"You're late. Get undressed and get in your position. Quickly, now."
I did as I was told, taking off and carefully folding each article of clothing before placing them in a neat pile on the floor. When I was fully nude I got down on all fours with my back arched.
"Oh, don't forget your butt plug!"
I got my plug from my bag and applied the lube. I began inserting it.
"On your knees, so I can see."
I turned around and got back on all fours, with my ass in the air and my legs spread to give her a nice view of my asshole. I took the plug and teased it in and out, spreading the lube and stretching my hole.
"Take your time, don't hurt yourself," she said as she reached between my legs and grabbed my balls, massaging them gently. Quickly she moved to my dangling, hard cock and stroked it, first slowly, then quickly. "I'm just milking you like a cow aren't I?" she quipped. "Remember not to cum."
It felt so good to have my hole being stretched at the same time as I was being milked and I soon felt the pre-cum leaking out involuntarily. The butt plug slid all the way in.
"Good boy!" she said as she slapped me on the ass, which was quickly followed by an "ew." I looked up and saw that she had gotten lube all over her hand. She washed her hands in the bathroom as I silently chuckled.
"Now, for your tardiness I've decided it's time to use a new tool on you."
She picked up a small, wooden crab mallet off of the bed. I immediately knew how she was going to use it and I tensed in anticipation. "Stay still," she ordered, "or it will be much worse for you."
She gently tapped my right testicle with the mallet. It didn't hurt too bad and I let out a silent sigh of relief. Then she hit with the exact same velocity in a spot less then two centimeters away and my body jolted with pain.
"I told you to stay still!"
She repeated this on the left side. With each hit I flinched, but slightly less than the time before.
"We can keep doing this all day if we have to, until you learn how to stay still."
I was seriously doubting whether that was possible. With each new hit my body instinctively moved away from the mallet. As if there was a direct line from my balls to my nervous system. Wait, there probably was, right? I never did take an anatomy class in school. Eventually she gave up on it and rewarded me by milking my cock again. She ordered me to look in the mirror to watch myself get milked like the animal I was. The feeling of her fingers, with their tight grip on my shaft's skin, gliding over the head and back down again was intoxicating. Each finger on each stroke brought me closer and closer to ecstasy.
"No cumming!" she reminded me, with a smile in her voice.
I let out a grunt in response.
"Now then," she said as she let go of my cock and stood up, "I want you to clean the whole bathroom, from top to bottom. The walls, the floor, the tub, the sink, everything should be shining by the time you're done. Use this soap for the toilet, and this spray for everything else. Here is a Swiffer for the floors and where did I put that... oh, here it is! The dry wipes and the wet wipes. Before you do that, though," she continued as she walked over to the closet and retrieved a vacuum, "use this. Okay? And I want you to stay hard the whole time. Any questions?"
This was new. Not just the staying hard part, all of it. Before she had just had me clean the floor or the tub and then switched me to another task. This was a new level of independence. I wondered if the increased level of trust would lead to increased rewards.
"No, ma'am," I said as I stood up and took a step towards the bathroom.
"Wait, what is that?" she asked, pointing at my half-hard dick. Did she actually expect me to stay at full-mast while she gathered the cleaning supplies? I realized then that staying hard while cleaning an entire bathroom was going to be impossible. She was giving me an impossible task.
"Get it hard again! Or is that as hard as it gets for you?"
I began to masturbate and quickly regained my erection. She smiled and gave it a stroke.
"Keep it at that level, I don't want to see it soft."
"Yes, ma'am."
I began to clean the bathroom and almost immediately became flaccid. It wasn't my fault, I tried thinking about how sexual this situation was and even had pornographic images of my Mistress from her online profile floating through my mind. But as I cleaned the toilet bowl followed by the seat and cover, I found myself completely flaccid. There was no helping it.
"Step out here," she ordered from the hallway.
I put the toilet brush down and stepped out of the bathroom.
"Why are you soft? Ugh, nevermind, just get it hard again!"
I began to masturbate but my dick was no longer cooperating. We stood there in silence watching as I played with it in vain.
"Useless!" she exclaimed, and reached for my dick. She furiously masturbated it, but little changed. With her other hand she grabbed me by the hair and pulled my head back. "You like it when I take control, don't you?"
Almost immediately my cock sprang back to life. She gave it a couple more strokes and then stepped back.
"Do NOT let me see it soft again!" She ordered as she walked away.
I went back to cleaning. Well, to be more accurate I was cleaning with one hand and steadily masturbating with the other. But it wasn't long before I had to use both hands to scrub something or stabilize myself and my erection disappeared. It was impossible. I gave up on it and went back to cleaning.
A few minutes later she called me out of the bathroom to inspect me. Once again she chastised me and used her hand to get me hard again. This time it took even longer than before. I stood there feeling the shame of disappointing my Mistress, of not being able to do this for her. I think that if I was a normal person, not a submissive, I would have simply enjoyed the handjobs. After all, that had to be her plan, right? It was an excuse to make me take a break and get jacked off every 5-10 minutes. But I was a submissive, and she was my Mistress. And getting a handjob from her was not nearly as satisfying as getting her approval. My cock finally responded.
"I guess that's as hard as it gets, huh? Like a ripe banana. Oh well, good enough. Back to work. And actually try to stay hard this time, hmm?"
I turned around and went back to the bathroom. I did not attempt to stay hard. I was done. As I scrubbed the tub, I began to ruminate on the impossibility of the situation. It wasn't fair. I needed a fair chance at impressing Mistress. But how could I stay hard this whole time? Maybe it wasn't an impossible task, maybe there was a solution. I could... watch porn? No, she wouldn't like that. Maybe... a cock ring? Or lacking that, a rubber band? But I didn't have either of those. My mind wandered back to the nudes of my Mistress. The one of her hanging nude from ropes with a gag in her mouth. The one of her spread pussy and asshole, with her ass covered in fresh whip marks. My dick twitched.
After scrubbing the tub and shower walls I dissasembled her shower enema (at the time I thought it was some weird hair-washing attachment) and used it to rinse the walls. She leaned in to the bathroom and observed me. I thought she might compliment my ingenuity.
"You're soft again? Step out here."
I silently turned off the water and turned to dry my hands. I had trouble hanging the towel back on the tiny hook. My frustration grew.
"Hurry up, bitch."
I turned and stepped out of the bathroom.
"Why the fuck are you soft again? Why can't you follow simple directions?"
I looked down in shame and frustration as I attempted an explanation.
"It's hard to stay hard while I'm cleaning a whole bathroom, ma'am."
"You think I give a fuck?" she asked incredulously. "That's not my problem. Figure it out."
I figured that I had nothing to lose. Might as well give it a shot. If she really wanted me erect maybe she would do this for me.
