My wife hasn’t touched my dick with her lips in over 8 years now but sucks black cocks pretty much every week. It’s a huge turn on for me, I love it. For special occasions, my birthday, Valentine’s Day, Christmas, she usually brings me along to watch her suck a BBC or two from start to finish, with them cumming all over her face and down her throat. It’s is the best blowjob I’ve ever had and I’m just there watching and waiting for them to finish and leave so she can jack me off and kiss me letting me know if I had a big black cock, it would be getting nice and wet from being sucked but since I don’t and I have a little white dick, her hand is all it will ever feel again (although I’m not denied pussy, but it is rationed to me).
Oddly, all this was my ideal at first and she stuck with it because she can tell how much this denial turns me on.
