The delinquent girl Luwin was taking a humiliating pose.
Completely naked, it was a posture of lowering her head and sticking her ass out.
In that posture, the instrument was pressed against her anus, and she tightened her anal with a kyu.
While looking down at such Luwin's ass, Rigel declared in a flat tone.
"From now on I will begin the magic power examination. I will insert this instrument into your anus from now on."
"I-I got it!! Just do it already!!"
Luwin said as if spitting it out.
Looking at that reaction, Rigel grinned.
"Hmph… You're quite spirited. But it remains to be seen how long that attitude will last."
Saying that, Rigel slowly inserted the magic power examination instrument into Luwin's anus.
"Hyaaaaaah!?"
(W-what is this!?)
At the foreign sensation transmitted from her anus, Luwin's eyes widened.
Rigel said transactionally in a flat tone.
"The instrument is entering inside you."
"Kh… Uuu…!"
(It's coming in…!)
Luwin gritted her teeth and endured.
