This doujinshi is a spinoff from the officially released Jackal & Pomeranian series.
Akane Shimose is all fired up to give her grumpy senpai, Gen Inomata, the best date ever! Too bad everything that can go wrong, does. But if there's one thing these horn dogs excel at, it's raunchy romance—even if it means fogging up the windows of a parked car!
