My Wife's Idea of a Good Time

You haven't met my wife, so let me explain her: She is terribly thin. I mean, I actually worry about her. Maybe she's anorexic, maybe not. She is rather strong and healthy though. She's also kind of tall at 5' 10." To my delight she likes to shave the reddish-blond hair over her pussy. She has a very specific thing she likes and, I have to say, I really like doing it for her. We have a massage table. We will turn up the heat and then, about an hour later, we get naked. She climbs on the table, and I begin. She lays on her stomach with her legs spread wide, feet and lower legs hanging over the edges of the table. This is so I have perfect access to her pussy and asshole. I'm so attracted to her and, especially, her asshole. I just can't stop looking at it; I even think about it when she's not available. I mean, after three years of marriage, you'd think I'd get over it, but no! As she settles onto the table, I take a moment just to stare at her asshole; and of course, I get hard right away. But it's not about me. In fact, I like having what I call an unrequited boner. I won't masturbate and won't cum during this session, and that's the way I like it. Slowly, I just stroke with the tip of my index finger around her anus. I do it for quite a while and she moans, "hmmm!" Eventually, I get a hold of some coconut oil and spread that around her anus. But I don't put my finger inside. I don't even touch the center, not for quite a while. Finally, I do touch the center and she almost has an orgasm just from that. In time, I work the tip of my finger into her anus. Then slowly, ever so slowly, I work my finger all the way in. Sometimes, I'll add a second finger, sometimes not. After a remarkably long time, I have her flip over on the table, and put her legs over her head. Then I put a finger back in her butt, and start working her inner labia with my other hand; everything is covered in coconut oil, of course. I just slip her labia through my fingers over and over again; sometimes pulling slightly, sometimes just slushing them around. It becomes clear that she's close to cumming because the little button on her clitoris starts sticking out of the labia just a bit. Finally, I get around to rubbing that delicious clit of hers, and bang! She cums! She cums really, really hard. I'd almost call it convulsing. In fact, with my free arm, I have to restrain her so she doesn't throw herself off the table. Without further stimulation from me, because it would literally be too much for her, she continues to orgasm for as much as a whole minute. While I hold her on the table with one arm, my other hand still has a finger in her ass. I feel her contractions and, in time, they subside. That's it. She's not like other women I've met, who can orgasm over and over again. That one huge, crashing orgasm does it for her, for at least a day. Then, a day or two later, we'll repeat the process in almost the identical way. Each time we do it, it's as if it is the first time. Like I said, I just can't get enough of her asshole. Lately, she'll reciprocate and do a similar process for me. She seems to like my asshole too. Here's the odd thing: we've come to like this so much, we seldom have regular sex. I don't miss it a bit.
