'As always, my brother's cum is the best❤️'
Liana thought, licking the remnants of cum off her lips with her tongue with relish.
"Thanks for the treat, brother."
The sight of the panting girl in front of him, devouring his cum like the world's most delicious dessert, made Rain's cock even harder than before.
"I still feel empty in some places, I hope you can help me with that~"
With those words, she teasingly ran her hand over her pussy.
"Anything for my favorite sister."
Rain showed a loving smile and touched her hips. But before he did anything else, the voice of the system sounded in his head.
[Extra Quest]
[Fuck your sister until she passes out while another woman peeks at you.]
[Reward: A-rank weapon of your choice]
[Penalty for Failure: ---]
[Time Limit: ---]
After reading that, Rain immediately turned his gaze to the door connecting the office to the corridor. Since there were no windows, it was the only place from which someone could look in.
Indeed, as he concentrated, he felt a faint presence behind the door.
'Interesting...'
He had some guesses as to who this woman might be, but he didn't give it too much thought. After all, a quest is a quest.
'Since she's already spotted us... I'll make sure she never forgets it.'
At that moment, Rain felt a tug on his sleeve. Liana, with heavy breathing and clouded eyes with tears in the corners, looked up at him.
"Please stop torturing me and put it in."
She pleaded when her insides were already burning with eagerness. Her love juices dripped freely onto the desk as her clit twitched with anticipation.
"How dirty, you've already flooded the teacher's desk. What would your sister think if she saw you in this state?"
"I don't care, just put it in."
Liana replied, sliding two fingers apart her wet folds, exposing her pussy.
"That's an excellent answer."
Leaning the swollen tip of his hard cock against her soft pink pussy, he quickly pushed it inside.
"Hnnhhhaaaa~!"
Before her moan had even fully escaped her mouth, he repeated the motion with even more passion.
"Ahhhhhhhh❤️"
When she came to her senses a few minutes later, Rain asked her, keeping his insightful gaze on her.
"What did you talk to Ael about?"
Remembering how his sister had stolen the elven beauty away in a hurry, he really wanted to know the reason for her behavior.
At his question, Liana only remained silent and averted her gaze.
However, Rain didn't feel annoyed by this and only asked playfully.
"You don't want to tell your brother about this?"
One of his fingers slipped into her moist entrance, teasing her, causing a sweet shiver to spread through her body.
"If you really don't want to say it, I won't force you."
Another of his fingers plunged into her pussy, making more juices leak out of it.
"Nhhaaaaa❤️~"
Her neck, her collarbones, her nipples, he paid close attention to all her weak spots as his fingers played in her pussy, extracting a beautiful melody of muffled moans from her mouth.
"Mhaaaa❤️... haaaa❤️"
Her fragile mask of confidence gradually began to give the first cracks and soon, unable to withstand such pressure, Liana replied.
"I really just wanted to talk to her..."
Moving her pure violet eyes over to him, she continued.
"You're the one who wanted me to treat her better, that's why I wanted to get to know her a little closer and see if she was worthy."
Not expecting such an answer, Rain was genuinely surprised, but after a couple seconds he asked.
"And what conclusion did you come to?"
"...I haven't decided yet."
Her crumpled answer brought a smile to Rain's face.
'If it's not a firm refusal, then she's about to accept her.'
Bringing his lips to his still confused sister's lips, he kissed her deeply with his tongue.
*Chuuup❤️*
As they did so, the sound of footsteps, which someone was clearly not trying to hide, echoed in their ears. After another second, they both realized that the footsteps were approaching this room.
After looking into each other's eyes and exchanging silent agreement, they jumped up abruptly from their places, trying to cover up everything that had happened as quickly as possible.
Liana hastily began buttoning her shirt and adjusting her skirt while Rain cleaned up the mess on the table.
But before they could fully do so, there was a click of the doorknob and the door swung open, whereupon the person they least expected to be here entered.
