One day, when the sun was shining brightly, I had returned to this countryside. In the past, I couldn't stand the stress of working in the city and came to escape, so I was vacant.But...it's different this time. I came here to fulfill my promise with Fuuka-chan, whom I met at this place. "Oh my brother... I'm sorry I called you even though you're busy with work." "It's okay. I was looking forward to spending time here too! And I've made a 'promise'. I'll definitely go to the school festival." "Hehe... thank you, brother." Yes- I've been invited to Fuuka-chan's school cultural festival this time and got here. "I've taken a week off, so let's make lots of memories for the school festival and other places." "Yes! Thank you!" This is how the third summer vacation for me, a low-ranking office worker, has begun -- Let's enjoy a naughty date with Fuuka-chan, who has become her girlfriend! Enjoy this naughty summer vacation with Fuuka, a busty country girl who has become even more sexy. This work is a sequel to "A sexy summer vacation with a busty country girl Fuuka" and "A sexy summer vacation with a busty country girl Fuuka 2 - Urban Edition."It's fun even if you haven't read the previous work.
