Duane Knaus by Western Photography Guild.
In my salad days, photos of models wearing posing pouches were fairly common. For me, If the model's bush peaked out over the top (or the side) of the pouch it was like a cherry on the top of the sundae. Here, Duane and WPG gave us both -- top and side. A twofer!
Speaking of twofers, I'm not sure which photo is the reverse image of the actual photo.
