My name is Jia, and I am nineteen years old, a fresh college student. In my family, besides myself, there is an older sister who is several years my senior. She married just last year. My brother-in-law, Mark, isn't exactly a conventional hunk, but he possesses a magnetic charm that makes me wonder how he ever fell for my sister. After all, my sister isn't particularly striking; she is conservative and lacks Mark's outgoing, bold energy. She is, however, incredibly gentle—perhaps that is what captured his heart. She is the quintessential devoted wife and mother. Currently, since her place is close to my university, my sister, Mark, and I all live together. It’s a perfect arrangement: I have someone to look after me, and we save a fortune on rent.

"I'm so annoyed!" I huffed, throwing the door open and tossing my bag onto the sofa. If you want to know why I'm fuming, it's because that plain girl in my class had the audacity to mock me, claiming I lacked charm and was a virgin simply because no boyfriend had appeared yet. For the record, my standards are just a little bit higher than most; I simply haven't found a man worthy of my maidenhood.

And it’s not bragging to say that while I might not be the delicate, fragile type of beauty, I am radiant, elegant, and incredibly sultry. When I walk down the street, men can't help but whistle at me. My figure is especially captivating; my breasts are large and lush, yet they possess a perfect, firm lift even without a bra. My small, rosy areolas are accented by two pink nipples that tilt slightly upward. Every time I step out of the shower, I spend a long time admiring myself in the mirror. I am utterly satisfied with my body.

"Sister, I'm home!"

"Oh, Jia, you're back!" Mark emerged from the bedroom. "Your sister has to work late again tonight; she won't be home."

My sister is a workaholic. Her office is far away, so whenever she pulls overtime, she stays overnight. This means Mark and I are often the only two people in the house.

Drenched in sweat from the day, I didn't even stop to eat. After greeting Mark, I ducked straight into the bathroom to wash up.

As I sank into the warm, comfortable soak of the bathtub, my thoughts drifted to Mark. Honestly, my sister is so lucky to have such a wonderful man, yet she spends all her time working. I couldn't help but wonder if Mark ever finds it difficult to stay disciplined when he's alone. *Hehe.* A decision formed in my mind: I was going to let Mark be the one to take my virginity. It would be a waste not to take advantage of such a magnificent resource right under my nose. Thinking of his powerful, muscular build made my cheeks flush. I wondered if he was just as magnificent below the belt.

After dinner, Mark retreated to the study to browse the internet. In my room, I shed my underwear and changed into a tiny camisole and a micro-skirt. This skirt is my secret weapon; it’s so short that one wrong move could lead to a scandal. As for the camisole, it barely covers my chest, leaving my pert little nipples almost entirely exposed.

I knocked softly on the study door and slipped inside. Mark was indeed busy on his computer, completely absorbed in what he was watching. He didn't even look up, but that wouldn't stop me. With a coquettish giggle, I leaned in close. "Mark, can you teach me how to play this game?"

As I spoke, I began to act spoiled, nuzzling and rubbing my body against him. Perhaps because I was always so affectionate, he didn't find it odd at first. While watching his reaction closely, I pressed the soft mounds of my breasts against his arm.

Mark’s body stiffened for a moment, but he soon relaxed, pulling me to sit on his lap. He took my hands in his, ostensibly to teach me the game.

It was obvious he wasn't focusing on the screen. His eyes were glued to my chest from behind. Every time I shifted my weight, my breasts grazed him. Beneath his hips, his manhood grew hard, pressing firmly against my backside. As I began to grind my hips against him, the heat intensified. His breathing grew heavy and ragged, the sound vibrating right against my ear.

I turned my head intentionally, letting my lips brush against his. Finally, Mark lost his restraint. He wrapped his arms around my waist and pulled me into a fierce, hungry kiss. I opened my mouth eagerly, welcoming his tongue as it danced with mine. The kiss sent a wave of heat through my entire body, and our tongues became hopelessly entwined.

His hands were far from idle. One hand slid beneath my tiny skirt to knead the soft flesh of my buttocks, while the other hiked up my camisole to reveal my proud, swelling breasts.

Leaving my lips, he used both hands to pull the camisole up and over my head, fully exposing my perfect bust. Under his intense gaze, my pink buds stood even more erect. The dampness between my thighs became undeniable. Unable to contain myself, I turned around and hiked my right leg up, straddling him. Mark, finally recovering from the shock of seeing my naked breasts, began to nibble and suck on my nipples while his hand wandered up the sensitive skin of my inner thighs.

"Jia... your breasts are so beautiful," Mark murmured against my skin, his voice thick with desire. "It's like they were made to seduce men."

"And how do they compare to my sister's?" I teased.

"You... you're far superior. You're the most beautiful woman I've ever seen. You're a little temptress sent by heaven just to drive me crazy!"

His hand had already slid beneath my skirt, finding the moisture between my legs. My skin felt like it was on fire. I could only writhe against him as his fingers delved into my secret place. A tremor ran through me, and a soft moan escaped my lips.

"Ah... Mark... I want... ah..."

"You little slut... did you come here without panties just to seduce me?" Mark swept the items off the desk with one motion, lifting me onto the surface. He spread my legs wide over his shoulders and leaned down, his face inches from my core. His fingers parted my tender folds. "Let's see how you deserve to be punished."

The sensation of his hot breath against my most sensitive spot was overwhelming. A sensation unlike any other washed over me. I gripped his head tightly, my legs clamping around his neck. A rush of fluid escaped me as I met my very first orgasm.

"Is that all?" Mark chuckled softly.

"How about this?" He began to tease my sensitive little pearl with his fingertip.

The body that had just relaxed from the climax instantly tensed up again. Loud, uncontrolled moans spilled from my mouth as the intense pleasure threatened to overwhelm my senses.

"Mark, please... hurry..."

"Say it," he commanded. "Say, 'Big brother, please fuck me. Use your big cock to ruin this little slut!'"

His tongue was already exploring my tight, narrow passage, while his hand returned to my breast, squeezing and pinching my sensitive nipple. My entire body flushed a deep crimson as I cried out.

"Please, Mark! Fuck me!"

"Use your big cock and kill me... fuck me hard!"

Mark grabbed my hand and guided it to his massive, throbbing member, forcing me to grip it.

"It's so big..." I gasped, staring in awe at the magnificent length of him.

With a proud grin, he thrust himself deep into my body. Though he entered me with great care, the sharp sting of losing my virginity made my whole body freeze. He whispered soothing words, and I could tell how hard he was working to restrain himself; sweat beaded on his forehead. Finally, he let out a guttural roar.

"Jia, I can't hold back anymore!" He began to hammer into me with primal intensity.

The initial soreness was fading, replaced by a deep, throbbing ache that felt incredibly good. Soon, a numbing sensation took over, and instinctively, I began to lift my hips to meet every one of his powerful thrusts. He knew exactly how to move, driving me toward a second peak of pleasure until I climaxed once more.

"Jia, your little hole is so hot and tight... I could do this forever!"

"My wonderful man... ah... then just fuck me for the rest of my life... Jia will always be your little slut..."

With one final, powerful surge, Mark thrust deep and released a hot torrent of seed into the very depths of me. The warmth made my whole body shudder, sending me into a final, pulsing orgasm.

As he slumped against me, I felt his member begin to harden once more inside me. My newly opened core reacted instinctively to the pressure. Seeing my eagerness, Mark scooped me up and carried me to the large bed in the bedroom. A new round began, filled with my wanton cries and dirty talk. We didn't stop there; we finished the night with another frantic encounter in the shower before finally collapsing into bed to sleep.
