Luis was brushing his teeth slowly in the bathroom, looking at himself in the mirror and sighing silently. The naked man in the mirror was in his early twenties, with an average build, no well-defined muscles, and a listless penis between his legs.
He was still in college, a homebody and a lazy person. He usually played with his phone and computer, surfing the internet or gaming, or being dragged by his girlfriend to go shopping.
Yes, the ordinary Luis had a girlfriend, a fact regarded as an incredible miracle by his classmates. Though Luis's girlfriend was just an unremarkable girl from the same school, this was rare in today's university campus where there were more wolves than meat and society was extremely materialistic.
His classmates secretly speculated, with theories like "the one who takes over" or "the master's mission" running rampant, serving as gossip fodder for quite some time.
"Baby, hurry up..." Yuna's voice urged outside the bathroom, "Why does it take so long to shower?" Hearing his girlfriend's impatience, Luis didn't react, still brushing each tooth carefully. Today was Saturday. After shopping and dinner with Yuna, they had gone to a hotel and booked a room. This brought back memories of how they had gotten together.
Aside from gaming, Luis enjoyed surfing the web and following various bloggers. There were female bloggers who liked to express themselves solo, those trained in various ways by their masters, and those selling lewd photos all kinds.
Yuna had been a female Twitter blogger Luis followed. However, due to her average figure, she had few followers, and Luis was one of them. Initially, the two weren't close, but Luis recognized her from one of Yuna's updates (before she was a blogger), realizing they were classmates.
After an unexpected in-person meeting, their relationship fast-tracked, and they soon became a couple. This was the truth that baffled their classmates, not the wild speculations.
It wasn't that Luis lacked interest in sex. Early on, he had been thrilled by Yuna's body. Yuna also had a strong libido, and they indulged daily.
After the initial excitement faded, they sought thrill in various places. Over time, Yuna's desires grew harder to satisfy, and Luis struggled to find pleasure, even feeling the frustration of a middle-aged man's helplessness prematurely. Hence, his current lack of urgency and disinterest.
A few minutes later, Luis finally stepped out of the bathroom. He didn't dare keep Yuna waiting too long.
As he emerged, he saw a woman kneeling on the bed, her buttocks raised toward him, one hand between her legs, fingering her wet pussy with a "squelch... squelch..." sound. It was Yuna.
"Baby, what took so long? Don't you want Yuna's pussy? Today's my ovulation day. Can you knock me up?" Hearing her boyfriend's footsteps, Yuna lost control at the thought of being fucked, fingering herself even harder.
Luis knew his girlfriend was just horny. After they got together, Yuna had taken birth control pills proactively. She disliked condoms, so they never used them.
Luis walked over, placing one hand on her butt and gripping his half-asleep cock with the other. He rubbed the glans against her wet slit, stroking impatiently.
Yuna didn't notice her boyfriend's lack of enthusiasm. Face buried in the bed, she arched her back and moaned, "Ah! The big cock's teasing my pussy! Hubby, put it in already! Yuna's pussy wants to be stuffed!"
Growing impatient, Luis raised his hand and smacked Yuna's butt, ordering her harshly to stop shaking. This time, she obeyed, her ass stilling—though the spank sent a thrill through her, a trickle of arousal dripping from her cunt.
Luis had recently discovered his girlfriend's slight masochistic streak, though it wasn't deep. A smack on the ass was just enough to spice things up for this "old couple" who'd been together over a year.
Finding a bit of momentum, Luis thrust his hips forward, sliding his glans into her well-trodden pussy.
Ding!
"Host detected initiating intercourse for the thousandth time. Activating Sex Lust Deck binding protocol. Will host bind?" A pleasant female voice echoed in Luis's mind.
A system?
Sex Lust Deck?
What was this?
A thousand times?
Had he and Yuna really done it a thousand times?
In just over a year?
No wonder he felt nothing for her now.
A year, excluding her period, meant fucking his average-looking girlfriend four to five times a day on average. No one could keep that up!
"Repeating: Will host bind? The Sex Lust Deck allows draws based on intercourse quality. Please decide before countdown ends. Timeout will forfeit. 3... 2..."
The voice pressed, giving only three seconds. Before Luis could process it, only one second remained.
"Bind! Bind!" Luis hurriedly confirmed the binding. Although he didn't know what had happened, as a veteran surfer, he had seen plenty of systems and plug-ins in novels.
He just never expected such an incredible thing to happen to him one day. Binding to the system and becoming the male protagonist, this kind of trope, even if it was just a prank, what did he have to lose?
"Binding successful. Sex evaluation function activated. Congratulations, Host. Please work hard to complete this sexual encounter. The system will determine the card pool level based on your performance."
Was this a successful binding?
Could it be a trap?
Luis felt like the system had deliberately denied him time to think, forcing him into a hasty decision. Now that the binding was complete, he didn't feel any different, which only made him more suspicious.
"Husband… why did you stop?" Yuna felt unbearably empty, her stretched entrance left unfilled. She pushed her hips back, trying to coax his cock inside, but found it still too soft to penetrate.
"Husband? Isn't Yuna sexy enough? Why isn't it hard? Do you want Yuna to suck it?" She turned around, kneeling before Luis, and took his half-hard length into her mouth.
The warmth enveloping him snapped Luis back to attention. Seeing the sadness in his girlfriend's eyes, he quickly reassured her.
"Ah… so good! Yuna's mouth is the best. How about I take a picture of you sucking my cock and post it on your Twitter later?"
"Mmm… slurp… yes!" The mention of photos made Yuna suck harder.
When they'd first gotten together, they used to film every encounter, uploading the clips to Yuna's Twitter, amassing quite the following. Over time, Luis had grown bored of it, but occasionally indulging her still made her happy.
Luis grabbed his phone, angling it toward her face.
"Look at the camera… Good, now stick out your tongue and lick… Perfect. Wrap your lips around the head and suck hard… Feels amazing! Ah—got a great shot!" He showed her the screen—her lust-drunk eyes, the glistening thread between her tongue and his cock, lewd beyond words.
Pleased, Yuna redoubled her efforts, and soon, Luis was fully hard. She pulled back, panting. "Husband's so big today… Yuna's pussy wants you inside…"
Luis pulled his cock free, slapping it against her cheek, smearing her skin with spit. This was his tell—when he was truly in the mood. His girlfriend's eager mouth had helped, but more than anything, it was the thrill of the Sex Lust Deck that had him fired up.
"How do you want me to fuck this little cunt?" He shoved his cock back into her mouth, forcing her head down until she gagged.
"Ghk—! Ugh—!" Yuna's throat convulsed, her lungs burning. Her mind fogged, pleasure and suffocation blurring together.
Luis finally pulled out, letting her gasp for air. Before she could recover, she begged, "I want… I want Husband to… lift Yuna's legs… put them on your shoulders and fuck—"
Luis was in peak form, his stamina seemingly renewed—maybe a side effect of the system?
He shoved her onto the bed, spreading her legs over his shoulders. Yuna's breath hitched, her pussy clenching as a rush of slickness soaked her thighs.
Luis dragged his cock along her folds, teasing, watching her squirm.
"Please… Husband… just fuck me! Ruin me! Don't tease—ah!" Her plea cut off as he slammed inside, hilting himself in one brutal thrust. Her back arched, mouth open in a soundless scream.
He didn't hold back. Each snap of his hips punched the air from her lungs.
"Ah! N-no… too… ngh! Too deep—!" Yuna babbled, overwhelmed. It had been so long since he'd fucked her this hard. "Husband… love me… ruin me! Ah—! Ngh! W-wait—!" Tears spilled as pleasure wracked her body.
Luis was relentless. One hand groped her breast, the other circling her clitoris. Yuna tried to resist—not his touch, but the unbearable pleasure. Soon, her hands joined his, pressing his palm harder against her nipple, spreading her pussy wider for him.
Yuna wasn't conventionally perfect her B-cup breasts, soft belly, and thick thighs weren't model material. But her round, plump ass was Luis's weakness, especially when he took her from behind.
As his thrusts grew erratic, Luis felt his climax building. He wanted to last longer, but his stamina had limits. With a grunt, he leaned forward, pistoning into her with desperate, final strokes.
