Need help to convince my wife to do it again after doing it once!!!

Yesterday we had an intense sex... we smoked weed together and kept fucking untill we both were exhausted... all the time she kept telling me how she like the guy when we had threesome and how badly she wants to get gangbanged by at least 10 men... she even talked about her ex and one point I asked her if I want her to have sex with a guy that she wants who would she choose and she replied it would be her ex as he had a very big dick...larger than mine....after all the talking we had I thought this she'd actually agree again to do it but once we both got sober, she just told me that it was all because she was horny for last 3 days and was watching gangbang and threesome porns to masturbate... then just told me that she'd get hurt if I ask her to do it for real..so I stopped there
Honestly sounds like my wife. She loves role playing and has flirted with some coworkers but doesn’t like to discuss it when sober 😭
