Spends a LOT of time and panels establishing how thoroughly the Dad fucks her but the switch to him finally fucking his so-called "tutor" is abrupt, awkward, and in the end pointless. His clumsy, virginal assertions after what she's been doing with his Dad won't turn her head unless she is just playing games to make the Dad "jealous" and fuck her HARDER! This was essentially a cuckold scenario with the cuck being the unknowing, virgin foil for YEARS! If there is a sequel let him redeem himself by conquering her differently, plundering her anally in her only virginal orifice!
So, is it netorare because his father fucked her behind his back? Or because he stole her (or at the very least tried to) from his father after learning what she really was like?
Well, the tag is right there.
That being said, it's another one where the NTR feel isn't as prominent? Simply because it's more of a one sided crush on his end.
Interesting ending though. I have to give him props for rather than breaking down crying or being down in the dumps, he decided to make a move and claim her as his girlfriend despite everything he witnessed.
Good job. Now let's see if he can keep her...
