What happens in Vegas....

#flawless • Mommy to a handsome little man. And happy girlfriend to a sexy man ;)
So my BF of almost a year and I are going to Vegas soon.. Just the 2 of us.. It's the first real trip we take together and I want it to be memorable, fun and super sexy...
Now I've had a few threesomes before and he never has ... I know it's one of his fantasies and I'm thinking of fulfilling it.. Never thought I'd ever consider this.. Ever.. But I really think he's the one.  But I've seen his porn preference.. And I don't want him to look back and feel like he missed out.. Plus I'd really enjoy it too.. I would never do it with a woman we know, it would have to be a stranger that I know we will never ever see again , and Vegas just seems like the perfect place.. 
Anyone of you ladies done this for your man? How did you choose? We're there any negative consequences? Do you regret it? Did it make you hurt? Was it worth it? I'll take all the advice I can get 😄😄
