Almost forgot about this specific sort of jav. Producers are now-a-days stuck at neet sister, wife->hotel or husband->drunk-> ntr/netorare
They could create a poll to take in public opinion on their works!
Bu özel jav türünü neredeyse unutuyordum. Yapımcılar bugünlerde neet kız kardeş, eş->otel veya koca->sarhoş->ntr/netorare'de sıkışıp kalıyor
Çalışmaları hakkında kamuoyunun fikrini almak için bir anket oluşturabilirler!
At first, I just got interested, but while browsing, I remembered this. I think it's a gem as well — SPRD-567
(I'm not sure about the whole dynamics, i.e. if the husband is still present, but the premise is that, yeah, mother has a sex friend. I don't remember the story much, I just remember how great the DVD cover is and how aroused I was when watching it for the first time)
Also, this label (SPRD) seems to have more titles like that, though they might not be in a series strictly speaking; I would just search for 母にはセフレがいるようだ (Seems like mother has a sex friend). Also, to find more like these, I would take keywords from all the titles already shared here and use combine them in different ways
