The university sports complex was alive with the usual afternoon energy. Students moved between classes, laughing and chatting, but in the girls' changing room near the indoor table tennis hall, the conversation had taken a very different turn.
Lin Xia had just finished changing into her sports uniform — a simple white T-shirt that hugged her slender frame and a short pleated skirt that showed off her insanely long, smooth legs. She was tying her hair into a neat ponytail when she overheard the group of girls whispering excitedly.
"Did you see the new PT teacher?" one of them said, her voice low but full of curiosity. "He's half African. Tall, dark, and built like a beast. I heard he used to play professional basketball overseas before coming here for the exchange program."
Another girl giggled. "I heard the boys in the locker room talking. They said since he's African, he must have a huge dick. Like, really big. Thick and long. The kind that makes you walk funny the next day."
The third girl laughed softly. "Obviously. Everyone knows the stereotype. I bet it's massive. Poor Lin Xia has to take his class today. She's going to be so distracted the whole time."
Lin Xia froze for a second, her cheeks warming slightly. She pretended not to hear and walked out of the changing room, but the words stuck in her head like glue. She felt a strange mix of nervousness and curiosity as she headed to the indoor table tennis hall for the PT class.
The new PT teacher was already on the court when she arrived. His name was Mr. Marcus Kane — tall, broad-shouldered, with dark skin and sharp features. He was in his late 30s, wearing a tight black polo shirt that showed off his muscular arms and chest, and loose black sports shorts. His presence was commanding, and the way he moved made it clear he was used to being looked at.
The class started with warm-ups, then moved to table tennis for the girls.
Lin Xia was paired with a friend. She was focused on the game, her long legs moving gracefully as she returned shots. Her short skirt flared up slightly with every quick movement, drawing eyes from several male students and even some of the girls.
Mr. Kane walked over to her table, his eyes scanning her body openly.
"Lin Xia, right?" he said in a deep, smooth voice with a slight accent. "Let me see your serve technique. You're holding the paddle too tight. Let me show you the correct way."
He stepped behind her without waiting for permission. His tall body pressed close. One hand covered hers on the paddle, the other rested lightly on her slim waist.
"Like this," he murmured, guiding her arm. His hips pushed forward, pressing his crotch firmly against her perky ass as he demonstrated the motion. It felt like a deliberate thrust.
Lin Xia's body stiffened for a moment. She felt the unmistakable hardness of his cock through his shorts — thick, heavy, and already semi-hard. It was much bigger than anything she had felt before. She noticed it immediately, but she didn't pull away or protest. She simply continued the motion as if nothing was happening.
"Good girl," he whispered near her ear, his breath hot. "You learn fast."
He repeated the motion several times, each time pushing his hips forward a little harder, grinding his growing erection against her ass. The double meaning in his words was obvious.
"Make sure you follow through… nice and deep," he said, his voice low and suggestive.
Lin Xia's cheeks flushed, but she kept playing along, her long legs steady. She could feel his cock twitching and thickening against her. It was hot, heavy, and throbbing.
The bell rang, signaling the end of the period.
Lin Xia stepped away politely. "Thank you for the lesson, Sir," she said softly, her voice calm but with a hint of breathlessness.
Mr. Kane smiled, his eyes lingering on her body. "Anytime, Lin Xia. I'll be watching your progress closely."
She walked away without looking back, but her mind was racing. The feeling of his massive cock pressed against her ass stayed with her the rest of the day.
The next day, during the optional chess club session in the quiet activity room, Lin Xia was sitting alone at a table, using her phone to look up rules and strategies. She was wearing her usual university uniform — white blouse and short pleated skirt — her long legs crossed elegantly.
Mr. Kane entered the room. He was alone with her. The door clicked shut behind him.
"Having trouble understanding the rules?" he asked with a charming smile.
Lin Xia looked up and nodded. "A little. I'm trying to learn."
He walked over and sat beside her. "Why don't I teach you properly? It'll be easier if you sit on my lap. That way I can guide your hands and show you the moves up close."
Lin Xia hesitated for half a second, then stood up. She let him pull her onto his lap.
The moment she sat down, she felt it — his thick, heavy cock pressing against her ass through the thin fabric of her skirt and his sports shorts. It was already semi-hard and felt enormous. The loose sports dress did nothing to hide how big it was.
Mr. Kane wrapped one arm around her waist, the other hand covering hers on the chess piece.
"See? Like this," he said, moving her hand. His voice was calm, but his hips shifted slightly, pressing his BBC more firmly against her ass cheeks.
Lin Xia felt the heat and size of it. It was hot, thick, and throbbing. She didn't protest. Instead, she wiggled her butt a little, rubbing against him as if adjusting her position.
Mr. Kane's breath hitched. "You're a fast learner," he said, his voice dropping. "Keep moving like that and you'll understand the game even better."
She continued to "learn," wiggling her ass slowly on his lap. His cock grew fully hard, the massive length now pressing directly between her ass cheeks.
He opened his legs wider, pointing his BBC more firmly against her. Every few seconds he gave a small, subtle thrust, rubbing his hard cock along her ass crack.
"Careful with the black pieces," he whispered, his hand sliding up to cup one of her breasts through her blouse. "They swallow the queen if you're not careful."
His fingers squeezed her breast, pinching her nipple through the fabric.
Lin Xia moaned softly. "Ah… Sir…"
He massaged her breast openly now, squeezing and kneading it while his other hand stayed on the chess piece, pretending to teach her.
"Always beware of the black piece," he continued, his voice filthy. "It can pin the queen down… make her wet… make her cum."
He pinched her nipple harder. Lin Xia moaned louder, her body trembling on his lap.
Seeing she was getting bold, he grew bolder. His hand slid down, lifted her skirt, and slipped inside her panties. He found her pussy already soaking wet.
"Look at this," he groaned. "The queen is already dripping for the black piece."
He slid two thick fingers inside her pussy and started thrusting them slowly.
Lin Xia's head fell back against his shoulder. She moaned openly.
"Ahh… Sir… your fingers…"
He fingered her faster, curling them inside her while his thumb rubbed her clit. His hard BBC kept rubbing against her ass.
She came hard on his fingers, her pussy clenching and squirting a little. Her legs shook, toes curling.
Mr. Kane didn't stop. He kept fingering her through the orgasm, whispering dirty words in her ear.
"Good girl… cum for your teacher… let the black piece take the queen…"
Lin Xia was breathing heavily, her body limp on his lap, completely lost in the pleasure.
The chess lesson had turned into something far more dangerous.
