Only you know how she will react when she's not ....... Try talking to her while your in bed massaging her again.
Tell her she deserves the pleasure a large cock can give her.
I think your wife should understand this is strictly about you enjoy her getting off. I wouldn't attempt to kiss her. however, I would make sure she cums!
That's the best way to break the ice! That's exactly how I broke the ice as well. Leads to Great sex! Definitely introduce a nice size realistic Dildo !
a nice size good quality lifelike dildo will differently make her remember any big cock she ever had, if she's never had big cock it will make her curious and horny for it
