DGKD-320S - A couple's daring departure, real swapping with the neighbors

Bringing in a third party or another couple to provide various 'stimuli' is a staple of this kind of 'counseling' genre. Naturally, works in the same genre end up being quite similar. So, it really comes down to the direction and the quality of the actresses. Both actresses are quite high-quality, and their techniques during the scenes are good enough to keep you excited. The flow isn't much different from your average AV, but it hits all the right notes, so it's not exactly boring.

Setting the 'wife' aside (lol), the husband really seems like an amateur. It starts with one couple trying to have sex, but they can't quite get it right. So, they bring in another couple; watching the wife being pleasured by two men at once causes the husband's demeanor to gradually change. Enticed by the other wife, they suddenly dive into a 4P session. Both wives have a nice, curvy build, which is erotic, but the clinginess of the other wife is particularly stimulating. There's plenty of 4-way action, so I was fully satisfied.
