Rex's fingers went inside her, two at a time, and filled her completely.
"AAHHHHHNN~!" Mara screamed as pleasure washed over her like a huge wave, bending her back off the mattress.
Her vagina tightened around his fingers, holding them tightly as her orgasm hit her with brutal force. "Oh fuck, oh fuck, oh fuck!" she screamed, her hands clawing at the sheets and her body shaking violently.
"W-What...? Rex's fingers... they're bigger than my husband's cock... how is this even possible...?" Mara said in her mind. "And with just one shove... he already made me cum hard..."
Rex's fingers moved quickly and deeply, fucking her while his thumb kept working her clit through the aftershocks. "That's it," he grunted, his voice heavy with desire. "Take it and feel it while you moan."
"Take everything you desire, just like a frustrated wife would." He could feel her walls tightening around him and milking his fingers, which made him feel hot in his stomach.
"Hahahahaha! I can't believe a wife like you has a fucking tight pussy. And it's very wet on the inside."
"You were meant to do this, right?"
Mara had another orgasm that was even stronger than the first. Her body went stiff, and her toes curled up as pleasure so strong it almost hurt washed over her. "Ahhhn~! Fuck~! It's so good...!"
"Rex...! Rex...!" she yelled, her voice breaking. "I can't...stop cumming... urggghhhh!"
"Good," he said in a low voice, his fingers still moving. "And this is just the opening."
"I'll show you something that will make you cum even more!" Rex pulled down his pants and underwear just to show her his massive cock that was twitching because it had been holding all of his libido for days because he hadn't fucked anyone in this world.
Mara's eyes widened seeing a massive cock for the first time, and it's out of its league compared with her husband's limp cock. "N-No way... that...that's too big...!"
Mara's whole body went stiff the first time Rex's cock touched her entrance. It was thick, a lot thicker than anything she'd ever felt before.
It was shocking just how big it was, but it was more than that. The hardness of it, the heat, and the way it throbbed against her most sensitive skin made her breath catch in her throat.
"Rex..." she said, her hands gripping the sheets so tightly that her knuckles turned white.
Her eyes were wide open, and she was staring up at the ceiling as she tried to figure out what was going on. "It's... it's so..."
He finished for her, "Massive? I know, I'm proud of it." His voice was rough with laughter and desire.
His hands were still on hers, one on each wrist, keeping them pinned above her head while looking at her whole naked body, where he could see her massive breasts. "Whoa~! Look at those massive tits that I love~!"
"I once masturbated before going to sleep while imaging those, you know...?"
Mara blushed while looking away. "Th...thank you." And somehow it made her happy that someone showed desire for her body after so long.
"Mara, you need to calm down for me." Rex slowly pushed her cock into her entrance. "Ease yourself so that my cock can get inside."
But she couldn't calm down. Her body was shaking, and her pussy was involuntarily tightening around the head of his cock, which was only barely inside her.
The sensation of the stretch was intense, bordering on pain, yet the intense pleasure left her breathless. "I can't," she said, her voice breaking. "It's too much..."
"Too much?" Rex laughed, and the sound was dark and knowing.
"Then let me make your pussy adapt to its size..." He pushed a little harder, and Mara felt her walls stretch around him as her body slowly and desperately tried to make room for him.
"NggghhhhH~!" Mara covers her eyes with one hand, but her mouth can't lie that she's enjoying it.
"Your pussy is really tight, Mara...it felt like you're a virgin." His thumb rubbed her clit, and the feeling made her gasp. "Has your husband ever made you feel this full? And this fully stretched?"
The question hit her like a slap, and the answer came out as a cry. "No... oh god, no..."
Her hips moved as she tried to get used to the intrusion, and her body instinctively wanted more even though it hurt. "He's... he's never been this... big..."
Mara thought. "His cock... it's so fucking good that it made me... forget about my husband's limp cock...!"
Rex's hands got tighter around hers, but they didn't hurt. "Heh. Of course not," he said, his voice dropping to a low growl.
"He's a loser, Mara."
"A sad, weak loser with a small cock who doesn't deserve a woman like you." He pushed in another inch, and Mara screamed, her body shaking.
"NNNGGGHHHHH~!" Mara was still covering her moan while biting her mouth.
"He can't make you happy, and what's even worse is that he can't make you feel this way...but I can." Rex smirks.
The words should have hurt her feelings and made her mad. But instead, they sent a dark thrill through her that mixed with the overwhelming pleasure of his cock opening her up.
"Rex..." she said, her voice weak and pleading.
"Say you need it," he said, moving his hips slowly and on purpose. "Tell me you need me to fill you up."
"I need it," she gasped, her body arching up to meet his thrust. "I need you to be inside me."
"I need you to have sex with me..." Mara stops covering her face so that he can see her horny face of a married wife.
"Heh... finally giving in, huh?"
Rex let out a low groan as he pushed himself all the way inside her, losing control for a moment.
"OOHHHHHHH~! FUCCCKKKK~!" Mara screamed, and the feeling of being completely filled by him pushed all other thoughts out of her mind.
She could feel every inch of him, every ridge and vein pressing against her inner walls as her pussy clenched around his length. "Ohhhh~! Fuckkkk... yes... it's fucking good... ahhhnnnn... nggghh...!"
"Heh! With just one thrust and you're already cumming like the frustrated wife you are."
"Ohhhhh... yes... more... moreee..." Mara starts to show more of her horniness in her expression. "I want to cum more..."
"Fuck," Rex said, his forehead against hers.
He let go of her hands and grabbed her hips, digging his fingers into her soft skin. "You're so fucking tight!"
"I can feel you squeezing me like a fist!" He started to move, pulling almost all the way out before slamming back in.
"AAHHHNN~!!! OOHHH~!" Mara's scream was raw and desperate.
"That's it, keep moaning like a heated bitch you are and take my dick whole!"
"Show me how much you've been wanting it."
PLAP! PLAP! PLAP! PLAP! PLAP!
His thrusts were hard and fast, and each one went deep inside her. Every time she hit something, Mara's body bounced, her breasts swayed, and she gasped for air.
It felt so good that it was almost too much, but Rex's hand found her clit again. The feeling of his cock fucking her and his thumb circling her sensitive bundle of nerves pushed her right to the edge.
"OHHHHHHHHHH~!" Mara screamed loud and starts squirting. "YEESSSS~!"
"Rex... I'm... I can't..." she gasped, her words barely making sense.
Her hips met his thrusts, and her body moved with him even though her mind was having a hard time processing all the feelings. "It's too much... oh god, it's TOO MUUUCH...!"
"Too much is good for a frustrated wife like you," Rex growled in her ear, his breath hot on her skin. "You were born for this."
"You were made to take a man's cock for the whole day!" He pushed his thumb harder against her clit, and the orgasm hit her like a wave.
"AAHHHNNNN~!"
"Cum more to me, Mara."
"Cum on my cock like the little slut you are!"
Her body shook around him, and her pussy tightened as waves of pleasure washed over her. Rex's cock got even bigger inside her, and he groaned as he moved around in a strange way.
"That's it... squeeze me... milk me..."
PLAP! PLAP! PLAP! PLAP! PLAP!
"Ahhnn~! Ahhh~! OHHHHH~!" Mara keeps on moaning nonstop like a heated bitch.
"Ohhh~! Here comes my first shot! Should I do it inside or outside?!" Rex fastens up his pace until Mara keeps on moaning and can't say anything to him.
"AAHHH~! AHHNNN~! OUT...side...! Inside...! AHHHNNN~!"
"Alright~! If you really want it on the inside. Don't blame me if you get pregnant~!"
His cock throbbed and pulsed deep inside Mara's tight heat as Rex experienced an orgasm. "I'M CUMMING INSIDE!!!"
He shot out thick, powerful spurts of hot cum that filled her completely. "N-NOO---AAAHHHHHNNNNNNNN~!!!"
SPLUUURRRRTTTTTT~!
Mara's body went stiff, and her eyes rolled back in her head as the sheer amount of his release made her feel overwhelmed. Her tongue hung out of her mouth, her jaw was loose, and her body shook with the aftershocks of her own orgasm as she felt him fill her.
"Ohhh... hoohhhh... ohhhh..." Mara starts breathing hard and feels the semen all the way inside her deepest.
"Fuck... fuck..." Rex moaned, and his hips jerked with each beat of his cock.
"Goddamn, you milked me so much!" His hands were so tightly around her hips that his knuckles turned white, and his fingers dug into her soft skin as he emptied himself in her.
When it was finally over, he fell forward onto her, his weight pushing her down into the mattress. His breathing was uneven and ragged.
For a long time, the only sound in the room was their heavy breathing. After that, Mara moved around under him, her body still twitching with pleasure.
"R-Rex..." she said in a hoarse, dreamy voice. "Please... stop..."
"I need a break..."
Rex raised his head and looked down at her with dark, hungry eyes. His cock was still deep inside her, and it twitched every now and then.
He could still feel her walls tightening around him. "Break?" he said again, this time in a low, amused voice.
"We've only done one round, Mara."
"You think you can take one more?"
"W-What...? I thought when a man cum once, he can't go again...?"
"Hahahahaha! I'm not your fucking husband! I'm Rex fucking Rexilion, and I can make it through the morning if you want!"
She blinked up at him, her eyes still glazed with pleasure and her body slick with sweat. "N-No way..."
"I... I can't..." she said softly, but even as she said it, her pussy tightened around him again, as if her body was going against what she said.
Rex laughed and pulled out of her with a wet sound that made her gasp. He sat up, and his huge cock was still hard and throbbing, shining with their fluids.
He held his shaft in one hand and stroked it slowly down its length. With the other hand, he moved to cup her swollen, sensitive clit. "Look at this," he said in a commanding voice.
"Look at how fucking hard I still am!"
"Do you really think I could stop after just one round? After making you come like that?"
He stroked himself again, and Mara's eyes got bigger as she watched. The size, thickness, and way it pulsed and twitched made it too much to handle.
Her husband's penis had never looked like that before or been that big. This was real, and this was the true strength of a real man's cock.
"Ten rounds," Rex said in a low growl. "I'm going to fuck you for ten rounds, Mara."
"And you're going to take all of them like the good slut you are." He kept stroking his cock with his fingers, and the head turned an even deeper shade of red. "Unless...you want to show me I'm wrong?"
"And you want to prove to me that you're not the needy little slut I know you are."
His eyes were on hers, and Mara could see the challenge in them. Her body was still shaking, her pussy was still swollen and sensitive, but the idea of saying no to him and letting him down made her feel darkly excited.
There was also something else. Something she didn't want to say. A part of her wanted to see how much he could handle and how much pleasure he could give her.
"Ten rounds," she whispered, her voice so low that it was hard to hear.
"After that... promise me to forget about everything that has happened today!"
Rex's smile grew wider, and it looked like he was going to eat someone. "Good girl, and I promise."
He got back in between her legs, and his cock was pushing against her entrance. "Let's begin counting!"
