Wife got pregnant by a rando.

My wife went on a girl’s trip in December. She had an unprotected DVP with two guys she hooked up with in Vegas. She’s pregnant and we don’t know or care who the daddy is. I’m not upset and find her slut pregnancy very hot. So does she and she’s been horny as shit since finding out. She still wants to fuck other guys while pregnant and I’m letting this happen as long as condoms are worn . Anyone ever have their wife knocked up by another guy?
