Eroge! Sex and Gamedev S1:E4

Himeno Kisara Love, Has Begun Chapter

Mochizuki Tomoya, an otaku aficionado of eroges, is hired by the struggling eroge development company Flower, whose next production must turn a profit or else go bankrupt. He finds out that the employees of the company, Himeno Kisara, the chief artist, Fujiwara Momoka, the scenario writer, Kousaka Iori, the graphic designer, and Sunono Nene, the company president, are all virgins and have hardly any experience with eroges at all. The company office doesn't have functional air conditioning so during the summer everyone works wearing minimal clothing. One day, after everyone else has left the office, Tomoya looks over Kisara's artwork and finds that it is substandard and unrealistic, and so to improve its quality, he starts off performing actual sexual acts with her, so that she has reference for her artwork.

Sopping Wet!? Beautiful Girl Creators Chapter

Kisara's artwork has substantially improved as a result of Tomoya's providing her with true references for it, so this time Tomoya begins looking over Momoka's scenario writing, and finds that while there is plenty of romance in it, the amount of sexual content is insufficient for a game of the sort they are trying to make, and she seems to be suffering from writer's block. One day, after everyone else leaves, Momoka begins playing dominatrix to Tomoya's submissive, even though he objects that he isn't a masochist. The two eventually have intercourse, and halfway through their roles switch. This serves to break her writer's block. A few days later to help the team relax, Nene and Reina bring them all to the beach. While everyone else is playing, Iori takes Tomoya aside gives him a blowjob, intercourse, and finally urine play. A few days later, he comes to Kisara's house to help her with her doujin manga side project...

A Peach Coloured Sigh, Once Again? The Newest H-game Is Filled with Momoka!! Chapter

This episode goes back in time somewhat to cover Momoka's route. Tomoya is dissatisfied with Momoka's writing work although he initially has a hard time approaching her as she seems to have a general dislike for men. Eventually she approaches him and they confront each other, Tomoya saying that her contemptuous attitude towards men is causing her writing to suffer, while Momoka maintains that her attitude is justified. The two begin to attempt to prove each other wrong by performing sexual acts of increasing boldness, from simple blowjobs until finally they have full intercourse. This fails to make either accept the other's position until one night with Momoka alone at the office Tomoya pretends to be rapist who breaks into the house and rapes her. She believed he was an actual rapist despite Tomoya's very thin disguise, so Tomoya apologises to her just as she is about to cry. The next few days Momoka is very cold to everyone, especially to him, and Kisara confronts him about this...

After everyone else goes home, Tomoya stays behind, saying that he's the new guy and has to put in extra hours. Soon after, Nene returns to the office with a lot of beer, depressed from not being taken seriously at meetings because despite being 32 she still looks like a child. She asks Tomoya what she can to to look more mature. The next day, Flower has a booth at an otaku event to give away demo copies of the new game and market their old games and related merchandise. Nene, Kisara, and Tomoya are assigned to man the company booth while Iori and Momoka are promoting the latter's doujins also at the same event. In response to Nene's question about how to look more mature, Tomoya has put remote control vibrators into her vagina and anus, and turns them on and off as customers visit their booth. She manages to give away the last copies of the first batch of the trial version of their game just as Tomoya finally makes her orgasm...
