We take Iroha, a modern girl who does Iroha from masturbation to watching porn to eating, on a sex trip to a southern island. She is a sex athlete who is greedy and masturbates every day with her phone in hand, and has a masochistic temperament who wants to be bullied and creampied. No matter how hard the play is, this athletic M-girl never gives up, and in the end, she finishes with a creampie! A raw tropical exchange with a modern volunteer soldier with beautiful legs and a slender figure!
