Manga Tube - Soshite Watashi wa Ojisan ni 1

Nanami and Sakura are inseparable buddies. Both Nanami and Sakura are strong-willed and reliable, but Sakura has a gigantic bust that is out of proportion to her diminutive frame. They are buddies from school, but they also have a familial tie. The father of Sakura's friend Nanami sees her as another of his daughters when they go for a drive together on her days off. This gives Nanami hope that he will marry Kanako, Nanami's mother. The confidence she has in him is evident. That is, unless... Please tell me... A primordial demon who has no sense of rationality is rummaging through Sakura's room in front of her, instead of the fun and friendly uncle she is accustomed to seeing every single day. You're a nasty person.
