Sorry for you that you have a tiny cock, but be glad that at least your wife is happy now that she knows what she was missing. Seems like you are not going to get to fuck her anymore.
Maybe you should introduce her to anal and see if she will let you fuck her ass while a real cock pounds her pussy. Or maybe you could lick her ass as a big cock fucks her, then lick her clean, or take his spunk in your face.
