Student’s Pet
He’s got her right where he wants her. “I can’t remember the last time you raised your voice. I guess we’re both learning a little something new about you today, hm~?” His own throbbing prick is just as desperate for attention as Alphys is, and now that he’s satisfied he sees no need to wait any longer.
“Hey Alphys? Just to let you know…” He glides a hand along her body up to her neck, wrapping his hand around her throat, not squeezing but just using this as a show of the power dynamic that has just formed. “You’re mine now~” And with that he suddenly ruts into her, pushing his hips forward swiftly until he’s buried balls deep inside of her, her steamy walls wrapped around his shaft, the tip pushing past her cervix.
Though he meant to catch her off guard, he also succeeded in surprising himself too. Despite his talk, his inexperience means that he isn’t going to last very long during his first time, especially after ramming his hips into her. A cry of ecstasy escapes his lips as he pins his cock deep into Alphys’ womb, and without warning a flood of warm semen comes shooting out of him. It’s enough to leave her full of his cum, and some may even spill out if he wasn’t keeping it sealed up inside of her. He pants lightly, coming down from his very first orgasm, though his ffffffat cock doesn’t get any less erect. He’s just curious to see how she would react.
“Oh! O-ohh ghh- oh-!” She doesn’t react well. She is not exactly graceful, when she accepts Kris’s… “gift”, words failing as she falls into stuttering moans and slutty gasps. Everything lined up perfectly, not that Kris knew that; the filthy talk, that breathtaking sensation, the perfect timing of cumming just as he said it… Alphys moaned, pushing herself back hard on to his dick, his hot cum flooding her and making her his…
Her heart was pounding and mind racing as she did it. His? Really? This was pathetic even for her. This little boy, this student of hers, claimed her and made her… his? She had to admit, every time she thought that word, her heart leaped. The sheer wrongness of it all made it hotter. Maybe… she’d put her foot down and end this… eventually. But for now, his huge dick deep in her womb, his cum flooding her womb, for now… she’d let him think that… right, let him, she tried convincing herself.
She was a shuddering mess on her chair, every pulse of his cock sending shivers through her body long after he’d finished cumming or even moving. Just feeling him inside, his hips against her ass, felt like heaven. “K-Kris…” she managed to breathe, lifting her head with some difficulty and turning to look at him. Then her eyes focused, and a different expression came over her face.
“… C-class starts in 15 minutes,” she said, an edge of panic in her voice now. Oh god, time really did fly when you’re having your brains fucked out by a human. “W-we need- just pull out, quickly! Noelle normally comes early, she might be here any minute!”
Kris looks down at Alphys with a shaky breath, his knees buckling underneath him as his climax subsides. Has her behind always been this big and plush? With that thought in mind, he leans into her, pressing his body flush up against hers as he slowly drags his tongue along the nervous nerd’s neck. He even gives the spot a love bite for good measure, the force of his bite showing that he’s not afraid to get a little rougher with her.
When she turns to look at him, he meets her gaze, no longer her subordinate student but rather her superior. Hearing his name coming from her mouth is enough to make his cock throb inside of her once more.
“Hm? Oh, ugh, Noelle... Why does she have to be such a good student...” He mumbles, starting to pull out, his cum-covered shaft sliding out of her slowly and dripping onto the floor. Then, a lightbulb moment. His annoyed sneer turns to a sinister grin once more, and his hold on her hips becomes even stronger than before.
“Then you’re going to have to make me cum again pretty quickly, aren’t you~?” He pushes her head up against the chalkboard and holds her head there with a vicelike grip. His other hand pushes her lower half further down, jutting her ass out just a bit more before he rams back into her, a spurt of the seed that he shot into her previously pushed out onto the floor below. “That was way too quick, you didn’t think it’d be that easy, did you~?”
