PAP-213 - 性生活アドバイザーが教える！熟年カップルの悩みを解決します！

I wondered what 'advisor' meant, and it turns out it's a veteran male AV actor having sex with the actress playing the wife, and then some wife-swapping. Honestly, I'd rate it a 4.5 (rounded up). I give it 5 points because the male actor is skilled, but 4 points because it's a compilation, so it feels a bit disjointed. Averaging it out, 4.5.
