[Everyone... can't you see the succubus here!?] [During class, next to my girlfriend... 12 embarrassing ejaculations!]
Oh, even though it's embarrassing in front of my friends... I can't stop shaking my hips with my dick completely exposed! ...Cute... Sexy...! I don't care if I get expelled or whatever, I just want to ejaculate into this girl!!

...One day.
On my usual boring walk to school, I picked up a suspicious book on the side of the road and found something that looked like a spell written in it.
I casually read it out loud and... I can't believe I summoned a succubus!
This thing follows me around school, always touching my dick in an attempt to get my sperm!

Stop doing that in front of everyone! I'll get caught!

"It's okay, you're the only one who can see me!"

Oh dear... a succubus version of that [Death Note] thing has come upon me...!
Just because he can't see, he plays pranks on his teacher and friends as he pleases, and milks them during class...!
But perhaps because of her magical powers, he is unable to resist, and his reason is broken as he cums in defeat!

Everyone can see him as a total pervert, shaking his hips and ejaculating repeatedly.
Of course, the teacher is furious. He might even be forced to quit.
Even his best friend has given up on him...

But I have a succubus. She will make me cum in pleasure again today...
