Fuuuuuu...!!! T_T When you realize that the other story was about the dads! One night, that's all they had? So sad! No wonder Yuuen's dad understood and accepted so easily.
In fairness, as smutty as this is, it turned out very uh, respectful of their ages as it is. Kudos to the teacher.
But damn, that kid's imagination is a formidable weapon! Can't wait till his body catches up to his libido and he finally gets to bang teacher-san! Heh
The heck! The dying old lady was his daughter! T_T
Also, they better have some hawt vampire sexy times in the future, ok? Ok!
