My wife has an 8" dildo that she uses; while we are fucking she'll bring the dildo up to my mouth and have me lick and suck it. Does this mean she would like to see me sucking a real cock? She has done this on several occasions and I of course do as she wants, but afterwards there is nothing said. I'm not sure how to even bring up the topic since I do not want to sound like I want to do it but all the same it would turn me on to suck a cock while she watches.
No it doesn't - it means she wants you to taste wherever the dildo has just been (her pussy?). There can be all sorts of roles and fantasies within sex, particularly if a woman starts using a strap-on - however that is a looooong way away from a wife wanting to see her husband sucking a cock. If you want to introduce that kind of theme, perhaps you could try buying some bisexual porn and watching it together. If that gets a positive response, then you could start a discussion... but these are HUGE steps within a relationship.
When I do start to lick and suck on the dildo she really starts to moan and get really excited. I know I am fucking her but it seems like she is getting excited at seeing me lick and suck the dildo. Would she do that just because she wants me to lick her juices off of it? To a guy like me her excitement tells me something else, but that is why I am asking other women what they think.
Honestly.. it could mean anything..or nothing.. You might try just asking her in a nice non-confrontational way and assure her her honest answer won't be met with derision or anger.
Agree, it could mean anything. maybe even that she wants you to liubricate it to use it where ever you are not currently fucking her with your cock.
It means she wants a 3some and wants to watch you suck cock.
