What are things the wife can do to tease or flirt with guys that can be done around the house?

Me and her got lingerie and more revealing clothing on Sunday. Not everything I wanted but I was going to order stuff. I think she enjoyed it. She wore what I got the first time yesterday. I wanted to do this because I love how it looks but I wanted to experiment with her dressing slutty and flirting more but not with us having the intentions of her fucking another guy. I was thinking of ways that she could do that with the lingerie or anything else around the house with any male company without making anything awkward in the future for people we know or seeming weird. Example: the pizza dare. I wouldn't care if she did it but I would be embarrassed to be around. Awkward would be me telling her to kiss or grind on a friend or male family member but I would like to do something with the lingerie or her wearing something she was flashing them in. If it naturally led to groping or something I wouldn't care.

I've thought of maybe just steering a conversation towards sex around any male company she was into to get her turned on but I don't have any good ideas how to go about it.

Are there any things you've done like this or just ideas?
