"It's already so swollen. We must treat it properly." Eirin Yagokoro looked at Kars's vigorous cock, caressing it with her hand while licking it with her tongue.
"So, Kars, what kind of treatment would you like? Mouth? Hand? Or my breasts?"
"I want the Doctor's breasts!"
"Is that so? You really do like breasts." Eirin Yagokoro quickly unbuttoned her top and used her breasts to sandwich his cock, using both hands to perform an a-cup blowjob. At the same time, she opened her mouth and let her saliva drip onto the cock, making the friction between the cock and her breasts even smoother and more comfortable.
"The Doctor's nipples are so beautiful." Kars reached out his finger and poked Eirin Yagokoro's nipple, sinking his entire finger into it. This action made Eirin Yagokoro moan with arousal. Then, Kars started pinching the nipple with his fingers, gently tugging it, further intensifying her sensation.
"N-no, I can't… I'm going to cum… Aah, aah~" As a high-pitched moan erupted from Eirin Yagokoro's mouth, a puddle appeared on the floor, and drops of fluid occasionally fell from between Eirin Yagokoro's legs.
"I can't hold back anymore; I want this strong cock thrusting into my pussy." Eirin Yagokoro lifted her skirt, turned around, and presented her bare, peachy buttocks to Kars, saying, "Do whatever you like, Kars."
Hearing this, Kars looked at Eirin Yagokoro, who was standing with her hips raised and her back to him, and he leaned his whole body onto her back. His eager cock gently rubbed against her pussy.
"Hurry… hurry up and insert it. Don't tease me like this." Eirin Yagokoro reached down and gently guided the cock into her pussy. Kars pushed, and the cock smoothly entered, causing Eirin Yagokoro to let out a satisfied moan.
As Kars slowly began to move, his cock started thrusting inside her love-juice-soaked pussy. With every thrust, the sound of the cock passing through the tight vagina and hitting the end could be heard. Due to the internal wetness, the wet sound of the thrusting was exceptionally clear.
"Eee wuwu~ So… so amazing… I completely love the feeling of the big cock going in and out of my pussy…" Eirin Yagokoro, who was somewhat unstable, slowly spread her legs wider. However, not wanting to interrupt the copulation that she was so addicted to, Eirin Yagokoro bent down, supporting herself with her hands on the ground, maintaining the posture of spread legs and high, raised hips. This posture also allowed the cock to penetrate deeper into her pussy, entering her womb, making her voice and expression even more alluring and sexual.
Kars looked at Eirin Yagokoro's sexual climax expression and thrust his hips even harder, increasing the speed of the cock's in-and-out motion.
"At first, I thought the Doctor was a bit scary, but now I see I was wrong. The Doctor is a very kind, gentle person, and her pussy is wonderful. I truly like the Doctor, so I will make the Doctor's pussy feel even more comfortable with my cock. This is my apology to you, Doctor."
"Aah, aah~ Being able to think of such an apology… Kars is a wonderful boy. Continue… continue to use my pussy hard."
She was completely captivated… completely immersed. All that was left in her mind was the thought of nonstop sex with this boy, being played with by his strong, young, big cock. So happy. So this is what it feels like to be a woman, how blissful. I can't leave this cock; I can't imagine what I would do without it in the future…
"I'm going to cum…"
"Cum… just cum it all in. Let my womb and eggs be completely violated by your semen!" At Eirin Yagokoro's fervent plea, the hot semen shot into her womb, quickly filling the entire space inside. The excess semen soon flowed out of her pussy, dripping onto the floor.
"Aah, aah~ I'm completely full of semen…" Eirin Yagokoro's face was marked by a look of satisfied climax. Nothing in her past had ever made her feel this happy.
Afterward, Eirin Yagokoro sat on the chair, holding Kars, who was sucking on her breasts, watching him work his hips hard, thrusting his cock into her pussy.
"Kars, you must come to me every day from now on. Sexual physiological treatment cannot be skipped, even once."
"Mmm, I'll remember to come to the Doctor for treatment."
"Such a good boy, listening to the Doctor. In that case, I will also give you more good-boy rewards." Eirin Yagokoro finished speaking, and Kars felt his cock tighten, gripped by her pussy. As it slowly began to contract, the pleasure from the friction between his cock and the internal folds of her vaginal walls made Kars's body feel somewhat weak.
"The Doctor's pussy… is amazing…"
"Come on… keep up the good work. It's not time for the treatment to end yet."
As the sex continued, when Reisen finally found Kars, he was already in Eirin Yagokoro's room. Watching Eirin Yagokoro sitting on Kars and moving her body up and down relentlessly, Reisen could feel an even stronger desire radiating from her than when she was in heat.
"As expected, the accumulation of years of repression, once it bursts out, is truly terrifying." Reisen realized that this situation clearly wouldn't end anytime soon, so she could only leave. After all, she didn't have the guts to go in and fight with her Master for the cock. She didn't even need to imagine the consequences of that.
