Well, a few things. As you know IR footage really counts here (happy to make some with your wife's lovely Hoosier Booty...I mean body). Realize you're more curious than experienced so we'll waive the IR Footage requirement this time only...next time...
LOL
First off, she must know she has a truly MILF bikini body built for BBC fucking (from the neck down - hey, that's all we can see here) if she has the ovaries (not balls) to ask for a public opinion. I'm going to assume her facial features are just as appealing as her statuesque 5'8 body. I wouldn't refer to her as a phat ass, for some reason it doesn't roll off the tongue like it should. She's definitely got a Booty, good for palming in public (Right,
@Mr&Ms TopCat?) and kneading all night...probably spreads nicely on all 4s which would deserve some light paddling...and rimming. Lingerie choices accentuate her cheeks. And those hips are perfect for grabbing and pounding as long as she can hang in there. Her breasts? Make her look 14 years younger. Wouldn't change a thing. Her ink suggests she might have a creative mind...good for exploring and a high threshold for pain.
Finally - Bikini body comment. If she's walking on the beach, pretty much 90% of the dudes on the beach are going to sneak a peek through their shades or squint and look away while they're with their wife or significant other. They wanna see how that body saunters on the beach.
One other thing...when you're more than curious, you might need to leave Indy and come east, although
@curvywife might dispute that.
