Me and the wife have quite a broad and I suppose kinky sex life.
But, she has always said facials are a complete no go.
However, the other night, the wife was sucking and wanking me while I straddled her. When I came it just missed her face n hair.
I asked what would she have done if it had gone in her, face she said she’d just wipe it off.
I know if I ask to do it, she’ll say no, but if its an accident, then she seems like she’ll be ok.
Is it ok to do it “accidentally…?”
I think you know the answer, and by posting evidence on here we all know it won’t be an accident 
Has she said why she doesn’t like the idea?
If you know she would say no and you do it anyway that makes you a complete douchebag (and I’m being polite there).
Genuine accidents happen and it’s good (for you) to know that it wouldn’t completely traumatise her if it did happen but that doesn’t give you a green light to fake an accident.
It might put her off sucking and wanking you. 
No. It shows a lack of respect to your wife in my opinion.
She has clearly said no so if you try and manipulate around that, how can she trust that you will respect any other limits she has?
I’m with @Calie on this 100%.
Simple answer no. Seems that you have a lot to lose by considering this action and very little to gain. Bad idea.
Im also with the other guys here. Don’t be a d*ckhead and be disrespectful. What’s so wrong with having a normal adult conversation about it? Bring it up and if she still says no, then unfortunately you’re just going to have to live with that.
I agree with everyone else no means no, finding a “loop hole” like say oh it was a accident just makes you disrespectful and un-trust worthy. If it’s something that means that much to you sit down and communicate it and talk about it but don’t try to find a work around no means no.
I must say I have never seen the fun, excitement what ever you want to call it of finishing over the face. I’ve never done it and doubt I ever will. If its not for her you must NOT do it would be my advise.
Do not overlook the importance of consent.
If she doesn’t want it, do not do it.
NO, you should absolutely not do that. Neither on purpose nor ‘‘by accident’’.
Honestly, if this happened to me the guy would be out the door before he had finished cumming. 
100% agree with everyone else.
Me neither, never been something I’ve been into
Absolutely not by “accident”. She is showing you the most trust anyone can show another person by having sex. Break that trust and it has a massive effect on the dynamic that already exists and is completely disrespectful.
Are you for real?
These posts annoy me, you know very well the answer to this even without asking, no means exactly that… NO! Maybe learn to have some respect towards your wife?
As with anything sexual, its about consent and if someone says no to something and you do it anyway you are going against her wishes and in my opinion lack of respect towards her.
If my OH did anything to me without consent or I said no, he’d be straight out the door.
the other way round more of a turn on for me, her cumming on my face 
or is that just the sub in me
Her main put off is if goes in her eyes.
She doesn’t actually mind the face bit.
I think she’s also put off by the idea if it being too slutty.
Head to neck I can cum anywhere.
Just not the face.
I figured if she’s the one controlling it, then maybe she’s secretly wanting it.
She didn’t stop the hand job, and didn’t even flinch with the near miss.
I’m with you there.
I love her coming in my face.
I think that’s the other thing.
I think she associates with porn, but I don’t terribly like porn. I like to be with someone. If I need a wank I’ll just crack one off.
I really think its the eyes thing.
I could buy her goggles!!
Also, apart from it being porny, is there another reason you don’t want it?
