Erotica Sex Story: Chapter 7 - I'm Zihan, the model student: top of my class, class monitor, and a "good boy" in every sense of the word. My life is a straight-A report card, my only failing grade being my crippling timidity around girls. That was until Sam transferred into my school and, by some twist of fate, became my desk mate and a guest in my home. Sam is my complete opposite—confident, and effortlessly at ease with everyone, especially women. Under his wing, I start to shed my awkwardness

Sam’s suggestive wink instantly piqued my curiosity. “Zihan, in South Africa, boys our age have all played ‘the grown-up game’,” Sam said with a lecherous grin, making me even more intrigued.
“What exactly is the ‘adult game’? Is it like real-life CS shooting?” I really had no idea what Sam was talking about, even though I enjoyed watching girls on TikTok striking poses.
“You really don’t know? Zihan, is education in China that backward?” Sam widened his round eyes, looking as if he was shocked that I didn’t understand what he meant by the “adult game.”
“I really don’t know...” I rolled my eyes at him. I’ve received a proper, traditional education since I was young, so how could I possibly know what Sam meant by this game, especially one played by adults? “Hehe, Zihan, I’m worried I might corrupt you. Don’t tell Mom,” Sam squinted his big eyes and whispered mysteriously. “Of course I won’t tell Mom. I’m not that bored,” I rolled my eyes at him again. If he had something to say, he should just say it instead of dragging it out.
“Alright, it’s a deal,” Sam started grinning mischievously again. “The ‘adult game’ is a game played between men and women. In short, it’s sex.” Sam said this with a straight face, even gesturing with his hands. “Sex? You mean when a man and a woman use their ... reproductive organs to mate?” I understood that much—my middle school biology classes weren’t for nothing.
From middle school biology, I knew that the male reproductive organ is called the penis, and the female reproductive organ is called the vagina. When a man’s penis enters a woman’s vagina, after a certain process, the penis releases sperm, which combines with the egg released by the woman in her vagina. After further reproductive development, a fertilized egg forms. Everyone goes through this biological process, eventually becoming the fully formed individuals we are, with heads, faces, hands, and feet.
“Right, so you do know, Zihan,” Sam looked at me. “If the adult game is sex, then isn’t sex something you only do when you want to have a child?”
I was still a bit confused. Even after going through compulsory education, I still didn’t fully grasp Sam’s meaning.
Sam said he often played the “adult game” with his girlfriend in South Africa. Didn’t that mean he had a lot of children?
“No, Zihan. Sex is indeed the process of having children, but you can have sex without having children,” Sam opened his big eyes wide. The whites of his eyes looked much whiter than those of us Asians, probably because he’s Black. Apart from his eyes, mouth, and the palms and backs of his hands, the rest of his skin was dark.
“Then you just have to make sure the sperm doesn’t enter the woman’s vagina, otherwise she’ll definitely get pregnant,” I said. Although middle school biology taught that sperm doesn’t always combine with a woman’s egg 100% of the time, there’s still a chance, especially during a woman’s ovulation days, when it’s very easy for her to get pregnant.
“Exactly, so you have to take protective measures during sex. You know about condoms, right? They’re worn on a man’s penis so that when he ejaculates, the sperm doesn’t enter the woman’s vagina.”
Sam explained this to me very seriously.
“Oh right, how could I forget about condoms?” I suddenly realized. Condoms are exactly for preventing pregnancy.
“Since you already know, how about I show you some videos of the games adults play, huh?” Sam came over to me, winking and grinning with his thick, sausage-like lips curling upward. Honestly, I don’t know if it’s because I’ve entered what they call puberty, but I really want to learn about these things and feel a sense of longing. Naturally, my thoughts drifted to our class monitor, Li Xiaojun.
“Uh, it’s pretty late now, I’m not really in the mood to watch,” I said, even though I actually did want to see. I just didn’t want Sam to think I was some kind of troublemaker. After all, when he said “games adults play,” he meant sex—putting a guy’s penis into a girl’s vagina. Isn’t that just porn?
But a little fun never hurt anyone, right? I thought I’d watch secretly when I was alone, just like how I secretly watched those TikTok girls shaking their butts and showing off their cleavage.
“Alright, Zihan. Let me know when you want to watch. I’ve got plenty of fun stuff here,” Sam said, returning to his bed and giving me a sidelong glance. “Okay, Sam, let’s go to sleep. Goodnight,” I replied, looking at him before pulling up the covers, closing my eyes, and trying to drift off.
“Goodnight, Zihan,” Sam said, lying down on his bedroll. Since my bed was about fifty centimeters higher than his mattress on the floor, he disappeared from my view once he lay down. All I could hear was the sound of him tossing and turning beneath me.
Even though I had turned down Sam’s “kind offer,” my mind kept wandering back to thoughts about “sex.” It was just too tempting. I remembered the abstract diagram of a girl’s vagina from our middle school biology textbook. To me, it looked like a little pot, giving me a strange sense of familiarity.
As these thoughts swirled in my head, images of Li Xiaojun’s innocent face kept popping up, making my “little brother” start to stir. “Mmm...” A strange sound came from under the bed, startling me. It sounded uncomfortable, but to my ears, it was oddly pleasant, like a beautiful melody that excited me.
Was Sam still awake? Could he be making that weird noise in his sleep? The thought gave me goosebumps.
Luckily, the strange sound only happened once.
After a while, I heard rustling noises from under the bed again. I don’t know how much time passed, but just as I was drifting off to sleep, a heavy, rough breath—”Huff...”—woke me up again. I knew it was Sam. Curious, I sat up and looked down. He was buried under his blanket, and nothing seemed out of the ordinary. Maybe he was just dreaming again. I was so tired that I lay back down and, in my drowsiness, finally fell asleep.
“Zihan, it’s so hot. Why don’t you take off your clothes?” Li Xiaojun’s clear voice suddenly rang in my ear. I turned to look and saw her walking toward me, wearing a green bikini like the ones those TikTok girls wear. Wasn’t I sleeping in my bed at home? When did Li Xiaojun get here? And why was she in a bikini?
“Okay,” I found myself agreeing, and I took off my shirt, feeling my upper body exposed.
“Why not take off your pants too? Let me help you,” Li Xiaojun said, walking right up to me. Her long, delicate, pale hands reached down toward my lower body. Was Li Xiaojun really helping me take off my pants?
As I watched her slender hands move downward, why did it feel so incredibly good?
“Zihan,” I was still basking in the pleasure Li Xiaojun had brought me when a dark face appeared from behind her. As Sam emerged, I noticed Li Xiaojun’s eyes narrowing into crescent moons, her sensual lips parting slightly. “Mmm...” A strange sound escaped her mouth, revealing her pearly white front teeth. Her saliva-coated tongue peeked out from between her parted lips. In that instant, I saw through her black-framed glasses perched on her high nose bridge—her eyes rolling slightly upward toward me, the corners of her mouth curling into an eerie smile. “Zihan,” Sam’s dark face turned to me with a grin. “Mmm...” Another strange sound came from Li Xiaojun’s mouth. I even saw her breasts, each small enough to cup in one hand, swaying back and forth beneath her bikini top. “Sam? Don’t...” For some reason, as Sam’s dark face drew closer and closer, I felt as if we were about to press together. Startled, I pushed his dark face away with all my strength.
“Zihan, Zihan, what’s wrong?” I opened my eyes in terror to find a dark face hovering close to mine, its large, round eyes filled with concern.
“Damn it! Sam!” I jumped in fright again, immediately scrambling to the side and sitting up. “Zihan, what happened? Are you okay? I heard you moaning and groaning in your sleep. I kept calling you, but you wouldn’t wake up. You scared me,” Sam said anxiously, patting his chest. What happened to me? I was dreaming about your damn dark face.
But that dream ... why did it feel so real? Especially when Li Xiaojun reached down between my legs—I even felt a tingling pleasure.
“Ah, Sam, I’m fine,” I said, glancing out the window where the sky was bright and clear, with not a cloud in sight.
“Good, I’m glad you’re okay. Zihan, hurry up and get out of bed. Mom just knocked on our door,” Sam said, relieved to see I was alright.
“Alright, let’s get up,” I replied. Damn it, it seems Sam’s dark face is so deeply ingrained in my mind that he even invades my dreams. What a shame—such a beautiful dream ruined.
Noon, in the kitchen.
