Not sure with the Sexual Pursuit story

After watching it, the story put a question mark over my head. I looked at the reviews and they don't match what I just watched. It's a two part hentai and they really don't match up much. The first part had Yuuji and his mother playing a dice game. Then the game had them do sexual thing to each other. At first they don't know why they could not stop themselves, but then enjoyed called each other lovers. Afterwords they walk in the living room and the sister didn't know anything about it.

Then in the second part it shows sister (Aoi) walking in just when they about to play the game. But shes' some kind ghost that can't do any thing, and just watches them have sex. She wakes up and it seems to be a dream, like it didn't happen. As the story goes on she keeps remembering about the dream and finds the dice game. She just picks up a card ask Yuuji about why did one of the cards from said masturbate on it. The card makes her start playing with her self in front of him. They had feeling for each other and had sex, and are lovers now.

So is it showing two different endings or what? Please answer this is bugging me.

lol Sexual Pursuit. This was so bad. I was confused too though. My theories are a) what you said with 2 possible endings or b) that board game is really messed up and maybe let the sister have a dream or hallucination or whatever of the mom and son banging (which possibly still did happen like in the first ep), which would lead the sister to being curious, finding the game, and letting it work its magic yadda yadda yadda.

How old is it? I can't remember if I have watched it or not.

Its honestly not as confusing as you think (and I don't let myself get confused by it).
Both episodes are parallel stories, the "branching" occurs after Yuji got the board game. What his sister saw as a dream on episode 2, was the result of the other parallel story which is episode 1, where Yuji showed the Board game to his mother first.

I think it was made in 2008?

I glad to know now it's just two different endings. It confused me because it really didn't make things clear on what happen in the end. Thanks for the help out! :)

ohhhh I remember that. Yeah I think I was also unsure at the time and had to rewatch some parts to understand it was two different endings.

Yeah, I always considered it to be two separate endings. Although I didn't think too hard about it to the point where it would confuse me.
