell you slut, now stop asking about it."

"Besides that's not what the surprise is. I'll show you once I finish replying to these emails."

Tracy was clearly unsettled by the anticipation, but nonetheless got to work sucking your cock whilst you finished up your work.

"Alright I'm done. Follow me." You say, getting out of your seat and exiting the room. Tracy crawls on her hands and knees like a good slut and stays close behind you. You finally enter into the home gym and reveal the labours of your day. It definitely wasn't much, but it would do the trick. Tracy's eyes open wide with surprise as she looks around the room, spotting the modifications you've made to some of the exercise equipment for her.

On the bike, you had removed the seat and replaced it with a dildo which she would be riding whilst she did cardio on there. On the treadmill you hadn't made any major changes that would get in your way, since you still planned on using it. Here you had wrapped some nipple clamps attached via a chain around the handles. On the squat rack there was now a massive 2 foot long dildo (with significant girth too) positioned on a low stool. Finally, you had placed an incline bench up against the wall which was one long mirror, with a suction cup dildo attached to the glass. Tracy was in complete awe with what you had done with the place.

"So I noticed you regularly losing your breath during some of our particularly intense group fuckings and I thought you could do with some cardio. You know, just to save you from passing out again when we inevitably have you being fucked by numerous men. And so I thought I'd make your workouts a little more interesting by modifying some of the exercise equipment."

Tracy seems to be in shock as she looks around at the various modifications you've made. She looks over at the ginormous dildo you have set up by the squat rack and visibly gulps, seeming to have an idea of the workout you have planned for her there.

"Anyway, I'll take you through each of the exercises you can perform in here but first, I'm gonna take you through some stretches." With that you move over to an exercise mat facing the big mirror on the wall and lie down. Tracy takes the hint and climbs on top of you in a reverse cowgirl position so that she's facing her own reflection in the mirror.

"Not quite slut." You say as you grab her legs from behind and pull her into a full nelson position, holding her legs up behind her head.

"Now put my cock in your ass whore." Tracy uses her free hands to line up your dick with her exposed asshole. Slowly pushing the tip in, you start slowly pistoning your cock in and out of her ass. You gradually begin building the pace until your practically slamming into her ass.

From this angle, your cock is pushing up into the roof of her ass which seems to be stimulating her G-spot because she's moaning like a common whore. Her moans get louder and louder as you begin to think she might be approaching an orgasm, which is further confirmed by her dripping pussy that you can see in the mirror.

"Of fuck. Please sir may I cum. Fuck fuck fuck! I'm begging you, please let me cu-uu-uuum!" Her begging seems to be on rhythm with your pounding of her ass.

"Alright slut, cum for me."

"Thank you sir! I live to serve! I live to serve! I live to seeeerve!" She screams out into the gym as she squirts all over the floor as a result of you rearranging her guts.

You continue fucking her hard in the ass from this position, also keeping to your word and giving her hips a decent stretch with the way you're holding her legs. Eventually, you can feel yourself coming to a climax and pull out of her ass. Tossing her to the side you stand up to give her your load. She recovers from your rough treatment and presents herself on her knees.

"I wanna cum on your tits slut." She's happy to help you make this happen and starts jerking your cock whilst aiming it at her breasts. You release your load all over her chest, plastering it in your jizz. Tracy goes to do her usual filthy behaviour and lick up your cum but before she can you interrupt her.

"No leave it for now, we'll keep it there during your workout as a reminder of why you're doing this, which of course is so that you can be a better cum receptacle." Tracy looks disappointed that she can't enjoy her salty treat right away, but does as you say and releases her tits, still covered in your cum. She turns her big beady eyes up to you wondering which exercise her workout will begin with.
