Katainaka ni Totsuidekita ○-ssia Musume to H Shimakuru Ohanashi

Both have similar girls, busty, curvy, blonde and naive, they get tricked by the protagonist in both to get sexual relations with them, since both OVAs are made by Collaboration Works the animation and artstyle is very similar, cute faces with curvy body in both, in Katainaka Ni Totsuidekita there's cheating involved, but it's set from the protagonist point of view, since he's the one having the affair, so after all both are vanilla hentai with similar characters at play and a similar plot about tricking the female protagonist, I recommend both of them. 

If you like cheating in your hentai, or being more specific, when the main protagonist is the one doing it, then you may like both of these, the protagonists are identical, both are douchebags that are jealous of their more successful brother (brothers in Aniki No Yome-san) and end up lusting over their sister in law, to later do the deed, both are basically a great example of what netori is about. 

Visually similar characters--beautiful, blonde, huge boobs.
