Looking for input on a Chastity or Cuckold weekend scenario

Hello everyone. I frequent this place occasionally but haven’t posted before. My background with chastity varies, ranging from quite intense to more moderate experiences. Currently, I’m in a spot where community feedback would be really helpful. A lot of what you see online feels unrealistic, so I’m hoping for some grounded suggestions. I have a friend who lives far away and also has some experience with the lifestyle. She and her husband have experimented multiple times; long-term arrangements don’t quite suit her, but they like short-term play. Since I’ll be nearby, we’re considering a cuckold weekend. Our focus is primarily on the physical aspect, and it offers her husband a chance to enjoy that cuckolding rush as well. We want suggestions that aren’t overly extreme since she isn’t keen on him being treated like a slave while she gets her toenails painted during sex acts or sits in a tub waiting for us. We’re looking more toward actions she can take (or have him perform) that excite the cuckolding dynamic without going overboard. Happy to hear any thoughts. Thank you.
