It was with a sense of foreboding that I opened the instructions from my Mistress. She had promised a “fun” day, but I knew that the fun might be mostly hers, not mine!

“Slut, you need to get in shape. You are in desperate need of a trip to the gym.”

Well, that’s not too bad, surely. I nice bit of a workout. Looking at the fellow gym members. There might be some pretty girls, in their sexy gym wear. Could be fun!

“But, we don’t want you to be too comfortable now, do we?”

Oh, oh!

“So, to get to the gym, you need to be wearing panties, pantyhose, and your cage. When you get there, change into your gym wear, that I have packed into your bag. Keep your panties, pantyhose and cage on.”

Oh dear, I dread to think.

“You are then to work out. 45 mins of cardio, and some weights. You can choose the order – choose wisely”

What could that mean? Why do I need to choose wisely?

“Make sure you are well hydrated – your bottle is in the bag.”

Well, at least Mistress is making sure I am kept healthy!

“After your workout, you need to cool down in the pool. So, back to the changing rooms, change into your swimwear I have packed, at least 10 lengths, and then back to change for the way home.”

This is not looking good.

I get changed ready to leave – panties, pantyhose, cage, and cover it all with my normal male clothes. The gym is fairly empty when I get there, there is no-one in the changing rooms. I open the bag. There is my water bottle – pink! There is my towel – pink! And, there is my workout gear. A sports bra. A fairly tight T Shirt, and a choice of bottoms – capri length leggings or cycle shorts. I’ve got to leave my pantyhose on though! So, either show them off in shorts, or wear really feminine leggings! Shorts. Perhaps if anyone sees me they will think they are compression tights? I quickly don my sports bra and T-shirt.

I decide to do the weights first. (The correct choice – after my cardio, my sweat made the bra stand out like a beacon – at least I could hurry back to the changing room, and not suffer the gazes of everyone in the weights area!). There are only a couple of others in the gym. I am sure their stares are on my legs. Why is that guy wearing pantyhose in the gym? I hurry through my repetitions.

I need a drink – but my bottle is so obvious! I need to towel down – but my towel is so obvious! At least I have my cage, so I can’t get erect!

Onto the cardio. 45 mins on a treadmill. I choose one in a quiet area, and get started. Hill climb for 45 mins. It starts fairly easy. I calm down a bit and relax into the run. Then it starts to climb, exertion up. Sweat starts to build. I glance in the mirror – is that a silhouette of my bra I can start to see? Oh no, I am only half way through. Someone takes the treadmill right next to me. There is someone right behind me. They will be able to see my back. It must be obvious. Arrrgggghhh!

I hurry off after I finish. It’s over.

But then I remember – I have to swim.

What on earth has my mistress packed? There is a choice again. A one piece! No! Or, bikini bottoms. No! Err, no male swimmers in here? No! It has to be the bikinis. I try to rush to the pool. I nearly fall. I get in the water. Partially hidden at least! There is no-one else here. Perhaps I can get this done before getting spotted? Six lengths in and a beautiful girl comes to the pool. Again, thankful for my cage! Ten. Done. Now, to escape. I gingerly get out of the pool when she is heading the other way. I rush to the change room.

No-one there! Quickly dry, dress and leave. But, what is this, at the bottom of the bag is my clothes for the journey home. Panties, hose, bra, shaper, female jeans, and a feminine style T-shirt.

So, I had done everything in the gym, and now I had even more to do just to get home! I thought this was supposed to be a fun day! Well, maybe it was!
