Xavier sat in the chair, legs spread, holding his cock straight up.
Nyxara turned around, presenting her ass to him. One of his hands guided her hips down. She sank slowly onto him, taking the thick head inside first.
Mmm... ahh...
Soft moans spilled from her lips; with every inch the sounds grew louder and deeper
Aaah... unngh...
until she had swallowed his entire length and her soft, plump ass rested fully on his lap. Her squishy flesh spilled outward around the base of his cock.
Ohhh...
Her insides were tight. Every ridge of her pussy gripped his cock.
Staring at that obscene round ass, Xavier could not restrain himself. His hand came down in a hard slap. The sharp smack echoed through the lab and left an imprint of his hand on her delicate skin.
Nnngh—!
Nyxara moaned in pain and pleasure together. She turned her head to look at him. "Why did you do that?"
"Your lewd ass was asking for it," he answered. He gripped her narrow waist and urged her to move.
Nyxara lifted herself and drove back down. She began to ride him in earnest, each descent burying him to the root.
Mmph... aaah...
Her folded pencil skirt loosened at the waist; the buttons of her tight shirt popped one after another under the violent sway of her heavy breasts.
Plap Plap Plap
Ohh... nnnh...
Her ass cheeks smacked against his thighs while the head of his cock kissed the deepest part of her cunt on every stroke.
Xavier’s hands climbed from her waist to her chest. He yanked the ruined shirt open and freed her tits so they could bounce freely. Then he slid lower in the chair, pulled her shoulders back against his chest, and took control. Holding her by the hips, he lifted her just enough to thrust upward, pistoning his dick into her with steadily increasing force.
Aahhh... fuck—...
Her love juices spilled freely, slicking every stroke.
Xavier had already been close from the unfinished blowjob; the new pace pushed him toward the edge. Nyxara had begged for a creampie, and he intended to give it to her. He drove deep one final time, the head of his cock pressing against the entrance to her womb, and unloaded. Thick, hot gushes of cum flooded her in long pulses that lasted far longer than usual—the earlier teasing had filled his balls to bursting.
Ahhh—!
The moment the first jet of heat struck her insides, Nyxara’s body twitched. An electric rush raced from her stuffed pussy straight to her brain.
"Yes—yes! Give me your seed—impregnate me!" she cried, grinding down to take every drop.
Ohhh—... yes—yes—
A student impregnating a professor... that might just become the next legend of the Imperial Academy, Xavier thought.
Even after the last spurt he stayed buried inside her, savoring the fluttering aftershocks of her walls. Nyxara melted against him, relaxed and warm, his still-hard cock keeping her full.
Mmm...
He turned her face and claimed her mouth in a slow, possessive kiss. "You’re my woman now."
Nyxara giggled against his lips, her green eyes bright with happiness. "Of course I am. You can come inside me whenever you want. The more, the better—we’ll have so many babies."
Xavier had no reservations about fathering children with her. His other girls were still students; he had no intention of impregnating them yet. Nyxara, however, was a mature, fertile MILF who had begged for it, so he didn’t hold back.
After they cleaned up and dressed, Xavier remembered the question he needed to ask.
"Professor, do you know anything about elemental sword summoning?"
"From what I know, it is one of the advanced conjuring techniques," Nyxara answered. "You need at least third-level mana control to attempt it. Given the purity of the mana you imbued earlier, and the quality of the extracts you handled, I would place you around the third level already."
She continued, "You will also need affinity with the element you wish to conjure. I can help you test that."
Xavier followed her into the adjoining office. She opened a drawer that contained several rings with different colored crystals and a small orb containing a tiny void.
"Imbue your mana into this. It will reveal your elemental affinity." Nyxara took out the orb.
He did as instructed. The void inside the orb flared with pure white light.
"Interesting," Nyxara murmured. "It appears you possess affinity with every element. Conjuring any type of elemental sword should be possible for you."
"But how do I actually conjure it?"
"You already have the affinity and the necessary mana control. What you still need is a tether—something to anchor you to this world while you travel into the sword realm. Unfortunately I cannot help with that myself, but I know someone who might be able to help."
Unlike summoning familiar beasts, elemental sword conjuring required the caster to enter the sword realm and perform a binding ceremony there.
Nyxara glanced at the clock. "Speaking of mana control—don’t you have the lecture today?"
Mana control was the second compulsory subject set by the Imperial Academy, and this morning was its first lecture.
Xavier checked the time and realized just how long he had spent fucking her. He needed to leave immediately if he wanted to arrive on time.
"Professor, I need to summon an elemental sword. Please talk to that person you know about it," he said as he headed for the door. Nyxara had already offered him quite a lot just for his help in synthesizing the potion; now that he had made her his woman, he didn’t hesitate in asking favors.
He reached the classroom just as it was filling. Melli and Elena sat together; both looked up when he entered. Xavier greeted them good morning and took the seat beside Melli. Elena quickly rose and shifted to his other side, sandwiching him between them.
To his left, Elena’s huge breasts pressed against his arm. To his right, Melli’s thick thighs brushed his. Both girls sat close enough that their bodies continually nudged and claimed his attention.
Before Xavier could decide how to react, the mana-control professor strode through the door and took her place at the podium.
Xavier’s mind went blank.
The way she was dressed was outrageous.
