That's Wifey with a wig. They've done a few of those playing with the idea of Hubby getting off with Wifey's "sister".
A number of these "husband and wife" teams are pretty monogamous. I've never seen Dawn from Dawn's Place doing anything with anyone other than her hubby either except for maybe one softcore posing set she did with another girl for Score or some similar mag.
75% of Wifey's appeal is that she fucks and sucks just one guy, her husband. And vice versa. Thats why I pop boners to it. Sexually speaking, she's everything you want in a wife. Horny, eager, creative, swallower. Hence...Wifey.
Personally, I prefer a spitter... Hey, I like to make a mess. But I do agree. I think the whole fidelity and monogamous thing turns me on intellectually.
