Holding his cock in her hand, Amelia's gaze was fixed on it as she unconsciously asked.
"What size was it originally?"
Rain didn't answer her question and instead assessed her condition.
[Lust 39↑]
[Lust 40↑]
[Lust 41↑]
Rain didn't know the exact reasons why her lust level was rising so quickly, but he realized this was his chance.
"I'm not sure what it was originally, but I do know that it can get even bigger if you help a little."
Her cheeks quickly flushed to a deep red color from embarrassment. Amelia wasn't so naive that she didn't realize what he was talking about.
She looked up at his slight smile, accentuated by the glint in his red eyes that seemed to whisper devilishly to her that she should go a little further.
Her heartbeat echoed in her ears and forbidden desires rose from inside as one question swirled in her mind.
'Should I go that far?'
She soon found the answer to that question.
"We can't... I'm the teacher and you're the student. The rules of the academy forbid such a relationship."
In response to her words, Rain only shrugged his shoulders.
"On my way to the academy today, I noticed some small rocks on the side of the road..."
"...?"
"Since you started talking about things that don't matter, I decided to do the same."
Her eyes widened at his statement and she stared at him silently, unable to utter a word.
It wasn't until half a minute later that she moved. Though she said nothing, her actions spoke for themselves.
'I'll just test its limits.'
Amelia tucked her hair behind her ear and bent her head over his cock. Then she dripped her saliva copiously on it and smeared it all over the length of his cock.
Next, her hand gripped his cock tightly and Rain felt a familiar sensation of arousal run through him.
'She actually did it.'
Rain thought as Amelia's hand began to move smoothly along his rod.
The sound of her breathing filled the room as she stroked his cock, feeling the heat emanating from it.
Rain stopped playing with her nipple and slid his cock between her breasts, which, regardless of their owner's will, quickly engulfed him. They were large enough for him to slide his cock horizontally into them.
Amelia squeezed the ends of her shirt insistently, apparently having made up her mind.
"Try to cum as fast as you can."
Her hands squeezed her breasts, greatly increasing the pleasurable pressure on his cock.
While Rain was indulging in this pleasure, there was a knock at the door. Before he could get angry that someone had interrupted him, a knock was followed by a familiar voice he hadn't heard in a long time.
"Sister, are you here?"
Amelia flinched slightly upon hearing this and even stopped her actions.
But despite her reaction, Rain only smiled evilly and, not planning to stop here, whispered quietly to her.
"Just be quiet and he'll go away on his own."
With those words, Rain resumed his movements and concentrated on the pleasure he was getting from the woman in front of him.
However, Cale didn't leave even after a couple minutes of silence, for he felt that his sister was here, and his premonitions rarely deceived him. So he trusted them and continued.
"Are you still angry with me?"
Cale asked, genuinely expecting an answer from his older sister, whose breasts were squeezing everything out of Rain's cock right now behind closed doors.
"I'm sorry I yelled at you last time... I'm just not myself lately."
Once more his voice with a tinge of guilt rang out, muffled by the thick door.
Noticing Amelia's gaze shifting more and more toward the door, Rain felt a little irritated, causing him to immediately grab her breasts.
"Ahmmmmm~"
He squeezed her erect nipple and, without releasing it, whispered sternly.
"Don't get distracted and just ignore him."
This action brought her attention back to him, and her breasts squeezed his cock again from all sides, almost causing him to moan in pleasure.
Her posture as she knelt in front of him in a strict suit with black stockings, not letting go of his cock, increased his arousal to the extreme as he plunged his cock into her breasts with eagerness.
'The hero's sister... it's really a different feeling.'
But his thoughts were soon interrupted by the sound of the door opening.
"I will take your silence as a sign that you have forgiven me. Then I enter, sister."
