Ah, a lovely succubus (cosplay) release!
I don't really think there's a problem with using sex as a stress relief? I mean, as long as the partner is said boyfriend.
Great ending though. Well hey, at least she is asking him to go out with her rather than become like, a sex friend or 'stress relief partner' or something.
I was kinda hoping we'd get to see her mother's reaction at the end though, seeing them getting along so well.
To borrow words from a long-running and world-famous children's television program, (clears throat) this story by Enuhani-sensei was brought to us, by the letter "E", as in the words:
Excellent! Enticing!! Enthralling!!! Exhilarating!!!! Exciting!!!!! Erotic!!!!!! ... and most of all, ENTRAPMENT!!!!!!!
In The End, There Can Be Only One Conclusion IMHO; the same conclusion I reached regarding Sensei's second work on FAKKU: "DAYUM!"
