[Synopsis]

''I'm sorry, Kuroya... but just once for you... just once...''
Our heroine, Misakura Haruka, has her childhood friend and beloved lover, Akise Kuroya, suddenly taken away by mysterious tentacles.
The only way to save him is to transform into a "magical girl" and the way to do so is... "by having sex with a man and filling her uterus with semen".
Though confused, Haruka decides to become a magical girl in order to save her precious lover and then... she passionately touches skin with a man who is not her lover...

Can't complain here.

This NTR goes straight to the point.
The little bastard magical pet blackmails the heroine into NTR by abducting her BF, let's be real the coincidence is way to convenient so it has to be the evil pet contractor.
Then the PE teachers he's just the meat dildo of the story but takes advantage of it while the poor BF is just forced to watch.
It reminds me of another story with magical girl NTR.
