Not sure where the wife learned it.. and don't care. First time together she swallowed my entire shaft as I came down her throat . Ever since she does it all the time. And she can handle it hard. about a month ago she asked me for face fuck her. One of the hottest things ever! . What's even better is when she chipmunks me.. sucks both of my balls in her month.. haha
My wife practiced with a toothbrush so she wouldn’t gag way back in our college days when she earned the nickname the blowjob queen. My fwb and fb both deepthroat with ease. They are 52 and 60 respectively and have been with dozens of men each. As I have written on other posts all three deepthroat and suck without using their hands and stroking. I like my cock sucked and deepthroated as opposed to some who suck the head and are basically giving me a handjob. I have been with dozens of women and while I will of course enjoy my cock sucked I love the deepthroat. They have always been open about their pasts as have I but I find it a turn on thinking of their mouths and tongues and hands working on all different size cocks and swallowing their loads or letting them cum on their hands face body.
I grew up with older sisters, so I kind of knew from an earlier age about blowjobs. So once I got to the age I'd be having sex, I'd do lots and lots of practice with other objects.
Having a small mouth, I've found it challenging to get a guys entire cock inside my mouth. For that reason I've been working on taking cock deeper each time I suck one. I can take my regular FB into my throat now. But, the FB I was with today has more girth and is a lot more difficult. I did get several strokes that got his cock pretty deep this time - almost the whole thing. I told him my goal is to get him into my throat.
