Sperm Donation Clinic (long and very detailed, breeding, anticipation, cuckhold/cheating, height difference, too tight, rough) – Part 2

His massive form came down on her, and she now felt his full strength, as he took hold of her thighs and yanked her in a drag across the mattress up to his cock. Effortlessly, like she weighed nothing to him, and he could do with her as he pleased, Lukas set his cock up at her opening again to part it and fuck it into accommodating its size. He groaned, and she gasped, again, as he impaled her for the second time this afternoon. Once he began thrusting, he leaned forward to capture her lips with his, glide his tongue over hers, deepening their kiss as he stretched her hole with every thrust. Until he pushed in a bit too enthusiastically and she moaned suddenly into his mouth, and her palms found his abdomen, her body tensing up. “Careful,” she pleaded breathlessly, though his cock was growing even thicker inside of her, and trying to fit all of it to get up to her cervix would throw careful out the window.

“Do you know how tight you are?” he murmured in response, his expression focused as he breathed heavily into her neck. His large arms entrenched her, and one reached up to grab onto the head board. Lukas might have been able to keep his front on, but he was losing control with how forcefully her pussy was sucking him in, so hard there was more resistance to pull out than to push in. Already so tight, this feeling was mind-blowing. He tried to fight his own orgasm, but Nadia’s eyes were rolling back into her head as he slowed down and let her accommodate his size again. His grip on the headboard became so rough his knuckle turned white, while he reached underneath Nadia’s petite form to wind his arm around her back, and physically slam her down onto his size. She moaned out erratically as it finally stretched her open totally, her eyes rolled back into her head as he began rubbing up against her cervix, and every thrust was so heavy she could feel it in her belly. He never had been the type to jack-rabbit it, and instead fucked her through driving, powerful slamming thrusts up into her, ones that slammed the back of the headboard into the wall. Now that his entire length was inside of her, he fucked her without mercy. The true nature of his own desire surfaced now, as he beat into her animalistically; ruthlessly, not caring how sore her tight pussy might be from such an assault. It clenched down in spasms as she cried out. Lukas now used both hands to slam her down into his penetration, and her legs began to shake.

“That’s it, baby,” he cooed, focusing on her expressions as she lost herself in the bliss of spasming on his cock. “Breathe. Breathe through it.” His words, so gruff despite their guidance, served as a precursor to a deep and resonating groan from his own chest, sudden and prolonged, as he beat violently into her pussy. Her nipples, hard and puffy, were flinging out with the movement as her tits lobbed up and down her chest. It was then that he looked down, away from them, to try to hold onto one sliver of control, before he noticed the faded stretch marks lining her soft rounded hips, the small amount of cellulite dimpled into them. It sent him over the edge, and he groaned aggressively, as his balls suddenly tensed up without warning, and a flood of hot thick cum shot into her.

“Oh! Yes, Yes!” she suddenly panted out, shocked by the feeling, but quickly intoxicated with the bliss of him fucking his cum up into her. He didn’t stop. Of course, she’d done exactly what he told her. She wasn’t going to cum until he did. With powerful pulsations he shot another load into her, the release into her impossibly tight, warm walls like pure euphoria, and he didn’t stop cumming. He couldn’t stop, even as he fucked it so viciously into her that it began overflowing out of her hole. The feeling was so overwhelmingly intoxicating—his massive cock pumping more cum into her pussy than it could handle, forcing it into her cervix. While his tall, large form towered over her, his thrusts so powerful she was sure she wouldn’t be able to walk tomorrow. Nadia was nothing but instinct as her walls suddenly bore down—she screamed out, and her entire back arched as her pussy began milking the cum from his cock. All that was left inside of Lukas was squeezed up into her by that orgasm. It struck into her in waves of intense warmth, spreading through her entire body until her entire body began convulsing with the orgasm, in the same way her pussy was convulsing around his cum. It squeezed the cum from him, and she bounced up and down on it, meeting his forcefulness, and she squirted small spurts rhythmically with it, until finally her body fell limp, and she gasped for air. As she did so, Lukas kept his arm around her, pinning her to him.

He was going to make sure he delivered on his promise. “I’m gonna get you pregnant,” he murmured in assurance to her, smoothing down her hair out of her face, as he didn’t let up on his thrusts up into her. She was getting hazy and lulled, an exhaustion washing over her, and she couldn’t participate anymore. He lay her back down on the mattress, and fucked her as her cum soaked pussy could hardly take anymore. He could still feel her pulse on his cock. It was slowing, but he still fucked and used her hole until he had to cum again, and then drove her exhausted body up into his thrusts, forcing her to take as much cum as he could put inside her. She was so tired even her moans became softer and more weak, but then he felt it again—after he pulsed out another load of hot cum onto her cervix, his hand reached down to gyrate his thumb on her clit. Her moans became a bit more enthusiastic, and then her pussy weakly tensed up in its second orgasm, convulsing. Briefly, but pulling in all his cum all the same. Her pussy squeezed down so hard on him, it pulled him deeper inside of her, and he felt one final load throb from his tip onto her cervix, before he sighed, and laid down on top of her, breathing heavily.

For a long moment the two didn’t speak, and just caught their breath, until Nadia gave a lazy chuckle, a blissed out smile tugging on her lips. “Lukas,” she breathed, pushing her palms against him from below but unable to move him. “I have to go pee, can you get off me?”

Lukas then laughed, rumbling with it, as he hadn’t realized he was so heavy she couldn’t push him off of her. He rolled over onto his back, palm finding his abdomen, and closed his eyes. After Nadia used the bathroom she rejoined him, and somehow the ecstasy of what had just happened made her want to cuddle into him. His arm wound around her, and the two dozed off without intending to, Nadia fucked useless with his cum still leaking from her. Neither of them thought of their spouses.

A few hours later there was a knock on the door that startled Lukas awake. “Clinic’s closing. Wrap it up!” someone called through the door, and Lukas suddenly sat up, reached over across from her to get his watch from her bedside table. “What time is it?” she mumbled out tiredly, through a yawn.

“Oh, fuck.” He answered, and his fingers dragged through his dark curly hair. That was enough to get Nadia to push up onto her belly and look over at him. Her hair was a wild mane; her makeup smeared; between her legs she was a sticky mess. “It’s 1am.”

Nadia gasped, and shot out of bed, to rush putting back on her dress. “Oh, my god!” A panicked swipe into her phone and she had more missed calls and texts than she could wrap her mind around. The hazy memory of Lukas’ cock forcing open her pussy now throbbed in an echo for more as she realized they’d slept the entire evening together. Lukas followed suit, tired groan leaving him as he started pulling back on his pants. Nadia shook her head, trying to get herself together and wake up, as she blurted out. “I-I have to go.”

Lukas nodded, very nonchalantly, and stretched out his arms with another groan. The sight made Nadia bite her lip, and then she made a move for the door, but hesitated for a moment. She wasn’t supposed to do this. She knew she wasn’t, and she shouldn’t have wanted to, but she did. How could she not want to kiss the man goodbye who had just given her the best orgasm of her life? And hopefully impregnated her? She reached up on the tips of her toes, palms finding his upper abdomen, and he met her in the kiss she was trying to reach. As she tried to pull away, he secured a hand on her face. “I hope it doesn’t work.”

Nadia stared at him for a second, before asking dumbly, “What?”

“I hope it doesn’t work,” he reiterated, more firmly, as his hand dropped and casually reached down her dress, to take one of her nipples in his fingers, and gently tug on it.

The touch made her mouth fall open, resurrecting so easily with the lust he’d entrenched her in earlier. She almost made a move to kiss him again, but then realized how dark it was outside the window behind them.

“I have to go,” she restated, nodding as if to convince herself, and then left. In the car she realized she felt a bit nauseous, and her lower belly ached quite a bit. As she shifted around in her seat, she felt his cum push out of her, and the bruises he left on her legs sting with tenderness when she shifted pressure on them. She bit down on her lip, and waited in the car for much too long once she was home.

How could she tell her husband that she hoped the insemination didn’t work too, because she’d kill to fuck her sperm donor again?
