Junjou Decamelon - 2

In order for Seiya and Momoti to develop healthy relations, President Rose arranges them to work in the school library, but they continue to have exhibitionist sex there. Since her plan did not work, the rose punishes the Momot, forcing her to become a model for drawing among students. The erotic performance of the momot cannot but excite the rose, and it joins the group.
After the sexual incident with the model, the fetish was awakened by the anal sex. She begins to engage in anal masturbation in public places, trying not to find her. Once in the afternoon in the library, she is discovered by a classmate Inita and admits to her in her feelings. Rosa accepts the recognition of the Initu, and they have sex right there, not suspecting that Momota and Seyu were secretly watching them.
Then the students went on a school excursion on the coast. They planned to look at the stars together, but no one arrived. Having left alone, Seyu says the MOMOT that you can undress, to which she agrees and undresses naked. And Seiya understands that the feelings that he experiences for the mind has become even stronger.
