Kakushi Dere: vol.3
Kakushi Dere is a hentai that so far has two episodes and two stories each involving two people getting together. The first episode is about a high school girl named Nonoka who goes over to the house of her new male "acquaintance." There, she meets the boy's older guy named Ryutaro who is actually the protagonist of this episode rather than his guy. When his younger guy leaves for more than half an hour to go buy a movie to see with Nonoka, Ryutaro is left alone with this tsundere girl. Of course, being a hentai, things happen and Ryutaro's younger guy never gets to watch the movie he buys for Nonoka (poor guy). In fact, Nonoka was never involved with Ryutaro's younger guy and really didn't seem to care about him at all (just Ryutaro). The second episode is about Makoto and Misaki (who is about as tsundere as you can get). Misaki quiet has feelings for Makoto and one day is accidentally caught by him while masturbating in his room. Despite Misaki being an extreme tsundere, they finally both convey their feelings to each and have sex. This is a good hentai.
