[Experimental Class]

page views:1 Publication date:2023-03-23

During that biology lab, the teacher said she wanted to look at male sperm cells!
(I don't know what she was thinking.)
She wouldn't let us bring them from home, saying the sperm would be dead by then, and we had to come to school to get them. She even

brought some pornographic magazines from her husband's place.
Every boy in the class was passing the buck, nobody wanted to go. My group was the worst off because

I was the only guy in my group (three diagonal lines), so I had to go. With four girls watching me like that,

how could I refuse?
One of them was the group leader, Lingxuan. She was the type of girl who got good grades but was very talkative and nosy

, wearing thick-rimmed black glasses.
She told me to hurry up and not cause trouble for the group. I thought to myself, "This isn't something that can be rushed

, sis! Why don't you do it yourself!"
I still grumbled and took my book to the bathroom. When I got there, I was dumbfounded! The restroom was full, so I had to go to one that was farther from

the lab . Once inside, I opened a book, and immediately realized that porn was

far more exciting than any book. Books held no sexual interest for me.
The restroom was eerily quiet, almost deserted. Then a couple entered.
The man said, "There shouldn't be anyone here, right?"
The woman replied, "Bringing someone here, you're such a bad person!"
I immediately recognized them as Ahua and Mengxuan from my class. They chose the stall next to mine, and I

didn't dare . They were incredibly bold, making love right there next door. Mengxuan kept moaning. Since they were

a couple, they could use this method to collect sperm (menstrual blood), while I was risking my life to travel to the West!
But this is great! I can use this opportunity to collect semen. I wish I could see it, but

no matter how I crouch down, I can only see the four-cornered beast's feet. I can only rely on my imagination. What excites me is that they

are right next door. The wooden wall is constantly pounding and vibrating, showing how intense it is.
I'm already erect. I really envy them. The wall is vibrating more and more intensely. It seems that Ahua is almost there.

Mengxuan panted, "Ah... Hua... no... ah... don't do that to me anymore... today... is my

... dangerous period... I can't do this... I'll... get pregnant... ah... I'll use my mouth... to help you...

please stop inserting it... it's so bad..."
Mengxuan's moans are so sexy! She's beautiful and has a curvaceous figure. Later, the wall vibrated a couple more times

before stopping. I heard the sound of saliva slurping. I think Mengxuan was giving him oral sex! I

didn't dare . After a while, suddenly there was a noise
that startled the three people in the bathroom. It was the group leader, Lingxuan. She shouted, "Jincheng! Are you done yet?

We've been waiting for so long!"
Her shout startled Ahua and Mengxuan even more. I pretended not to know anything

and replied , "Not yet! Your shout made me shrink back!" (I really did go limp.)
They realized the voice was coming from next door. So they had just... They both fell silent.

Lingxuan said, "What should we do? The teacher is urging us!"
I said, "There's no other way! Come in and help me."
Lingxuan paused and replied, "How can I help?"
The three of them were a little surprised, wondering why I would say something like that.
I said, "Come in first and we'll talk!
" I opened the door and tried to pull Lingxuan in, but she was shy. I deliberately spoke loudly, "There's no one

here , what are you afraid of!" "
The bathroom wasn't too crowded, there was still room to maneuver. Lingxuan said, 'Let's make a deal first, you absolutely

can't touch my body, or I'll sue you for sexual harassment!'
I listened carefully to Ahua and Mengxuan next to me. They clearly wanted to stay and hear what we were going to do,

otherwise they would have taken this opportunity to go back to the lab long ago. I didn't hide it, and Lingxuan said, 'Okay! So

how can I help you now?'
I joked, 'Can I see your naked body?'
Lingxuan slapped me: 'Vulgar!'
The slap wasn't hard. " "Just kidding!" I said with a laugh.
Lingxuan said a little seriously, "Hurry up!"
I thought for a moment and said, "Then you can strike some sexy poses!"
Lingxuan asked, "How? I don't know how!"
I took out a pornographic magazine for her to compare.
When Lingxuan saw the naked men and women in the book, she blushed with embarrassment. I said, "Hey! What's wrong? Hurry up!"
It was the first time Lingxuan had been forced to strike such a seductive pose, and she became shy on the spot, but she had no choice but to do it.

Although her movements were clumsy, she still managed to strike a pose in a decent manner.
Actually, upon closer inspection, Lingxuan is quite pretty, she just doesn't know how to dress. Her beautiful face is hidden by

her glasses . I said, "This isn't sexy enough, unbutton your blouse a little."
Lingxuan blushed and unbuttoned it one notch. I became firm and said, "Not enough! Not enough! Unbutton it another notch." Lingxuan

did as I said, and
you could already see her cleavage. I said, "Just one more notch will do."
Lingxuan obediently unbuttoned it another notch. I don't know why, but Lingxuan, who is usually very fierce, suddenly

became . I like girls like her. It's as if our roles have been reversed at this moment, and I'm

in control now.
I saw Lingxuan's bra. She was wearing a plain white bra. Her breasts were so big that I was surprised. How did she

usually hide them? They looked at least a D cup or larger. I joked, "You've taken good care of them

!"
Lingxuan blushed and lowered her head. Looking at Lingxuan's big breasts, I was already very erect.
I took out my penis and started thrusting! Lingxuan stared at my penis with one eye open and one eye closed, seemingly a little

frightened . I guessed she had never seen a man's genitals before, and I also guessed she was still a virgin. I said, "

Squeeze your cleavage, it'll make it even better!"
She timidly bent down and squeezed out a large cleavage.
I was super excited, but the more excited I got, the harder it was to ejaculate. My penis was too hard, and after a while, I still hadn't

come . My hand was getting sore. I said, "This won't work. My hand is already sore before I even come. Can you help

me?"
She was startled and said, "I don't know how!" I said, "Just like I just did, grip tightly from the front and back."

"Just play with it! Come on!"
She squatted down, touched it with her hand in fear, and then pulled back. I grabbed her hand and touched my penis. I

said, "Don't be afraid! Just take good care of it."
Lingxuan slowly grabbed it and started playing with it. At this time, Lingxuan did not know that her breasts were almost exposed.
From my angle, I could see everything clearly: enormous breasts, barely contained by her bra;

and her small hands were so smooth and tender, like a young girl's vulva. I was almost overwhelmed, but I

held back. I wanted to take advantage of her one last time, knowing
I wouldn't have another chance like this. I deliberately pulled her hand away and said, "Looks like it's still not working

!"
Lingxuan panicked, "What should we do?"
I said, "I have a way that will definitely work."
Lingxuan asked, "What is it?"
I said, "I'm too embarrassed to say!"
Lingxuan said, "Tell me! What time is it?"
I said, "Then promise me you'll help me."
Lingxuan said, "Okay! Okay!"
Afraid of upsetting her, I stammered, "You...you...suck...my...

into "
Lingxuan hesitated for a moment, but then said seriously, "Will that work?"
I thought to myself, this woman is so easy to fool!
I opened a pornographic magazine and showed it to her, saying that it would only work if you sucked and swallowed quickly like this. Lingxuan said, "Mmm!"
as if she understood. So... She was about to give her first time to this stinky man, and she was still a little scared , so she

slightly opened her mouth. I said, "Open it wider, otherwise it won't go in. Remember! Once it's in, you have to hold it in properly

!"
Lingxuan nodded.
She slowly tried to swallow my penis. Although it was already in her mouth, she hadn't closed

it , and I could already feel the heat inside. When she finally took it all in, that moment felt amazing! Although

she couldn't swallow me whole, the warm, sticky fluid, the narrow walls of her vagina, and her constantly moving tongue

were incredibly exciting. People say oral sex is more pleasurable than intercourse, and it seems that's true.
I said, "Move! Otherwise, it's useless!"
Lingxuan's swallowing and spitting, her sticky saliva, filled my entire penis. Because of the lubricant,

my movements became faster and faster. I couldn't hold back any longer. I grabbed her head and started moving my hips, thrusting back and forth

violently. Lingxuan was startled by my actions and tried to escape, but I held her tightly.
In just a few thrusts, I ejaculated into her mouth. She choked a little and quickly spat it out. I got her a container to collect it,

and as soon as she spat it out, she exclaimed, "What are you doing!"
I said, "This is a normal reaction for a guy when he's about to ejaculate!" She stared blankly at the semen she'd vomited,

as if it were the first time she'd ever seen it.
The toilet reeked of a fishy stench, and there was quite a lot of it. After we got dressed, we rushed back to the classroom.

Lingxuan specifically reminded me, "Don't tell anyone about what happened today!"
I promised. Not long after we got back to the classroom, Ahua and the others came in. They got scolded by the teacher, but later, when they examined my

sperm cells, they found they were swimming quite fast. I really have to thank Lingxuan for her help. We smiled at each other.
