Rigel was performing cunnilingus on Nina.
This act served both to humiliate her and as a tactical measure.
As a lightning mage, Nina could unleash a powerful thunderbolt at the cost of self-sacrifice.
To prevent her from completing the chant, Rigel was attacking her with his tongue, making it impossible for her to concentrate.
Furthermore, when a woman climaxes, she releases magical power.
Rigel's plan was that if he made Nina cum repeatedly with his cunnilingus, she would eventually become unable to cast any magic.
As time passed, his paralysis would also wear off.
That would be the moment when Nina lost her virginity and Rigel's victory would be assured.
(Still… this girl has a pretty nice pussy. I'm looking forward to putting it in.)
Thinking this, Rigel extended his tongue.
By the way, Nina was still fully clothed.
As a mage, she wore a robe, and only the area around her crotch had been lifted up by Rigel.
"Hii!?"
