A couple thoughts:
All you have here is evidence of Mom indulging a fantasy. BBC porn and dildoes does not an affair make (unless your father is really strict about things). So probably not something to stir the pot over.
And for all you know, you father is good with this. Gives her an outlet and maybe he gets off on her doing it. Maybe they even have an open marriage thing going. So, again, not something to stir the pot over without having more information.
Really, unless you uncover hard evidence she is fooling around, you're going down a risky path by continuing to investigate. Maybe let it sit for a while and see what else comes up. This could all be part of your parents' regular sex life and you've just stumbled on to it.
Okay thank your sir for your help. But there are some other things I didn't mention because I was too nervous. Mom has a gym buddy, muscle handsome guy in his 30s. And he's black. So it's a reason of my suspicion. It is possible that her fantasies are not so unreal. So I'm worried. But I understand your main message: I must not make hasty decisions. I won't, I just want to sort out this whole situation.
