"So... so incredible... the feeling of the cock inside... is it really this good? My whole body loves it..."
Kasen couldn't help but grind her hips. She was addicted to the sensation of the cock thrusting within her. Her movements became more and more vigorous, and she failed to notice Kars slowly waking up.
"Hmm? This feels good... is someone doing something?"
Aroused by the pleasurable sensations on his cock, Kars gradually woke up. Opening his eyes, he saw Kasen bathed in the moonlight, her hips moving rhythmically as she ground herself against his cock.
Kars was fully awake now, and quite surprised to see Kasen so immersed in sexual pleasure. He decided it was time for a little conversation.
"How is it? My cock feels good, doesn't it?"
"Aah~ yes... it is... I've never felt so... EH!?"
Kasen realized what she had said and froze. Her face turned a fiery red as she realized Kars was awake and watching her. Intense shame washed over her. Just as she was about to try and explain, Kars thrust his hips up, driving his cock deeper into her pussy.
"If you like it, don't stop. Enjoy yourself. That way you'll understand the joy even better."
"Aah~ this... I can explain... mmm~ don't keep doing that..."
Kasen tried to stop him, but her body was too weak to resist. Kars pulled her into a kiss, his tongue forcing its way into her mouth and entangling with hers.
Reimu, sleeping nearby, suddenly turned over, making Kasen even more nervous. Her body tensed, causing her pussy to grip Kars's cock tightly, sending a surge of pleasure through him.
"Wuwu~ stop... Kars... Reimu will wake up..."
"So what if she wakes up? It doesn't matter. Or are you just embarrassed that you snuck around behind her back? Think you won't be able to face her again?"
"Wuwu..."
Kasen couldn't answer. Kars was right; if Reimu found out, she would never be able to face her again.
"In that case, tomorrow I'll tell Reimu I was the one who went after you. I'll say I couldn't resist while you were sleeping, and that you didn't blame me, but instead realized the joy of sex. What do you think?"
"Is that... really okay?"
"Of course. Reimu won't find it strange no matter what I do. So let's just enjoy ourselves."
Kars began to thrust more forcefully into Kasen's pussy. She soon returned to her previous state of bliss, her eyes glazed as she kissed Kars and moved her hips to accommodate his cock.
As she felt Kars's cock begin to throb, Kasen realized he was about to ejaculate.
"Mmm~ mmm~ can you... can you cum outside?"
"Of course... not! How can you say that at a time like this? I'm definitely going to ejaculate inside your pussy. I won't take no for an answer, or I'll tell Reimu you snuck into my bed at night."
"You... you're so mean... how can you be like this..."
"So, do you really want me to cum outside?"
As Kasen reached her own limit, her body didn't want him to stop.
"I... I want it..."
"Right? Here it comes~"
Kars gripped Kasen's buttocks firmly and pulled her down as his cock began to ejaculate deep within her.
The sensation of the semen filling her uterus sent tremors of excitement through Kasen. Her face was flushed with a dazed, blissful smile. Her pussy gripped the cock tightly, milkng every drop of semen from it.
"Now that you've experienced it, what do you have to say? Still want to lecture us?" Kars whispered in her ear.
"No... I won't... I love sex so much... I want to do this with you every day..."
"No problem. I'll show you even more of the joys of sex."
"Mmm~ please, Kars."
With a happy smile, Kasen kissed Kars again. Her pussy clung to his cock, unwilling to let it go.
The next day...
"So that's what happened!"
Kars had his arm around a blushing Kasen, massaging her breast while he gave a grinning explanation to Reimu.
"Tch. Typical of you."
Reimu didn't seem to care. She didn't find it strange at all. Seeing the Kasen who had been lecturing her yesterday now manually masturbating Kars, she wasn't surprised in the least.
Kasen breathed a sigh of relief that Reimu didn't suspect her, but she still felt a bit humiliated. Thinking back to her words yesterday, she felt Reimu's gaze was a bit piercing.
"Kasen, I'm going to cum. Use your mouth."
"I... I understand."
Kasen leaned down and took the cock into her mouth. Soon, the semen shot into her mouth, and her face showed a look of pure, unadulterated happiness.
