Ladies who like anal...

Hey ladies...so for those if you who like anal quick question. My husband is huge..like a little wider than a soda can...so we don't do anal penetration. We play but no penis inside. He has always wanted to cum inside my ass. If we use toys and what not then have him cum right against the opening do you think it would go up inside ?? It is something he fantasizes about all the time so trying to figure out a way to make it happen. Thanks
