Size?

If he's confident and secure in his own skin, he should be fine. My wife has a whole collection and a good half of them are bigger to MUCH bigger than me. If you look up a thing called "the Funky Rocker", I've made one for her and she loves it. I went so far as to add the "DP" elements and I simply love watching her ride that thing. Go for it! I would suggest however that after you get yourself off for his viewing pleasure, offer up whatever hole can take some more and make sure he knows you still prefer the real thing. Good luck!

He might be hurt at first but will eventually accept it.

It's hard to say how he will react, myself I understand that it feels good for some women to be stretched around a huge toy. My wife is a size queen that loves enormous dildo's, I don't have a problem with that, and I love to watch her masturbate using a big toy, and using them on her. My wife weights 105 lbs. On a good day, her pussy is really big, hairless and loose. I love how big her pussy is and how much she can stretch open, her asshole is always tight for me

He won't be offended. He will probably like the big dildo you get. Have him suck it for you for awhile before he puts it in your pussy. Then have him clean your pussy off that big cock once you cum on it

It is 12ins long and 9ins round with a big shine red end cant wait to get it all in my wet hairy pussy .

How big is it?

I would use it on you while you suck my cock. Stretch you out wide and then drop a huge load deep inside you.

That sounds nice
