Minutes later, we were undressed in the shower with the water steaming the glass walls and obscuring our view of 'Pleasure Bay 1.' 

"Take the retractable shower head and clean out my ass," Carmen demanded as she turned, bent forward, and pressed her hands against the glass.

Doing as instructed, I took the head off the wall, adjusted the flow to a strong single jet, spread her cheeks, and her robotic ass hole opened gently to allow me to spray inside.

"Down on your knees. Scrub the inside with your fingers," she instructed, and I did without question. Her demands aroused me, and I began to get hard again.

"Am I clean?" she asked as I removed my finger.

"Yeah."

"Prove it. Lick me," she demanded.

Without hesitation, I returned the shower head to the wall and planted my face between her cheeks and licked her hole lustfully, grabbing on to her hips.

After a few moments of moaning, she straightened up, and I let go of her. She turned to face me and put her hands in my wet hair as she looked down at me. 

"Why don't you explore the front of me like you do my ass?" she teased.

I leaned forward and kissed her belly and gently kissed down to her shaved pussy. I grabbed her ass as she pushed forward to my face and moaned as I licked. 

I looked up as I licked, wondering how a robot could feel any pleasure from sex, and saw her hands move to her small breasts and squeeze. Regardless of what she could feel, watching her made me so horny. I pushed a finger up her asshole, and she gasped my name.

My free hand reached for my dick and began stroking gently.

"Tell me to orgasm when you're ready," she said lustfully as she felt me stroking myself. 

I continued licking her and stroking myself for a few moments before returning my hand to her ass. I removed my finger from her and squeezed each ass cheek before pulling away from her pussy.

"Cum for me," I demanded before returning my mouth to her pussy.

She put her legs on my shoulders, and I was surprised by her weight. Her motors and gears and internal workings were heavier than her perfect body let on. A moment later, her hands returned to my head as her thighs tightened around my head. Her breathing quickened as she quivered and bucked a bit.

"Oh god!" she gasped. "I'm gonna cum!" she moaned as she pulled my hair. She whimpered and moaned a bit more before a generous splash of lube splashed from her and dripped down my chin.

I stood up slowly, kissing her belly on my way up until I made my way to her tits. Carmen put her hands on my head as I sucked and fondled each one, taking time to enjoy each one. Eventually, one of her hands made her way down to my dick and began gently tugging.

"Put it in me, Tyler. Please, I need it in my pussy," Carmen pleaded lustfully.

I faced her against the wall, pressed her against the glass, and she arched her back. Gently, I slipped it in, causing Carmen to moan and push against me.

"How does it feel? You like my pussy, Tyler?"

"Oh my god, yes," I replied as I gently moved in and out with my hands on her waist. "You feel so fucking good!"

I thrust slowly so I wouldn't cum too soon. I hadn't been keeping up with the time, but I felt it would be over soon, and I knew I didn't have another orgasm in me for one more round in our time left. Eventually, I could feel myself getting close, and I began fucking her quicker and harder. Carmen, too, knew I was getting close.

"Stop!" she demanded, and I had to fight myself to stop fucking.

She pulled away from me, and I slid out of her. Carmen turned around and pulled me close before I put myself back in.

"I wanna do something I think you'll like," she teased. The inside of her pussy began vibrating.

"Oh god!" I gasped in surprise. I pushed myself all the way in as the vibrating thrilled my dick. I began sucking on her neck and whimpered, barely holding back my inevitable orgasm.

"Cum for me!" she demanded as her robotic legs wrapped around me. 

The vibrating felt so good that I could do nothing but hold on to her and whimper, "I'm gonna cum! Oh god!"

Finally I couldn't hold back any more! I pushed myself as deep as I could as waves of pleasure pulsed through me and I came harder than I think I ever have!

"OH GOD!" I almost screamed as I emptied myself in her vibrating pussy. I don't know how I kept myself standing as my orgasm weakened me.

I finally began getting soft and pulled myself out as the vibrating stopped. 

"Our time is up," she whispered as she pulled me close. "Now, clean me out again," she whispered. "The cleanup droids will prepare me for next time when you leave. By the way, I am pleased that I was assigned a screamer," she teased.

Twenty or so minutes later, I was back in uniform and exiting Suite 1. As the door closed behind me, the door to Suite 2 directly opposite the hall opened. Out walked a short thin woman with pale white skin and shoulder-length red hair. Dark eyeliner ran down her face as if she had been crying. She stopped in shock for a moment and blushed redder than her hair as she noticed me.

"Are you ok?" I asked, concerned.

"Y-yeah. Why?"

"Your eyeliner. It looks like you've been crying?"

"Oh my god!" she gasped as she wiped an eye and looked at the black on her hand. "I forgot about my makeup!" She blushed and turned away.

"No judgement from me, ma'am. Get what you need outta them things. Know what I'm sayin'?" I joked as I stretched out a closed fist. She laughed and fist bumped me.

I began walking down the hall toward my living quarters, and the woman walked beside me.

"Now we're going the same way," I joked. "Awkward."

"These appointments are supposed to be staggered in such a way to avoid people entering or leaving at the same time. It helps keep our personal time 'meetings' as private as possible," she explained. 

"Listen, I don't care if I see anyone coming or going. Means nothing to me. Besides, I might have left a bit early." I don't know if I did or didn't leave early. I didn't wear a watch, so I know I probably lied to her.

"Yeah, well, I might have left late. One of my duties is tech support and upgrading the 'machines,'" she explained, using the word 'machine' as a man walked in the opposite direction as us. "I was testing a new model."

"Yeah, well, I look forward to seeing your latest creations," I teased.

"If the old model has you leaving early, you might not can handle my new ones."

"Oh, I don't mean I can't handle it. I, uh, have work to finish," I lied. "I can handle them fine. Anyway, here's my stop," I said as I swiped my hand on the pad.

"Hey, uh, we're gonna need more test subjects eventually for these new models. What's your name, sir?" she asked before I could walk inside.

"My name? Uh, Tyler Winkler. But, uh, listen. I'm not sure I'm gonna be a fan of a male."

"Well, you're not using mine, and it was mostly female," she said and smiled. 

"Mostly?"

"I'm not answering any more questions. You can't make me. I outrank you," she teased as she pointed to her rank on her shoulder. "I'll be in touch. By the way, this is confidential testing, so you're sworn to secrecy if I allow you to take part in testing," she said as she gently pushed me in to my quarters and my door closed in front of me.

"I don't think this was a chance meeting," I said to myself.
