A succubus's prank of draining stamina, visible only to me (the summoner); a school life where I'm forced to ejaculate in front of everyone; Kurumi Sakura MIAB-558

[Everyone...can't you see the succubus here!?] [During class, next to her...12 shameful ejaculations!] Ahh, even though I'm shy in front of my friends...I still can't help but show my penis and shake my body! ...So cute...so horny...! I don't care if I drop out of school, as long as I can ejaculate on this girl!! ...One day. On my boring usual way to school, I picked up a suspicious book on the roadside with something that looked like a spell written on it. I casually read it aloud...and it actually summoned a succubus! This thing follows me around school, always aiming at my semen and touching my penis! Don't do this in front of everyone! You'll get caught! "It's okay, only you can see me!" This is...a succubus version of something like the Death Note has descended upon me...! Because I can't see her, I can play pranks on my teachers and friends as I please, and even ejaculate in class...! But is it because of the magic? I can't resist, my rationality collapses, and I suffer a defeated orgasm! In everyone's eyes, I'm a super pervert who repeatedly twists his waist and ejaculates. Of course, the teachers would be furious. I might get expelled. Even my relatives and friends have given up on me... But I have a succubus. Today, she can make me ejaculate comfortably too...
