My wife has a natty badonkadonk on a small frame; and for some reason, it is other women that get intentionally groppy with her.
I've seen it happen multiple times with her friends. It's usually just a quick passing squeeze; but one time a drunk friend just couldn't seem to keep her hands off her ass. While her boyfriend and I watched in astonishment lol!
Usually she just laughs it off. The only time it actually embarrassed her was at the nudist resort. A friend of ours was standing next to her with her arm around her waist; and I guess she couldn't resist grabbing an asscheek. I thought it was hilarious. But because she was naked and having a cheek grabbed exposed her asshole to the people behind us; she wasn't quite as amused lol!
