I dunno how long subs usually take on this site, but I thought this was really good, so I want to provide a rough guideline of what happened in case it wasn’t clear without subs. I don’t know if this is allowed, I read the FAQ but it was largely unrelated to commenting, so hopefully this doesn’t get deleted, because it will probably turn out to be long. Obviously there’s spoilers, I suggest reading it after you watch the episode if you don’t get what happened. I’ll give further warning when I directly translate what the characters are saying word for word.

again, SPOILERS INCOMING

The beginning is all a recap. I’m not too good with kanji but the words just look like a description of each character + a recap at the end. The first scenes are also from the last episode so I’m gonna start from 7:05 after the title screen.

Scene in the House
It’s pretty basic. She’s telling him stop she can’t take anymore the whole time. I’ll just leave it at that.

Bath Scene
It starts with Yui saying “Is this how I should do it? …..Doing all these horrible things to me..” and he responds “That’s right, it’s better than having everyone see you’re embarrassing side” so he’s still blackmailing her. The scene is a pretty basic, resistant at first but by the end she’s like all into it.

Bath Scene 2, I’m gonna directly translate what they say here.
Yui: So Yui is just gonna be your slave huh? Just you’re plaything for the rest of my life…
Tencho: Uh I wouldn’t say slave, I mean, I’ll like, take care of you and stuff.
Yui: So if I do sexual things, you’ll give me money, is that what you mean?
Tencho: R-Right, I don’t mean to chain you down or anything, as long as you’re cooperative.
Yui: I see.. I understand

Confrontation
So then Shiori comes to visit because she think he’s lonely. She’s commenting about how dirty the place is and how he should “really get a girlfriend”. Gonna directly translate lines again, from this scene into the next.

Shiori: Were you taking a shower? I can wait.
Tencho: Uh.. n-no
Shiori: What? It’s not as if a woman’s is taking a shower….

Scene at the table
Shiori: You’re really an idiot, you fat piece of trash!
Tencho: This is um.. well
Shiori: What the hell?! What am I, a girlfriend walking in on getting cheated on?! You jerk!
Yui: ….
Shiori: You got tricked so easily! Damnit, I told you Yui is the kind of girl who sells her own panties!
Yui: Ehhh, Shi-chan you told him all that? That’s horrible!
Shiori: Don’t “that’s horrible” me! You damn home wrecker!
Yui: Home wrecker? Shi-chan you’re like an old lady.
Shiori: Yui you idiot! Closet Pervert! (She says Muttsuri!, which actually more specifically means a person who acs really serious and not perverted, but turns out to be a giant pervert)
Yui: Shi-chan you’re the closet pervert.
Shiori: Gnnngh (Turns to Tencho) Having delusions about High School girls is fine and all, but at the age at fat trash like you is an easy target!
Yui: He said he’ll take care of me for the rest of my life.
Shiori: Huhhh?
Yui: Now I won’t have to worry about tuition fees.
Shiori: Whaaa? You, don’t tell me from that time…

Flashback Scene in the locker room
Yui: What if the guy here was like “You’re mine!” and molested us, what would you do Shi-chan?
Shiori: What the hell! You’re delusions are scary. If you had your first time taken away like that you would be fine?
Yui: If it’s someone I like I wouldn’t care how.
Shiori: I can’t keep up with you. I would want it more like in a bed, embracing each other..
Yui: Shi-chan ew. That’s so not in style nowadays.
Shiori: No, you’re is way too extreme.
Yui: But if I have that happen, he’d feel pity for me, and I think I could just do whatever I want.
Shiori: What do you mean if that happens, what you’re saying is scary. Are you planning on doing this?
Yui: Yup.

So that’s basically everything I thought was unclear. The rest are pretty self explanatory sex scenes. When Shiori is looking at them through the door she says “She’s always taking what I want..” I guess I’ll translate the last 2 scenes for closure.

Yui: Oh yeah, Shi-chan congratulations on your scholarship.
Shiori: Thanks… Although in the meantime you went ahead of me and seduced that trash. Ah, kind pisses me off.
Yui: Aw don’t worry, I’ll share with you.
Shiori: What’s with that superior attitude! I’m the one that did it first.
Yui: But the one he said he’d take care of is me.
Shiori: Ugh Yui you idiot!

Final Scene
Tencho: You need to hurry back or Nee-san will be worried.
Shiori: What was she doing to you??
Yui: C’mon Shi-chan, it’s not okay to bully him. He’s Yui’s Slave-san.
Shiori: Wha- Slave?? Yui!

And I’m sure it’s pretty obvious but the last thing they say in unison is “Mother”.

Sorry if this is a waste of time and everything I said was obvious. I feel like it’s hard to find good Hentai nowadays and I’m a fan of this series, and thought this episode was particularly good, so wanted to share, just in case.

So this turned from fat guy rape into fat guy harem. If you ignore the first and maybe second episode and turn the guy into a young “average” guy, it would be indistinguishable from your usual harem wish-fulfillment. It is also funny how long the adaption is relative to the game so they had to add shit while the longer games has short adaptions so they had to cut out a lot of crap.
