OYC-146 - Wife at a Wine Tasting: Will She Cheat with a Hot Sommelier?

They categorize them as 'innocent wife,' 'big-breasted wife,' 'gentle wife,' and 'cheerful wife,' but other than the big-breasted one, I can't tell them apart. Whether it's the way they talk, kiss, moan, or react after ejaculation... I don't see any difference. Besides, no matter how handsome the guy is, it's neither funny nor interesting that they'd just get in the mood immediately after a few glasses of wine and a hug. If I had to point out a good part, the 'innocent wife' (Yukari) is pretty, and it was exciting to see her slender body writhing with her underwear peeking out from her skirt. The second one (Yuko) was fun to watch when she went from cowering in shyness to making a lewd face the moment he started caressing her breasts. So, the message is that married women will 'happily cheat if given the chance'?
