Passionate Clean Room (Experience Story Adult Novel)

I am an engineer in a telecommunications company. I was called in for repair because the phone in the manufacturing department of a biotech company that produces human vaccines was out of service. Since non-staff members are not allowed to enter the production line on weekdays, I could only arrange for it on Saturday, the weekend. Coincidentally, the General Affairs Section Chief was on a business trip, so he arranged for Zhang Xintian from the General Affairs Department to lead me in the maintenance project. Since I had often come into contact with her during previous maintenance work, I was quite familiar with her and knew that she was married and had a child. But her figure and appearance don't look like a married woman, but more like a young girl pursuing fashion.

The maintenance site needs to enter the clean room. The original separate changing passages for men and women are very troublesome and I don’t know how to wear a full set of cleanroom clothes, so she had to teach me how to put on a full set of cleanroom clothes in the boys’ locker room. I saw her wearing a denim skirt and a one-piece cleanroom clothes. She could only lift the skirt up to put on the trouser legs, and then I could see her black underwear.

My zipper was stuck at the bottom and couldn't be closed. She said it often happens because of poor zipper design. Seeing that I was clumsy and unable to exert my strength, she reached under my crotch to help me undo the stuck part of the zipper. Because it took a little effort to pull it, her hand inadvertently touched my penis through my underwear. But she acted as if nothing had happened. Instead, my cock became hard after her stimulation, and it made the lower part of my loose dust-free clothes bulge out obviously.

Later, she went to another location to add a new telephone extension, which required her to enter another sterile room to investigate the path construction method for laying the line. That sterile room was of a higher level and required one to shower, change clothes, and then change clothes twice before entering. Because her personal antiseptic shower gel and sterile supplies were all in the women's room, and she thought there was no one there on weekends, she simply asked me to go with her to the women's locker room through the female employee entrance and the changing passage. She only gave me a pair of transparent sterile panties that were like disposable pants and asked me to go to the bathroom to shower first. Later, I heard her come in and take a shower in the room next to mine, and she handed me bath products through the ten-centimeter-wide gap below. Just as I bent over to get her bath products, I looked up slightly and could see her thighs. She also told me to wash my private parts and hairy areas very carefully. In fact, the shower room was covered with a curtain, so there was a small gap through which I could see what was inside. I finished washing before her and came out, and I could clearly see her naked body out of the corner of my eye.

I stood there waiting for her to come out after washing. When she came out, she was wearing sterile underwear on her lower body and a large towel around her upper body. But she didn't feel embarrassed. She just stared at my lower part in a daze, because my penis had been hard and swollen since I peeked at her naked body, and now the glans had already popped out of her pants and was exposed outside. In addition, the size she gave me was the largest one for women, which was still a little too small.

Seeing that she was too embarrassed to speak, I spoke first: "Is it okay to enter the sterile room like this?" I asked her.

She said: No way! How can we leave it exposed to the air like this?

Me: But it seems like I can’t fit it into my pants?

She: You figure out a way to stuff it in!

I tried for a while but couldn't put it in, and I accidentally tore the non-woven sterile pants!

This time what she saw was not just the glans, but my entire enlarged and hard penis.

She: That’s too exaggerated! This way you can also pierce through it!

Me: I’m sorry! I need to change it to another one!

She: Of course I can’t do anything if you keep it hard. Did you make it soft?

Me: How do you want me to do it myself?

She: Don’t you men know how to do this?

Me: I don’t know about others, I can’t get out by myself.

She: How is it possible?

Me: If you don’t believe me, let’s make a bet. If I can’t cum for five minutes, you can do whatever you want!

She: Okay! I don't believe it. Do you think I'm a little girl who is easy to fool? I'm married and have children.

I started masturbating in front of her, swinging it very hard and fast!

After three minutes, I still had no urge to ejaculate, so she just watched me masturbate in front of her.

I felt her hands, which were originally wrapped around her chest, getting tighter and tighter, curling and pushing her breasts.

She said: You are really awesome! If my husband had been so fast, he would have ejaculated long ago.

Me: I told you, I can’t get out by myself!

She: It’s not time yet! I wonder if you can really hold on?

Me: Compared with the ones you have seen, is mine bigger or smaller?

She: How should I know? My husband is the only man I have!

Me: Then who is older?

She: It’s not accurate to look at it! I’m not sure either!

I grabbed her hand and put it on my penis: Then feel it with your hand, and then think about your husband's?

She did not resist and really held my penis seriously, moving it up and down slightly from time to time as if measuring the length.

She: Yours seems to be longer and harder. My husband's is thicker than yours but not as long and not as hard.

I said: Five minutes are up, do you want to try and see what different feelings different cocks will bring you?

Xintian kept stroking my penis with her hands, her little mouth slightly opened, and she looked at me from time to time with her big eyes, with a lewd expression on her face.

"Turn around a little!" I said, moving my penis closer to her. Xintian looked up, then knelt between my legs, smelled my penis, and gently licked the glans with her tongue. She felt no odor, so she put the entire penis into her mouth. I immediately felt like I was being electrocuted all over.

Xintian held my penis in her mouth, her tongue rolling inside it, her saliva flowing down the penis, and her hands wet with saliva were stroking it for me, making sounds of "hmm... umm... umm... ah..."

Xintian became more and more interested in eating. She first stretched out her long tongue and licked from my balls to my glans. Then she put the entire penis in her mouth, and her tongue flexibly rotated around the glans. She stopped from time to time to breathe, rubbed my penis with her hands dipped in saliva, and then sucked hard, licking my urethra with the tip of her tongue.

"Fuck! This slut is really good at it!" I touched her long hair with one hand and reached down to rub her breasts hard with the other hand. Enjoying a blowjob from a beautiful girl, this is a scene that I could only dream about before!

Every time her skillful tongue tip brushed across the glans, I felt an electric current passing through my whole body, and the extreme pleasure made me gasp for air. I haven't done it for a long time, and this time it's so exciting. I feel my penis is swelling as if it's going to explode, and waves of soreness and numbness are coming from below.

"I can't stand it so soon! "I thought to myself, holding her head with both hands to help her speed up her oral sex. Xintian seemed to sense something and struggled to spit out the penis. The more she struggled, the tighter I held me. Seeing that she couldn't get free, she simply speeded up the movements of her hands and mouth.

"Ah~~" With a dull cry from me, a hot stream that had been suppressed for a long time finally shot into her mouth. Because of excitement, I still held Xintian's head tightly and leaned my body back hard, and my penis almost hit her throat. After shaking for a few times, a lot of semen came out. I kept my penis in her mouth, so I couldn't spit out the semen, so Xintian had to swallow it all...

She spit out the penis, white semen overflowed from the corner of her mouth, and said angrily: "What are you doing? It's so disgusting! You ejaculated into my mouth! I ate a lot. I will never help you again!"

"It feels so good. I didn't realize before, but you are so good at oral sex!" I teased.

"How can you normally see this?" When Xintian spoke, there was still a stretch of mucus between her lips and the glans.

My penis didn't get smaller due to ejaculation, it just became a little softer. Xintian also licked my glans again. Maybe it was because we hadn't done it for a long time, and under the stimulation of her tongue tip, my penis became hard again.

"I didn't realize your penis was so strong! It's still so powerful right after you ejaculated!" Xintian gently flicked my penis a few times with her hand and looked at me eagerly.

When I heard that, I became even more excited. I picked up Xintian and put her on the table. I kissed her neck and face, and started attacking her breasts with my hands.

"Slow down! You're still so impatient after just ejaculating. Be gentler when you grab my breasts!" Xintian said while panting.

The soft sound stimulated me even more. Even as a married woman, her breasts still feel so great. Even when she is lying down, they are still firm. There is a light areola, and the small nipples on it are also hard. She held my head with both hands and pushed it down, moaning softly: "Oh... um..."

My hand slowly moved down, into her panties, and touched her pubic hair. Wow! It's already overflowing. I stretched out my middle finger and placed it in the middle of her slit, gently touching it, slowly separating her labia, and inserting my finger into the slit. Her two labia were also separated to the sides, and my fingers gently twisted her labia minora. Xintian moaned, slowly separated her thighs, and the love juice flowed out of her vagina.

As my middle finger went deeper, Xintian's buttocks lifted up, and her legs were bent and spread apart on the table. "Ah... stop teasing me, hurry up! I can't stand it anymore, come in!" Xintian moaned.

"Why can't you stand it? You asked me to slow down just now, and now you ask me to speed up!" This time I take the initiative and I want to take this opportunity to recover my strength.

Xintian has a first-class figure, without any extra fat, and her breasts and buttocks are still very perky. I have noticed this in my usual observations.

I easily pulled off Xintian's panties and kissed her pussy directly. Maybe because she had just washed, her vagina didn't have any fishy smell, and it even felt slightly sour when I licked it with my tongue.

"Ah... No! Don't kiss there! Oh~~"

Of course I couldn't listen to her at this time: "You served me just now, now it's my turn!" As she spoke, her hot air sprayed on Xintian's pussy, making her moan again.

I continued to lick her vagina, occasionally thrusting my hard tongue inside, imitating the thrusting of a penis, moving in and out. Xintian pressed the table with both hands, and lifted her entire body upward with her hips, leaving the table except for her feet and shoulders. I just reached my hands under her plump buttocks and lifted them up, which made licking more convenient and my tongue could go deeper. The raised butt gives a woman a kind of lustful pleasure of being naked, and Xintian's previous reserve in front of me was swept away.

"No! Ah... No... Don't lick me anymore! Ah... Fuck me! Put it in... Ah... I'm so itchy... I can't stand it!"

Xintian spread her legs wider, swayed her body from side to side, and her snow-white breasts kept shaking. Her anus gradually opened, revealing the pink tender flesh inside. I gently touched her anus with my finger, and suddenly a stream of hot water shot out from her pussy and splashed all over my face. It turns out that this slut's sensitive spot is her asshole. Next time I have the chance, I must enter her from the back door and satisfy her anus.

I thought the time had come, so I lifted her legs and put them on my shoulders, and inserted my penis into her pussy. The penis was inserted into her flesh hole little by little, and finally it was all in. Xintian let out a long scream: "Ah~~~~~~" which echoed throughout the bathroom.

So tight! The penis was tightly surrounded by Xintian's vagina, giving a warm feeling. As I slowly pulled out, bringing out the layers of tender flesh inside, I grabbed her breasts with my hands and increased the speed of my thrusts.

"You're so bad! Ah... I don't let you touch it, oh~ there... but you keep licking it!"

"How can you reach a climax so quickly without licking my asshole? Didn't you just lick my sensitive parts back and forth?" I teased Xintian while thrusting.

My thick cock penetrated the deepest part of Xintian's vagina with each thrust. Xintian moaned loudly with each insertion. Her obscene cries of "Oh Yeah! Oh Yeah!" echoed in every corner of the bathroom.

Seeing her so excited, I jokingly said, "Be quiet, don't let others hear!"

"Ah...ah...tell me to keep my voice down, ah...ah...you're still working so hard? Ah~ it feels so good! Ah...how can I not scream out? Ah~" Xintian said while moaning.

This little girl was so wanton. I quietly pulled out my penis, leaving only the glans to rub against her hole. Xintian responded quickly: "Stop playing with me, fuck me! Ah... fuck me!"

I increased the rhythm, and her expression looked painful, but she was so happy that she cried out:

“Ah…ah…oh…God! You’re making me fly…mmm…mmm…ah…ahhh! I can’t take it anymore…”

Although autumn is not very hot, I was still sweating profusely due to the intense activity. It might be because I just ejaculated and I haven’t felt like coming again yet. I pulled out my penis, bringing out some of the liquid, pulled Xintian up, and sat next to her. Due to excessive stimulation, my two scrotums have shrunk to a very small size, tightly attached to the penis, almost becoming a whole, appearing thicker and with blue veins.

"Please sit on it! Let me rest for a while."

She came closer and looked at my penis and said, "It's much bigger than when I gave you a blowjob just now. How is this going to fit in?"

"Why are you pretending? I just pulled it out of your cunt!"

Xintian turned her back to me, holding my penis with her hand (in fact, it was so hard that there was no need to hold it at all. Maybe she wanted to find the right position to avoid inserting it into the wrong hole), and then she sat on it carefully. The penis slowly disappeared into the pink crack. I put my hands under her arms and rubbed her breasts. She panted slightly, closed her eyes, turned her head to kiss me, and stuck out her little tongue to entwine with mine.

Xintian half squatted and half sat on me, supporting herself with her hands, gently lifted her body, and then sat back down. I also held her slender waist and moved her up and down. Her soft breasts finally broke free from the restraint of my hands and began to sway up and down.

In order to pursue more intense stimulation, Xintian actively swayed her waist and moved it up and down (this is called grinding tofu). In this position, the penis can be inserted very deeply. Because my penis is too big, Xintian dare not insert it completely, and about an inch of it remains outside the vagina each time.

Xintian moved faster and faster, making unclear moans. I whispered in her ear, "You're so tight down there! It feels so good. Haven't you been fucked in a long time?"

Xintian frowned and panted, "You're taking advantage of me! Ah... since I gave birth to the child, ah... I haven't been fucked. Oh... ah... it feels so good! Go slower... otherwise I wouldn't have let you take advantage so easily! Ah~~"

I held her slender waist and pressed down hard, inserting the entire penis into her, with the glans directly hitting the center of her flower. With a long scream, Xintian orgasmed again! I felt a heat wave rushing to my glans, and my entire penis was scalded. I almost lost control of my semen, and the vaginal fluid flowed down my penis, over my thighs, and dripped onto the sofa and the floor.

"You are so bad! You suddenly inserted it so deep!" Xintian complained, turning her head back.

"You're so good!" I said while kissing her, "Let me fuck you from behind this time!"

"You have so many tricks!"

"How can we deal with a slut like you without a few more tricks?" I helped Xintian stand up. She cooperated and lay on the wall with her face almost touching the wall. Then she raised her ass and faced her pussy towards me.

I grabbed Xintian's hips with both hands, looked at her tender pussy and asshole, and had evil thoughts. I rubbed the tip of my glans in her labia, then aimed at her asshole and prepared to insert it. Xintian noticed it as soon as I hit her, and she tried desperately to avoid it by shaking left and right, but I held her hips tightly and her anus rubbed against my glans, and waves of numbness spread all the way to the top of my head.

"No! You can't insert it there... Ouch! Don't... Please... Really can't! You'll make me angry again!" Xintian begged.

When I heard that, of course I didn't dare to insert it forcefully, and my penis slipped into her tender vagina again. My favorite position is the "doggy style" from behind. The rhythm is completely controlled by me, and in this position the woman's pussy is the tightest. I was so excited that I was about to come. I didn't want to play any tricks this time. I just increased my speed from the beginning, going straight to the center of the flower with each stroke. With each pullout of the penis, some of the vaginal fluid dripped onto the ground, and my two breasts shook violently.

"Ah... you are such a bad guy. The first time I fuck you... you want to fuck me from behind... ouch!"

Xintian’s lewd cries became louder and louder, and I also fought forward desperately as if I heard the charge.

"Let's find another time later...just do it like we did today!" I said breathlessly.

"Ah~~ Do you really want to fuck me again? Um...ah..."

I didn't expect that Xintian, who is usually dignified and elegant, could be so unrestrained. I couldn't bear it anymore. The feeling of the arrow on the string became stronger and stronger, and my penis began to tremble.

"You really fucked me... fucked me... ah... it feels so good... ah... don't stop..."

The big cock was getting so excited that he couldn't stop even without her saying anything. The glans was swollen and was about to ejaculate. Xintian felt that the cock in her vagina was getting stronger and bigger, so she simply squeezed her vaginal flesh and cooperated with me to get the full pleasure.

"Mm...fuck me...ah...harder...ah...ah...I feel so good...ah...cum inside me~~I want you to cum inside me...mm...ah..."

With a low roar, I shot my semen into the deep of Xintian's vagina. She responded by moaning loudly. The hot semen hit her vagina, bringing her another orgasm. Xintian's vagina tightened and relaxed, tightened and relaxed again, like a mouth sucking out all the semen, and waves of pleasure spread from my penis throughout my body.

I felt sore all over. After resting for a while, my penis slowly softened in Xintian's vagina. I then reluctantly pulled it out.

"You're so great, I've never felt so good before!" Xintian whispered in my ear.

"You're not bad! Your flute skills are so good. We'll have a lot of fun in the future."

"You are so bad! I won't let you fuck me anymore!"
