Haikyuu!! -Lovemaking Techniques Learned from BL Manga (Doujinshi)

Our story begins with our Karasuno first years walking home together. Someone notices that Yachi is carrying a very heavy bag. She gets flustered about it and tries to divert their attention, but then the bag rips open, spilling its precious contents on the floor for all to see! Oh, what embarrassing things was she carrying?! The other boys are VERY interested... especially Hinata!
