My tongue seems to be one of my better trademarks. For the most part, I seem to be able to penetrate a guy's ass some. I love rimming - to me, it gets the ass ready for a fuck. I have rimmed a lot of guys who do not like getting rimmed but they enjoy it from me. What matters is - if you enjoy rimming & have no qualms about it - the person you are rimming should enjoy it as well.
I do not get fucked & I get rimmed every so often. I have met a handful of guys that I enjoy getting rimmed from, but for the most part - it does nothing to me.
I usually start off slow & let the ass relax some. I can usually spread the cheeks some & then I am able to enter the ass some. Just practice & work those tongue muscles some
