Kiss Hug Episode 2 , English
A guy who's been an introvert for his whole life doesn't have a lot of friends and spends most of his time alone. Two girls take a notice of him and keep him company all the time. When the girls learn that he is a virgin and hasn't even kissed a girl before, they decide to "his first" in all of those things. His first kiss, his first blowjob, his first creampie, and so on. They quickly make a game out of it and so his harem was created.
