【Yuna】My little sister! The first time I went with my brother, he confessed to me on a trip to a hot spring. (6)

The shy little sister suddenly comes on to me boldly and says she’ll make my brother feel even better…?

This is the first time I’ve ever seen this movie.
The story takes place in a small town in the middle of nowhere.
When the older brother peeks at Risa’s changing clothes as an act of watching her grow up, he gets excited to see her naked!

They decide to take a bath because they can’t calm down and eat.
Then Risa shows up naked in the bath and says, “It’s my fault, isn’t it?" and takes her brother’s enlarged penis in her mouth…!

It feels so good, my lower body is melting!
