Their lips met. After a moment of kissing, Keine extended her tongue and licked Kars's lips. Kars quickly responded, and their tongues intertwined.
"He's so skilled… Kars is even better than me at this." Keine felt Kars's proficiency in this matter, wondering how many times he had done this with Cirno and the others to achieve such technique.
"Because I've been having sex with everyone almost every day recently, I'm already very skilled at this." Kars told her about his recent activities. Hearing this, Keine felt it was within expectations and wasn't too surprised, though she assumed Kars only did these things with Cirno and the others.
While they were kissing, Kars's hands had instinctively fondled Keine's breasts. The softness of her breasts never got old, no matter how many times he touched them, and this pleasure made Kars a little impatient.
"Teacher Keine, can you do it? Can you give me a blowjob?" Keine saw Kars pull out his cock, and when she saw his firm and strong erection, the turmoil inside her heart intensified.
"The order is wrong… It should be studying first, and then doing this. But my body…" While Keine was thinking, her hand was already gripping Kars's cock, slowly stroking it.
"But if I don't take care of this, Kars won't be able to study properly. So, it's fine to help him first." Realizing that things couldn't be stopped, Keine made a new decision to take care of Kars's physiological needs first before continuing with their studies.
She then squatted down and took Kars's cock into her mouth, sucking and licking it. The male scent made Keine feel her body getting excited.
"Teacher Keine's mouth sucks so intensely…" Kars felt the power of Keine's mouth, which seemed intent on sucking out all his semen, and he couldn't help but thrust his hips in pleasure.
"For you to resume studying quickly, I must work hard. I will calm your cock down." While Keine spoke, the tongue in her mouth sped up, licking his cock and further increasing Kars's pleasure. At this moment, Kars grabbed the two horns on Keine's head. This move puzzled Keine, but the next second, Kars suddenly pulled, making Keine swallow his entire cock.
"Mmm! Mmm! Kars… you shouldn't treat your teacher so roughly… be a little gentler… this… Mmm! I'll be uncomfortable… this is the time to…" Keine began to instruct Kars on techniques in this area. Such purely self-serving actions were not commendable.
Kars listened to Keine's words and began to make some changes. Although he was still holding onto the horns on her head, Keine felt much better. After the thick semen shot into Keine's mouth, her eyes went hazy. She tightly wrapped her arms around Kars's waist, letting his cock continue to ejaculate in her mouth until he finished before letting Kars go.
Savoring the taste of the semen, Keine felt her heart still craving the thick liquid.
"…Alright, Kars, let's study properly now." However, her responsibility as a teacher allowed her to resist the temptation. She sat next to Kars, preparing to continue the tutoring.
"But Teacher Keine, I still want to do it again." Kars hugged Keine's body, his hands fondling her full and tempting breasts and body. This behavior made it difficult for Keine to suppress her desire.
"But then your studies will fall behind. If you finish the tutoring content for today, I can continue to give you sexual gratification as a reward."
"Then let's do it together. I'll listen to your lecture while we have sex."
"That won't work, will it? You won't be able to concentrate on your studies, especially since you're already weak in this subject. If you're distracted now…"
"I can do it! If I can't, I won't do this again!" Faced with Kars's serious guarantee, Keine couldn't help but agree.
"This is truly absurd…" Keine picked up the textbook with one hand and lifted her skirt with the other, preparing to sit on Kars's lap. The thought of having sex with her student while studying was truly unbelievable.
After a little preparation, Keine sat down, and Kars's cock easily thrust into her pussy.
"Mmm, mmm~ I'm… completely filled… Is a cock this big okay for Cirno and the others' pussies… But this isn't the time to think about that. Kars, you must listen carefully to my lecture, or I won't do this with you again."
"Yes! I understand." Kars said, gripping Keine's buttocks with both hands and making her move.
"Mmm, aaah~ Then… what we are going to talk about today is… mmm~" While moaning and enjoying the pleasure, Keine began to lecture. The mix of her seductive moans and the course content was a test not only for the listener but also for the lecturer. Maintaining rationality to speak the content of the textbook and explain it was a significant challenge for Keine.
Every thrust of his cock intensified Keine's pleasure, making her want to drop the book and fully dedicate herself to having sex with Kars.
Even more surprising to Keine was that Kars was actually listening to her lecture properly. Unlike before, when he would get a headache and not understand, this time Kars remembered everything she said and answered her questions well. This completely different situation made Keine find it unbelievable.
"Could it be that teaching Kars this way significantly enhances his learning ability?" Keine could only come up with this explanation. She looked down at Kars, who was sucking her nipple. He seemed completely immersed in it, yet he was listening to everything she said without missing a word. Regardless, this was a situation Keine was happy to see.
"Mmm, aaah~ Alright, today's tutoring content is finished, Kars. Now, it's time for your reward from your teacher." After the content was completely covered, Keine casually tossed the textbook onto the desk. Her hands wrapped around Kars's shoulders. With no need to restrain her inner desires anymore, Keine's movements became wilder.
"Aah, aaah~ My pussy… my pussy feels so good being fucked by my student's cock! Hurry… hurry up and cum your semen! This is the payment I deserve, Kars!"
"I know! I'll reward you well, Teacher!" Kars hugged Keine's body tightly and began to thrust with full force. A stronger wave of pleasure washed over Keine, turning her expression into an orgasm-face. After the final thrust, his cock fully penetrated her uterus, and semen began to relentlessly shoot inside, making Keine let out a satisfied moan.
"So… so thick, so much volume… Kars, I'm very satisfied and proud to have a student like you."
"Me too, Teacher Keine, and I want to continue to serve you even better."
"You can. Your teacher loves a good student who knows how to repay favors." Keine kissed Kars's lips, and then the cock in her pussy started to move again.
