Ethan woke up early on his first day at the new job, his body buzzing with excitement. The Sex Beast Upgrade System had changed everything since that night with Lisa. His cock now measured seven inches, thicker and harder than before, thanks to the +1 inch boost. And his stamina? It felt endless, like he could go all day without tiring. He dressed in a crisp shirt and slacks, the fabric tight against his improved physique, and headed to the office building downtown.
As he stepped out of the elevator on the fifth floor, the system's voice chimed in his head, clear and commanding. 'New objective: Fuck the first woman you see in your office. Complete it to unlock the next upgrade: Increased Sensitivity for your partner.'
Ethan's heart pounded. His office was assigned to him a small corner space with a desk, computer, and window overlooking the city. It was barely 7 AM, the building quiet before the rush. He turned the key in the lock and pushed the door open, the scent of fresh coffee from the break room lingering in the air.
There she was. The cleaner, bent over his desk, wiping it down with a rag. She was thick, her body curved in all the right places. Her uniform a simple blue smock and pants clung to her wide hips and that big, round ass that jiggled slightly as she moved. Her skin was a warm brown, hair tied back in a ponytail, and she hummed a soft tune under her breath. Ethan guessed she was in her late thirties, with full breasts straining against her top and thighs that looked powerful.
He closed the door behind him, the click loud in the silent room. The woman straightened up, turning with a start. 'Oh, sorry, sir. I didn't hear you come in. I'm Maria, the morning cleaner. I'll finish up quick and get out of your way.'
Ethan's cock stirred in his pants, already half-hard from the system's command. He locked eyes with her, a grin spreading across his face. 'No rush, Maria. Actually, stay a bit. I could use some... help starting the day right.'
She blinked, tilting her head. 'Help? Like with the desk or something? It's all clean now.' Her voice had a slight accent, warm and inviting.
He stepped closer, his gaze dropping to her curves. 'Not with the desk. With me.' Before she could respond, he reached out and grabbed her wrist gently but firmly, pulling her toward him. Maria gasped, her rag dropping to the floor.
'What are you...' she started, but Ethan cut her off by pressing his body against hers. He could feel the softness of her belly and the heat from her skin through the thin fabric.
'The truth? I need to fuck you, right here, right now,' he said plainly, his voice low and rough. 'And I think you want it too.'
Maria's eyes widened, but she didn't pull away. Instead, a flush crept up her neck. 'Sir, this is work. We can't... oh god, your hands.' Ethan's free hand slid down to cup her big ass, squeezing the firm flesh. It overflowed his palm, soft yet toned from years of labor.
'Call me Ethan,' he murmured, leaning in to kiss her neck. She shivered, her breath hitching. 'And yes, we can. No one's here yet. Just you and me.'
She hesitated, then her hands came up to his chest, not pushing but gripping his shirt. 'You're bold. Never had a boss like this. But... okay. Make it quick?'
Ethan chuckled, his lips brushing her ear. 'Quick? With this stamina, I can make it last.' He spun her around, pressing her against the desk so her ass pushed back into his growing bulge. Maria moaned softly, arching into him.
He yanked her smock up over her head in one motion, tossing it aside. Underneath, she wore a plain white bra that barely contained her heavy tits D-cups at least, spilling over the edges. Her pants came next; he unbuttoned them and shoved them down her thick thighs, revealing white cotton panties stretched tight over her wide hips.
'Damn, that ass,' Ethan growled, slapping it lightly. The flesh rippled, and Maria yelped, then laughed.
'You like it? Most men do.' She wiggled her hips, teasing him.
'I love it.' He hooked his fingers in her panties and pulled them down, exposing her bare pussy and the dark curls above it. Her ass cheeks parted slightly, showing the tight pucker between. Ethan dropped to his knees, spreading her legs wider. He buried his face between her thighs from behind, tongue lapping at her folds.
Maria gripped the desk, her knuckles white. 'Oh fuck, Ethan! Your tongue... right there.' Her pussy tasted salty-sweet, already wet. He licked up and down her slit, then focused on her clit, sucking it gently. She bucked back, grinding against his mouth.
'You're so wet already,' he said, pulling back to slap her ass again, harder this time. A red mark bloomed on her skin.
'Because you grabbed me like that. Made me hot,' she admitted, panting. 'Don't stop.'
Ethan stood, unbuckling his belt. His slacks fell, and he kicked them off along with his boxers. His seven-inch cock sprang free, veined and throbbing, the head leaking pre-cum. He stroked it once, then pressed the tip against her entrance.
'Tell me you want my cock,' he demanded, rubbing it up and down her slick lips.
'I want it. Fuck me, Ethan. Fill me up.' Maria pushed back, trying to take him in.
He thrust forward, sinking his full length into her pussy in one go. She was tight, her walls stretching around his thickness. 'Shit, you're huge,' she groaned, her body trembling.
Ethan gripped her hips, pulling almost all the way out before slamming back in. The desk shook with the force. Her ass jiggled with each impact, the sound of skin slapping skin filling the room. He reached around to rub her clit, his fingers slippery from her juices.
'Harder,' Maria begged, her voice muffled as she bit her lip. 'Pound my pussy.'
He did, his hips pistoning faster. His balls slapped against her, and he watched his cock disappear into her over and over, coated in her cream. Sweat beaded on his back, but his stamina held no fatigue, just building pleasure.
Maria's moans grew louder. 'Yes, like that! Your cock feels so good stretching me.' She reached back, spreading her ass cheeks wider, giving him deeper access.
Ethan leaned over her, one hand tangling in her ponytail to pull her head back gently. He kissed her shoulder, then bit down lightly. 'You like being fucked like this? Bent over my desk on your first clean?'
'Love it. Never thought cleaning would lead to this,' she gasped, her pussy clenching around him.
He straightened, spanking her ass rhythmically with each thrust left cheek, right, left. The stings made her tighter, her body responding. 'Turn around. I want to see your face when you cum.'
Maria nodded eagerly, pulling off his cock with a wet pop. She spun, hopping onto the desk and spreading her legs wide. Her pussy glistened, puffy from the pounding. Her tits heaved as she unhooked her bra, letting them bounce free dark nipples hard and begging.
Ethan stepped between her thighs, grabbing her legs and hooking them over his shoulders. He slid back in easily, her juices making it smooth. Face to face now, he watched her eyes roll back as he bottomed out.
'Fuck, Ethan! Deeper!' She clawed at his arms, her nails digging in.
He obliged, grinding his hips in circles while buried inside her. His thumb found her clit again, rubbing firm circles. Maria's tits swayed with the motion, and he leaned down to suck one nipple into his mouth, teeth grazing it.
She arched, crying out. 'Suck harder. Bite it.' He did, nipping the sensitive bud while thrusting steadily. Her pussy fluttered, close to the edge.
'Cum on my cock, Maria. Squeeze me tight.' Ethan's voice was strained, his own release building but held back by his enhanced stamina.
'I'm... oh god, yes!' Her body seized, pussy spasming around him as she came hard. Juices squirted out, soaking his balls and the desk. She screamed his name, head thrown back.
The sight pushed Ethan closer. He pulled out suddenly, stroking his slick cock. 'On your knees. I want to cum on that big ass.'
Maria slid off the desk, dropping to the floor. She turned, presenting her ass red from spanks, cheeks spread. 'Cover me, boss. Give it to me.'
Ethan pumped his fist fast, the pleasure peaking. With a grunt, he erupted, thick ropes of cum shooting onto her ass. It dripped down her crack, pooling between her cheeks. He milked every drop, his cock twitching.
They both panted, Maria looking back with a satisfied smile. 'That was intense. You're something else.'
Ethan helped her up, handing her a tissue from the desk. 'Just the start of my day.' As she cleaned up, the system chimed again. 'Objective complete. Upgrade unlocked: Increased Sensitivity. Next objective: Seduce your boss secretary during the morning meeting. But beware someone's approaching the door.'
Ethan froze, hearing footsteps in the hall. Maria quickly dressed, grabbing her rag. 'I gotta go. See you around?'
She slipped out just as the knob turned. The Boss secretary, a stern woman in her forties, poked her head in. 'Ethan? You're early. Ready for the team intro?'
His cock still semi-hard, mind racing with the new objective, Ethan nodded. But as she stepped inside, he wondered how he'd pull this off without getting caught. The door clicked shut behind her, sealing his fate.
