Rough summary for until subs come out (spoilers, if that exists in hentai)
Picks up where last episode left of (though she has different clothes). Airi is
in 100% dere/possessive mode and claims she wants everyone to know the father
belongs only to her (thus fucking at the entrance of the house so the mom will see
when she comes home. The father is obviously not to keen on this but he says he
“can’t take his dick out” and “can’t stop moving his hips”. When the mother walks in
Airi claims the father as her own and the mother simply says “Well mommy better leave then”
In the scene with Marina, Marina is just longing for dad, and Airi comes and says she can’t have
him cause he belongs to Airi. Marina replies “I guess it can’t be helped but please share him sometimes”
The scene cuts to Sana and Airi and you find out everything after the father gets dragged into Airi’s room
has been a hallucination of the fathers due to a side effect of the drug. Shit got confusing for me here
cause I guess I didnt watch the previous episode very attentively but Sana explains that she told Airi
everything about Yuka-sempai (the new brunette girl from the last episode that Airi flipped a shit about)
And apparently the father is genuinely helping her in some way (I don’t know how) and thus Airi apologizes
for being a bitch, dad apologizes for being mean (from last episode) and they make up. As for the sudden change
in behavior after the alarm rings, Airi says “God that was tiring, 22 minutes is pretty long. Well now dere time is over”
So I guess it as kind of an act, but they did actually make up tho. I dont think i need to explain the sex scenes that follow.

Now for the second half I’m pretty confused but I’ll try anyway maybe it will make sense to someone who has recently
watched the whole series. Basically they bring the story back to Marina boyfriend who if you guys recall knows about
the relationship with her father and they introduce the possibility that the photos sent to the school of Marina at a love
hotel as well as the posts online about how she’s a slut were done by him. I totally missed the point of why Sana is
histerically looking for Airi and breaks down in tears when she finds her. Totally lost to me. Perhaps because of that
the next developments are super confusing to me. Basically somehow the boyfriends stabs the mother as shown in the
flashback. Airi says something like “maybe he mistook her for Marina” but thats still pretty extreme to straight up stab
someone. On the couch the girls are all just talking about their disgust for him. Even Marina when asked by dad if she is okay replies “Why would I care about the piece of trash who hurt mom”

The end seems pretty simple. Basically Sana convinces Airi to let her have a go with dad, and she reluctantly agrees
cause she does feel like she owes her a lot (for telling her everything about the drug and the brunette girl) and is grateful.

I dunno what caused me to write this I always wished there was some easy way for viewers to add subtitles to uploaded works so we can get subs faster, I guess i’m acting on that sentiment. I hope 2 people find this useful.

On a sidenote for people hating how much love Airi is getting, Marina has a comical line in the middle where she’s
sitting on the bed and she sighs and says “I guess I’m sitting out this time too”

That being said you are all crazy Airi is hot as hell and I will never get sick of her. Toodles
