Soshite Watashi wa Ojisan ni......

Nanami and Sakura are best friends. Nanami is the elder sister who is strong-willed and dependable, while Sakura is the reserved, but lovely little girl, who has a mega bust that is disproportionate for her petite body. They are friends from school, but they also have a connection through their families. On her days off, Nanami goes for a drive with Sakura’s father, Shouhei, and he treats her like another daughter. This makes Nanami wish that he would marry to her mother, Kanako. That’s how much she trusts him. That is until… “What are you doing…?” In front of her isn’t the fun and nice uncle that she’s used to everyday, but a primal fiend who has no sense of logic as he rummages through Sakura’s room. “You’re disgusting…”

Eroge! H mo Game mo Kaihatsu Zanmai

Based on the erotic game by Clock Up team Anise. Mochizuki Tomoya is a guy that lives on his own with only a day job at a convenience store keeping him afloat. While he really likes eroge, he can't draw, isn't much of a writer or composer, and doesn't know much about business. Still, his dream is to get a job at an eroge studio in hopes of creating what he loves, eroge. Tomoya's luck takes a turn for the better when he sees a help wanted ad for the local studio Flower, and after a meeting with the company president (who to his surprise looks like an elementary school kid), manages to get a job as administrator of the company's website. Tomoya's glee at being part of the eroge industry is short-lived, as he soon learns that Flower is on the chopping block due to their first title being a massive failure. After playing through Flower's first title, Tomoya realizes that his co-workers don't know anything about eroge, lacking the insight and understanding needed to make a good game. After some nudging from the president of Flower's parent company and some soul searching of his own, our protagonist takes it upon himself to save Flower by teaching the four girls on staff the ins and outs of what makes an eroge good. The story thus focuses on Tomoya's role as a psuedo-consultant while getting to know the four heroines of the story as the player is given an interesting look at the world of eroge development.
