Raise is embarrassed of her curved futanari dick, but her otaku ways send her on a quest to a futanari-only "nap salon," where other futa girls get an eyeful of that curve. Raise is so ashamed, but the other futas think her dick seems delicious.
This story takes place in parallel to
Joint Futanari Practice 5 and after
Futanari Medical Socket, featuring the same protagonist.
I love the setting (all of Futaba Yodomu's books are interconnected), and the girls are gorgeous. Strongly recommended, and if you like it, click her name above and pick up some of her other books, they're all great!
