Luis used all the ten cards he had just received without hesitation, with the same electronic voice in his mind: "Use 2 D-level male body enhancement cards and 2 D-level penis enhancement cards on the host, and 2 D-level female body shaping cards, 1 D-level private parts beautification card, 1 D-level breast beautification card, and 2 D-level favorability enhancement cards on Yuna."
The activation of the card did not have any special effect. Apart from feeling that his body became more relaxed, Luis had no other feelings.
He looked at his cock, which had been hardened by his girlfriend, and Yuna, who stood up to ride on him, but did not find any obvious changes visible to the naked eye. Luis began to doubt how big the "slight change" mentioned in the card manual was.
Yuna didn't notice her boyfriend's disappointment and rode on Luis with full expectations. She felt an unprecedented tingling sensation in her pussy and was eager to be filled with something. Luis's physical strength was average, and they often used the woman-on-top position.
She held the cock against her pussy and sat down, her buttocks sinking to a familiar height. In the past, the glans should have been at the vaginal opening at this time, but today, Yuna couldn't help but let out a scream of "Ah!" as most of the glans was inserted directly into her pussy.
"Hiss—" Luis also took a sharp breath. The pleasure from the glans was overwhelming, completely different from before. Is this the effect of the card?
He couldn't help but marvel at this "slight" improvement. Though hard to detect visually, the actual effect was outstanding.
"Hubby, you're so bad… You secretly pushed your dick into my pussy." Yuna punched Luis's chest with her pink fist and pouted. "My little pussy is so sore because of your big dick. You have to compensate me…" She thought Luis had deliberately thrust deeper and never imagined his size had changed.
"How do you want your husband to compensate you?" Luis stroked his girlfriend's thigh, searching for the slightest improvement.
Yuna twisted her waist, feeling slight resistance this time. After a few adjustments, his penis slid most of the way in. Normally, it would take only two or three strokes to reach this point.
"I want my husband to take pictures of Yuna's lewd appearance and post them on his Twitter!" This was Yuna's request. Being filmed in obscene poses amplified her pleasure. Before dating Luis, she would record herself masturbating, and after getting together, she insisted on filming their sex sessions.
"Okay!" Luis agreed immediately. While enjoying Yuna's riding, he picked up his phone and started recording.
To his surprise, Yuna's breasts bounced rhythmically under the camera, far more enticingly than before. He quickly compared it to past recordings same position, yet never this hypnotic. Was this the card's effect?
But her breasts hadn't visibly grown!
Luis kept filming with one hand while groping her bouncing chest with the other.
"Ah! No!" Yuna gasped. Despite her protest, her breasts pushed forward eagerly, and her riding grew wilder. "Husband, do you want to play with the little slut's tits? You're so good! Not only filling my pussy but also molding my tits!"
Luis kneaded her breasts obsessively, less for play and more for inspection. They weren't drastically larger but felt fuller, the flesh silkier. He couldn't stop touching them.
Whether it was his own enhanced stamina or Yuna's optimized body, the D-level cards delivered. The changes were subtle but transformative where it mattered.
Oh, right private parts optimization! Luis shifted the camera downward, focusing on their joined genitals. His shaft glistened with her fluids, her labia stretched around him.
Yuna shuddered at the attention, arousal surging hotter than ever.
"Husband… look at my little pussy, dripping just for your big cock~~" She shifted from kneeling to squatting, spreading her legs wide and parting her pubic hair to expose her slick entrance.
Luis leaned closer. The usual darker pigmentation around her thighs and labia seemed to be fading.
He pressed his thumb against her swollen clit, rubbing firmly. Yuna jerked violently, her hips pistoning erratically. Luis gritted his teeth, fighting the urge to cum too soon.
"Ah! Hubby~ You can… cum inside! This slut wants… wants to swallow it all…" Yuna moaned, convinced he was close. Compared to past sessions, this one already felt incredible.
But to their shock, Luis didn't cum. His cock remained rock-hard, plunging in and out of her relentlessly.
"Want my cum? Should've said sooner." Thrilled by his newfound stamina, Luis tossed his phone aside, pulled Yuna down, and gripped her ass. "Let's see how hard your husband can wreck this slutty pussy."
"Yes—wreck me! I'm your slut, ah…" Yuna kissed him feverishly, her walls fluttering. For the first time, she wasn't faking her climax—she was barreling toward something unimaginable.
Luis lifted her hips and hammered into her, their skin slapping loudly. The room filled with the sounds of flesh, his ragged breaths, and her broken whimpers.
Long after, Yuna lay limp atop Luis, spent. It took her minutes to recover from the overwhelming pleasure. They stayed silent, her finger lazily tracing circles on his chest.
"Luis..." Yuna's tender voice sounded extremely obedient.
"Um?"
"You were awesome just now!"
"Um!"
"You almost broke my pussy."
"Hmm~" Three identical replies in a row, but with different tones, expressing different emotions.
"It's the first time I've been fucked so comfortably..."
"Um."
"Originally, I wanted to break up after we did it tonight." Yuna said something that had been weighing on her heart for a long time.
"..." In fact, Luis had a premonition that he could no longer satisfy his sex-addicted girlfriend, and thought that breaking up might be good for both of them.
"Now I feel so stupid, Luis, can you please forgive me..."
"Yeah." Luis forgave Yuna without thinking too much, because he knew that it was not her fault. His girlfriend's sex addiction was too strong, and he could not satisfy her.
