In answer to your question, the hentai is “Rin x Sen + Ran: Sem Cross Mix.” It is a crossover between the two original series: “Rin x Sen” (Japanese title: “Rin x Sen - Hakudaku Onna Kyoushi to Yaroudomo”) and “Ran - Sem” (Japanese title: “Ran - Sem: Hakudaku Delmo Tsuma no Miira Tori). To the best of my knowledge, there are two episodes in each series.
