Tropical Island Maniacs: My Host Family is so Lewd! 7

Kei makes the best of his remaining days as a transfer student in the tropical islands of southern Japan by having some happy "farewell sex" with Tamaki and a, now, pregnant Tsuzumi. But not everything goes smoothly, as Akari seemingly snaps at Kei for every little thing that he does. But when the reality of him leaving dawns upon her, she finally rids herself of all pretenses and expresses how she truly feels towards him.
