Ok so I have this question for u ladies

Me and my husband even married for 18 solid years. And I’ve been fantasizing about a 3 some, (note he has never cheated on me) from what I know lol. I am currently prego 7 months. And being prego I’ve been the horniest . So I was thinking about having a 3 some with me my husband and a girl we’ve both known for about a year she’s kool down to earth chic. Me and her exchanged a pic or 2 on Snapchat, if u know what I mean🍑💦 I want to see if my hubby is down and if she’s down just for fun no strings attached so what do you ladies think? What’s your opinion?
